SolarEdge is the most-installed inverter brand on UK commercial solar installs above 30 kW, ahead of Fronius, SMA, Huawei, and SolaX combined. Most of that market position comes from one decision the company made in 2010: every panel in a SolarEdge array gets a small power optimiser bolted to its frame, and that optimiser reports its own voltage, current, power, and temperature back to the inverter every few seconds. The result is a monitoring platform that lets you see exactly how each individual panel is performing — not just the array as a whole, not just the string, but every single module. For commercial sites that ranges from a 30-panel rooftop on a small office through to a 1,200-panel warehouse array, that resolution is the single biggest reason SolarEdge dominates the warranty-grade end of the inverter market. This guide explains how the platform works in 2026, how to read the dashboard, how alerts work, how to get data out for energy reports and warranty claims, how the API works for integration with Slack or MS Teams or BI tools, and how SolarEdge compares to Fronius Solar.web and Huawei FusionSolar.
How SolarEdge monitoring works
The architecture is simple. Each panel gets a power optimiser (P370, P400, P500 or P850 depending on panel wattage), and the optimisers communicate over the same DC cable that carries the panel output up to the inverter. The inverter aggregates per-optimiser data and pushes it to the SolarEdge cloud over Ethernet, Wi-Fi, or cellular. From there the dashboard at monitoring.solaredge.com and the MySolarEdge mobile app pull the data for display. Data is stored for the lifetime of the system — there is no rolling deletion at 12 months or 5 years, your 15-minute resolution data from 2018 is still queryable in 2026.
Per-panel data resolution: voltage, current, power, temperature, all sampled every few seconds at the optimiser, aggregated to 15-minute averages for storage. The 15-minute resolution matches half-hourly metering granularity used by UK suppliers, which makes import-export reconciliation straightforward when needed for SEG income verification.
The MySolarEdge dashboard — what you see
Production view
The headline screen is a power-flow diagram showing the current state of your site: panels generating X kW, inverter converting to AC, building consuming Y kW, grid importing or exporting Z kW (when a smart meter or production meter is integrated). Below it sits today's generation as kWh, this month's total, and lifetime cumulative generation. A simple stacked area chart shows generation versus consumption versus grid flow over the last 24 hours, which on a sunny day for a self-consuming office is a near-textbook curve.
Equipment status
This is the layout view that visualises every panel in your array as a coloured rectangle. Green means producing within tolerance, yellow means mild underperformance, red means offline or fault. Click any panel to see its lifetime production, current production, voltage, current, temperature, and time since installation. For commercial portfolios this is the single most useful view — a yellow tile spots a soiled or shaded panel before its underperformance shows up in the headline annual yield.
Power flow
An animated diagram showing PV → inverter → loads → grid in real time, particularly useful for first-time site owners who want to understand at a glance whether they are net importing or exporting at any given moment. The arrow direction reverses through the day as the sun moves and as office loads turn on and off.
Savings calculator
Under the dashboard's Savings tab the platform calculates running cumulative savings based on a configurable import tariff. Set this to your actual blended import rate (most UK commercial customers should set this to the half-hourly weighted average from their last bill, typically 21 to 28 pence per kWh on standard tariffs in 2026). The calculator distinguishes self-consumed kWh (saved at full import rate) from exported kWh (earned at SEG rate, typically 9 to 15p — see our /seg-tariff-comparison/ page).
Environmental impact
A reporting view that converts kWh saved into kg CO2 avoided (using the latest BEIS conversion factor — 0.193 kg per kWh for grid electricity in 2025), tonnes saved in equivalent miles driven, and tree-equivalents. Useful for ESG reports and for Net Zero corporate disclosures — see our work on /commercial-solar-pv/ for the underlying business case.
Alerts and notifications
SolarEdge generates alerts in five tiers, configurable in the dashboard's Alerts settings. Configure these properly at handover — the default thresholds are conservative and generate too much noise on a busy commercial site.
Low production alert. Triggered when daily generation falls below an expected percentage (default 50 percent) of the modelled value for the day. Useful for catching widespread soiling, a tripped MCB, or a complete inverter offline event. We typically tune this to 70 percent for offices and 75 percent for warehouses where the load profile is more predictable.
Optimiser fault. An individual optimiser reporting a hardware error code (typically over-voltage, over-temperature, or communication failure with neighbouring optimisers). Trigger raises a warranty case automatically with SolarEdge's UK service centre.
Inverter warning. Lower-tier inverter event such as grid voltage out of tolerance, isolation fault on the DC side, or temperature derating. Often self-resolving but a recurring pattern points to a real underlying issue (loose terminations, marginal grid voltage from the DNO).
Communication loss. The inverter has stopped uploading data. May be a router rebooting, ISP outage, or an actual inverter offline event. We recommend a 4-hour delay on this alert before email notification — short outages are common and not actionable.
Custom alerts. Per-string production thresholds, per-optimiser rolling 7-day averages, and arbitrary KPIs can all be set up. Most commercial sites benefit from a per-string threshold to catch single-string failures (a popular failure mode where a single string falls offline and you do not notice for weeks because the array still produces 90 percent of expected).
Data export — warranty claims and energy reports
From the professional monitoring portal click the Reports tab. Three export modes are useful:
Energy report (PDF). Auto-generated monthly summary report, emailed to site owners on the first of each month. Shows production, savings, CO2 avoided, equipment health summary, any open alerts. Useful for property management companies, multi-site owners, and ESG officers who need a consistent monthly snapshot per site.
Per-panel CSV export. 15-minute resolution data per panel for any chosen time period. Each row is a timestamp; columns are panel-by-panel power readings. This is the file you attach to a warranty claim when a panel is consistently underperforming. SolarEdge UK service requires 90 days of contiguous data showing the underperformance trend before they accept a warranty replacement claim — the per-panel CSV proves the case.
Aggregate generation CSV. 15-minute or hourly site-total generation. The file structure exactly matches half-hourly meter data, enabling direct comparison against import-export records from your supplier for SEG income verification.
API and third-party integration
SolarEdge offers a public REST API at monitoringapi.solaredge.com for third-party integration. Authentication is by API key generated in the portal Settings tab. Common integrations include:
Zapier. Out-of-the-box Zapier integration: trigger an action when an alert fires, when daily production falls below a threshold, when a new system is added to the portfolio. Common workflow: alert fires, post a message to a Slack channel for the maintenance team. Setup time: 15 minutes.
Microsoft Teams. Via Power Automate (formerly Flow) using the SolarEdge connector or via custom HTTP polling of the API. Alerts route to a dedicated Teams channel for the facilities team.
BI tools (Power BI, Tableau, Looker). Pull daily generation totals via API to feed into operational dashboards. Useful for multi-site portfolios where SolarEdge's organisational dashboard is too restrictive — the raw API data feeds custom reports comparing site performance against modelled expectations.
SCADA and ERP systems. Larger commercial sites with industrial SCADA (in factories or data centres) feed solar generation directly into the building energy management dashboard. Done via REST API polling at 5-minute intervals.
How SolarEdge compares to Fronius Solar.web and Huawei FusionSolar
The honest comparison: all three platforms are credible, all three are used on UK commercial installs, the platform should be chosen at the inverter procurement stage rather than retrofitted later. Differences:
Per-panel data. SolarEdge: native (every panel has an optimiser). Fronius Solar.web: not available — string-level only. Huawei FusionSolar: optional via Smart Module Controller. For warranty claim speed and fault location accuracy, SolarEdge is materially faster.
String-level data. All three platforms give string-level data. SolarEdge breaks each string further into per-optimiser sub-data; Fronius and Huawei stop at the string.
Reporting. All three offer monthly PDF reports, CSV export, and a mobile app. Fronius Solar.web Premium has the cleanest multi-site portfolio dashboard for installers managing 20 plus sites. Huawei FusionSolar has the strongest battery-storage integration for sites running Smart String ESS.
API. All three offer REST APIs. SolarEdge's API documentation is the most mature; Huawei's is the rawest. Fronius sits in the middle.
Hardware lock-in. All three platforms only monitor their own inverters. Switching platforms means swapping inverter — not viable on an existing system. See /best-commercial-solar-inverters/ for the inverter comparison context. See also /string-vs-microinverter/ for the architectural choice between SolarEdge optimisers, Fronius string inverters, and microinverter alternatives.
Inverter compatibility
All SolarEdge inverter ranges work with the monitoring platform. HD-Wave residential single-phase covers 3kW to 10kW, often used on small commercial sites where three-phase is over-spec. Three Phase commercial range covers 5kW to 100kW per inverter, the workhorse on UK commercial installs from 30kW to 500kW (paralleled). Genesis Three Phase covers 100kW to 330kW per unit for large commercial and small utility installs. StorEdge platform integrates DC-coupled battery storage with the inverter, monitored as one system; this is the recommended architecture when adding battery storage to an existing SolarEdge install — see /services/battery-storage/.
Historical data retention and warranty validation
SolarEdge stores per-panel monitoring data for the lifetime of the system at 15-minute granularity. There is no rolling deletion. This matters for warranty claims because the SolarEdge product warranty on power optimisers and inverters is 12 to 25 years depending on product line, and the workmanship warranty plus the panel manufacturer's product and performance warranties run to 25-30 years. When a warranty case opens 8 years into the system's life, the historical data is still in the platform. We have personally raised warranty cases referencing data from 6 years prior — replacements were granted within 4 weeks. See /commercial-solar-warranty/ for the broader warranty framework.
Troubleshooting common SolarEdge monitoring issues
Inverter not connecting to Wi-Fi. SolarEdge inverters use 2.4 GHz Wi-Fi only — not 5 GHz. If your business Wi-Fi is dual-band, ensure the inverter is connecting to the 2.4 GHz SSID. Mesh networks sometimes auto-steer connections to 5 GHz which fails silently.
Persistent communication loss. Most often a dead Ethernet cable terminator, a switch port failure, or a router that has been factory reset. Check Ethernet first, escalate to cellular plug-in if persistent — see our /services/maintenance/ contracts for retainer-based monitoring oversight.
RS485 connection errors (multi-inverter sites). SolarEdge inverters paralleled across multiple units use RS485 daisy-chain wiring. A loose terminating resistor at the end of the chain causes intermittent comms loss. Confirm 120 ohm termination at the last inverter on the chain.
Optimiser pairing fail. After firmware updates, optimisers occasionally drop pairing with the inverter. Resolved by re-running the pairing routine from the inverter front panel — typically 4 minutes.
Commercial install best practices
Three rules we recommend on every SolarEdge commercial site:
Separate site owner account per system. Do not put 10 sites into one site owner login — the dashboard becomes unusable. Use the organisational view for multi-site portfolios, with a single login per site for site-specific access. The organisational dashboard requires a SolarEdge professional partner account on the installer side.
Cellular backup on remote sites. Warehouses, remote farms, and some industrial estates have unreliable Ethernet uplinks. Spec the SolarEdge Cellular Plug-in at install — 250 to 350 pounds upfront, eliminates 90 percent of communication loss alerts.
Configure the savings tariff correctly at handover. Default is 30p per kWh which overstates savings for most UK commercial customers. Set to your actual blended import rate. For sites on TUoS / DUoS half-hourly tariffs (most over 100 kW peak), set to the volume-weighted average — see /tnuos-duos-charges-2026/ for the underlying tariff structure.

SolarEdge monitoring — common questions
How do I access SolarEdge monitoring as a commercial site owner?
Your installer registers the system on the SolarEdge monitoring portal at monitoring.solaredge.com using the inverter serial number, then transfers ownership to you as the site owner. You receive an invitation email, set up a password, and access the system via the web portal or the MySolarEdge mobile app on iOS and Android. For commercial portfolios across several sites, the SolarEdge monitoring platform offers an organisational dashboard that aggregates all sites under one login. Ask your installer to set you up with site owner access at handover, not just dashboard view access — without owner access you cannot raise warranty claims, change alert thresholds, or add additional users.
What is the difference between MySolarEdge and SolarEdge Designer?
MySolarEdge is the consumer-facing monitoring app aimed at site owners — it shows current generation, today and lifetime production, savings estimates, environmental impact, and a power flow diagram. SolarEdge Designer is the installer planning tool used before installation to model expected production, run shading analysis, and design the array layout. The professional monitoring portal at monitoring.solaredge.com sits between the two — it holds the engineering-grade data including per-panel optimiser status, voltage and current readings, fault codes, and historical event logs. Commercial customers should hold credentials for both MySolarEdge and the professional portal; the engineering data is what matters when raising a warranty claim or diagnosing an underperforming string.
Why is one of my SolarEdge optimisers showing yellow status?
Yellow status on the equipment view typically means a non-fatal warning — most commonly a panel showing reduced output relative to its peers. Causes range from soiling on that panel, partial shading from a flag pole or chimney, a degraded panel-to-optimiser cable, or in rare cases a failing module. Open the per-panel view, check the production over the last 30 days against the array average, look for a consistent shortfall versus a one-off bad day. If a single panel is consistently 8 to 15 percent below its peers, raise a warranty inspection — SolarEdge optimiser warranty is 25 years and the per-panel data is exactly what supports the claim. Red status means the optimiser is offline and needs an installer visit immediately.
Can I export SolarEdge data to Excel for energy reports?
Yes. From the professional monitoring portal at monitoring.solaredge.com, navigate to the Reports tab, choose your date range and granularity (15-minute, hourly, daily, monthly), and export to CSV or Excel. Most commercial sites also benefit from the SolarEdge Energy Report PDF which is auto-generated monthly and emailed to site owners — useful for ESG reports, annual sustainability disclosures, and DSCR covenant compliance on financed systems. The 15-minute granularity matches half-hourly meter data so you can directly compare generation against import-export records from your supplier.
How does SolarEdge monitoring compare to Fronius Solar.web and Huawei FusionSolar?
SolarEdge is the only platform that gives true panel-level monitoring as standard, because every SolarEdge install includes a power optimiser per panel. Fronius Solar.web gives string-level data, which is one resolution coarser — you see the eight-panel string is underperforming but not which panel within the string. Huawei FusionSolar offers panel-level data only when paired with their Smart Module Controller, which is an optional add-on. For warranty claim resolution and quick fault location, SolarEdge per-panel data is materially faster — typically saves a half-day site visit per fault. For straightforward whole-system monitoring with mature reporting, all three platforms are credible. The platform should be chosen at the inverter selection stage.
Which SolarEdge inverters work with the monitoring platform?
All SolarEdge inverters since 2014 work with the monitoring platform — HD-Wave residential single-phase, the Three Phase commercial range from 5kW to 100kW, the Genesis Three Phase from 100kW to 330kW for large commercial and utility, and the StorEdge platform when integrated with SolarEdge Home Battery or DC-coupled batteries. The platform automatically detects the inverter type when you register the serial number. Early SolarEdge inverters from 2010 to 2013 require a firmware update before connecting to the current monitoring platform — your installer can update over the wire on a maintenance visit.
What if my SolarEdge inverter loses internet connection?
The SolarEdge Communication Board buffers up to 7 days of monitoring data locally. When connectivity is restored, the inverter uploads the buffered data and your dashboard catches up automatically — no data loss for short outages. For sites where reliable Ethernet or Wi-Fi is not available, the SolarEdge Cellular Plug-in (a 4G modem) is a 250 to 350 pound add-on that gives independent connectivity with a low-rate SIM card. For larger commercial sites we recommend Ethernet primary with cellular backup — communication loss alerts are otherwise the most common false alarm.
