Understanding Solar Inverters: String vs Micro vs Hybrid
Inverters convert DC solar power to usable AC electricity. The right choice significantly impacts system performance and monitoring capabilities.

Inverter Basics
Solar panels produce direct current (DC) electricity, but businesses use alternating current (AC). Inverters make this conversion and significantly influence system performance, monitoring, and reliability.
Inverter Types Compared
| Type | Best For | Cost | Monitoring |
|---|---|---|---|
| String | Unshaded roofs, budget | Lower | System-level |
| Microinverters | Complex roofs, shading | Higher | Panel-level |
| Hybrid | Battery integration | Higher | System-level |
| Optimizers + String | Partial shading | Medium | Panel-level |
String Inverters
Most common for commercial installations:
- Lower cost per watt
- Easier maintenance with ground-level access
- Shading affects entire string performance
- Typical lifespan 10-15 years
Microinverters
Panel-level conversion:
- Each panel operates independently
- Shading affects only individual panels
- Higher upfront cost
- Panel-level monitoring included
Hybrid Inverters
For battery-ready systems:
- Manage solar and battery in one unit
- Future battery addition without replacement
- Higher initial investment
