If you’re planning to go solar, choosing the right solar inverter is as important as picking your solar panels. A solar inverter is the heart of any solar power system — it converts the DC electricity generated by your solar panels into AC power for household use.
In this solar inverter buying guide for beginners, we break down everything you need to know to make an informed decision, even if you’re just starting your solar journey.
What is a Solar Inverter?
A solar inverter is a device that transforms direct current (DC) from solar panels into alternating current (AC), which powers your home appliances. It also manages the system’s safety, monitors performance, and connects to the grid (in case of on-grid systems).
Types of Solar Inverters
1. On-Grid (Grid-Tied) Inverters
- No battery required
- Connects to utility grid
- Eligible for net metering
- Ideal for urban areas with reliable power supply
2. Off-Grid Inverters
- Works without grid
- Requires battery storage
- Suitable for remote or rural areas
3. Hybrid Inverters
- Combines grid and battery support
- Automatically switches between sources
- Great for areas with frequent power cuts
