Solar Inverter Technologies
Inverters convert the DC electricity generated by your solar panels into AC electricity for your home or business. Explore the different types and find the right match for your setup.
Types of Solar Inverters
On-grid Inverter
Designed for systems connected to the utility grid. These are the most common inverters and automatically shut down during a power outage for safety.
Hybrid Inverter
A versatile option that manages power from your solar panels, battery storage, and the utility grid simultaneously. Ideal for backup power setups.
Off-grid Inverter
Used in standalone systems not connected to the grid. They draw DC power from a battery bank and convert it to AC power.
String Inverter
Connects a 'string' of multiple solar panels to a single inverter. Highly cost-effective and commonly used in residential and commercial installations.
Microinverter
Installed on each individual solar panel. They maximize output by ensuring shading on one panel doesn't affect the performance of the rest.
How to Select an Inverter
1. Match the System Type
If you have a standard net-metered system without batteries, an on-grid inverter is all you need. If you plan to add batteries later or immediately, a hybrid inverter is the best choice to manage both solar and storage.
2. Consider Shading (String vs Micro)
If your roof gets a lot of sunlight without obstructions, a traditional string inverter is the most cost-effective solution. If you have complex roof angles or partial shading from trees, microinverters will yield higher energy generation.
3. Size it Correctly
Your inverter's capacity should match your solar panel array's output. A common industry practice is sizing the inverter at roughly 80-90% of the total DC panel capacity to account for real-world conditions (DC-to-AC ratio).
4. Check Warranties
Inverters typically have shorter lifespans than solar panels. Look for brands offering standard 5-to-10-year warranties, with options to extend up to 15 or 20 years for added peace of mind.
