Frequently Asked Questions

What is the difference between a string inverter, microinverter, and hybrid inverter?

String inverters connect multiple panels in series and convert DC to AC centrally — they're cost-effective for unshaded roofs. Microinverters (like Enphase IQ8) mount behind each panel for panel-level optimization and are ideal for complex roofs. Hybrid inverters (like Sol-Ark 15K) combine a string inverter with a battery charger, enabling energy storage. Our database includes 14 microinverters, 24 string inverters, and 31 hybrid inverters.

What is a good efficiency rating for a solar inverter?

Most modern solar inverters achieve 96%–99% peak efficiency. The average across our 69 inverter database is 97.6%. The most efficient model is the SolarEdge SE7600H-US at 99%. CEC (California Energy Commission) weighted efficiency is generally 0.5–1% lower than peak efficiency and reflects real-world performance more accurately.

How do I choose the right inverter size for my solar system?

Your inverter's AC output rating should typically match or slightly exceed your solar panel array's DC wattage. For example, a 6 kW panel array pairs well with a 6–7.6 kW inverter. Our database covers inverters from 0.3 kW to 20.0 kW. Oversizing the inverter by 10–20% helps account for efficiency losses and future panel additions.

Which solar inverter brands are the most reliable?

Among the 15 brands in our database, Enphase, SolarEdge, Fronius, and SMA are consistently rated for reliability and warranty support. Warranty periods range from 5 to 25 years. Microinverters (Enphase, Hoymiles) tend to have longer warranties (up to 25 years) compared to string inverters (10–15 years).

Do I need a hybrid inverter for battery storage?

Not necessarily. You can add battery storage using an AC-coupled battery system (like Tesla Powerwall or Enphase IQ Battery) with any standard inverter. However, hybrid inverters (31 models in our database) offer a single-box solution that's typically more efficient and cost-effective for new installations planning battery storage from day one.

What is MPPT and why does it matter for inverters?

MPPT (Maximum Power Point Tracking) optimizes the voltage and current from your solar panels to extract maximum energy. Inverters with more MPPT inputs (ranging from 1 to 6 in our database) allow panels on different roof faces or with different shading conditions to operate independently at peak efficiency. Most residential systems need 1–2 MPPTs.
