The best solar inverters
Unlike the highly fragmented solar panel market, the market for solar inverters is much more consolidated. There are three different solar inverters that typically come out on top for residential solar panel systems: SolarEdge (string+power optimizers), Enphase (microinverters), SMA America (string inverters), and Tigo Energy (string inverters + module-level power electronics)
Choosing the best inverter for your home or business
Having trouble deciding between inverter options? Consider the following:
- Technology: are you looking for module-level inverters–like Enphase’s microinverters–or a central inverter with power optimizers, like what SolarEdge offers?
- Efficiency: how efficiently does the inverter convert the generated direct current (DC) to usable alternating current (AC) power?
- Warranty: does the manufacturer offer a comprehensive warranty for their product?
- Maximum output power: is the DC rating of your solar panel system similar to the output power of your inverters? This will help you avoid clipping.
- Storage compatibility: if you’re looking to install storage, is the inverter compatible with the battery you want to install?
- Monitoring app: what do you think of the monitoring app that goes along with your inverters? Does it provide you with the insights you’re looking for?
- Quality rating: how does the quality and durability of the inverter compare to other options on the market?
- Manufacturer reputation: does the company standing behind the warranty offer good customer service? Are they bankable?
- Cost: will you get your bank for your buck? Is a more expensive inverter actually worth the extra cost?
