Inverters

SunPower high-efficiency inverters are designed specifically to support our high-performance solar panels.

SunPower residential systems include our own lines of inverters that turn DC electricity from our panels into utility grade AC power. SunPower inverters provide superior performance to maximize the energy output of our solar electric systems.

Their optimized design ensures our customers capture the maximum amount of solar energy each day of the year.

All SunPower high-efficiency inverters come with a 10-year standard equipment warranty.

Grounding
SunPower high-efficiency systems must be installed with proper grounding and inverter configuration procedures in order to perform optimally to their specifications. This is to ensure SunPower panels only see negative voltage as referenced to ground.

For optimal performance in North American installations, SunPower solar panels should be used with SunPower positive ground inverters where the positive polarity of the array is connected to ground. The SunPower inverters listed above meet this requirement.

For optimal performance outside the United States, SunPower panels must only be used with transformer-based inverters where the positive (+) polarity of the array is connected to ground.
