The Enphase IQ Battery 3T is an economical choice, especially designed for the NEM 3 California system. With kits available in both one and three batteries, it provides storage capacities of 3.3 and 10 kWhr respectively. Each 3T battery delivers a peak AC power of 1.92kW, and when three are combined, they offer a peak of 5.76 kW. While this might not be the best for backup power, it's an efficient solution for those looking to discharge battery power at night and charge with excess PV during the day. Additionally, the 3T system integrates seamlessly with the System Controller 2, which is equipped for genset integration. All of this comes with a dependable 10-year warranty.

Whether you're diving into the world of solar energy for the first time or looking to upgrade your existing setup, the IQ Battery 3T promises not just performance but also peace of mind.
