Installer-approved advantages
-
3,000 W continuous / 6,000 W surge keeps essential loads running smoothly.
-
Wide PV window (60–115 V DC, 4,500 W max) lets you string up to 145 Voc without combiner loss.
-
High-current 80 A MPPT squeezes every watt from your array while safeguarding battery life.
-
48 V battery platform pairs effortlessly with today’s popular LiFePO₄ rack batteries or sealed lead-acid banks.
