Primax Venus 4200 Off-Grid MPPT Solar Inverter
Model VENUS-4200
Primax Venus 4200 is a 4200 W single phase pure sine wave MPPT solar inverter that runs on or off grid, with or without a battery. It accepts up to 6200 W of PV on a 60-450 VDC MPPT window, charges at up to 120 A from solar, and reaches 98% maximum conversion efficiency. Dual output separates a full-power main load from a 1400 W secondary load in battery mode, with built-in lithium battery activation, an anti-dust kit for harsh environments, RGB lights and an LCD display.
