Overview

PowerMax 314 Outdoor Overview

Inside, 314Ah of LiFePO4 cells deliver 7.68kW of rated DC power with 150A standard and 190A maximum charge/discharge current. The built-in BMS monitors state of charge, current and temperature and protects against overcharge, over-discharge and overheating, while a front touch screen and Wi-Fi/Bluetooth app show everything in real time. The battery is UL1973 and UL9540A certified and CEC listed - the certifications utilities and inspectors ask for.

CAN/RS485 communication makes the PowerMax compatible with SunGoldPower, Sol-Ark, Victron, Growatt, EG4, Schneider, Luxpower, Deye, MPP Solar, Megarevo and other inverters.
