The Epsolar HP-3522W-AH1250P65A inverter is a high-frequency model with a pure sine wave output and an IP65 protection rating. It combines solar and grid or generator charging, while supporting grid bypass and energy management. The AC output supports parallel operation of multiple units, with configurations for single-phase or three-phase systems and the ability to expand system capacity up to 12 times.

It supports operation with or without a battery and is compatible with lithium, gel and sealed batteries. The BMS interface enables control of lithium battery charging and discharging, while RS485 communications and optional 4G and Wi-Fi modules support remote monitoring. Its MPPT technology has a maximum tracking efficiency of over 99.5%.
