Off Grid Solar Inverter 1.2KW High frequency Wall Mounted LCD WIFI MPPT Solar Controller
Off Grid Solar Inverter 1.2KW High frequency Wall Mounted LCD WIFI MPPT Solar Controller
The Smart PY3 Series is a wall-mounted, high-frequency off-grid inverter that combines a pure sine wave inverter with an intelligent MPPT solar charge controller. Designed for residential and light commercial power setups, it supports a broad photovoltaic input range and can operate directly from solar panels when sunlight is sufficient, reducing or even eliminating the need for batteries in certain scenarios.
Leveraging advanced MPPT algorithms and smart BMS integration, the PY3 Series ensures precise energy management, superior battery protection, and maximum system efficiency. Its compact footprint, low standby power draw, and high conversion efficiency enable smooth, rapid transitions between solar, grid, and battery power sources, delivering consistent, high-quality electricity for homes, offices, and small-scale industrial applications.
