Hybrid Inverter 3.6KW Off Grid Solar Inverter Wall Mounted LCD WIFI MPPT Solar Controller

Hybrid Inverter 3.6KW Off Grid Solar Inverter Wall Mounted LCD WIFI MPPT Solar Controller

The Smart PY3 Series is a wall-mounted, high-frequency off-grid inverter that integrates a pure sine wave inverter core with an intelligent MPPT solar charge controller. Developed for home and light commercial power systems, it accepts a wide photovoltaic input range and is capable of running directly on solar power when irradiance is sufficient, eliminating the need for batteries under certain conditions.

Through advanced MPPT control and smart BMS coordination, the PY3 Series delivers precise energy tracking, enhanced battery protection, and optimized system efficiency. Its compact design, reduced standby consumption, and high conversion performance allow for fast, stable transitions between solar, grid, and battery sources, providing reliable, high-quality power for residential, office, and small industrial applications.
