Introducing our multifunctional off-grid solar inverter: an all-in-one device integrating a MPPT solar charge controller, a high-frequency pure sine wave inverter, and a UPS function module. This inverter is ideal for off-grid backup power and self-consumption applications, capable of operating with or without batteries.

For a complete and operational system, additional devices such as PV modules, a generator, or utility grid are required. Consult with a system integrator for various system architectures tailored to your needs. The optional plug-and-play WiFi/GPRS module allows users to monitor their PV system's status anytime, anywhere, via a mobile phone or website.
