Easun Off Grid Inverter 11KW 48V MPPT Dual Input WiFi BMS

Easun Off Grid Inverter 11KW 48V MPPT Dual Input WiFi BMS delivers reliable off‑grid power with intelligent solar charging and seamless grid integration. Designed for homes, cabins, workshops, and remote setups, this 11 kW pure sine wave inverter provides clean, stable AC power from a 48V battery bank or directly from solar, helping you stay powered when the grid is unreliable or unavailable.

Key to its performance is the built‑in dual MPPT solarControllers and a configurable input/output workflow that lets you prioritize solar or grid charging for your specific needs. With LCD configuration, you can tailor the device to protect sensitive loads such as personal computers, and optimize battery charging for longer life. The inverter supports mains or generator power, auto restart after AC recovery, and a smart battery charger design that enhances battery longevity. It also includes a cold start function for reliable startup in low‑temperature environments.

With WiFi and RS485/RS232 communication, you can monitor and manage performance remotely, while the unit’s protections—overload, over‑temperature, and short‑circuit—keep your system safe. Parallel operation enables scaling up to 6 units for higher power demands. This model supports Lithium battery activation and communication for advanced battery management, and it is built to work with a wide range of equipment thanks to automatic sensing of 50/60 Hz.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty. At intercyprus.com since 2002 — trusted for quality and reliability.
