Off Grid Solar Inverter 3.5kW 3.5kVA 48V 51.2V220V & Integrated MPPT Charge Controller & BMS Communication Functions

For off-grid power systems that require high performance, the Kaimin S4 inverter, with its multiple core technical advantages, becomes the ideal choice for professional scenarios.

The built-in MPPT controller can continuously track the maximum power point of the solar panels, and its power generation efficiency is at the industry-leading level, enabling full exploitation of the energy potential of photovoltaic resources. 

In terms of system scalability, the Kaimin S4 supports the parallel operation of 9 devices, and the system power can be expanded to 31.5kW, which can meet the high-power requirements of small and medium-sized industrial scenarios.

In terms of battery management, this device is not only compatible with lithium-ion and lead-acid batteries, but also integrates BMS communication functions, which can monitor the battery health status in real time and effectively extend the battery service life. 

In addition, its input voltage ranges from 48V to 51.2V, covering a wide range. The output is a 220V pure sine wave mains power supply, and the voltage stability meets the power supply standards for precision equipment. At the same time, it supports a battery-free direct operation mode, and can be directly powered by a solar panel, suitable for emergency power supply needs in unexpected situations. 

With technological advantages at its core, the Kaimin S4 inverter is the key equipment for building professional off-grid power systems.
