SOL IA-S4 Series Off Grid Solar Inverter 3.5kW 3.5kVA 48V 51.2V220V & Stable Power Supply

Mobile scenarios such as RV camping and field operations have high requirements for the "autonomy" and "flexibility" of power supply. The Kaimin S4 off-grid solar inverter precisely meets these needs.

This device, with a rated output power of 3.5kW, can stably power mobile loads such as electric cookers, lighting equipment, and small tools; it also supports a direct operation mode without batteries, where solar panel power can directly supply power without waiting for battery charging, further enhancing the convenience of power usage in mobile scenarios.

In terms of energy configuration, the Kaimin S4 is compatible with both lithium-ion batteries and lead-acid batteries: lithium-ion batteries have a small size and high energy density, suitable for the space limitations of RVs; lead-acid batteries have a lower cost and are suitable for short-term outdoor operation scenarios. 

Its input voltage ranges from 48V to 51.2V, covering a wide range. The output is a standard 220V power supply for the market. It can directly match the common voltage specifications of mobile devices. Combined with the WiFi communication function, users can also monitor the power generation, power consumption and battery status in real time through mobile terminals, achieving remote management of the system. 

Whether it is the "comfortable power supply" for RV travel or the "stable power supply" for outdoor operations, the Kaimin S4 provides reliable power support for mobile scenarios.
