SAJ 5kW Hybrid Solar Inverter

175,000.00 165,000.00

Sunfree 4K/5K Energy Storage Inverter

Sunfree 4K/5K energy storage inverters are used in residential PV energy storage systems, with peak-cutting and valley-filling functions to maximize the use of PV power generation while achieving the goal of saving residential electricity bills. In addition, different working modes can be set as per different customer needs. They are compatible with lead-acid batteries and lithium batteries and can provide uninterrupted power for important load devices with a back-up power supply.
