Solis Smart Energy Storage Inverter for Solar Power Systems

Product Description

Product Description

S6-EH3P(12-20)K-H series three-phase energy storage inverter, suitable for large residential and small commercial PV energy storage systems. This series of products support generator networking and parallel operation of multiple inverters; 4 MPPT design, is perfect for large rooftop PV energy storage systems with more roof orientation and complex structure. Products with multiple flexible load capacity, including UPS level switching; 10second 200% surge power backup overload capability, and adapt to three-phase unbalanced load,half-wave load, more friendly and reliable power supply for the load.
