Product Description
S6-EH3P(3-10)K-H-EU
Solis S6-EH3P(3-12)K-H Three Phase Hybrid Solar Inverter is an advanced energy storage solution designed to maximise solar energy utilisation for residential and small commercial applications. By integrating solar PV generation, high-voltage battery storage, and intelligent energy management, this hybrid inverter enables efficient power conversion and reliable energy supply.
During the day, the inverter prioritises solar energy to power household loads while storing excess energy in a connected high-voltage battery. At night or during periods of low solar generation, stored energy is automatically discharged to supply home appliances, reduci
ng dependence on grid electricity and improving energy independence.
With flexible operating modes, high efficiency, and seamless integration with modern energy storage systems, the Solis S6 hybrid inverter helps users optimise self-consumption, lower electricity costs, and achieve a more sustainable energy solution.
