Deye Hybrid Three Phase Inverter SUN-12K-SG04LP3-EU
Product Description
The inverter is suitable for residential use, maximizing the self-consumption rate of solar energy and increasing energy impedance. During the day, the PV system generates electricity that will initially be supplied to loads. The excess energy will then charge the battery or be delivered to the grid. The inverter meets the standard EN50549-1, which means it can be successfully used to become prosumer. The battery can also be charged by the diesel generator to ensure uninterrupted power supply in the event of a grid outage. It is equipped with RS485/CAN port for battery communication.
