1. 1KVA wall mounting type off-grid type solar inverter for off-grid solar power system
WS-series is off-grid type solar inverter that was built-in MPPT charger controller. So it is easy to make up complete solar power system when you connect it directly with solar panels, battery.
It also has two working mode. The first is solar PV working mode. When grid power is outage, please connect it directly with solar panels and battery. It will transfer solar DC power to AC power. The second is grid working mode. When utility power on, it will stabilize the input voltage and output pure sine wave AC power.
There is a chart of our products and some pictures for your reference
