Setting the Fixed Voltage Level
Your Sunways Solar Inverter is equipped with a precise MPP control. If less than 200 watt are injected, the control of the energy unit concerned operates at a fixed voltage level. That prevents unnecessary MPP searching. To minimise adjustment losses during fixed voltage operation, the fixed voltage level of each energy unit of the Solar Inverter can be set separately. The optimum fixed voltage level depends on your PV generator model.

Illustr.: Slide switch «S100» for setting the fixed voltage level
The fixed voltage can be set with the slide switch «S100» on the control circuit board. Ex works, the switch is set to «420V».
To set a fixed voltage of 540 V, slide the switch to the «540V» position.
