2.2 Basic Settings
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.
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.
