The inverter supports a recommended maximum PV input power of 9,000 Wp, with a maximum input voltage of 1100 V and two MPP trackers. Its battery input operates within a voltage range of 600 V to 980 V and can handle a maximum current of 16 A.
[pdf] Input voltage indicates the DC voltage required to operate the inverter. Inverters generally have an input voltage of 12V, 24V, or 48V. The inverter selected must match the power source, such as batteries or solar panels. Solar and EV systems usually use higher input voltages, such as 48V or more.
[pdf] One of the most significant ways input voltage affects a power inverter is efficiency. Every inverter has an optimal input voltage range where it operates most efficiently. If the input voltage is too low, the inverter has to work harder to convert the DC power to AC power.
