Maximum PV Module Open Circuit Voltage
(Never over max PV Voc)
For 12V Battery: 80V; For 24V battery: 105V;
For 36V battery: 160V; For 48V battery: 160V.
Notes: Voc of PV should be in the correct range and when it’s 1.5 or 2 times than battery voltage,
then it’s best efficiency. Please choose the PV modules with right Voc.
