PV configuration 
Maximum open circuit PV voltage:100V.
The controller can be used with any PV configuration that satisfies the three above mentioned conditions.
 
For example:
12V battery and mono-or polycrystalline panels
•Minimum number of cells in series :36(12V panel).
•Recommended number of cells for highest controller efficiency:72 (2 x 12V panel in series or 1 x 24V).
•Maximum:144 cells (4 x 12V or 2 x 24V panel in series).
24V battery and mono-or polycrystalline panels
• Minimum number of cells in series :72 (2 x 12V panel in series or 1 x 24V panel).
•Maximum:144 cells.
Remark: at low temperature the open circuit voltage of a 144 cell solar array may exceed 100V, depending on local conditions and cell specifications. In that case the number of cells in series must be reduced.
Hanfong as the main solar controller suppliers and solar inverter manufacturers in Guangzhou provide high quality power inverter and solar controller for Europe and middle east market.
