made to either one battery or a group of batteries in a
battery bank.

Multiple same models of controllers can be installed in
parallel on the same battery bank to achieve higher
charging current. Each controller must have its own
solar module(s).

Select the system cables according to 5A/mm 2 or less
current density in accordance with Article 690 of the
National Electrical Code, NFPA 70.
2.2 PV ARRAY REQUIREMENTS
(1) Serial connection (string) of PV modules.
As the core component of solar system, controller could
be suitable for various types of PV modules and maximize
converting solar energy into electrical energy. According
to the open circuit voltage (V
oc
) and the maximum power
point voltage (V
Mpp
) of the MPPT controller, the series
number of different types PV modules can be calculated.
