In order to improve the voltage drop and the system efficiency, if there is a longer cable
length between the PV module and the solar charge controller or between the solar charge
controller and the battery, a cable with a larger cross-section must be used.

Note that the negative terminals of the solar charge controller are connected to each other. If
grounding is required, always do so on the negative terminal cable.

Wiring and installation methods must comply with national and local electrical codes. The PV system
battery wiring specifications must be selected according to the rated currents.

However, if some devices with common positive poles are used in a common negative
system and the positive pole is grounded, the solar charge controller may be damaged.
