Installation and use of solar energy controller

Wire preparation: it is recommended to use the stranded copper core insulation wire. To determine the length of the wire, the installation position of the case, as far as possible to reduce the wire length, in order to reduce the power loss. In accordance with the current density of not more than 4A/mm2 copper wire cross-sectional area, the controller side of the terminal strip 5mm insulation.

The terminal to connect the controller battery, and the other end is connected to the battery, note the +, -, not reverse connection. If the connection is correct, the indicating lamp (2) can be switched, press the button to check. Otherwise, should check the connection of it. Such as the occurrence of reverse connection, will not damage any part of fire insurance and controller. Just as the ultimate protection fuse controller itself internal circuit short-circuit damage.

Connect optical battery wires, wiring terminals to connect the controller on the battery, and the other end is connected to a photocell, attention +, -, not reverse connection, if the sunshine, the charge indicator lamp. Otherwise, should check the connection of it.
