Connecting charge controller to battery.

How to connect solar panel to battery and charge controller.

Dc wire with gauges from 16 to 10 are typical for this. In the first step you are going to wire the battery to a charge controller. You can set the desired voltage on the charge controller depending on the capacity of the battery. 11 5v x 30 11 5 x 8 4 11 5 v x 21 9 a 251w assuming no losses.

The direct load can be directly powered up through solar power and a charge controller during the sunshine day time and during the shading night the dc load can be powered up using the battery. If you wire the solar panels to your charge controller first the fuse of the charge controller might blow. It also ensures that power does not go back towards. 11 5v x 8 4 a 96 6a.

Once the voltage has been stabilized by the charge controller it can now be channeled to the battery for storage. The solar power generated by the solar panel is received by the solar charge controller. If you connect a pwm solar charge controller to a battery bank at 11 5volts all you get from your solar panel is. Connect the wires from the controller to the solar panel.

A solar charge controller is a component that helps manage the power that is going into the battery store from the solar panel. Once you ve attached the input wires to the charge connector you should have 2 loose wires each ending in an mc4 connector. It is important to wire this component first before you wire the solar panels. Connect the outgoing leads from the panels to a charge controller.

The load terminal of the solar controller can be connected with a dc power device which is the same working voltage as the rated voltage of the battery and the controller supplies power to the load with the battery voltage connect the positive and negative poles of the load to the load terminals of the controller there may be voltage on the load side please be careful to avoid a short circuit when connecting the load a fuse should be connected to the positive or negative cord of the load. Match up the male and female connectors with the opposite ones coming away from the solar panel and snap the mc4 connectors into place. With an mppt solar charge controller however you get. If it is the usual 12 volt battery set the controller to 13 8volts.

A complete note on solar panel installation with calculation examples the dc load light fan etc is directly connected to the charge controller and can be fed up by two power sources. Calculate the wire size you need for this from a determination of the output current and the length of wire you need keeping in mind the charge controller should be located near the batteries.
