Cheapest solar charge controller

Cheap solar charge controller 10A 12v / 24VCheapest solar charge controller for your small solar system only for $10.

This solar charger can automatically manage the working voltage of the solar panel and the battery of your solar system. Make sure the rated voltage of the solar panel (pin 1,2), batteries (pin 3,4) and the loads (pin 5,6) are same, and are all 12v or all 24v.

The rated current of the solar panels and the load (pin 5,6) must be less than the rated current of the solar controller (10 Amperes).


 - over-load protection

 - short circuit protection

 - under voltage protectecion for your battery

 - over-charging protection for longer battery life

 - protection from the lightning strike

 - reverse-polarity protection (+,-)

 - suitable for small solar energy systems

 Cheapest solar charge controller under 10$


Open the top of the controller, connect the wires to the terminals of the solar controller according to the diagram on the top of the controller or to the user manual (page2). First connect the "+" and "-" poles of the battery to the 3 and 4 terminals.. If the load indicator (Load LED) flickers once and starts lighting after 30 seconds the battery was correctly connected.

 LED indicators:

The battery is being charged strongly when the "charge LED" is lighting, if it's off means charging stopped; flickering means the battery is in floating charge mode.

When the "load LED" is lighting it means there is output and load can work; if it's off, there isn't output voltage.
