Free shipping!!! DC 72V Intelligent PWM Solar Charge Controller 72v10a/20a Solar Panel Regulator for Electric vehicle lead acid battery  

Controller is only applicable to the system which is solar energy with 72V rating voltage. Battery is in plumbic acid with liquid openings or be sealed (by VRLA valve) and can also be ferrous phosphoric acid lithium. Note the type before you buy it.

Function:

1. 72V Automatic identification by system

2. LED digital display and one-key operation, easy to use

3. The improved 3-section computing method can weekly give the battery a balanced charging. It can stop the battery from being unbalancing and vulcanizing and let the battery been used for more time. 

4. the controller is equipped with the serial PWM charging main circuit with additional 3%~6% efficiency than the non-PWM circuit which can work for more time and increase the using period of the system.  

5. Controller has three load work ways and can be easily used in varies streetlights and monitors.

6. Visualized LED display which can let the users get to know the conditions of solar power and storage battery.

7. Overcharge, over discharge and overload protection; Electronic short circuit protection; Reverse connect preventing protection.

8. Lightning prevention.
