MPPT solar charge controller for RV

Driving a Recreational vehicle to go out and travel is new kind of recreation. For a long time outside, lack of power is not convenient, is a common problem we all encounter. Installing solar panels on the roof of a RV, with a backup battery, charging the two batteries through the solar RV controller, will provide some basic emergency power needs. Now I will introduce a new O developed MPPT solar RV controller.

A: Function introduction

1, increase the charging current, compared to the traditional PWM controller, MPPT charging efficiency can be increased by 10-30%. (Controller conversion efficiency> 95%)

2 can be selected by DIP switch 4 batteries. GEL batteries, lead-acid batteries, AGM2 batteries, lithium iron phosphate batteries.

3. Two charging interface, you can automatically charge the main battery of solar energy equipment. You can also charge the starting battery of the RV, with over-voltage protection

4. Automatic unattended charging. With overload, overheating, reverse current protection (cloudy or no sunlight at night, to prevent the battery back to the solar panel)

5. Overcharge protection. When the battery is full, the charging current will be reduced, when the battery is dead, it will immediately charge the battery

6. Automatic temperature compensation. Ensure that the battery in the low temperature or high temperature environment, the use of the best power supply parameters to extend the battery life It is strongly recommended, do not install the battery and controller in the heat source place, so as to avoid controller error.

B: safet by norms and use

1. Only charge GEL batteries, lead-acid batteries, AGM batteries and lithium iron phosphate (MBS batteries) that meet the rated voltage.

2. Use solar panel power controller, if the cable is too small, it will lead to overheating of the cable and energy loss.

3. Install a rated-size fuse near the battery terminal to protect the battery between the battery and the solar panel.

4 .. Please install in a well-ventilated room to prevent rain, moisture, dust, aggressive battery gas and no condensation in the environment.

5. When the machine is sold, does not deserve any accessories. If you need to change parts, please contact the supplier

6. Keep the controller and battery away from children.

C: battery life instructions

1, the battery dissatisfied with the situation please promptly to those who lack of battery charge battery, especially some old batteries, or use the battery in hot places. Otherwise it will affect the battery life Please select the appropriate installation location to ensure that the battery dry and ventilated environment.

2, the controller uses 12V battery, in order to prevent damage to the controller, when the battery voltage is about 15-16V, the controller stops working.

3, charging over-voltage protection When the battery voltage in any mode when charging more than 15V, will stop charging.

4, the controller overload thermal protection When the controller charging temperature is too high, or the ambient temperature is too hot, the controller into protection mode, stop charging.

5, Voltage measurement Because of the reason of line loss, if you want to measure the voltage of the battery, you must measure the two sections of the battery directly instead of connecting the terminals of the battery to the controller.
