Product Description

12V/24V Auto Identified MPPT Solar Controller 30A

Description:
The full name of the MPPT is maximum power point tracking. It is an advanced charging way which could detect the realtime power of the solar panel and the maximum point of the I-V curve that make the highest battery charging efficiency. 

Feature:
1,Adopting double crest or multi crest tracing technique, used for the condition when a part of solar panel is under shadow or parts of solar panel is damage.

2,Builtin maximum power point tracking algorithm which could promote the energy utilization efficiency of pv system. The charging efficiency is 15%~20% higher than PWM mode.

3,It can find out the best working point of  IV curve within 1 minute. the MPPT efficiency could reach to 99.9%.

4,Adopting advanced digital power supply techniques which makes the energy conversion efficiency reach up to 97%.

5,Four charging stages: MPPT - equalizing charge- boosting charge- floating charge.
6,With current limiting charging mode. When the power of solar panel is oversized, the controller will lower charging power automatically, which enable the system to work under the rated charging current. 

7,Have the fault code indication, it helps user confirm the system fault.

8,Various load control methods. Could recognize day and night automatically.

9,Various system protection functions. Including over-charge, over-discharge, over-load, over-heat, battery-reverse connection and short-circuit protection etc.

Using Suggestion

1.The solar panel's terminal voltage may exceed human safety voltage, please use insulating tools and ensure the hands dry.  

2.Please connect wires cautiously and correctly. Although controller has reverse protection and short circuit protection, that doesn't mean it could handle all kinds of wrong, reverse connection and short circuit.

3.Please don't connect the solar panel to the controller's battery port or load port, otherwise the high voltage of the solar panel will damage the controller.

4.Please connect the battery first, then connect other equipments after the battery indicator on the controller is normally on. If connect battery reversely, the voltage of the load port will be the minus value of the battery voltage. That may damage the load equipment.

5.MPPT controller is designed according to solar panel's I-V curve, so when the controller connect the general constant voltage DC source, the controller may not work.

6.Advice is installing in the ventilated and well-cooled environment, because the controller will fever during operation.

7.Choosing the proper cable with enough capacity to avoid extra power loss in the circuit. Too much circuit loss may lead to wrong judgment.

8.Full charge is very important for the battery. The battery should be full charged at least once a month otherwise the battery will suffer permanent damage. The battery can be full charged only when the input power of the battery is more than power consumption of the load.

9.Please do not dip the controller into the corrosive liquid otherwise the controller will be damaged and release harmful gas.

10.Because the battery stores lots of energy, do not allow the battery short circuit in any case. We suggest tandem connect a fuse on the battery

11.The battery may release combustible gas, please far away from the spark.

12.Ensure the children are far away from battery ,pv and controller
