40A Mppt Solar Charge Controller Dual Usb Lcd Display Auto

As the most high-end and advanced solar charge controller, it charges the battery with the max , MPPT tracking efficiency is 99%, and the whole system has a high generation efficiency of 97%.



Features:

This product provides short-circuit protection,open-circuit protection, reverse protection, overload protection.

Automatic focusing MPPT tracking , high efficiency, non-stop detection during , bidirectional focusing tracking.

MPPT solar controller can detect the voltage and current of the solar panel in real time, and constantly track the maximum , so that the system can always charge the battery with the maximum .

The tracking efficiency of MPPT is 99%, and the generation efficiency of the whole system is up to 97%. 

Moreover, the system has excellent battery management, including MPPT , constant voltage average and constant voltage float .

Notes:

1.What is MPPT? 

Automatic load tracking aggregation. 

2.Why "Only works with the battery connected, turn on the solar panel charges the battery, charge does not work"? Why is it less than 100A?

We are a current-focus MPPT with two constantan wires designed to detect current and maximum open-load when more 1A.This technology is our patent practice, and has been recognized by the state, with a special patent certificate of invention.There is no such technology on the market. 

Compared with other MPPT MPPT-inductive buck-boost type, the same solar condition, our current-focusing MPPT current tracking efficiency is higher, because of the loss caused by the booster and the step by step down.

In fact, the effectiveness of very low light is very low because the input is very small. And our MPPT can also increase the load under relatively low illumination. Our MPPT is straight-through type. When the current is greater than 1A, it will not be tested. The chain will be charged directly. Only when it is charged to 95% of the battery, will it slow down and protect the battery.
