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

Features:
This product provides short-circuit protection,open-circuit protection, reverse protection, overload protection.
Automatic focusing MPPT tracking charging, high charging efficiency, non-stop detection during charging, bidirectional focusing tracking.
MPPT solar controller can detect the voltage and current of the solar panel in real time, and constantly track the maximum power, so that the system can always charge the battery with the maximum power.
The tracking efficiency of MPPT is 99%, and the power generation efficiency of the whole system is up to 97%. 
Moreover, the system has excellent battery management, including MPPT charging, constant voltage average charging and constant voltage float charging.

Specifications:
Battery voltage: 12V/24V Auto Adapt
Material: ROHS+ABS
Item color: blue+black
Charge current: 30A, 40A, 50A, 60A, 100A (optional)

Package weight: 295 g / 10.41 ounce

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 charging condition, our current-focusing MPPT current tracking efficiency is higher, because of the power loss caused by the booster and the step by step down.
In fact, the effectiveness of very low light charging is very low because the input power 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.

    Seems to be working OK very well-built the only thing it didn’t come with was connectors to come out of the solar panel so I got my wire cutters and just cut them off and tied it in direct working great

    My partner is sensitive to leds' that flicker at a rate anywhere near the visible. With all the pwm controllers this was a constant problem that got worse with dimming. These problems are gone with this MPPT controller!!! This alone made it worth twice what I paid, the fact it harvests more electricity than any of its competitors (that I personally used) makes it even better. Give this one a try!

    So far after a week, this is working great for me. 40 amp rating is probably and overkill for what I currently need but good to know i have enough amperage capacity ahould I need more. I hoopked it up with a 50 watt solar panel and LED bulbs for my landscape lighting.

    I use this set up for power in very remote locations to power my cell phone and laptop so that I can still provide fabrication services to people out side of civilization and off-grid. It's not super power-hungry and this set up lets me keep working!

    Great charge controller for the price! 30 amp at harbor freight 74.99 vs 50 amp for 25. Currently have a 100 watt panel set up, but am going to add more in the future. Works great for what I needed it for.

    This little Charge Controller is perfect for the one module setup I've made to keep my tractor battery charged up between uses. Other than that its pretty good charge controller.
