PowMr MPPT 60A 50A 40A 30A Solar Charge and Discharge Controller 12V 24V 36V 48VAuto for Max PV 190VDC Lead Acid Lithium Battery

This is PowMr 100% original MPPT Solar Controller, please do not listen to the false information from our competitors,they just want to spread the misleading information to increase their sales , this is inglorious !

now we offer the cheaper and cheaper price to help our customers ,We must continuously struggle! never never give up !  


Why we sell so cheapest price on Aliexpress?

Yes ,do not be worried ,Recently ,our competitors misguide consumers by spreading false information ,they just want to make more money from customers ,now we decide to reduce our profit to sell better price to help our customers !

Our products are all for independent research and development production, all of the direct manufacturers, same quality in our lowest price!


The low quality MPPT is V117 V118 , they say our MPPT is V113 , that is funny ,our solar controller and their solar controllers are from different factories,what is the meaning comparing the solar controller Versions from two different factories,and different brands?  please do not ignore the parts quality inside !

The Version of MPPT Solar Controller is PowMr 2019 !



100% MPPT controller

Intelligent Maximum Power Point Tracking technology

Built-in DSP controller with high performance

Automatic battery voltage detection 12V/24V/36V/48V

Three-stage charging optimizes battery performance

Multi-function LCD displays

Reverse polarity protection of solar panel

Overcharge protection

Can be mounted easily

Suitable for battery types of sealed lead acid, vented Gel, and Lithium battery

Notes: The output terminal is for lamp only ( 12V system less 60W, 24V/36V/48V system less 100W ),and it will be burnt if connecting to other loads. The output for battery is no polarity reverse protection. 


you can Put two pieces 40A in parallel , So total is MPPT 80A

               Put two pieces 50A in parallel ,So total is MPPT 100A

               Put two pieces 60A in parallel ,So total is MPPT 120A
