PowMr 12V 24V 36V 48V 30A MPPT Solar charge controller lithium battery 


Advanced double-peak or multiple-peak tracking technology. When the panel has a shadow block or a part of the panel is damaged, I-V curve shows multiple peaks. The solar charge controller can still accurately track the maximum power point;

Built-in algorithm for maximum power tracking. This significantly raises energy utilization efficiency of photovoltaic systems, with charging efficiency 15% ~ 20% higher than traditional PWM solar charge controllers;

Combination of multiple tracking algorithms that can track the optimum working point of I-V curve accurately in a very short period of time;

MPPT tracking efficiency can be as high as 99.9%.Advanced digital power technology, with circuit energy conversion efficiency as high as 98%;

Supporting charging procedures of gel batteries, sealed batteries, open batteries, lithium batteries and other types of batteries;

Current-limiting charging mode. When the power of a solar panel is too large, and the charging current is greater than rated current, the solar charge controller automatically reduces charging power, thereby making the solar panel work at rated charging current;

LED indicator of malfunction, buzzer alarm, and liquid crystal display of abnormal information. This helps users identify system failures;

LCD screen display function. The display enables users to view equipment operation data and status, and modify controller parameters at the same time;

Temperature compensation functions. Charging and discharging parameters are automatically adjusted, thereby extending battery service life;

TVS lightning protection;


1. Brand:Powmr

2. Product model: ML4830N15

3. The solar charge controller can monitor generated power of solar panels in real time and track the highest voltage current value (VI), enabling the system to charge the battery with maximum power output;

4. The controller uses liquid crystal for the dynamic display of operation status, operating parameters, controller logs, historical parameters, and control parameters;

5. Users can check all parameters through buttons, and modify control parameters according to actual needs so that different system requirements are met;

6. The controller adopts standard Modbus communication protocol, making it easy for users to view and modify system parameters by themselves;

Installation and Wiring

Step 1: Selecting an installation location.

Avoid installing solar charge controller in a place where there is direct sunlight, high temperature or easy water inflow. Ensure the surrounding area of the solar charge controller is well ventilated.

Step 2: Place installation guide plate 

First place installation guide plate at proper position, then use pen and mark on installation location, drill four installation holes at marked places of suitable size, and fixe with screw.

Step 3: Fix the solar charge controller

On the installation surface, use a pen to mark the positions of four mounting holes, and then move away solar charge controller. Drill four size-suitable mounting holes at four marked positions, and fix screws in advance, align fixing holes of solar charge controller to on the four fixed screws, and then hang it up.
