Product description

EARNMee controller is used in solar off-grid power generation systems to automatically regulate battery charging and discharging. It has an advanced tracking algorithm to obtain the maximum power of the solar module to charge the battery; at the same time, its Low Voltage Disconnect (LVD) function prevents the battery from over-discharging and causing damage.The MPPT controller’s comprehensive self-test function and electronic protection function can avoid damage caused by installation errors and system failures.

Basic Function:

Innovative maximum power point tracking technology, can significantly improve the solar energy system energy utilization, conversion efficiency up to 97%;

Rapidly scanning the entire IーV curve, efficiently tracking the maximum power point;Sealed, gel, open three types of lead-acid batteries and lithium batteries series of charging programs can be selected;

With overcharge, overdischarge, overload, short circuit automatic protection function;RS485 communication interface, can be multi-computer communication, convenient to view the controller’s operating parameters.

Six advantages of choosing us: 1、Self-contained lithium battery activation function 2、Support 0-230V ultra-wide voltage access 3、12-96V battery universal 4、With a large screen display 5、Can be charged even in cloudy and rainy days 6、Parameters can be adjusted

Side panel description

note：Controller adjustment must be matched with the battery type, solar panel maximum voltage input 230V, battery and inverter input volts should be the same.

Our MPPT supports custom charging methods, allowing users to set their own charging voltage, float charging voltage, charging current, and more.

Steps for setting output current/voltage: Set up – Battery Type Settings – Custom

attery type – lead-acid batteries：Automatic recognition for 12V/24V/36V/48V/60V/72V/84V/96V

Battery type-lithium batteries：Manual setting for 12V/24V/48V/60V/72V/84V/96V

12V MPPT solar controller：Applicable to low-power scenarios like solar street lights, garden lights, small household power systems, communication base stations. Advantages: Low voltage for high safety, simple circuit, favorable price, and compatible solar panels/batteries are common and easy to replace.

24V MPPT solar controller：Used in off-grid systems with slightly higher power demands (RVs, ships, small PV plants) and for powering multiple 12V devices (e.g., small monitoring systems). Advantages: Smaller current, lower line loss at same power, supports higher-power loads, high efficiency, and compatible with 12V devices (via series connection/step-down modules).

48V MPPT solar controller：Suitable for small-to-medium commercial solar systems (power for small malls/offices) and off-grid industrial equipment (power for some devices in small factories). Advantages: Supports high-power solar panels/loads for large off-grid systems, smaller current, lower line loss, suitable for long-distance transmission, and high overall efficiency.

96V and above high voltage MPPT solar controller：

Applicable scenarios: Mainly used for large-scale solar power generation and energy storage projects such as large-scale photovoltaic power stations, photovoltaic energy storage systems, and smart microgrids.

Advantages: It can connect more solar panels to form a larger scale power generation system, improving overall power generation efficiency and power output; It has obvious advantages in long-distance transmission and large-scale energy storage, which can reduce transmission costs and improve system stability.
