EARNMee 120A MPPT solar charge controller ⚡
Product description
This MPPT solar charge controller is built for high-power off-grid systems and larger battery banks, offering up to 120 amps of charging current and PV input voltage up to 230V to handle extensive solar arrays. If you need reliable charging for mixed battery technologies, this 120A MPPT solar charge controller brings wide voltage compatibility and automatic system voltage detection to simplify setup and operation.
Key Points
The controller supports a broad range of battery voltages from 12V up to 96V, which allows it to be used with different battery configurations across residential and commercial installations. It accepts multiple battery chemistries including sealed lead acid, gel, and lithium variants like LiFePO4 and standard Li-ion, helping cover various stages of battery systems. The unit includes protections against overcharge, overcurrent, overheating, and short circuits, and it has a lithium battery activation function to attempt recovery of low-activity lithium cells. ⚡️
This model also features full power input handling, which means it is intended to maintain consistent power delivery under higher demand situations. Consider that such wide capability may require appropriate system wiring and a compatible inverter or load to match the controller’s capacity. 🔧

Usage Recommendations
Install the controller where it has adequate ventilation to reduce the chance of thermal shutdown during prolonged high-power operation. For systems using lithium chemistry, use the controller’s configurable charging profiles and the lithium activation feature as appropriate according to the battery manufacturer’s specifications. When pairing with an inverter, match voltage ranges carefully and confirm that the inverter input is compatible with the chosen battery bank arrangement.
If you expect to run near the upper PV power limits, plan for proper cabling and overcurrent protection on DC connections to maintain safety and reduce voltage drop. According to the manufacturer, the device undergoes quality checks before shipment and the package includes the controller and a user manual for setup and troubleshooting.
