EARNMee 60A MPPT Solar Charge Controller for 12–96V Systems, 230V VOC Input, RS485

The EARNMee 60A MPPT Solar Charge Controller is a high-capacity, wide-voltage regulator that manages PV arrays and charges batteries from 12V up to 96V with MPPT efficiency and VOC up to 230V.

This controller is built for systems that need a single device to handle many battery voltages and larger PV inputs. It automatically senses system voltage and optimizes solar harvest with MPPT logic while offering multiple protections and communication options for monitoring. The unit ships with a user manual, undergoes quality checks before dispatch, and includes a 12-month maintenance promise.

How does this controller adapt to different battery voltages?

The controller automatically detects the connected battery voltage and configures charging parameters accordingly, covering 12V through 96V systems. That flexibility removes the need for different models when upgrading or switching battery banks.

• Auto-identifies system voltage from 12V to 96V
• Supports lithium-ion, LiFePO4, GEL and other lead-acid types
• Single device fits multiple system designs and upgrades

What maximum PV and input limits should I plan for?

PV input capacity scales with battery voltage to keep charging within safe limits; the controller accepts a VOC up to 230V. Refer to the listed PV maxima per battery voltage when sizing your array to avoid overloading the controller.

• 12V battery: PV max 720W
• 24V battery: PV max 1440W; 36V: 2160W; 48V: 2880W
• 60V–96V battery ranges up to PV max 5760W depending on nominal voltage

What protections and battery care features are included?

The controller integrates multiple safety circuits to protect equipment and batteries from common electrical faults. It also has a lithium battery activation routine to revive low-activity lithium cells and help extend usable battery life when safely possible.

• Overcharge, overcurrent, short-circuit and overheating protection
• Low-activity lithium activation to restore charge acceptance
• Stable full-power input mode for demanding loads

Can I monitor the controller remotely or integrate it into larger systems?

Yes — the controller includes an RJ12 port for RS485 communications, enabling data retrieval and integration via MODBUS where supported. Wiring is labeled A-B for straightforward connection, though you should confirm pinout if you encounter reversed print labels.

• RJ12 interface for RS485 communication and data polling
• Labelled A-B wiring; contact seller for MODBUS commands or custom setup
• Useful for system monitoring, logging, and integration with controllers or HMIs

Who is this for: The EARNMee 60A MPPT is aimed at installers, hobbyists, and small-to-medium off-grid or backup power users who need a single MPPT controller to handle varied battery voltages and larger PV arrays. It suits systems that require robust protection features, remote monitoring capability, and the flexibility to change or expand battery banks without replacing the charge controller.
