The EPever Tracer 3906BP is a 15A IoT-ready MPPT solar charge controller engineered to extract maximum energy from your solar panels — delivering up to 30% greater charging efficiency than conventional PWM controllers. Its advanced Maximum Power Point Tracking algorithm continuously scans and locks onto the peak power point of your solar array, converting up to 200W at 12V (or 400W at 24V) of PV input into precise, stage-optimised charging current for your battery bank. Compatible with sealed, gel, flooded, LiFePO4, and Li-NiCoMn batteries, the Tracer 3906BP automatically identifies 12V or 24V system voltage and applies the correct charge profile from the moment it is connected.

Built for Australian caravanners, 4WD tourers, and off-grid campers who depend on solar power in the field, the Tracer 3906BP handles everything from a rooftop panel on a caravan or camper trailer through to a dedicated off-grid cabin or remote campsite power setup. Its RS485 MODBUS communication port pairs with the optional MT50 remote display, Bluetooth adapter, or Wi-Fi module so you can monitor state of charge, PV input voltage, and charge status from your phone — essential when the controller is mounted inside a 4WD canopy or caravan battery bay. EN, EMC, and RoHS certified, this controller is a dependable, future-proof choice for any serious solar setup on Australian roads and tracks.
