eTracer-AD is an intelligent, efficient, high-speed solar charge controller with advanced Maximum Power Point Tracking (MPPT) algorithm, which can harvest the maximum power from the solar array to charge battery. It can be applied in the off-grid PV systems up to 3KW, and increase the efficiency up to 30% .
The die-cast aluminum design ensure higher heat dissipation performance. Electronic protections prevent damage as operating error.RS485 Port/Modbus protocol improve extensive communication ability, and programmable parameter make the controllers working with different battery types.
