About This

EASY MONITOR: Pairing the solar controller with your phone via ChargePro 2.0, which makes seeing output and history data a breeze, also allows the charge voltage, current, etc. to be set for different type batteries. The remote app control provides 15 feet signal.
TRIPLE COOLING DESIGNED: Die-cast aluminum case, internal glue filling, glass panel design, better heat dissipation performance, to ensure that the controller maintains a long time full current output. Heavy duty designed also allows solar charge controller to keep efficient work.
ACTIVE SHIELD: With 6 protections, over-temperature, open-circuit, short-circuit, overload, polarity reverse prevention circuit, flow backwards of current protections. MPPT solar charge controller features with dual MOS circuit to prevent the reverse current and to reduce the heat in operation. Maintain your battery all the time. With the heavy-duty heat sink on the back sheet, it can increase thermal effectiveness of the solar charge controller.
EFFICIENT: Using the latest, fastest MPPT technology, 40A MPPT solar controller provides up to 99% conversion rate. With temperature sensor, it is able to support lead-acid battery temperature compensation. Feature negative ground design, the 40amp MPPT solar panel regulator can compatible with most RV or other vehicle system.
