MPPT Solar charge controller 40Amp, MPPT solar regulator, both off grid& grid connected, PWM
Intelligent MPPT solar charger controller, with BTS(battery temperature sensor), 12v/24vdc 40A, can be parallel, in stock.
Key features:
High converting efficiency higher than 97% for minimizing energy loss
Build-in MPPT tracker for opeimizing the power transformation
Reversed current protection for preventing equipment damage
Automatic battery temperature compensation for long term reliability
Capable of selecting different charging mode for various type of batteries
Capable of connecting additional DC load for wider applications
Three stage charge control system(bulk, absorption, and float mode) with temperature compensation
LED indicators display charge status in real time
Pulse width modulation(PWM) topology combined with a multi-stage charge control algorithm leads to superior charging and enhanced battery performance.
