Wholesale Solar offers all types of charge controllers from OutBack Power, Schneider Electric(formerly Xantrex), Morningstar, Blue Sky Energy, and, now, Midnite Solar's revolutionary Classic MPPT charge controller.
The main function of a charge controller or regulator is to protect your battery from overcharge and block a reverse current. If a non-self-regulating solar array is connected to lead acid batteries with no overcharge protection, the life of your batteries will be compromised.
Simple controllers contain a transistor that shunt the PV charging circuit, terminating the charge at a pre-set high voltage and, once a pre-set reconnect is reached, opens the shunt, allowing charging to resume.
More sophisticated controllers utilize pulse width modulation (PWM) or maximum power point tracking (MPPT) to assure the battery is being fully
charged.The first 70% to 80% of battery capacity is easily
replaced, but the last 20% to 30% requires more attention and therefore more complexity.
MidNite Solar Classic Charge Controllers
Midnite's Classic offers 150, 200 or 250 VDC--accommodating larger string sizes and higher voltage panels.
