Solar Charge Controller
General Details
Solar Charge Controller is used in solar lighting as a mediator between the photo voltiac panel and the battery. In the absence of sun light SCC uses the battery power to switch on the light.
Product Highlights
- Micro controller based MPPT solar charger.
- Automatic dusk-dawn operation.
- High efficiency :>90% for MPPT charger and >90% for LED driver.
- Adequate protections for battery reverse polarity.
- Protected against overload and short circuit.
- MPPT based.
- No load protected.
- Dusk to dawn operation.
- Overvoltage protected.
- Battery reverse polarity/overcharge protected.
- Constant current.
- Battery deep discharge protection.
