Introduction :
PV –systems exposed to extreme weather/environmental conditions (street light,navigation buoys etc) have increased risk for damage in the power electronics. In order to assure reliable battery charge control under such conditions, CARSPA developed an encapsulated charge controller (IP67) to prevent corrosion
SI is an industrial –grade charge controller that is suitable for all practical PV applions. High-quality, 4 stage, PWM-charging is combined with amazing features such as low-voltage disconect , flexible load timer functions and a mutil-LED system status display.

Features :
Robust aluminum housing
epoxy encapsulated PCB to prevent corrosion (IP67)
Compact size
Intelligent timer functions
Widely programmable
3 stage battery charging (boost , equalization, float )
Automatic system voltage recognition ( 12/24V )
There are 3 modes available :
Dusk to dawn and Evening / Morning modes
