384V Solar Charge Controller Sandi Series Solar Charge Controller is a smart PV controller designed for off-grid PV power system. It has good running performance with LCD display and convenient operation. And also automatically control solar cell cut or connect ordinarily according to the change of battery voltage. This controller makes a full advantage of solar cell resource and also keep battery safe and reliable.
To meet different power stations’ need, there are 24V,48V,96V,120V,192V,220V,240V,360V,480V and other normal series voltage level base on different battery voltage of off-grid PV power station system project.
PERFORMANCE FEATURES:
1.Design for off grid solar power system.
2. Applicable to different kinds of batteries.
3. Modular design with simple structure and easy maintenance.
4. Adopt PWM multistep sequential limiting current charge method, auto control multiple solar array connection or shut off orderly according to the battery group voltage change tendency.5. Big intuitionistic LCD display: Solar panel current, solar panel voltage, solar panel power, battery group voltage, charge current.
6. Completely automatic control protection function, including protection against over charge, over discharge, electronic short circuit, overload and reverse connection, thus the system has higher reliability. Prevent the battery group reverse charging to the solar panel array at night.
7. Adopt multiple-circuit charging-control circuit and individual killer switch on each circuit.
8. All control with industrial chips can run in cold, high temperature and damp surroundings.
9. The inside of the controller is equipped with surge arrester. Limit instantaneous overvoltage which entered into solar panels under a level which the system can withstand; or unload the strong lightning current to the ground. To protect the equipment from lightning surge.
10. The charging current can be adjusted according the accurate measured terminal voltage of the battery, to charge the storage battery progressively full.
11. Temperature compensation function. Compensate the temperature according different battery type.
12. Fixable communication solution with RS-232,RS-485,USB,GPRS, Etherner,etc.
