The controller is designed for solar dc lighting system, there are several optional working modes, and has two output terminals, with separate time set.
Specification: 12v, 12/24v, 5a, 10a, 15a
Use mcu and professional software as the control center to fulfill intelligent soc control, protection to overload, outside and insdie short circuit, reverse connection, thunder and lightining, pv panel reverse current, over charge and discharing etc, usd pwm high efficiency charging way and temperature compensation.
Industry level production standard, led indication on system condition.
The controller pcb is pained with england apl lacquer, its highly moisture-proof
Suunny solar charge controller is controlled by cpu, according to the voltage ofbattery, controller will adjust the charge current and decide if to supply the loads electricity. The following is the detailed performance:
Generally keep the battery on full voltage condition.
Prevent the battery from over-charging.
Prevent the battery from over-discharging.
Prevent supplying electricity from the battery to solar panels during nights.
Reverse polarity protection for battery
Reverse polarity protection for solar panels
When the current of load exceeds the rated one of controller, the controller will turn into the self-protection state and is automatically locked up, the screen shows overload.
Short circuit happens; the controller will turn into the self-protection state and is locked up, the screen show short circuit.
Low voltage happens to battery, the controller will automatically separate loads from system. When the voltage of battery goes up, the loads will automatically restart to work.
Protection from the lightning strike
When controller is normally working, the lcd screen will show new charging current (a dash-before the numeral) , discharging current and voltage of battery every 5 seconds.

Solar charging controllers for camper
Charge modemppt
System voltage12v
Battery numbertwo battery charging ports
Battery typegel, lead-acid, agm2, lifepo4
Application
1.For camper, caravan
2.Self-contained solar systems
3.For boat
1. Increased mpp charging current compared with conventional controllers, due to ultramodern controller technology (microprocessor)by 10 % to 30 % (efficiency > 95 %)
2. Switchable characteristic lines of charging for optimum charging of gel/dry fit/agm/fleece or acid/lead-acid, as well aslifepo4 batteri es .
3. Two battery charging ports: automatic charging of the main battery or board battery (board i):
Support charging and trickle charging (max.1 a) of the vehicle's starter battery (start ii) with overcharge protection
4. Unattended charging: standard protection against overload, overheating, reverse battery and back discharge of the battery(in case of insufficient solar power, such as at twilight, at night etc.).
5. Overcharge protection: reduction of the charging current of the battery in case of excessive solar power and full battery. Immediate recharging in case of power consumption to ensure always the best possible charging state of the battery.
6. Connection for temperature sensor , automatic adaptation of the charging voltage to the battery temperature. Incase
Of low outside temperatures, full charging of the weaker battery is improved, and in case of summery temperature sun necessary battery gassing will be avoided.
This is highly recommended, if the battery is exposed to strong variations in temperature, such as in the motor compartment.
