1. Features:
1. Intelligent design succinct structure, control powerful, stable performance, safety and reliability of the products.
2. Choose MPPT fan charging ways, charging more efficiency than ordinary PWM way more superior
3. Choose the big size LCD display, all parameters can directly visible
4. The humanized keys operate function, all of the parameters according to the request of customers in orders to adjust all kinds of using environment.
5. Using LCD to show the tinny battery voltage and electric current
6. With output state should set function, common power/half power/of period of time since the definition and characteristics (optional)
7. Should the utility complementary function, uninterrupted soft handoff, guaranty load to continue to work. (This function should be customized)
8. Professional digital intelligent control.
2. Protections.
1. Waterproof protection
Waterproof degree::IP32.
2. Input power limit protection
When the PV power exceeds the rated power, controller will limit the PV power under the value of rated power so as to prevent the controller from being damaged.
3. Battery reverse connection protection
Battery reverse connection will not damage the controller but the system will stop working.
4. The voltage of PV input terminal is over value
When the voltage of PV input terminal is over value, controller will shut the PV input automatically.
5. Short circuit protection of PV input terminal
Load short circuit will not damage the controller but controller will stop output.
6. Over load protection
When the load current exceed 1.25 (or 1.5) time of rated current and last for 10s (5s), the load will stop output.
7. Load short circuit protection
When the load is short circuit, controller will stop output without any damage.
8. Solar panel reverses connection protection
The reverse connection of solar panel won't do any damage to the system.
9. Reverse charging protection at night
Prevent the battery from discharging through solar panel at night.
10. TVS lightning protection
11. Over temperature protection
When inside temperature of the controller is over value, the controller will lower charging power or stop charging.
3. What is MPT solar controller?
MPPT solar controller is designed for solar power system design; Equipment can not only efficiently transfer issued by the solar panels to recharge the battery power, but also provides a powerful control functions.
Features: The controller is characterized by intelligent adjustment of the operating voltage solar panels, solar panel always working at the VA characteristic curve of the maximum power point. More common, solar controller, solar panels for power generation increased utilization of 10-30%!
The controller uses solar panels for intelligent charging of the battery. In the solar panel power than the battery storage capacity, the control system automatically cut off the charge, thus ensuring optimum battery charging features, making full use of electricity.
As the battery can only withstand a certain degree of charge current and float voltage, over current and over-voltage charging the battery will cause serious damage. The controller battery charge grams of real-time detection voltage and charging current, and by controlling the charge current to limit the photovoltaic battery charging voltage and charging current to ensure that both the battery is full, it will not be damaged. To increase of the battery service life.
