It is controlled by micro-CPU, with a perfect SOC management function.Introduction:
It is controlled by micro-CPU, with a perfect SOC management function. They are able to control the charge current and decide whether to supply power to the loads according to the voltage of battery.
It has the following features:
1. It has charging and discharging functions at the same time.
2. Always keep the battery on full voltage condition.
3. Prevent the battery from over-discharging.
4. Prevent the battery from reverse charging to solar panels during nights.
5. Reverse polarity protection for battery
6. Reverse polarity protection for solar panel
7. The loads’ current exceeds the rated current of the controller; it will activate the protection model and lock up, and LCD display shows overload.
8. Short circuit of loads, the controller will activate the protection mode and lock up, the LCD display shows short circuit.
9. Low battery voltage, the controller will cut off the loads and LCD shows battery low, recover to normal voltage and then loads auto activate.
10. Thunder protection
11. LCD display shows the voltage of battery, charging current and loads current in turn by every 5 seconds in condition of working well of solar charge.
12. The controller can store can store the charging current data and discharging current data of the battery.
13. When starts up, the controller will self-setup the charging-off voltage, the load-off voltage and the load-on voltage according to the voltage of battery. these default parameters bring into effect in the standards environment temperature(25°C)
14. The controller will automatically compensate the temperature of the charging voltage according to the changes of the ambient temperature.
15. The charge-off voltage, load-off voltage and load-on voltage could be settled according to user’s requirement.
16. To prevent battery from over discharging, the controller will automatically control the lowest load-off voltage of the load, 12V, 24V and 48V should no less than 10V, 20V and 40V respectively.
17. To recover the default parameters, please keep pressing the button menu for more than 5 seconds.
