3. Working Principie

During the day, under light conditions, the solar cell modules generate a certain electromotive force, and the solar cell array is formed through the series and parallel connection of the modules, so that the voltage of the array can meet the requirements of the input voltage of the system. Then charge the battery through the charge and discharge controller, and store the electric energy converted from light energy. At night, the battery pack provides input power for the inverter. Through the function of the inverter, the DC power is converted into AC power, which is transmitted to the power distribution cabinet, and the power is supplied by the switching function of the power distribution cabinet. The discharge of the battery pack is controlled by the controller to ensure the normal use of the battery. The photovoltaic power station system should also have limited-load protection and lightning protection devices to protect the overload operation of the system equipment and avoid lightning strikes, and to maintain the safe use of the system equipment. Solar → Electricity → Chemical Energy → Electricity → Light Energy

4. Feature

1). Battery charging function: The all-in-one machineduring the day can constantly send the solar panels’s energyinto the battery, can adjust the charging current according to battery voltage, in order to prolong the service life of storage battery, it also have floating function, keep the battery in a full status for a rainy day. In addition the all-in-one prevent reverse charging battery to solar panelsat night.

2). Battery undervoltage protection function: Using inverter electric power supply for a long time will lead to a serious loss of battery voltage, greatly affect the service life of the battery. The machine can be shut in the storage battery voltage down to 11.0V dc output, 10.8V closed ac output. In order to prevent the over discharge of storage battery damage.

3). Overload protection function: When you access the appliance is overmuch, total power over rating of the inverter, it will stop working for 10 seconds, lock the protection status, and report to the police, until you reduce the load, and the inverter power switch to "OFF" position more than 10 seconds, and then back to "ON" position, the inverter to restore work.

4). Short circuit protection function: When your household appliances internal short circuit occurs, the inverter will stop working in 1 seconds, and lock protection status, and report to the police, until you remove the short circuitshome appliances,and the inverter power supply switch to "OFF" position more than 10 seconds, and then back to "ON" position, the inverter to restore work.

5). Temperature protection function: When you load more, poor ventilation or the climate is hot, the temperature inside the inverter will gradually rise, if the temperature continues to rise to 100 °C inverter will stop working, and lock to protect state, suggest that you reduce the load or to improve the ventilation environment, the inverter power supply switch to "OFF" position, when the internal temperature decrease, and then to the "ON" position, the inverter will come back to work.

6). Status indication function: It have fault indicator, inverter indicator, and multi-function LCD or pointer to the header show,let all status be clear at a glance.

7). DC12V and DC5V output: DC output port for your dc devices charging and power supply function.
