Promotion! High quality Inverter+UPS off grid solar inverter 3kw

Function:

1, Auto Voltage Regulation(AVR): When utility power is unstable, this machine owns precise and stable voltage output function. For example, in China, the utility voltage can drop to 190V at peak demand, but the output voltage of this machine is 220 V±3% V, 50 Hz±0.5, which can help to protect electrical equipment.

 2, DC/AC Conversion Function: When the utility power fails suddenly in the home, office, supermarket and industrial zone etc, it can be an environment-friendly engine; in some outdoor areas without electricity, it can be used as Mobile Power and provide AC power for household appliances.

3, Intelligent Charging Function:. When batteries run out of power, inverter can be connected to the utility and automatically charge the battery. When connected with utility and battery, it could be used as a UPS system and will charge batteries automatically when connected with utility,  The charging process can be divided into three sections. Section I: With largest constant current charging, this can improve the backup power. Section II: Constant voltage charging to charge batteries gradually, then there is enough time for batteries to absorb energy .Therefore, battery electrodes are protected and battery overcharge can be avoided. Section III: When the batteries are fully charged, the output of inverter will turn into float voltage to maintain full power state of batteries for a long time.

4,UPS Function: When this inverter connected with batteries and utility, inverter will start its UPS function.

Step 1: When utility power is available, it will output directly after stabilizing voltage and charge batteries simultaneously.

Step 2: When utility power cuts off, the system will convert DC power to AC power to ensure uninterrupted power supply.

Step 3: When utility power comes back, the system will turn into utility power supply automatically within 5 ms and charge batteries simultaneously.
