To bring high-power electrical appliances, battery capacity should be large enough

How much capacity (ah) battery is needed depends on how much power electrical appliances are needed.

How much power can the battery take? Electric appliance = battery voltage × Battery capacity × 08

For example: a 12V Car battery with a capacity of 80ah. Electrical appliances with maximum power = 12 × eighty × 8 = 768w. What happens when the battery capacity is small or the power is less: after connecting the electrical appliances, the inverter will appear red light or alarm, and there is no 220 V power output.

Judgment method: you can turn off the inverter switch first, then connect the electrical appliance, and immediately watch the digital display change of the input voltage on the inverter. If the input voltage drops very fast or very low (for example, the voltage of a 12V battery with a full charge is more than 13V). If the voltage drops below 11V and an alarm appears after connecting the electric appliance, it means that the battery capacity is not large enough or the battery power is not enough.

Solution: if the battery capacity is small, it can be replaced with large capacity or multiple batteries, or small power electrical appliances. If the battery capacity is large enough but the power is not enough, it needs to be fully charged or replaced with low-power electrical appliances.

The battery voltage must be consistent with the nominal voltage of the inverter.

Inverter is a kind of converter that converts the direct current of storage battery into 220 V alternating current to supply electrical appliances.

The voltage of the battery must be consistent with that of the inverter. Generally, the car battery is 12V, the truck battery is 24V, the electric vehicle with four batteries is 48V, and the electric vehicle with five batteries is 60V. For example, a 12V Car battery requires a 12V inverter to be paired.

Please use our original wiring because the wire is too long and too thin will affect the current

Because power = voltage × The current is the lower the voltage, the greater the current.

Because the voltage current of the battery is about 10 times lower than the 220 voltage of the household appliance, according to the principle that the voltage is smaller, the greater the current is: that is, the current of the battery is about 10 times larger than that of the household appliances, so the wire connecting the battery is thicker than the wire of the home circuit to make the current pass through the conversion.

Common problems and Solutions

Outside interference

A: The frequency converter may be disturbed by some strong electromagnetic waves in use, such as the strong magnetic field of the nearby motor and power frequency converter, which will affect the use effect.

Inverter does not respond

1. The connection between the battery and the inverter is incorrect, please re connect.
2. The polarity of the battery is reversed and the fuse is blown. Replace the fuse.
Low output voltage
1. Overload, load current exceeds rated current, turn off part of load and restart.
2. The input voltage is too low. Ensure that the input voltage is within the nominal voltage range.
Low voltage alarm1. The battery is dead and needs to be charged.
2. If the battery voltage is too low or the contact is poor, please charge the battery, check the battery terminal or clean the terminal with dry cloth

No output of inverter
1. The battery voltage is too low, please recharge or replace the battery.
2. If the load current is too high, turn off part of the load and restart the inverter.
3. Inverter over temperature protection. Let the inverter cool down for a period of time and place it in a ventilated place.
4. If the inverter cannot be started, restart.
5. If the terminal is reversed and the fuse is blown, replace the fuse.

Inverter does not work
1. Check the power switch, fuse, battery connection line or smoke.
