mcb circuit breaker u low voltage alarm

1. The batteries need to be recharged.

2. Battery voltage is too low or bad, recharge, check the battery terminals, or with a dry cloth to clean the terminals.

u no the inverter output

1. Battery voltage is too low to recharge or replace the battery.

2. Load current is too high mcb circuit breaker‍, the power transformers‍ closure of some load restart inverter.

3. Inverter over-temperature protection. Let inverter cool for some time, and well ventilated place.

4. The inverter fails to start, restart.

5. Terminals reversed, the fuse is blown, replace the fuse.

u inverter does not work

Check the power switch, fuses and battery cable or cigarette lighter.

Inverters DC input

The reason of such failure often happens is the battery is not connected properly, positive and negative terminals of the inverter must be connected correctly and battery positive and negative, positive then positive, then negative negative, right after connecting the switch is closed, basically you can Electric transformer‍ solve such malfunction.

Inverter input and output fuse

Such failures are generally apparent that, as long as you can replace the fuse.

Battery voltage is higher than the nominal DC input voltage of 20%

The inverter has an operating voltage range, typically rated DC voltage of + -10%, should the higher the voltage, the need to replace batteries or replace the inverter in order to prevent damage to the machine.

Battery voltage is lower than the nominal DC input voltage of 15%

Such problems are mainly due to lack of battery power, you can just give the battery pack.

Load power is too large

Such pre-load problem is caused by lack of AC Contactors‍ power calculation, you need to increase or decrease the power inverter to power the load.
