However, the inductive load appliance has a starting power of 3-7 times, the continuous power meets the condition, and the starting power must also meet the conditions before it can be driven.
FOR EXAMPLE
If the battery is 12V/60AH,can you use a 2000W inverter with a 500W hard drill ?
1.First look at the maximum battery charger is :12*60*0.8 = 576W,>500W.
2.Determine whether the electrical appliance is a resistive electrical appliance or an inductive electrical appliance: the hand drill is an inductive electric drill.
3.The continuous power of the hand drill is 500W,and the duration of 2000W is 1000W,>500W.
The starting power is generally about 3 times (the starting power of dofferent electrical appliances is different) so 500W X 3 = 1500W, the starting power of the 2000W inverter is 2000W,>1500W Therefore,the 500W hand drill can be used with a 12V/60AH battery and a 2000W inverter.
Other appliances can also be judged by this method.
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 alarm
1. 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.
If you have problems, do not understand the operation, you can also consult customer service, thank you!
