Maximum current drawn by the inverter?
Maximum current drawn by the inverter? There is a lot of need to know how much current the inverter can draw from the batteries.
Or what is the maximum current of the electric inverter that is drawn from the electric battery? This question is frequently circulated among those concerned with the subject of inverters and batteries.
Factors affecting the maximum inverter current
The maximum inverter capacity depends on two important things:
- Conversion efficiency of the inverter or inverter.
- Approved battery voltage.
We usually need to know the maximum inverter capacity when we want to install a DC circuit breaker or a DC fuse between the batteries and the positive and negative inverter inputs for connecting the batteries.
The aim of determining the maximum capacity of the inverter and clarifying the necessary protections is to protect against current in excess of its capacity and short currents, and to protect the inverter itself.
What is the maximum current drawn by the inverter?
In order to determine the maximum current that the electric inverter or inverter can absorb, we have to determine the voltage value of the approved battery system. For example, if we have a 2000-watt inverter that works on a 12-volt battery, then it theoretically carries a current of 200 amperes.
However, in practice, the matter differs slightly, because there are several other factors such as the efficiency of the inverter, and the lowest voltage of the battery, as we know that the value of the battery voltage decreases once it is loaded.
The maximum current that the inverter can withstand is calculated using the following formula:
For ordinary inverters, the efficiency will be 90%, while solar energy inverters are approximately 95% efficient, but it is preferable to refer to the data sheet for each model to know the exact efficiency.
Table of minimum voltage values for battery systems
| Battery voltage V DC | Lowest effort CUT-OFF |
|---|---|
| 12 volts | 10.5 volts |
| 24 volts | 21 volts |
| 48 volts | 42 volts |
Calculating the maximum current that the inverter can withstand
If we have a 2000 watt inverter with an efficiency of 90%, what is the maximum current that the inverter can withstand?
the solution:
If the inverter operates on a 12 volt DC battery, then:
The maximum current that the inverter can withstand = (inverter capacity x efficiency) ÷ minimum battery voltage
= (2000 × 0.9) ÷ 10.5
= 1.800 ÷ 10.5
= 171.4 amps
If the inverter operates on a 24 volt DC battery, then:
The maximum current that the inverter can withstand = (inverter capacity x efficiency) ÷ minimum battery voltage
= (2000 × 0.9) ÷ 21
= 1800 ÷ 21
= 85 amps
If the inverter operates on a 48V DC battery, then:
The maximum current that the inverter can withstand = (inverter capacity x efficiency) ÷ minimum battery voltage
= (2000 × 0.9) ÷ 42
= 1800 ÷ 42
= 47.6 amps
We conclude from this that the maximum inverter current decreases when the system voltage of the electric batteries increases, as we noticed that the inverter has a capacity of 2000 watts and carries a maximum current of 171 amps at a 12 volt battery voltage.
Whereas, if it is the same capacity as the inverter, but with a 24 volt DC system, then the inverter can withstand up to 85 amps.
