12VDC/24VDC/48VDC 1000W Inverter
How many Amps does a 1000W inverter need to start? In fact, such a question is not very accurate, we need to specify the battery voltage before we know how many Amps are needed. Before determining the battery voltage, let's understand the working range of the inverter for the battery voltage.
Different battery voltage require the different current. We take 12VDC 1000W as an example, in the state of 10VDC, 1000W inverter calculation work formula is: output power / battery voltage = current , that is:
I=P/U: 100A="1000W/10V," the inverter considered has conversion efficiency, The conversion efficiency of BP series inverter with 12VDC is 88%, the current at the battery end is 100Amp/0.88=133.6A. To be precise, in the state of 10VDC, the maximum current required for 1000W inverter is 133.6A. When the battery voltage is at 15.5V, 1000W/15.5V=64.5A, the conversion efficiency is 88%, and the current at the battery end is 64.5A/0.88=73.2A.
The BP Series 1000W pure sine wave inverter is tested by a Youtube host with 316K followers to see what kind of equipment it can run.
