How long it will be last, if harness my power inverter by batteries only?
The runtime of an inverter powered by batteries determined by the three factors:
- How many power your battery drawned to your inverter:
This means how many battery power being drawn from the inverter at a given time, and make sure the demands lower than the max input power of your inverter, E.G. the max battery input power of 6KW hybrid Deye inverter “SUN-6K-SG03LP1-EU” is 60V multiple 135A = 8100W - The capacity of your battery:
Like the fuel tank in your car, if your battery is 5KWH, 8.1KW battery input power will last more than a half hour ideally - Resistance of the solar system:
This is hard to get the percise figure, usual 85-98% efficiency rate
The discussion just like a math question, make things easy, the solar system will support more time if the demands decreased, vice versa, and it is now stable but evenly like a wave, because almost equipment we use is uncontinued like air-condition, refrigerator or so, they will need far higher demands than usual when it work hard
