We have a very small inverter -- we turn it on when we need a/c power, such as for charging a phone. When I am running the furnace and the pump and the inverter with a charger, the voltage readout on the inverter sometimes drops to 11 volts momentarily, triggering a brief but loud alarm. And a really big load, like trying to charge a laptop, will cause the inverter to turn off altogether.
I know the battery is fully charged -- this is a group 31 with 110 amp-hours, at 12.7 volts in a resting state.
So that is my question -- if I get a bigger inverter, will it still drop to 11 volts and emit that shriek? Would a bigger inverter charge the laptop?
Sorry if this is a naive question, but we have resisted getting a more expensive inverter since we so rarely use it. Thanks in advance for your advice.
The wire feed to the inverter is to small, getting a bigger one will just make it worse. Wire size to a 400 watt inverter should be no smaller the 10 AWG, short run, or better yet use 8 AWG.
