I plan on hooking up my house batteries to a switch. I will be able to
switch between off, sending 12 vdc to 12 vdc devices, sending 12 vdc to
my inverter or sending 12 vdc to both. If I have the switch set to
both and the inverter is charging my house batteries, will the charging
cycle by the inverter damage my 12 vdc devices. |

John, You don't ever want to disconnect the batteries from the inverter/charger and you don't want more than 4-5 feet of cable between the batteries and inverter.
It's OK to have a switch between the batteries and your 12 volt equipment.
The inverter charging won't hurt any 12 volt equipment, just be sure to disconnect any 12 volt equipment if using the equalize function of your charger.

That switch had better be a $80+ good marine switch IF the inverter will pull thru it.

John,
Are you aware that 10 amps of 120 Volts AC will require 120 Amps of 12 Volt DC? That's if the inverter is 100% efficient, which it isn't. Actual current draw will be about 130 amps!
All of your 12 Volt appliances are made to run on charging voltage, as they do while you are driving.
I don't see the need for a switch, but if you do, it will have to be rated for 300 Amps, or it will disappear in a cloud of smoke! Needless to say, your cables and connections will have to be able to handle this amount of current also!
Regards,
George |
