House Batteries Disconnect Switch & Inverter

If that inverter is this one, it says:

"Back-up Capability with exceptionally fast transfer time just like the UPS - If incoming shore power is interrupted by external events like brownouts, the Freedom X automatically becomes an independent power source that supplies utility grade AC power to your loads when installed with
DC battery"

IMO you don't want it to automatically come on whenever you disconnect shore power. That means with this model, you do need to be able to disconnect the DC input.

Also, Some RV's the LP and CO2 detectors are NOT connected thru the Kill switch solenoid. Basic rule of thumb is, the Kill switch is for short term disconnect. The BEST way for long term is to remove the Negative cables on both Battery Banks. IF you do not have 120 Shore available for long term storage. Doug

Thanks for the replies. I assumed all along the kill switch disconnected everything, including the inverter.

With kilowatt or larger (i'm not sure of the cut off) inverters and inverter/chargers the STANDARD way of hooking them up is the following

Inverter--Batteries---T--Switch--Housew

The T (Tap) is for thigns that need to be powered FULL time no cut off.

Same for Inverter/Chargers.

WHY 1500 watts is about 150 amps draw from the batteries (NOTE I know that is not accurate but.. Well it is downright close by the time you figure in conversion loss and so on it's amazingly close up to about 1000 watts and not far off above that) and that is a bit hard on the Cut off switch.

Also the inverter needs to be as close as is physically possible to keep the very expensive per foot big 00 ga cables short.

That's why I installed battery disconnect switches on the battery posts for both banks.

Yes, A CORRECTLY installed Inverter/Charger ALWAYS bypasses the Disconnect for the Coach batteries. The Inverter/Charger is connected direct from the Coach Batteries to the Inverter. The main reason is simple. MOST battery disconnect solenoids are rated at 100 amps. There are a few in larger RV's that have a 200 amp disconnect solenoid. When INVERTING, the amp draw current can easily exceed 200 amps if powering a large appliance. Which you do NOT want thru a Disconnect solenoid. This is why it is critical for RVer's to ALWAYS check the status of the Inverter when storing the RV or taking it in for service. I will bet 75% of the Motorhomes that are in for work at my Shop, the Inverters are left on and after a few days the coach batteries are dead. Doug
