Inverter Questions

2016 Outlaw 37RB. Has res fridge and an inverter.

I know the inverter takes DC and converts it to AC. Tell me when I need to have the inverter on and when can I turn it off.

Running down the hi way = on or no fridge. Correct?

Dry camping = ???

Generator running = ???

Plugged into shore power = on or off?

We are new at this so any help will be appreciated. Thanks

Basically, any time you're using the fridge in the RV, the inverter needs to be on. The only exception is if the inverter has a pass-through mode that works when it's off. If it does, it can be off when on shore power or generator.

Looking at the feature list for your RV, I would expect that the inverter does NOT have that mode since it lists separate inverter and converter. Pass-through mode is only possible on combination units.

OK. Thanks for the info.

Reason I was asking is because RV is winterized and has been parked for a little over a week now. When I shut it down I switched house batteries to store but did not turn off the inverter. Today the house batteries we a bit low, 11.9. So I turned the inverter off and plugged it into shore power to help charge the house batteries. I'll go check it tomorrow.

If it's winterized, then block the fridge doors open and turn it off. And turn the inverter off.

Do you have a Inverter/Charger Combo?
If this is the case you shouldnt have to turn the inverter off, since your residential fridge will only run on AC. If plugged to Shore Power, the transfer switch should switch to shore power and if you have the combo, the charger portions continues to charge battery.
If Generator is running the transfer switch should also switch so no need to turn inverter off or on.
Now if you have the Refrigerator PLUGGED into a Cheapie Inverter then it must be on all the time. Depends on how your fridge is plugged in.

Most inverter/chargers also have a built-in transfer switch, aka "pass through: so that the inverter doesn't actually run when shore or genset power is online.

A few plain inverters also have a transfer switch built in, but most do not. However, a factory installed inverter might well have an external transfer switch that provides a "pass through" as well. Hard to know without detailed info on your particular rig. It's pretty easy to tell, though. If the fridge doesn't come on when plugged to shore power and the inverter is off, you will know you need the inverter to operate the fridge. Always.

When in storage, you don't need to operate either one, right?

I don't know what I have. LOL

Like I said, I have a lot to learn.

The unit itself is mounted on an outside compartment wall beneath the fridge. There's a control unit on wall just inside entry door with a digital read out and an off switch.

A lot depends on the inverter. Factory installed or in many cases (mine included) After market I leave it on all the time.. IF SHORE or Generator power is present it auto-switches to standby and passes power to the loads... Oh, I have an RV type absorption fridge so it does not power the fridge.

OFF.. Well it depends on how OFF I turn it.. But this is not always the case.. On mine TRUE off (Big red switch on Inverter itself) Nothing works, NO TV, no Microwave, No GFCI chain (kitchen, bath, patio dining table outlets).

ON but disabled, The above all work on shore power, and if the charger is enabled batteries charge But if shore power is lost. All die.

On and enabled.. (NOTE: I disable the charger for reasons which likely do not apply in your case.... I like my other charger better).

On and Enabled (inverter) If on shore power everythign works on shore power.. If Shore power is lost as it was last week.. i do not even notice. The TV works, The Microwave works, The Computers Work, the Wi_Fi Modem and Router work.. it all works.. Had I not looked at an "Shore power present" indicator I'd have not known it was missing since I did not have the A/C on.

Xantrax has several 1800 watt inverters. Inverter only include the PROsine 1800, PROwatt SW, and XM 1800. Inverter/Charger model is the Freedom HF 1800.

Which model, specifically?
