Just asking. Is it OK to leave MH plugged in when stored at home? I use a 20 amp outlet and an extension cord, but wondered if it is Ok to leave it for extended periods of time.

Thanks,
Ezgoin’

Depends on your inverter / charger , if you have a 3 stage that will adjust your charge rate and not boil off your batteries then it Should not be a problem leaving the power connected . If not then you would need to keep an eye on your batteries to prevent boiling off the water again that is if your running wet cell style batteries.

I keep mine plugged in. But suggest you open your purse and install an outlet for the amps your unit is designed for 30/50.

Do you have surge protection? What is the frequency of lightening in your area?

When I had a home and a drive way, rather than an apartment, the coach was on power from Easter to Thanksgiving. Multi stage converter/charger so never had a problem with the batteries needing water.

I keep mine plugged in and the A/C on at a high level during summer to limit the interior temps and have heaters during winter to keep from having low temps(although this year never needed them). Also keep water in toilet to keep seal from drying out.

Mine has been plugged in by my house for 12 years. So far, so good.


You need to check your batteries for water once a month or so.

In Florida our RV is our life boat during hurricanes, tornadoes, so it must be ready to go at all times. We always leave it plugged in and never had a problem. We have had to bug out and we have had to use the RV generator to supply power to our house freezer and refrigerator when without power for a few weeks after a storm passed. Our fresh water tank is always full and our fuel tank is always full, and we are always connected to shore power to insure that the batteries are fully charged. We also keep a trickle charger hooked up to keep the chassis batteries fully charged since our inverter/charger only keeps the house batteries topped off.

If you are just maintaining things, your 20 amp hook up is fine. I use one myself but do have it on a timer so it just gets a squirt of electricity in each day.

Just so you know.. I think any RV made this century (Which means 2001 or later. not 2000 though it would be a very low end in 2000) you should have a decent converter.

1980's you might get a Magnetek 6300.. (Very bad) known for killing batteries fast.

but Parallex bought out Magnetek if I'm not mistaken and did a few "Upgrades" so

Parallex 7300: Single stage good regulation may be left plugged in but the first time check batteries both voltage and fluid level (if flooded wet cells) from time to time. Voltage daily for the first 2 or 3 weeks should do it)

Parallex 7300T: This unit has a TIMED boost period (T for Two or Timer) slightly better.

WFCO this unit has a high failure rate but when it's workign it's a good 3 stage (Boost/Absorption/Float) when it "Fails" Well see note below but usually it fails safe (Float only).

FOrget the name of the one with IQ4 Technology (Ilco?)

Progressive Dynamics With Charge Wizard

These are the best of the best in my book.. 3Stage +

Most Inverter/Converters.. I'd give them about a 9.5 on a scale of 10. also very good.

NOW: failures
Any converter can fail in one of 3 ways.
Fail to go into boost (WFCOs most common failure mode)
Fail to charge at all (my PD did that)
Over charge. This last is rare but it does happen.
