wiring res fridge

His 550W solar should keep the battery charged for most days.

So, - plug it direct. Then go on grid, turn inverter off - ops, fridge stops. Or don't turn inverter off, let the battery cycle like crazy and keep your fingers crossed that converter will catch up. Or get ATS. Plenty of choices :)

Yes, dedicated inverter can do, and it doesn't have to be powerful, your fridge is probably ~100W.

Why would the battery cycle at all with 100w load? Converter will easily hold float voltage. Only cycling will be when off-grid camping.

You don't ever have to unplug it from the inverter. It will supply power whether on shore power or not. Not sure why this is so hard to understand. Most new trailers with res fridges have the inverters at the fridge and they just stay plugged into them all the time.

While we can SPECULATE on the best way, we really need more information on exactly what equipment you have.

Answers will/should vary depending on:

Do you have an inverter only or is it an inverter/charger?

If inverter/charger, does it have a built in ATS (as most do)?

Tell us what equipment you have and the answers will be a lot more "on target".

Just plug it into the inverter, no need to unplug etc. You might want to consider a smaller more efficient inverter dedicated to the refer. Presumably you've sorted out battery capacity, charging, PSW vs MSW, installation of the res refer and other possible concerns.

x2 ... automatic would be my choice :)

You guys agree making this way too hard.

Plug it into the inverter behind the fridge. Leave it plugged into 12 volt power. It will power it directly off the batteries when no 120. When 120mis there your converter will power it indirectly through the action of charging the battery. No switches, no unplugging or replugging. It works just like the 12 volt lights in the trailer

Mostly drycamp. Would like to power up before departure. I have
550w of solar. I guess I could plug direct into inverter
then manually switch when using shore. ATS would be
the best.

what inverter ?
something that is invert ONLY or a combo inverter charger ?

what converter-charger do you have ?

if the amps are enough say 45 or more
you can run the fridge of inverter direct ALL the time
and when you have shore or generator the converter will charge the batteries and
power the inverter

OR
you can put in a transfer switch 'ATS' so that it auto switches and all charging power can goto the batteries, minus only the lights etc.. for faster recharging

do you dry camp ? or are you primarily with hook ups ?
