Residential fridge/inverter??

Thinking of going to a residential fridge. I have a 2002 HR rambler class A diesel pusher. My question is will my current inverter actually run a residential fridge while we are going down the road?? TIA

What inverter do you have?
Mine does but I have a 3000 watt SW inverter.

How big is your inverter, how much power will the fridge consume? Your engine alternator should be able to replenish any power drawn while driving. Just make sure you have fully cross-connected chassis and house battery system, I don't think using a 'Trik-L-Charger would handle the draw.

Will check on inverter size. I do have a trik-l-charger and Iím assuming that it is cross connected with the batteries. Are you saying Iíll need a bigger batt charger, even if my inverter is large enough?

If you look at the wires that connect the two battery groups together on a Trik-L-Start, it's not sized to carry many amps between batteries. A regular battery isolation relay is much larger and can handle all the charging amperage an alternator can produce.

A Tri K Start is a single direction device. It is there to charge your chassis battery from your house battery, while on shore power at a campground. It has no function in your engine charging system.

If your charging system is charging your house batteries while going down the road, the system in place has the capacity to handle the inverter load, running a residential fridge and lots more.

That makes sense. Thanks!

Easy to test, take voltage readings at house and chassis batteries with shore cord unplugged and engine off. Start your engine and take a second set of voltage readings. Then shut down engine and plug-in shore cord, take a third set of readings. This will show if your batteries connect for charging current from house, chassis side. or both.
