Ultimate power inverter/charger question

At times when you're not using the inverter just turn the converter back on again.

It's an inverter/charger.

The storage I'm hoping won't be too big of an issue..... there is a bit of angle at the top front where I will mount it. So my hopes are it will not impede storage too bad. I won't know for sure until I grab her out of storage.

I like the idea of putting plugs on to easily swap supplies if need be.

Does the inverter/charger have a fused 120-volt input? If not you should wire it into the power center breaker panel where the converter is now connected.

It has a breaker on the ac output. But I should probably put another breaker on the shore power line going to the inverter. Better safe than sorry! Thanks!

I posted this yesterday, but people must have missed it. The pdf manual is linked in this, scroll down. Do what it says.

It does have an automatic transfer switch built in. You are better off REMOVING the old converter and hooking your 12VDC fuse panel directly to the battery bank.

From the manual

While in the Standby (charging) Mode, the AC input is continually monitored. Whenever AC power falls below the Trip voltage, the inverter automatically transfers back to the Invert Mode with minimum interruption to your appliances - as long as the inverter is turned on. The transfer from Standby mode to Inverter mode occurs in approximately 10 milliseconds. And it is the same time from Inverter mode to Standby mode.

Not removing but rather just disconnecting the OEM 120 power feed to the converter may be a better choice.

Both yes and now. First the existing converter (I gather it's part of the breaker panel) you can disable. Just turn off the breaker or lift the wire off the breaker (you may need to do a bit more work than this)

Page 2: Now the inverter should be placed NEAR (not next to but in the next compartment over) from the batteries.. With a 3KW inverter you need BIG, HEAVY cables connecting we are tralking 00 or 0000 depending on the run. And a big fuse (30000 watts is around 300 amps at 12 volts so you may need a fuse... bigger (read the owner's manual for the proper size)

But wire that big is EXPWENSIVE so make sure you keep the run short as possible.

Final bit of advice. tape the black and red 12 volt wires side by side for as much of the run as possible.

Suggest battery size. One pair of GC-2 (6 volt two in series make 12) per thousand watts.

with it can't I just bypass my stock converter/charger.

Yes. On my RV, it was easy to do.

Here's how I did it.
