Inverter Hard Wire install

Finally finished the install today, and all the tests worked wonderfully, causing uncontrolled dancing in our driveway. What inpressed me most was the fact that our Honda eu2000 can drive nearly 100 amps into the batteries in bulk charge mode. It was also a treat to see the remote panel for the inverter go from inverting to charging when I plugged in the shore power (and the youtube video I was streaming never missed a beat.

I ended up rerouting the 50amp 6/3 wiring from the fuse box directly into the input side of the inverter/charger. I then ran a second 6/3 line from the output side back to the fuse box. And I flipped the stock converter breaker off, where it will stay until we someday sell this rig and I revert the wiring to stock.

Hi Tim,

I posted that not to say I'm special or superior, but to cast doubt on the 30 amp transfer switch. In your shoes I would email Magnum with the serial number and see if you have a 50 amp transfer switch. I was not trying to rain on your parade.

The 2812 is an excellent inverter. The 3012 is slightly better because of the hybrid nature and the built in load support which I use almost every time I'm plugged into shore power.

Understood, and thanks for the clarification. No hard feelings.

I know the 3012 hybrid Magnum has a 50 amp transfer switch in it. It is superior in all ways to the 2800 watt unit and almost the same price.

Thanks. That is very helpful in my thread that started with, I purchased the 2812. Yours is better. Congrats.

Check out the selection of fifty amp DPDT relays sometime.

Seems a shame to have to kludge up an installation with a $2000 IC.

Check out the selection of fifty amp DPDT relays sometime. Now stack a second one alongside. Solid State relays are no option because of the massive heatsink needed.

It is 30a on each leg.

I don't quite get why Magnum would provide a "50a" IC with 30a switches, assuming that means you do not want to be sucking more than 30a thru them at any time.

Bad plan, the inverter is 2800 watts, the transfer switch is likely 30 amps max, You run the 50 amp line to your main breaker box (where it runs now) and then run a 30 or 35 or 40 amp BRANCH line to the inverter.

Inverters come (for this post) in two flavors, Those with breakers included, and those (like mine) without

if yours has breakers included you run branch circuits off those breakers

If like mine You run a same size line (30 amp needs at least 10ga wire, Higher amps more wire) back to a SUV panel, This is a breaker box without a "Main" breaker, the incoming power goes straight to the bus bar.

Then you run branch lines from there. Mine (2000 watt) feeds the Microwave, TV's (All of 'em) also my computers (Same branch) and the GFCI chain. (Bath, Kitchen, patio, Dining room table)

Side note: I have a wireless doorbell i got from PCH.. This one is different from all the others I've ever had in that the receiver (Bell) is battery powered, Since the receiver runs 24x7 it ate batteries.. 3 of them about every 2 weeks (Expensive) I cut and pasted (Ok Soldered) a USB cable to the battery contacts in the unit, Removed the batteries, Plugged a 5 Volt USB charger adapter into the Microwave circuit (used a 3-way cube) and now .. it is "mains" powered. IF Mains fails the inverter kicks in every bit as fast as a UPS so the TV's, Microwave and of course computers and doorbell, Do not even blink.

Do not leave the power cord to the RV "hot" when running the inverter.

Use a transfer switch that is active when on shore power.

That won't happen if he wires it per directions. He has a xfer switch in the IC.
