We are at a campground in Laurel,MS 
Had 3 ceramic space heaters plugged in around the coach to get us by for the night.  Wifey turned on the microwave and blew something. The bedroom heater is  running but the front living room area and bath areas and microwave and fridge are not running
- we checked the gfci in the bath area and it is good but no power. 
- checked the breaker in the driver side bay inverter compartment and it is not working. 
Not sure how to check output on the inverter but it an old Freedom 25 that I was planning to replace :-( 
We can run the Aquahot on electric and diesel so we won’t freeze but worried about the fridge… 
I’ll check each outlet with an amp meter to see if they are indeed working or not.

Your freedom inverter should have two small white breakers/ fuses on the back or front- see if they are out and push them back in if you can reach. Hopefully this helps!

We figured it out! There are three little breakers on the front of the inverter and it is really hard to tell if they are off or not

This reminds me of an issue I had the other day, the power flashed off at our place where we have the coach plugged in. We went in the coach to check on some things and noticed a puddle on the floor in front of the refrigerator, opened it up and noticed the it was not cold. All the ice in the ice maker melted and that was most of the water on the floor. So I went down and checked the breakers on the little panel next to the inverter in the bay and things still did not seem right. I tried the microwave and it was not working correctly, seemed to be low voltage. I went back to the house panel in the bedroom closet and I cycled the breaker for the inverter/charger and that seemed to do the trick. So not sure if the transfer switch in the inverter got partially stuck or something. I did not end up doing any testing as that fixed the problem, so I do not know exactly what was going on.

I have a Magnum 2812.

A Magnum 2812 inverter has a pass-through limit of 30 amps per leg, meaning you can utilize up to 60 amps total AC power by using both input lines (HOT 1 and HOT 2) to pass through the unit while also charging batteries; however, the exact configuration depends on how you wire the AC terminal block based on your power source and desired usage.

Let's just say that all 3 of your heaters were drawing the max of their 1800 watts, and your micro drew 1800 watts. That is 15 amps per device. Totaling a potential max draw of 60 amps on one leg, twice what the Magnum would like.

My point is this, if one is going to use high wattage devices in the motorhome, plug them into circuits that are NOT on the inverter based circuits to prevent overloading the internal transfer switch of the inverter. I have to think that overloading the internal transfer of the inverter is not healthy for it in the long term.

Thanks Jesse, Jeff, Richard - I never realized how many plugs/devices are on that inverter line… I am going to definitely be investing in a wireless smart monitor for the refridge/bay/inside temp that I can monitor when away from the coach. Not related: I think I may have found a new place to keep our RV that has 50-amp indoor storage and if I can get a spot there will be switching soon… would be nice to be able to plug it in and run/test all the components… maybe we should head to Quartzite and finally get our lithiums and solar panels! That would have come in very handy the last couple days. I get tired of calling an RV park that says ‘oh yeah, we fit big rigs like that ALL the time!’ Only to find out that they have 10-point turns and gravel or very uneven concrete pads… I don’t know what the place we stayed at yesterday was thinking…

Well, it’s back now… we are at the Atchafalaya rest area in Louisiana on our way to TX to visit my Mother who just went into Hospice care :-( Everything attached to the inverter is dead in the coach - all other systems are working fine. We are still. I have not been able to test the chassis/coach battery banks but did check the fuses on the inverter and they were already pushed in…question: is there a way to disable or bypass the inverter?

[pairodice]

So I may just find a used inverter same size locally on FB Marketplace…

Looking at this one - what do you guys think to replace the freedom 25?

I have no experience with the sw3000. I’ll say that my old Xantrex Freedom 458 has worked well for 10 years. I’m wondering if your invertor just needs a breaker replaced. It’s not uncommon for them to get weak over time.
