Temporary use of Inverter

[Warm Vibes]

Good afternoon, I am thinking about purchasing a Renogy 2000 watt pure sine wave power inverter and a Litime 12V 140ah LiFePO4 Lithium Battery. This would be used to supply power to a Harman P61A during power outages until I can get generator going. Literature for inverter states that ground wire should be installed. Is this necessary? If so, how would I install a temporary ground wire to run pellet stove a few hours? Seems every inverter or inverter/ charger I looked at requires a ground wire. My concern is damage to the pellet stove(and myself). Thanks

I am no expert but I think you are providing a ground for the
Inverter through the pellet stove ground, so the whole unit is grounded as one unit.

I am running that sort of system. The difference is that my stove is plugged into the inverter all the time. It is plugged into the inverter with it's standard grounded plug. Then there is a ground terminal on the inverter, which I ran a wire to ground (side of a grounded box). I have a 35A battery charger on the battery all the time. If there is a power outage, the stove will keep running till I hook up a generator or solar panel. I can also just shut it off, and it will be a controlled shutdown ie no smoke in the house.
If you only want to use your inverter part time, then ground the inverter to house ground with a wire.

Make sure your generator is also using an inverter so that the pellet stove will run on a clean sine wave.

Whitenuckler hit it. The ground lug on the inverter needs a ground. A jumper cable between it and your ground wire at the panel will work. It's there so you don't end up as a ground since without it the system is "floating" and can hit you pretty hard.

Rather than using an inverter and a battery I use an APC SmartUPS 750. It gives me plenty of runtime to get the stove shutdown or the generator hooked up. It may be less costly and look better than a separate inverter and battery.

I tried a cheap inverter first, but I blew it during testing. It seems you should not unplug it from the wall to test it. Maybe because it loses ground? Anyway, the lead acid battery was so small in it compared to a 100ah car battery it would not have lasted long. I think it would have struggled to do a dry start with the igniter. I much like 2000W. A good thing with the UPS is they fit behind the stove. I have all my stuff in a separate room behind the stove.

I still have it down in the basement - they didn't want it back, just a full refund from Amazon

Perhaps I'll look into a UPS.🤔

I see I screwed up or AI fixed my paragraph. I meant to say I tried that UPS first. It was $225 CAD. They have a 1500 for $293 which would have been better. If you get one just do the self test. Don't unplug them like I did.

It's a good idea for a couple of reasons. Could be a controlled shutdown (if you are there in time), and buffer the power to save money in new cards and wasting time troubleshooting. Fits behind the stove too.

I use APC 850w UPSs on both my stoves. Note that they are not meant to run the stoves, but to keep them going long enough that no smoke has a chance to back into the room. They have plenty of power for the stoves to gracefully shut down (the stoves pulse the fans until they are cold). That gives me time to hook up a battery station - I actually had to do that the other day from trees that came down in the wind.

I have found that smaller stations (Bluetti AC180 and Ecoflow Delta 2 Max and smaller) will run the stoves fine without a ground. Just plug in the APC UPS to the station and all is right with their world and they will run. The APC will not run a bigger station, like an Ecoflow Delta Pro until there is a ground wire. Don't ask me what the difference is, but that is my finding. I do need to get a transfer switch, which would alleviate that issue.

I always test just by unplugging the APC UPS and have never had an issue with either the 750 or 850.
