which home backup power station should I buy ?

[Whitenuckler]

I’d return it for a victron. I just got the 50 amp. It’s $300 though.

But like many things once you pick a brand you kinda get loved into their ecosystem.

Yes I already have an Ecoflow charger and I’m adding a victron for a completely separate battery system. That will
Be permanently installed in the van. Unlike my EcoFlow delta2 that moves around a lot.

That's $424+15% CAD compared to the sale price of $118+15% CAD for 20A. I think I scored a good deal, but have not tested it yet. I have some anderson plug 50A fused #10 hookup's. I will be able to have one set attached to my jeep battery under the passenger seat. The other two will be attached to the converter and fused at 30A. I bought a roll of #10AWG twin cable meant for marine use. I can have my battery in the tent or in the truck. Just waiting go the battery and it's been shipped.

Yeah, if you use a certain brand, the rest of their stuff tends to just run a little better than mixing brands.

So I received this DJI Power Station 1000 V2 and so far preliminary testing looks good. Even when the well pump comes on (which I am driving from 110-120vac using a transformer (see https://www.hearth.com/talk/threads/power-flickering-from-small-12vdc-120vac-inverter-attached-to-ev.209598/ and https://www.eevblog.com/forum/renewable-energy/home-backup-running-240vac-well-pump-from-120vac-using-transfomer/), the output voltage of the transformer does not drop below 210vac and generally 220vac (the well pump's spec is 200-240vac, so this is good).

There's one issue. I want to be able to charge it from a 1000watt inverter attached to an EV (my previous backup scheme) or from the AC output provided by the SMA SunnyBoy inverter on our grid-tied solar system. The DJI has two charging modes: "standard" is 600 watts and "super" which is 1800watts; mode is selected by a switch and seems to work as specified. However .... if there's a load connected (to an AC output port), the charging power goes up above 1000 watts (even if set to "standard" mode); and so my charging sources shut down. This means I have to disconnect it from AC loads (i.e. my main load center) in order to charge it. This is a significant drawback. I'm hoping maybe it's a firmware issue and can be resolved.

Nonetheless, I think the thing is a pretty damn good deal at $400 or so.

Can you try these somehow?:
SDC: DC 32-58.4 V, max current: 60 A
SDC Lite: DC 32-58.4 V, max current: 8 A

It requires proprietary cable ($300) to connect to the SDC ports, and they also say it doesn't work with EVs - but that may just be CYA: "Hybrid and fully electric vehicles are currently not compatible with the DJI Power 1kW Super Fast Car Charger, due to differences in generator operation compared to traditional fuel-powered vehicles."

They have a $49 12vdc charger, but it's only good for 100 watts, hardly worth the trouble.

I think the SMA inverter (for our grid-tied solar array) may be able to supply enough juice, but only if it's really sunny ;-)

Too bad you need a special cable. Can you MacIver the connector end? I can see your car inverter running a 48V battery charger connected to 4 batteries...I guess at that point it gets complicated again.

I think not; it's XT6 but it also has some handshaking going on.

Just noticed the expansion battery for this thing is $900, for 2kWh. That's more expensive than TWO of the power stations - which is the same amount of kWh plus two 2600 watts inverters for free. I'm thinking this was some kind of intro price to break into this market; I'm thinking I SCORED.

Good for recharging drones too.

Yeah, evidently that is DJI's main business.

That’s what I was thinking use dc charging.

Ecoflow allows for user defined charging power limits but I haven’t tested it under a larger load.

I would assume that the additional draw when charging and having an AC output load is to be expected. I know that is how my EF stations run (I think my Bluettis do also). It is following two commands, pass thru to the draw demand, and charging the battery back up at the speed selected.

That makes sense that it wouldn’t you charger to power inverter when it’s plugged into ac. manual load management while charging??

If it was plugged into the utility it would be fine. When it is plugged into a battery powered inverter with limited kw, it is not desired.
I still think using DC might work.

The massive battery arrived today. Pretty cool to have a bluetooth battery. Arrived at about 30% charge.
My 35A battery charger is charging it up. I have the same one (Vevor) on my pellet stove. Still have to fire up
my 20A DC DC charger.

I think I can live with this charging limitation. Basically, if I set the DJI charging to "standard", which is 600 watts, then if it the DJI is simultaneously driving loads it's gonna try to supply those loads PLUS the 600 watts. So if I make sure to keep the loads below 500watts or so, it's not gonna make the EV-connected 1000watt inverter give up. If the sum of 600 plus the loads exceeds 1500watts or so, then it's not gonna pull any more; and if the sun is shining, the solar inverter can supply that 1500watts (the SMA SunnyBoy "secure power" output).
