Ended up getting this power station because the wife didn’t like the name of the Oupes I listed . That was a flash deal at Amazon and apparently it has now expired so what we got ended up being $130 more for just about the same specs.

$480 with the coupon applied. I don’t argue. She’s in charge of the money.
No real reason to post about these except it goes to the point that I believe it’s better to get multiples of smaller tools like these and generators that one large unit. A 4100W Eco-flow power station on sale is $3100 dollars. You can buy 4 of the 1000W stations for less that $2000. Same amount of storage with four separate inverters and other components. Only thing is you can’t get a full 30amp outlet with the smaller ones. All of them can be hooked up to PV panels. Most of the smaller units can be fully charged in an hour. Some take two hours. Still, while you are running your wood gas generator, which usually is putting out way more watts than you are using, you can be charging these power stations and storing enough power to run your appliances through a day. All of the Lifepo4 batteries in these units can be charged and discharged everyday for about 10 years. One your power stations get up into the 100w range you can couple them with separate, much cheaper Lifepo4 batteries and double or for some, quadruple the available usable capacity.
Dont buy those pre built units. They are a waste of money.
Get this first. this is the heart for generator to battery storage.
You dont have to spend a fortune on an inverter anymore. These cheap inverters work just fine and these Reliable brands are very good and efficient.
Then for your battery just get a 48 Volt LifePo4 battery off Amazon. Never ever use lead acid batteries for any off grid system. They will not last, everytime they drop bellow the nominal voltage and charge cycle that battery your are destroying it. They wont last you a year!
That right there is 5 kW storage system with a 2.5 kW inverter and a charge controller than can charge up to 20 kW or more in a day. All for less than $1500 bucks. That is dirt cheap for that much capability.
Yup it’s impossible to beat the 5 kwhr lithium server batteries which are just so cheap now… The certified name brands are pricier but not by much. Even when dealing with cold conditions it’s now cheaper to provide heat to the battery then accept the reduced capacity of lead acid… That is a fundamental change in the last 2 years …
If you’re already ordering a chargeverter from Signature Solar, I recommend their rackmount battery, it has CANBUS and will talk to the hybrid all-in-one inverters, should you upgrade to that eventually. About the same price, $1000-1200. If you get six batteries they’ll throw in a nice cabinet to store them.
I have two of them already. They are awesome!
I’ve been quoting the Pytes V5 for my orders… virtually identical, but with built in heater which I need most of the time (not sure if the EG4 has that or not). $1600 on signature solar’s site Pytes V5 LiFePO4 Battery Pack
They are the one my supplier carries and I can get local supply.
If you want to DIY, price of prismatics are below two years ago now. It is possible to build a 15 kWh under €1000 now. Just sharing
Joep, this is good information, do you have any links from battery providers?
i think we made a good deal. Cant find them anymore. Sold out. This is the site.
It is China import of course, the only country in the world that produces instead of burrying people under paperwork.
We paid €55 for a 315Ah Envision. A friend pointed this and my flesh is weak. Couldnt resist.
But still they offer nice prices. It doesnt pay to buy in China.
Victrons are dropping too. And Victron has the Multi RS Solar now.
But I stick to the Sun Deye. I think it works best for me. I am not a programmer.
Edit. Here they are.
Joep, now I won’t leave you alone with questions…
What DC voltage do you plan to connect the batteries to, is it 48V?
What about the BMS and the 3x380V inverter? What are the prices of this equipment?
Thank you.
I follow Dala the great on YT. He works with HV used Nissan Leaf batteries. Another friend of mine is building such a system. Almost plug and play. Batteries are really cheap. But HV and me is a bad combo.
Then this deal came along and decided 48 V is my path. Already got a Victron system running and with the last change of panels last year there came a Sun Deye hybrid. Cost €2000 last year now €1650. Victrons are in the garage next to the car. Three Multiplys 2, three phase system. Sun is the same power 12 kW but only one inverter, Victron is 5000 VA a piece. We need 25 or more kW so that means 9 Victrons. To much and Victron recommends a proffesional to paralel the Multiplus. So, not my choice, way out of my comfortzone and way to big.
Sundeye is real easy to parallel. 12 k version is the biggest LV system available. 15 k is coming

48V is a very good voltage and generators - alternators also have this voltage, with which we can directly power the battery.
Wow, 11 kW! That is the minimum power I am looking for. We need 100 kWh or more per day if we are cutting all day. No problem during summer but in wintertime.
How is voltage regulated? I think LFP does best with a floating around 54 V. Have to get into it again, my brain is to small for all the projects.
Tone, if you have big 240 to around 25 volt transformer gathering dust somewhere,
there is a really cheap way to convert 48v DC to 240v AC, true 5kw of power.
30-40 watts of idle consumption.
for continuous 5kw, weight of the transformer must be around 40-50kg.
Joep, I once had the cover off my main electrical panel with some thought to making adjustments.
I looked at the chunky bus bars and the beefy main breaker and immediately broke out in a sweat.
I took that as a sign… screwed the cover back on the panel and called a proper electrician.
High Voltage (Or high amperage in this case) is no joke.
Yes, it is. Thanks. Made enough sparks with two 48 v batteries. Now I can laugh, with HV there is no second chance.
with dc there is no second chance. Part of the reason for the slow 50/60hz ac pulse is to give you a split second to drop the wire. Don’t try it, but as long as the path doesn’t go across your heart ie from hand to hand or hand to foot, it won’t stop your heart.
I like to experiment, but I’ll pass on this one.
When I was a kid, my uncle had all kinds of wonderful surplus electronics. He had an old communications receiver that was mostly used as an AM radio. The audio output was for headphones, but fed a vacuum tube amplifier and homemade speaker enclosure. One day I grabbed the phone plug and phone jack to disconnect the amp. When I them apart, one in each hand, I was able to discern a ground and power (or high-voltage dc, I don’t know) ummm, fault. One arm over each shoulder, hands behind my head, I tried to let go, but couldn’t. Most embarassing. Gave it one final try with all I had, and was able to throw them down. Great evidence of the grace and mercy of God. Didn’t stop my heart or brain, but it wouldn’t have taken much longer. I wouldn’t take much comfort in the zero-crossings of 50/60 Hz AC, 120 v or more.
Well, some would argue regarding my brain 
When I was installed industrial paint systems we had a six pack of welders ganged together and running on 440V. The whole thing turned on with a big breaker that had gotten broken so that the metal pole inside the plastic was exposed. We had been turning it on with a piece of wood but I got distracted and grabbed a little piece of conduit. Touched it against that metal pole and everything went red inside my head. Knocked me out for about 30 second. Woke up to find a bunch of worried faces staring down at me on the floor. Got up and went back to work.
That explains a lot about you, Tom
