EG4 new AIO rated 12K output and 18kPV aka "EG4-18Kpv-12LV"

[rakitejada]

Hi. Quick question.

I saw @Will Prowse video that showed him adding a EG4 PowerPro battery to his 18kpv. He also said that you NEED to add two batteries at a time.

I have a 18kpv. Have 6 lifepower 48v batteries. And i need around 50% more storage for what the EG4 PowerPro battery fits perfectly.

So my question is: Even i already have a server rack of 6 lifepro batteries on the 18kpv, i cant add just one PowerPro battery?

Thanks

My understanding is that powerpro and lifepower have different configurations (15s for powerpro and 16s for lifepower). This results in different voltage profiles for charge / discharge. But I'm just a pleb, take that with a large grain of salt.

 

[Farm Boy]

Me too. For the cloudy days ahead.

 

[sburcham]

I’ll add mine too at 30 days of monitoring about 35 total days of use had a dongle issue. I need more of everything ha.

I see you have import reading and zero export. Are you using grid assist? I also notice from both of you the pv voltage is not shown but I'm still using first screen version.

I have mine setup as a critical load panel. I only turn on grid if my batteries are low. My Power company put me on the "wait list " for a "Interconnection Agreement". Once approved, if I even accept their terms...I'd need to pay the $10 monthly fee for a 2nd meter and a monthly $22 manual billing fee. Additionally the only benefit would be using the grid as a battery. (They pay zero cents per kWh)

the utility is pushing for approval from the utility commission to allow billing for distribution fees for all kWh pushed or pulled from the grid.

Example my kWh rate is 11 cents and distribution cost around 9 cents per kWh. With each kWh I feed into the grid, I can get back for free.

But if their request is approved I would pay 18 cents per kWh in distribution cost.) Their argument is the distribution network is being used but not paid for....so while the energy is free the service provided by the network of cables and transforms isn't.

Looks like 16s.

Our inverters could be paralleled, I have almost the same numbers to within 100kwh of solar and battery and 300kwh less consumption.

 

[Heritage1]

Just around 3 1/2 months here. Over 6Mwh solar and almost 7Mwh thru the inverter.

Very nice! Good do you have the generator hooked up?

No generator hooked up at this time.

But if their request is approved I would pay 18 cents per kWh in distribution cost.) Their argument is the distribution network is being used but not paid for....so while the energy is free the service provided by the network of cables and transforms isn'. I see on my bill examples similar to your explanation as on my bill shows 1 month supply being 2.08 and delivery 8.93 equal to 11.01 or another mo., supply of 7.75 and delivery of 12.68 equal to 20.43.I don't bother to complain just pay.

Critical load panel here as well but main is empty other than 3 circuits. I receive similarly explained bills where I use for say 1 month Supply charge of 2.08 and Delivery of 8.93 = 11.01 or another Month Supply 7.75 and Delivery 12.68=20.43 Not really fair but pay it as insurance to keep the grid use when needed. Your situation looks like their coming up with ways to comp some of there overhead but if you except it you'd be legal to use or feed back grid and use it as a supplement. It would be great to use the 18kpv to it's full potential with all it's bells and whistles but is still a great inverter even if used just off grid.

Folks, you cannot call Deye and ask them to private label an inverter for you in the USA. that may be limited to SolArk. I believe you can call Solis, Growatt, Luxpower and some others and they will private label you an inverter.

So maybe the forum should have a design your ideal inverter thread. Set the final specs and get people to commit to buying it and doing community support. Savings could be in the thousands.

Let's start: Inverter Output AC 240/120 sizes 8k, 12k and 16k. Parallel up to 3 inverters (equals 200 amps). Built in ATS, generator support, high voltage and low voltage battery support, 4 MPPT's at 20 amps each up to 600 volt DC input. Max PV input equals 36 kW. AC coupled too. Breakers included, wifi and cellular dongle. Included 120 amp or 180 amp battery charger, NEMA 4, convection cooling, floor mount or wall mount, full software support, all other standard certifications and features such as UL1741, CEC compliant and, UL9540 and rapid shutdown.

If there was a commitment to 1,000 units of these, the price landed would come in at probably 3K or less. Sort of like an inverter kickstart.

This kind of project means larger heat sink, MOSFETS, etc. But nothing that is not already being done in the larger 3 phase utility and commercial inverters.

FWIW, if you want to UL it then you need to focus on a single configuration like 16kW to keep the cost manageable. The UL littany is about $100k per inverter all-in (maybe only $80k for UL of subsequent models on the same platform).

Honestly though the EG4 18kPV is close enough for me. What is a much bigger challenge to me is the battery situation. I want a 60kWh single forklift box with integrated everything that is designed to go in a residential garage (ideally without fire sprinklers). I want something that the fire inspectors and the city can't complain about since it is a UL box listed for the application.

Good point

You are going to have to commit to at least 100,000 units to even attempt to talk to manufacturers.
The EG4 18k and Solark 15K and clones already have 98% of all these features covered.

 

[G00SE]

Sigineer makes a unit with the specs I want. You just have to buy 10. And then there’s the reliability issue.
Ideally I don’t want something new to market. I want something time proven.

 

[G00SE]

This should read as “some firmware iterations have 98% of these features functional”

UL 9540 limits you to 20kWh in a single rack. Doesn't make sense to make a large box for 3 racks that are 3 feet apart.

By rough calculations, you could have a Nema-12 box about 30" wide x 18" deep x 76" high that integrates 60kWh of battery (64 304Ah cells), inverter electronics from an existing design, all the needed circuit breakers, and bypass breakers (actually a panelboard if it had side access) in a separate compartment. If you wanted to make it stackable for battery or inverter there are a few elegant ways to do it while limiting field work.

Sure, it would weigh about 1,500 pounds, but with labor as sparse as it is I would have to think it is worth more than the sum of the parts. This is why Tesla's new Powerwall integrates much more in one package.

I thought there was a path around that for LFP, but there are still some inconsistencies between NFPA and UL. The key as I read it was that it be listed as a single unit and tested in accordance with 9540A.

Almost 2 months in and very happy with the results, over 3000kWh in Solar Yield and over 4000KWh of total consumption.

I only have part of the house connected and still not approved to feed the grid so i am losing a lot of kWh daily after the batteries are charged and i have topped up my EVs, once i get approved to feed the grid i wont lose a kWh of power and the Solar production wont be limited, those numbers will go even higher.

And this thing is a beast, look at how much power was being drawed yesterday (with grid assist) and it handled it like it was nothing (well, ignoring those noise of the fans ?)

Love my system

Thanks @Will Prowse and @Gavin Stone for your videos, you were the ones that convinced me early on. Best choice ive made for my home
