No longer selling -- 2x EG4 18KPV-12LV AIO Hybrid Inverters

[Millennium]

Hi All,

Sorry, but I'm no longer selling these:
2x (two) brand new (unopened) All-In-One EG4 18KPV-12LV Solar Hybrid Inverters. I just purchased these from Signature Solar in September 2023.

Inverter: EG4 18KPV Hybrid Inverter | 18000W PV Input | 12000W Output | 48V 120/240V Split Phase
Model: EG4 18KPV-12LV
SKU: 1602002
Link: https://signaturesolar.com/eg4-18kpv-hybrid-inverter-all-in-one-solar-inverter-eg4-18kpv-12lv/

The reason I'm selling is because I don't have room to install these in my home.
I'm now looking to buy a single All-in-One 3-phase inverter from Sol-Ark; I can fit one inverter, not two.

I'm trying to recoup some of my money and will sell at a discount.
Will take best offer, but please NO lowball offers.

I can deliver to anyplace in Southern Arizona (counties: Maricopa, Pinal, Pima, Cochise, etc.).

I don't ship. This offer is for pickup in Arizona, or you will need to arrange your own shipping.
I will try to facilitate any shipping arrangements as best I can (ie, loading, etc.).

I'd be happy to PM my phone and email, if anyone is seriously interested to discuss.

Thank you!

You going to 3 phase for your house?
Which Sol-Ark unit are you going with?

You going to 3 phase for your house?
Which Sol-Ark unit are you going with?

I'm thinking the Sol-Ark 30K-3P-208V, but I just discovered that I'll need a new high-voltage battery rack, which is going to get expensive.
I found one for $21K.

Sol-ark L3 30K-HV-40-IP20 Indoor Battery Bank

Note: This battery bank is intended to be used with the Sol-Ark 30K-3P.

That's $535/kW for the 3-phase inverter batteries versus $290/kW for the single/multi-phase inverter batteries.

I really like the Sol-Ark 60K-3P-480V, but the batteries cost anywhere from $30-40K for an indoor or outdoor rack.

Sol-Ark L3 60K-HV-60-IP55 Outdoor Battery Bank

Note: This battery bank is intended to be used with the Sol-Ark 60K-3P.

That's anywhere between $510-$660/kW. Yikes!!

Now I'm having second thoughts about the 3-phase inverters.
I may just keep the single-phase inverters.

You could buy individual cells then run them in series for the 520volts?

520v@280ah is like 150kwh.

Got to be a better solution than buying proprietary batteries.

There is a guy on YT who lives by himself in a trailer.
Has a ballast ground mount array.

Looks like he uses Jk balancing.

He also runs a High voltage inverter.

Edit:

Here is his channel. He runs 230 vdc.

Have you decided if you are keeping these or not?

Have you decided if you are keeping these or not?

Yes, I'm keeping them; high-voltage batteries for 3-phase inverters are prohibitive.

I'll just buy one more EG4 18KPV-12LV and update the firmware for 3-phase use.

Thanks for your interest.

150A / 50A x 3, should be an interesting project, should run a pretty fat load
