I have had nightmares getting inspection passed with anything. How do EG4-LL v3 with rapid shutdown that my inspector is demanding work in closed loop with SolArk 15k?
EG4-LL v3 and SolArk 15k

They want a Battery rapid shutdown not just a breaker?
Or
Are you talking rapid shutdown of the PV panels?

Rapid shutdown from battery separate from RSD of PV. Like EG4-LL v3 offers. It’s almost like his demand was word for word from what they offer.

Apparently being demanded by a few jurisdictions now, basically triggers the shunt in the breakers in the eg4 ll v.2, along with depowering inverter and solar, when rsd button is pushed

Any idea how EG4-LL-S battery work closed loop with SolArk 15k. I am about to order.

From what I understand a bunch of folks go with Pytes as a "preferred partner" for solark and easy California approval but unsure if they support estop:
Pytes V5 UL9540A 1C Battery ~ Current Connected
The Pytes V5 battery is tested and certified to UL9540 standards and can do closed-loop communication with any Sol-Ark inverter. This server rack battery is a preferred partner for any Sol-Ark inverters, meaning it has been tested thoroughly to ensure that it functions as expected...

Need to check with local authority prior to purchase.

Ya it’s Texas and he said ok on EG4. I will look into the pytes be he is demanding the estop come from battery manufacturer not something I run. 
he has been a nightmare it’s like he us forcing me to use that battery

Can you just get one rack mount to satisfy his madness and then install whatever you like after approval is granted? Almost need a floating llv3 to send around on perpetual tour for this kind of thing...Ya it’s Texas and he said ok on EG4.

is pytes that much better than the new EG4. Or are you saying I won’t be able to run closed loop with the EG4 and SolArk ?

The Pytes v5 is UL9540 compliant in combination with the solark 15k, I don't believe the eg4 batteries have been tested with the solark, only with the eg4 18kpv

Oh great, they are not 9540A? If not I will lose 3ft around them in my garage.

Never mind I see they are 9540A. I will call them about estop if I can find a number. Today.

The eg4s? Yes they are 9540A, but not 9540 when combined with solark.

Ok you’re right and that would been an issue. Do you know who I can call about estop. I want to get 16 of the v5 pytes

@HighTechLab (Dexter from Current Connected) would prob be the guy in the know

Thank you doo much. You saved me from being forced to either return EG4 or replace SolArk which I wouldn’t have done. It’s so weird my inspector is trying so hard to force me into something piece by piece. This nightmare started 2nd week of February.

I'm looking into this! Please stand by and I'll see what we can do.
By the way, you don't need the 18k inverter to use the shunt trip. Two pins of the communication cable are what triggers it - I'm not sure if they need voltage applied on these pins or just connected off the top of my head. I recall pin 3 & 8. That said, since Pytes is UL9540 with Sol-Ark that would be the better choice for this application, because the AHJ could require UL9540 in the future.
