I'm waiting for my 2 18Kpvs to ship. Does this mean I should change my order to this configuration?

2 18K's makes for a very simple setup and wiring, 2 boxes and 100A of AC output. If you like connecting a lot of wire and putting in bus-bars, and ... then by all means buy more boxes and hook them up. The more boxes you have the more complicated the wiring, but the greater the redundancy. So with 4 6K's, one goes down you have 75A , vs 50A with the 18K. Then again the more boxes you have the more likely one will fail. If you decide you need 150A you only put up one more box instead of 2.

I think you will always have fewer problems if all the equipment is the same, and you have fewer pieces of equipment. YMMV.

Well, a happy medium between 1 and many.

It depends on how flaky the equipment is, too. Hard to say with this newly released stuff.

An argument for having more units stacked in parallel is that, if 6000XP goes out of production (or the exact revision you need to stack disappears), and your system is exactly sized correctly at say 3 inverters, if one of those dies in 2027, you are screwed and need to either get power frugal to live within the means of 2 inverters, AC couple some stuff into the 18kpv, or throw out all the 6000XP and get new ones that can be stacked together. Other solutions to this SHTF are of course possible like posting WTB messages praying for a savior to sell you parts or inverter.

Whereas if you get say 5 inverters for a minimum of 3 to serve your loads (IE 2 spares), then if the inverter failure is random you'll have enough spares to make it a lot longer.

I fixed your typos for you.

I'll stick with simpler.

Wow thats a clean set up. Looks really good.

I did all the DC side a little at a time. I just got the last piece if the puzzle for the AC side (fused disconnect) and my electrician should be able to do that install in a few days. Then my beast should be ready for real life trials. Gotta have the AC work done by a certified electrician due to still being tied to the grid.

Are you using closed comms or open comms with those EG4 batteries?

I have yet to max out my 2 Sol-Ark 15ks and I have tried..

I’ve been able to have closed loop with either battery bank. Even though Sol-Ark support will always say they don’t support closed loop coms with EG4 batteries. They’re taking to each other for me no problem. But to clear I never connect bother banks to the inverters at the same time it would void the warranty. The rack is reserve power and I have Amphenol connectors on each battery bank so I can quickly change to my reserve bank if necessary. I’m hoping that EG4 can eventually work out the BMS issues soon so that I can connect all of them to the main bus bar all the time. I understand it is in the plans for the future. It would make sense.

No Warranty problem dont worry about that. The PP will not communicate with the Lifepower4s. You can use the together without comms but keeping your cells balanced is always better when the batteries can talk to each other.

Zapper has made videos using the 6kxp as grid for the 18k that s

Markus I’d love to believe there is no warranty issue using both PP and LL V2’s together but the manual says otherwise. And James also said that it’s an issue that needs to be worked out so coms will be functional between PP & LL batteries. See second bullet point under warning in PP manual.

I will get this changed as soon as the Firmware is ready for them to communicate

I'm going to try heat bending sch40 1.5". If that doesn't work I'll use flex.

A tip I picked up from my dad years ago: stick PVC conduit in or over a tailpipe until it's soft and then hand bend it.

I heat gun will do for smaller stuff. Don't think I've bent anything over 1".

timselectric · Dec 12, 2023

I have bent 2" with a heat gun.
It takes a lot of patience and avoid any breezes.

PS: closing off the ends helps.

I've done plenty of 2" with a heatgun, like tim says it takes some time, but it works well.

Can of pvc glue on fire ? works pretty well when there's no electricity!
Just don't start the fire in the bottom of the ditch ????

Nope. ?

You can actually use the LL S firmware now to achieve close loop if you have a 6 dip switch V2. I have the 4 dip switch firmware as well it’s just not posted.

After updating the V2s with the LL S firmware the V2s will also trip the breaker and bms if the rsd is pressed.

The power pro needs the update on the eg4 website for this to work with close loop only with the 18k or 6kxp

So I don’t need to update the power pros for my Sol-Ark 15Ks? I do have V2’s in my rack… so if I update them with the LL S firmware they can work with the power pros and have coms? How do I set DIP switches ??

Markus_EG4 · Dec 12, 2023

Only update the power pro for close loop rsd function of the battery with the 18k or 6kxp.

all you need is to update your V2s with the LL S firmware and they communicate with the power pro

The dip switches just set up according to the configuration 1-64. They are the same in set up

Just update the LLv2 with the LLv2S firmware, I think is what Markus_EG4 said.

Leave the PowerPro as is.

Will do… I’ll let you know if there is any issues. I should be finalizing my AC side tomorrow. Electrician should be here tomorrow at 3PM. Can’t wait to run test on my new monster
