Pytes or SOK

Trying to make a decision with little experience to help with the decision.
Using a sol-ark 15k, which battery would be the better choice, especially for support. The pytes battery sets it's parameters with the inverter and SOK parameters are set manually. Any insight would be appreciated.

I thought the SOK worked great with the solark. I'd give Current Connected a call or ask @HighTechLab to clarify.

Dose the Pytes battery have a heater?

I live in Phoenix AZ

The pytes battery have a UL9540 listing with the sol-ark which may help or be required for permitting, and code compliance.

Pytes Sol-Ark UL9540

I am leaning towards Pytes. What did you end up choosing

I'm still waiting for install to be complete, but I'm 100% going with Pytes E-Box 48100R. I'd like to go with their V5, but it's probably not UL9540 with Sol-Ark, at least not yet.

The V5 does.

The SOK is UL listed. Also- what swayed my decision- the ability to repair/ fix the system. Worst case something goes wrong a
Few years down the line- you can swap out cells.

Me as well. If you can’t swap cells (welded), it will be a huge pita.

• Certifications: UL1973 & UL9540A certified, UL9540 pending

Pytes support ghosted me after realizing I have a defective battery following trouble -shooting. Numerous emails and after no response I filed warranty claim, and... crickets. I turned it over to legal at this point. Caveat emptor.

I had a pretty good experience with Pytes support in November. I own eight 48100R-C Pytes batteries, which were purchased at different times and had three different firmware versions. To address this issue, I reached out to them via email, and they promptly provided me with latest firmware, a monitoring and updating software for Windows (which differed from the one available on their website), an instructions manual, and a WhatsApp number to directly contact an employee for live video chat assistance during the upgrade process.

During the firmware update, one of the batteries failed and became unresponsive, essentially bricking it. However, the support guy, guided me through the steps to recover and un-brick the battery. They implemented two fail-safe measures to recover the battery from firmware-related failures. The guy assured me not to worry and that they would honor the warranty in the unlikely situation that the battery will fail to revive.

I didn't need to test their warranty replacement process because the battery came back to life. What impressed me was that approximately a week later, the same support representative reached out to me via WhatsApp. He wanted to check if everything was working fine and if I had any further issues. I found this quite a nice gesture.

What BMS is pytes using? Pace?

I'm still planning on Pytes V5, just waiting for access to Eversource Power Clerk so I can update my interconnect agreement. Actually I have access to Power Clerk, now waiting for my first net meter bill so I can enter my new meter number into the system. No, the meter number they want is not physically on the meter.

I am in the same place with 2 sol-ark 15 Ks going in now, I like the SOK outdoor cabinet and the ability to repair it but it appears that closed loop comms stops when you hit 15 batteries and then you are forced to reverting back to open loop, seems like a real backwards way to do anything compared to Pytes where after 14 you add their hub and then you are good to like 96 or something like that.

Maybe there is a way to deal with more then 15 like using peter boards or something like that.. Ideas anyone?
