Up and running!

I don't have an EV yet but planning to add one in the future. I thought about this exact situation because yes, if the grid goes out and your 15K is powering everything, including an EV charger, it will continue to charge the vehicle and drain your batteries. Easy inexpensive solution... I...

A soft starter on the heat pump would probably solve that issue.

I am using a similar 200A breaker panel between the meter and solark instead of a fused disconnect. My inspector said it would be good to go. It'll offer the same OCPD as a fused disconnect and much less expensive. It will also allow me to add a branch circuit exclusive from the inverter. The...

Just when you think you got the latest and greatest, Sol-ark is now introducing a 30K and a 60K! https://www.sol-ark.com/sol-ark-30k-all-in-one/ https://www.sol-ark.com/sol-ark-60k-3p-480v-n/ Edit: it looks like they're for industrial use as they do not support split phase, only 3 phase.

I see, I misread your post. That does seem to make sense the way you sketched it out. It looks like adding a transfer switch complicates the hell out of it since you'll have the grid input/output AND the load output to contend with. I agree that just having a 200A breaker on the main panel...

Just updated yesterday. It was recommended by Sol-ark to do a factory reset of the 15K after the update. If you do that, make sure to take pictures of or record all of the settings you have programmed so you can set re-enter them after the reset.

Even still the 24kVA for 10 seconds surge is huge! 100A should start up a good sized central air/heat pump system.

Yes, 200A fused disconnect next to my meter. It was a requirement for the power company. I also put in a 200A breaker panel inside before the service entry cables hook up to the sol-ark. This gives me a grid disconnect inside, next to the inverter and a non-backed up panel for a future electric...

My utility (PP&L in northeast PA) pulled all the Sol-arks off their approved list until they fix a communication issue with the inverter. Not sure if it has anything to do with the California list, but they want to have some control remotely over the inverter settings. I have the 15K on the wall...

Yes I believe that's correct, just the high voltage DC needs to be in metallic conduit. Battery cables can actually be in free air.

"The Sol-Ark team will be taking pre-orders from distributors on Monday morning 4/11/22 at 08:00am CST"

I called Sol-ark with this exact question since their manual indicates the ground neutral bond at the main panel instead of the first disconnecting means. They said that they would recommend placing it at the first disconnect instead of what the manual says. So yes all the ground wires currently...

It looks like the one from the link I wanted to include is no longer available. It was a 10" wireway if you come across another one. I shimmed it out with a 3/4" piece of PVC but plywood should work too. The 3/4" spacer worked perfectly with the conduit knockouts on the sol-ark. I think I posted...

I would think that if you leave the ground bond at the main panel, then current on the neutral can also flow through the ground wire connecting the main panel to the disconnect (and through any equipment in between).

Good to know! I'm trying to set up a preorder with my distributor now.

After talking with my utility company, they said that the collar they would add to my meter would double as an A/C disconnect so I could get away without having one outside next to the meter. Other utilities may be different and require an blade disconnect next to the meter though.

Double check, but I’m pretty sure code is 6” beyond the front of the main panel, not 2, and 15” left or right from the centerline of the panel.

edit: double tapped

So in effect, would this make my main panel of sub panel of the first disconnect? I have 3 additional sub panels in the house, would that make them sub-sub panels? Is that allowed? The diagrams in the solark manual indicate a ground/neutral bond still at the main panel which is what makes me...

They wouldn't, other than seeing my power usage drop almost to nothing. Until PPL approves it to interconnect, I plan to hook it all up and run it in Limit to Home mode, so it will power all my loads and charge batteries but won't export anything to grid. It'll still be hooked up to grid so I...

Anyone have more information about this? I'm in a very similar situation. I currently have 2 Fortress eFlex, but would like to increase my battery storage. I was considering purchasing 6 EG4 batteries in a server rack and selling the eFlex batteries since I didn't think it was possible to mix...

Yes it would. The trough was kind of a pain to mount and line up all the conduit, but I did it once, I can do it again if I ever have to. Personally, I like the EMT conduit from the trough to the sol-ark for aesthetics, and using EMT allowed me to line up conduit on one end and let it "hang"...

As long as your DC is in metallic conduit of some sort, no. I used liquidtight metallic flex for my run from the roof to the basement.

Yes you can use the feed through lugs, that’s what I did. The 120% rule doesn’t apply since you aren’t using a backfeed breaker. Here’s a picture I took while finishing my install. The top of the panel is from grid. The 2/0 wires on the bottom lugs go directly to the 15K. EDIT: I see you are...

I'm currently running in limit to home mode while I go through the interconnection process with my utility. It uses CTs and does not physically disconnect so that it can still import power if needed. It will try to continuously pull in a small amount of power from grid so that it doesn't export...

Just talked to Sol-ark. They're saying June release date now. Still waiting on ULs.

PV Pro indicates the same 3kWh export.
