  • Post in thread: 5 ton AC technology with Sol-Ark 15K

    Thanks for the quick input so far. I'll just reply to this one but give some additional info mentioned in the other replies as well. Great info and insight thus far. For the setup of my house, I do have a ducted system and will continue with that infrastructure, at least in this house. My layout...
  • Post in thread: New Sol-Ark 15K and SOK rack of batteries.

    I just installed the same hardware. The SOK rack comes with 4/0 cable from the top and bottom batteries as you stated. I ran the 4/0 to a (4) - 3/8" stud bus bar, similar to the one Current Connected sells. They are perfect for DC voltages. Then from the each bus (+/-), I ran a pair of 2/0...

    Hi Bob, Thanks!, Just sent a reply as your post came in that talks about some points you mentioned. Before solar, my electric bill was only $140 with 10 tons of AC. Now it is $0 but still have to pay the $21 connection fee for the grid connection. What equipment are you using? Is it ducted? I...
  • Post in thread: 5 ton AC technology with Sol-Ark 15K

    Hey Robby, sorry for the confusion. The SA has only been running since Feb and since the weather was nice then (during commissioning), the SA has never run either 5 ton unit. The newer AC has 5-stages and slowly ramps up so I think it would be okay running that one during a power outage. That...
  • Post in thread: 5 ton AC technology with Sol-Ark 15K

    Since I already have great insulation, I think other factors, that are considered when doing a proper load calculation, come into play. Location, size, shade, windows, etc... I found this site that lets you do a rough estimate by taking those items into account. I would love to do less than 5...
  • Post in thread: Sol-Ark 15k will only invert 13k of DC PV to AC

    I'm just getting started with solar. I have the SA 15K with 11.2kW (28-400WREC), and 6-100ah SOKs. I'm not getting the clipping Clint is seeing, but I do think my system is throttling my PV Grid sell back. So I think it is similar although, not exactly the same. This seemed relevant for this...
  • Post in thread: New Sol-Ark 15K and SOK rack of batteries.

    Thanks for the kind words. BTW your picture did not upload it seems. I gave direction to my solar installer. He had not done a 12" trough before and was hesitant. His electrician that actually did the work loved the idea since you could do the conduit straight into the bottom of the SolArk...
  • Post in thread: Sol-Ark 15k will only invert 13k of DC PV to AC

    Yes, lots of options. Any best guesses what to look for? Going through all of the default views for Input, Output, Battery, Grid, etc... didn't seem to have anything outside of the params and I would have thought when it hit 10,000 earlier in the day, that would have triggered a response versus...
  • Post in thread: 5 ton AC technology with Sol-Ark 15K

    If you were trying to plan for a grid outage in FL and have a Sol-Ark 15K, 30kwH battery bank and 11.2kWh solar, what would you look for if you needed 5 tons of AC? I currently have 5 tons upstairs and 5 tons downstairs. The upstairs unit will need to be replaced and I wanted to start...
  • Post in thread: Sol-Ark 15k will only invert 13k of DC PV to AC

    I made an adjustment to my Max Sell Power this morning based on @Spunky post. The jury is still out but I think I got the full power out of the PV today. No clouds today and the curve is smooth with no dips. I'll keep watching this as it didn't have over 9kW at any point so I'm not sure I hit...
  • Post in thread: Sol-Ark 15k will only invert 13k of DC PV to AC

    I talked to SolArk and they are aware SOK is going through certification to have official closed loop communications with them. The tech recommended for now that I turn off CLC and run open loop for now. He said to note the CLC settings, then turn off BMS and adjust settings with voltages, then...

    @Spunky Here is my system work mode. Of note...I am grid-tied with batteries and selling back. I have 11.2Kw of panels.
  • Post in thread: Micro-Air Soft Starter on 5 ton AC? Variable speed AC vs Single-stage

    In the posts I have seen, they mostly seem to top out at 4ton AC units. "Regular" AC that kicks on with a very high LRA benefit greatly with a Micro Air Soft Start (SS) device. I'm assuming they are single stage. I have two 5 ton AC units. The older Trane unit (using R22) starts with the usual...
  • Post in thread: Sol-Ark 15k will only invert 13k of DC PV to AC

    Update: Well it doesn't look like the change to the Max Sell Power worked. :( Today we had some scattered clouds so the gaps before 1pm seemed explainable, but then the PV dropped to a few hundred watts for an extended period and the sun was bright. It had even gone over10,000W earlier with no...
