Do you have the Gen Charge box checked and the Current plus minimum battery SOC set? (See Post #23)
Do you have the Energy Pattern set to Load First? If it is set to Battery First then it will charge the batteries until there is enough excess PV to supply the house.
How is your TOU slot setup for the morning?
Also under the Battery settings if the Battery Low or Battery Empty Setting are set higher than the 15% it will not use the battery in the TOU.
Robby, thanks for your input. I have read many of your posts and appreciate your support to the community.
I was hugely enthusiastic about the Sol-Ark before I purchased it. I am trying to remain optimistic that they will remedy these problems in a timely manner.
I currently do not have a net-meter so I cannot sell to the grid.
All four of the issues have been confirmed by senior Sol-Ark support. They are saying that the system is operating the way that it is programmed.
Yes, I have the "Gen Charge" box checked and the "Gen Start SOC %" set to 10% "Battery Low "is t at 5%. It I disable TOU, the generator will start, and will charge the batteries. However, TOU is required for my use case.
It was finally confirmed by Sol-Ark that the generator will not start if TOU is enabled. I'm running 7.2.2.2 firmware.
Yes, I have the "Load First" energy pattern.
My TOU settings are all the same: 15%, no "sell" or "charge" checked.
My working mode is "Limited to Load".
"Grid Sell" is not enabled.
Sol-Ark will soon be releasing "Revenue Grade CTs" so they are compliant with the ANSI C.12 standard, which is required by most states to receive the solar tax credits. The revenue grad CT's are not going to solve the problem if your inverter is wired in-line with your grid. This is because the inverter can push
produced power in multiple directions: To the grid, to the load and to the batteries. The Sol-Ark already measures PV production. They have alluded to me that the accuracy does not meet the standard. They haven't revealed in detail exactly what they are pursuing but it has something to do measuring the PV production at the MPPT level. I'm guessing either DC CT's or some other accessory device that would go inline with the MPPT's. I have searched but cannot find any ANSI C.12 compliant revenue grade metering device that would go inline with my MPPTs.
Prior to my purchase, I had several phone calls with Sol-Ark "Engineering Support" discussing my intended configuration, specifically the generator. It was never disclosed to me that my 22KW generator would not start nor would I be able to receive solar tax credits.
I have used "ladder logic" and written PLC code before. I have programmed in other languages also. I would have taken a different approach to the way that the Sol-Ark is programmed and configured.
