My current system: Sol-ark 15K with 17.56kW DC PV and 600Ah battery bank grid-tied. It works flawlessly. I had a few extra modules laying around with Enphase micro-inverters attached. I got bored and decided to AC couple them to the Sol-ark as an experiment. The new array is only rated at...

Dumb question: Why limit it at all? Why not enter the maximum?

Once again, I'll post a screen shot of my 15K showing your problem is not universal. It is either a configuration issue or hardware problem.

Mine doesn't have any issue. I routinely see 17Kw PV, and sell back 16Kw. Today was a bit overcast, but still saw good production on my 17.64Kw array.

I'm just south of you in ID. Our inspector is requiring the same of our ground mount array. The guideline our inspector gave us is '6 foot chain link fence or equivalent'. We are opting for a simple 6' cattle fence around the array to satisfy the requirement. Seems the inspectors have all...

The single wire is 4/0, 445A. The jumper is 2/0, 330A.

I was wondering about that. My battery has a maximum discharge of 300A. As long as 100A goes to the second breaker, I'm golden.

Here is my solution to a single large battery, and the dual 200A breakers. A 2/0 jumper:

and, it is back up. That was strange! I didn't change anything.

How bizarre. Mine just did the same. No fault, however. The whole plant is offline, and the dongle is not visible by my router (also Starlink). Hopefully just a coincidence.

I thought I read that it was recommended to perform a factory reset after the latest software update. If that isn't the case, I won't worry about it.

There is a screen for performing a factory reset on my 15k. When I click enter, the system asks for a password. Is there a default? The manual doesn't mention it.

Much relieved! Thanks very much.

Thanks for the reply. Probably an hour. I'm thinking the BMS is probably not calibrated, as the battery is new. Maybe with a few charge/discharge cycles it'll learn the base voltage and SOC

I just noticed they have an new spec sheet published. This one has the charge voltages even lower! Back to my original question. Does 49.9V at rest seem unreasonable based on the charge voltage?

I can't over-ride any of the settings unless I unplug the CAN-Bus connection.

It is in the Homegrid spec sheet, and is what the BMS programmed the inverter settings to when they started communicating with each other

I have a new Sol-ark 15k and Homegrid 5-stack (500ah) LifeP04 battery. They are connected together with closed-loop communications. Charging voltage is set by the BMS at 53.2V. As soon as charging stops, voltage drops rapidly to 49.9V, but shows 100% SOC. Is that normal? I don't have a...

I have the same 15k Sol-ark. I checked this morning. There is a bus bar visible under the 200a battery breaker that bridges both poles of the breaker. Thus, they are paralleled on mine..... Did they remove it on newer builds?

I just read the link you shared. Yes indeed, it appears it is now manual. Too bad. Mine acts more like a transfer switch.

I have the same setup. Mine is an older IO101, so I'm not sure it is still the same. IF AC power is shut off, DC automatically takes over. If AC comes back on...I don't have to reset it.....it takes over. So a simple lamp timer works in your situation.
