I am looking to add a manual transfer switch before my main panel so I can back feed power to my whole home in the event of a power outage. The 200A utility would connect to the switch, which would then connect to my main panel, and to my Sol Ark 15k. By default I would have the switch...

Quick update on my issues: CTs were never installed Anti-reverse function was enabled, but my understanding now is that this function requires CTs to work properly I disabled anti-reverse and things started to work as expected both on and off grid I'm now discussing where to place the CTs...

I tried the hose idea! Even standing on a ladder, I couldn't reach them with enough water to make a difference. My roof is actually quite steep. On regular snow days, it does tend to slide off on its own. We recently got a dumping of 25-30" so they didn't see the sun for over a week...

This is very interesting, hadn't considered it. Time to do some reading!

Yes. Yes. And what happens when I need to service the inverter? Did you read the post?

The dashboard values are updated every 1-2 seconds, so SA is definitely receiving this data. This includes AC load, battery load, PV, and SOC. The charts for these values only offer data points every 10 seconds. No mystery here!

almost :D no problem, it's the reality of working with such a poorly documented unit

Load 2 is for 'unimportant' loads. The MR will shut that off when battery is not sufficient. All critical loads should be connected to Load 1.

With solar assistant I see no need for the app. What benefit would it provide? Yes, exactly. Again, this is not the job of the Pi. This is handled on the client - your computer, phone, tablet, whatever.

I think this comment is the real reason SA has value. Unless someone has already done this from Sol Ark into Home Assistant, it would likely be very time consuming / complicated to do. I'm plugging this into the Pi today so SA can get more details about my batteries. I hope it's the right...

I noticed this browning on the neutral coming in to my main panel. Maybe an indication of an issue? Would this connection point be considered the service entrance?

Hey everyone thanks for posting all of this useful information. I received updated firmware from Megarevo today. The zip does not contain an installer so I am waiting on that, but you may be able to use the one from page 9 of this thread. I'm not sure what the DSP version is, but CPU version...

I tried a different W10 machine and it worked o_O It would be nice if return is not an absolute value, but relative to the grid status. For example: grid discharge = 80 off grid discharge = 95 return = 20 grid discharges to 80, then charges to 60 (40 SOC) before discharging again off grid...

CTs corrected alot of similar problems for me. How did you disable them?

Where'd you hear this? I spoke with support who could not confirm. I find it very annoying that they will not publish any sort of changelog for their firmware updates.

My inverter shows all values update at once, and I would assume it's sending those same values to the logger, just looks like an implementation issue. The dashboard does not update all values at the same time, making them appear to be incorrect. Why would you want 10 second logging? Why not...

Maybe a dumb question, but during the meting process, would it help to shutoff the incoming PV?

Might have to, although I'm in touch with them so I'll see if it's possible to add a user-defined setting to control logging interval.

I've called 15+ electrical companies and nobody is able to help. Some get scared off when I mention solar, others have no idea what hardware would be code compliant aside from expensive auto transfer switches. Regarding the interlock option, I am not able to find something off the shelf, nor...

Are you suggesting i take my own voltage readings and compare against the voltages reported by BMS? Or is the info I posted above enough?

Over the last hour or 2 the top/bottom batteries now have the highest current in the rack. Does the BMS have control over how much each battery will charge / discharge based on the load? Or is it all up to physics? Any guess why the top and bottom seem to always have a very similar current...

Good point. Much less likely to burn out components, easy to automate. My panels Voc is around 47, I'm guessing I could branch off my 48v battery rack to the PV..how do you plan on applying voltage?

on the left is array 1 and 2 before upgrade on the right is after peak current went from 8a to 0.8a

The historical data provides the real insight into your system. Unless you're staring at the dashboard all day, the charts hold the real value. From their website, very misleading: It is already being polled every second by the logger. The issue is that SA is not writing those values to the...

Can you try a return of 20%? I think that value needs to be higher than the discharge value. So it will discharge to 60 soc and charge to 80 before discharging again.

I have 6x Jakiper 48v 100Ah in a server rack. Originally 1 set of 2/0 wires in a diagonal configuration on the bus bars. Now 2 sets of 2/0 wires in a square configuration. In both cases, I have considerably less charge / discharge current on the top and bottom batteries. Batteries all...

Yep bus bars, my wiring config is described above ^^ I find it interesting that from 100% SOC, the top / bottom have lower current, but later around 80% SOC, they have higher current. Voltages are so similar so I would guess the BMS is involved in this but I really don't know what I'm talking...

This one is from today, where I reset the pre-inverter PV breakers a few times. Each time I would get a brief moment of expected power output (<30s) then back to garbage.

Currently, if I enable solar input AT ALL, I will draw <10W for about 1 minute then the inverter will RESTART itself. This continues until I shut off the PV breakers.

225A main with a 40A breaker to inverter grid. 60A sub panel on Load 1. Everything seems to work as expected if there is no power coming from grid. When grid is enabled, PV throttles and battery is always charging. Grid and Off Grid DOD both 80. I'll try upping the return to 50 but you can...
