If you are just planning on having PV panels and selling to the utility you only need to use the GRID terminals to do so. The LOAD terminals are for if you have batteries. Any loads you would want the inverter to keep alive during a grid outage would go on the LOAD terminals. However, if you...

Yeah Haha I'm here, I just get off at 6 pm Central time. Also monitoring the forums is more like a third priority to my other duties so I may be a bit slow to respond sometimes, but I will get back to you. I certainly hear the point you are making. The Sol-Ark checks every AC connection it...

Whenever you dont see the SOC or Voltage options in the Time of Use menu it is usually an indicator that you are in Closed Loop Communications (Lithium Batt Mode on the Inverter). We do not have closed-loop communications with the Soho telecom batteries so make sure you remove the...

I'm going to dig up some more information on my end so can get a decent response for all the points you brought up, but I will say I have seen many installations work in that configuration with no issues, but its certainly woth looking into for you especially if it brings some peace of mind on...

Not sure what you mean by Eco mode in this instance so let me know if Im not understanding. Grid following to grid forming happens all on the AC side so even if there is a set transfer delay the DC side would stay active the whole time. I don't think it would be practical to turn the DC side...

We do for certain have a default 4ms transfer time. The adjustment was added because some users wanted to be able to tell if there was a transfer happening as it was happening so they could change processes. Now if those changes were happening physically or some sort of operations change when...

Thats right. The Shutdown V or % indicates the battery level in which the inverter will completely shut down. The Low Battery level will highlight the battery icon yellow as a warning and is the lowest value you can set TOU to in the settings. Finally, the Restart value is for dark start mode...

Yeah, thats part of the hardware differences between the GRID and the GEN terminals I mentioned above. These hardware differences mean a 3-phase generator can only be input on GRID terminals though we try to clarify this limitation in the manual. The best setup for integrating a 3-phase...

The generator terminals on the Sol-Ark cannot differentiate between 120/240 split-phase and 120/208 3-phase connections. Our grid terminals have more hardware and sensors behind them, allowing us to connect and sync up to many different utility types. For the Sol-Ark to connect to a generator...

Good catch, this is correct. To avoid nuisance tripping please follow the 80% derating rule. My apologies for missing that in my post.

I cant officially recommend anything. I have seen plenty people use Midnight Solar Battery Bus bars. You could also use something similar to this : https://www.solar-electric.com/homegrid-hg-sol-ark-15k-busbar-pair.html

https://www.sol-ark.com/map/ I would also recommend a manual transfer switch between the grid and the Sol-Ark in case you need to isolate the Sol-Ark and still have access to grid power to your main service panel. You can connect any 48V battery to the Sol-Ark battery terminals, just be sure...

If the master inverter is consistently 0.4V off I can send a calibration command to fix this for you, but I don't think that is related to the shutdown and large voltage drop you saw. Sometimes the voltage sensors just read slightly differently. I'm hoping its just a one-off event, but as far as...

Are you able to catch the battery voltage with an external meter at all? I see you are using Solar Assistant which pulls from our ModBus readings. If there was a problem with the Sol-Ark voltage readings on the Master inverter, Solar Assistant would show those readings bad too. We would want to...

Send me your email and your inverter SN in a private message and I can take a look.
