Solis inverter settings

Question Please.
I connected my DIY Seplos battery to my Solis Hybrid 5kW yesterday. All was working fine.

Last night I was adjusting the settings so it would charge the battery at night. I was winging it mostly and accidentally set it to off-grid. In a momentary panic, trying to restore to self-use, I hit “reset” on the data logger. I managed to get everything working OK, except the inverter was showing as offline on the APP. I did a 15 second data logger reset this morning and both inverter and data logger are showing offline. The inverter and battery are working fine otherwise.

What do I need to do to bring it back online? I’d like to see what’s happening especially since the battery just got installed.

Current view.

This is done physically at the inverter, yes? Thanks. I’ll try that later. What stumped me is the logger was connected last night, but the inverter wasn’t showing. Otherwise I’d have put it down to a wi-fi connection or settings issue.

What I am noticing is the orange "net" light is not staying lit. It is fast flashing for a couple of seconds and going blank for a few seconds before trying again. So it is not communicating with the inverter. The red power light is lit and the green Wi-Fi light is lit. No luck finding an answer online, so have emailed the installer to see if there is a solution.

Do these loggers fail often?

Is the zappi connected 'outside' the CT clamp for the grid, ie - connected to the main esb box before the connection to the consumer unit ?

That makes sense, the solis clamp isnt seeing the electricity flowing to the zappi. Not certain if possible, but you would need the solis CT clamp to be before the zappi connection

Query on the overcharge SOC, my understanding was this is the limit as to which the battery will discharge. Self use mode is on and. I have my overcharge SOC set to 15% with the force charge set at 10%. However my battery is currently at 10% and as of right now the load is .301 with .259 coming from the grid and .041 coming from the battery.

Shouldn't it have stopped discharging at 15% or thereabouts?

Ah, just read back over my post, I had meant to say my overdisharge SOC is at 15%.

I monitored it last night and it didn't drop below 15% so not sure what was happening the previous night. Maybe because I had just made the over discharge SOC and force charge updates and they didn't take effect until a refresh or something.

I haven't looked at what my overcharge SOC is, what's that do, the max the battery will charge to?

The inverter does some funny things. I've already had a couple of head scratching moments and it's only in recently.

The overcharge SOC will stop charging the battery once it reaches the percentage of charge set. More important for Li+ than LiFePO4 batteries, the former not being happy at high charge rates for any period of time.

Is it at 100% when this discharging happens? Battery's don't like to sit at 100% so the BMS will discharge a bit and then recharge over the course of the day.

My Solis does that 0.027 trickle from 100% lots of the time too.

I have a S5-EH1P5K-L inverter, 4.3kWp of PV panels and 5.3kwh battery, EDDI, and notice that every​ night between midnight and about 6am there is a 15%-20% loss of SOC (see graphic) from what appears to be a constant 100w drain
increasing two or three times to a 230w drain - even though there is no load​ from the home and minimal power is flowing to/from the grid.

Is this normal? what are other people getting? Installer saying that some battery charge/discharge is needed to keep the battery "awake" - 800w over 6 hours seems unlikely? what should the inverter use when not actually doing anything?

There is always load it's just the app doesn't show it below a certain level.

If the battery is set to charge until 8am it shouldn't kick in at 7am. That's unusual. I would check the settings again. Do you have a discharge rate set by any chance? Just for example I charge my EV between 2-6am and my battery is set to charge between these hours also and even if it is fully charged before 6 it will not kick in and start charging the car. So it should work for you. I have the same inverter.

Ok so check again. Time on inverter is correct, but it seems that it had changed the time of grid use back to 6am somehow, Ive reset it to 8am and I'll see what the morning brings. Thanks!

So, an update, didn't discharge this morning, think the time setting being changed back to 8am did the trick, charge/discharge slots set 00.00 to 00.00 too
