and the other big annoyance is the portal often hangs so you can't check to see what your or your client's inverters are doing. for the last 90 minutes no info from the portal. There must be a way to monitor realtime, except for connecting directly to the wifi dongle with your phone and choosing local mode. On there you can see whats going on in real time and even change parameters. Some smart guy should be able to write software that can draw out those figures and make it available on pc.

Don't have the portal hanging issue. Mainly using the Solarman Smart app. 

I'm still waiting on the firmware update but decided to check the settings under local mode and found the always on setting under smart load. Turned it on and will monitor it over the weekend. 

Cool, yeah had to log into it that way also this morning, portal only came back online around 10:30. I think they have internet issues or server issues. Its a generic portal that a lot of inverter manufacturers use. If only sunsynk went their own way and used a seperate system it might have worked better, but it seems everything is outsourced. The guys doing the firmware either have no clue or don't understand what the issue is.

Don't hold your breath with the firmware. I requested mine days ago and followed up a few times with no reply. Support seems useless. @Johann1982 can you explain how one can get access to the portal and access local mode?

On the Solarman Smart app there is a local mode option. 

 

Connect your phone to the data logger's WiFi AP then it will connect directly to the logger. 

@HeindsYou do it on your phone with the solarmanPro app. Open it, tap all and LocalMode should be on the bottom. Use the box the wifi dongle came in or the wifi dongle itself and scan the QR code and connect to the dongle's AP. From there you have access to it.

Anyone else having issues where the inverter does not show SOC properly? My batteries are at 48.5V yet SOC shows 100%. 4x Pylontech, all dipswitches set to 0 and connected to RS485.

So that did not work and about an hour into my monitoring the aux load restarted. 

I then decided to do another test. I set the aux off and start percentages both to zero. I now noticed that it does restart but very, very quickly. Too quick for the Geyserwise to notice but my aircon just gives a beep now which makes me think it might be an issue with the battery and how the BMS communicates its SOC to the inverter. 

The smart load is still monitoring the battery SOC even when set to always on to determine when it should switch on or off. The pylontech bms might just be losing connection briefly and then the smart load resets. 

Obviously setting the smart load start and off to zero does not help as I don't want my aux loads to run when the battery is below 35% as my 3kw geyser element will deplete 15% within an hour putting my battery at 20% SOC.

I had the same issue and moved it to CAN which now only reports on the full battery bank and not reach individual battery.

@AchmatBut does that not limit what you can see on the batteries? Can only shows the bank as a whole... Not individually.. Not that I would make any real difference once they balance each other out.. But does it show proper SOC at the moment using CAN?

@Johann1982

Can we maybe get this thread moved to the inverter section as it might be a useful general thread on the sunsynk 8kw inverter. 

and did you have to change any settings on the dipswitches?

Do I do it or can Admin move it?

Yes it does but I'm ok with the BMS managing the individual batteries in the bank. 

With CAN, the BMS now also limits charge and discharge rates based on SOC instead of the inverter controlling charge and discharge rates. 

I have 3 x 3.5kw pylontech batteries so max charge and discharge rate the BMS sets 111A.

In the screenshot you can see that the BMS is now limiting the charge current to only 22A as the battery is above 95%.

All dip switches are down.

I'll report the post and request it moved to the inverter section.

Great, will give it a go

Thanks!

@AchmatOk, changed to CAN and it seems to handle the batteries better. SOC is showing properly now.

So none of the settings seems to resolve the restarting issue and I don't think the firmware update will fix it. 

Going to get my electrician in next week to move the aux loads to the normal load output. 

Was going to eventually use the aux load for some micro inverters in any case so resolving the aux issue is not a high priority for me right now. 

Just a pity, because I have marketed 3 of these inverters under the presumption that the aux load can function as it was supposed to. Not sure if Sol-Ark has the same issues, still waiting on a reply.

Pity we cant get Sol-Ark in SA. Their support is top notch and their youtube videos has helped me with many Sunsynk questions.

@Johann1982

 

Did you do the earth bond on the sunsynk inverter? 

I haven't done one in mine yet. 

@AchmatNo, didn't do earth bond as I have tested it as is and even in off-grid mode my ELU's work. I think it does an internal bond also, the relay with the earth bond is just an extra precaution. 

Solarman portal also hanging again this morning
