W@P's Solar System

So I had the same issue.
What is the soh? Check the lights on bottom of battery and see which one is not full. It could be batteries are not equalised and the master is full and telling the one to stop charging . Ensure master is the battery where the charge lights are lower
1. Ensure you have latest software update from Hubble. This was an issue earlier on in the year.
2. After update, switch system off and reset battery, hold the button for 6 seconds.
3. Charge battery to full, no discharge, means set schedule to 100%. Even when it’s hits 93, let it charge for a few hours and see.

If that fails then maybe few cells died.
 
So it charges to about 95% and then looks like a trickle charge till it reaches 98%-99% late in the day, strange.

I just noticed that my single Hubble also never gets to 100% when charged exclusively by solar and there is enough capacity to fully charge it.

From Solar assistant (seeing charge capacity as 95.8Ah) which doesn't look right (need to check on Inverter itself later)

may have to do some of the tricks posted earlier by @superskully in this thread

I had a similar issue, which turn out (to me at least) a calibration issue, it start from here: https://mybroadband.co.za/forum/threads/advice-needed-solar-system.1181190/post-29842563

Check that it reaches 53.6V

99% SOC

This is normal behaviour by design. Your batteries do reach 100% but then settle and rest at 99%. Our BMS reads 100Ah as 100 000mAh, if even 1mAh is taken out the battery, i.e. the batteries capacity is sitting at 99 999mAh the BMS will report 99...

Sorry for late reply. It does get to 100 if I set the SoC for the time to be 100 .. wierd (no grid charge enabled). Would have thought that even of SoC is set to 90, it would get to 100% if the capacity was available to charge it. Not really sure. I know I probably have to do a firmware upgrade on the sunsynk, but preferring not mess with something that seems to be working for the most part

I am still battling with my father's sunsynk also not reaching 100% SOC. Might do a firmware update and hope for the best.

I was having the same issue where my Sunsynk + Hubble seemed to be thinking that 88% = 100%. My installer recommended I do as in the pic.
I’m not sure if it was that or the load shedding forcing charge from grid only, or just coincidence but it seems to be resolved for now.

Jip have done that twice now already.
 
The neighbors do not have a prepaid meter for about 2 years now. Free electricity all this time. They have been begging the muni to install a prepaid meter that they paid for but muni used the funds for other ****. Now my power is off they finally busy installing a meter for them. I had the AC running, both geysers kicked in and the vacuum machine. Inverter tripped.

Mine tripped yesterday just after loadshedding started, geyser and dishwasher was on and the wife turned the oven on. Tripped at 9,3kW, then I switched the geyser off. Still need to get Solar Assistant to better manage this.

Mine used to trip about fscking everything, so I got rid of her.

Precisely why I'm upping to the 16kw. Got no interest in trying to balance stuff I use at home and worry about tripping.

Should be getting the new one installed in Jan, maybe December.

Will your battery discharge be sufficient though?

Most of my trips have been because my 9.6 kWh bank can only discharge at 4.8 kW (0.5C). Not an issue when there's power, but when there's load shedding or an outage there's a risk...
