So far yes. I have not seen a spike in the charging from solar since. At the same time, the SOC has not dropped to 51% since the initial event.

It subjectively appears that the battery appears to be perfoming better - the yard stick being the SOC when the MPPT switches of and then when it switches the following morning. There are many variables overnight. This also does not exclude lifestyle changes to try and ensure that when the MPPT switches of, the SOC is 100%. I am comfortable with an 80% SOC at about 06:00.
Pre‑firmware (01/05/2026 → 01/06/2026, 32 days)
Avg SOC at First (morning): 72.8%
Avg SOC at Last (evening): 89.0%
Post‑firmware (02/06/2026 → 16/06/2026, 15 days)
Avg SOC at First (morning): 82.0%
Avg SOC at Last (evening): 92.0%
Delta (Post − Pre):
Morning SOC: +9.2 percentage points
Evening SOC: +3.0 percentage points
The chart below does not contain enough data yet. The blue line is when the MPPT is "Active" and red is Off.

Trust that will solve the issue.
Looking at your log, the big jump was from 51% to 78% in 1 minute. With that size battery that is virtually impossible.
I would run that battery down to shut off and then do a full recharge. That should reset the SOC.

Although at times your system might be playing up the above yields look quite ok for the panels you have. Today is a very bad day in Centurion.

I don't wish to get into an argument, but neither of the sentences quoted above points to the presumed anomaly of a sharp rise in SoC within a few minutes - in fact, I am still not sure if the rapid increase of SoC is what you are actually asking about... You will really get proper answers/feedback to your posts if you state clearly what you are inquiring about.

Hmmm.... one can currently get new 10/8s for not much north of 40K.

The inverter can't handle this really. Charge limit for the hardware is 100A, and the Goodwe agents won't set it past 80A as per - they say - an instruction from FreedomWon. Though if the hardware can't go past 100A, there's not a lot more that can be done. The bus bar is the main piece of the puzzle though. Batteries connect to this, and the bus bar feeds the disconnect. The two batteries would have to talk to each other as well.

FW want a minimum distance between the batteries, so I need to measure to see if I can meet that requirement.

Denns, your observation is correct.

Not to be that guy but 40k seems a bit high when you can get a new one fo 46.

Very long story about the 5kWh Pace BMS FreedomWon E tower and the rest of the lite family. The E tower is exclusively made and assembled in China. The Lite family is assembled and made under FW factory here in SA. All Lites and Lite 2 have Orion BMS Jr for LV and Orion & Orion 2 for the HV units.
The Orion has massive pedigree and is made in the USA. It's a delight to work with because it's in good English and for a skilled operator can allow some pretty radical stuff. There is a password protecting the nitty gritty for good reason. In the wrong hands can cause some harm.
Of particular interest the Orion HV is an adaptation from the EV market in the US and hence the price if you are looking to source one can be north of R100k. It's a BMS that can harness individually to all +200s cells and features Active balancing. So pretty special one big monster unit.
The Chinese EV market adaptation is slightly different topology. They have a Modular way of BMS control. A BAU in some cases , BCU and BMU. Modular making it significantly cheaper if anything fails. Each can be around R30k to R5k depending on the module.
Some useless info but must say very intriguing to be exposed to both topologies and to each their own. I see good benefits on both sides of the fence.

Then divide that number by 2 to extract the cycle count FW makes use of...

That BMS counts the cycle according to how they define it

It is there.
Look under the live text data tab.
Then select advanced parameters at the bottom.

Is it not the case that "cycle" is defined by, in this case, FreedomWon and not by the BMS? They will guarantee you so many cycles and then the guarantee will define what a "cycle" is.

@SRTosen ,
In @Steve87 's port 3 above, he specifies how to "talk" to a FW 10/8. You can't use PBMSTools, as only the FW eTower has a Pace BMS.
