All things Sunsynk (Deye, Inge, etc...)

I'm thinking of getting another battery for my sunsynk invert, current hubble 5.5kw has been doing well, the majority of the time reaching 60% on 'heavy' use days (normal days see it drop to 78% per loadshedding). But I was wondering, is it a kak Idea to buy another battery (same model) and connect it up to double the available battery storage, or is there a limitation I will experience or see with the new battery

How do you have your work modes set up? Are you still using grid?

If you're only reaching 60% then getting another battery would be a waste of time unless you're currently only using it for backup during outages and want to move to a more "off-grid" setting.
 
The Ponytail is failing me again...

After the monumental, long awaited and much delayed move to Region 2... I now have some historic data back.

BUT, at first glance I see 2 and 3 Dec all data missing... ?

Anyone else?

Finally decided to spend the money on the cable and get my batteries connected up to SolarAssistant. Happy to see everything looks to be exactly what I'd expect (the third battery was added months later than the first two).

Super happy that the battery cycles are identical on the first two, the BMS doing its job. It also seems to be, at first glance, prioritising the new battery slightly as it has less cycles - curious to see if this is the case.

What batteries are those as I know with pylontech I had to connect the newest one as battery 1.
 
I'm curious what other people's battery cycle/day ratios are like.

My cycles sitting at 144 on the oldest batteries and had them installed for 278 days, so that's around 0.5 cycles per day which I don't think is that bad. I'm discharging to around 30% every day now but this is only for around the past 3 or so months so I expect I'll see slightly higher cycles per day going forward.

Same here. I hope that it will still appear at some stage:

Curious, how did you connect the batteries to the Pi?
 
I have a 12 kW Deye with a SolarMD battery - salesman advice to also buy logger V2 - but you can only use Logger or Dongle, not both, and Logger does not give you remote access to the Deye. And with the dongle, you are again limited with access to the SMD. So actually they are not compatible, the Deye with a SolarMD.
How did you connect the SolarMD to the Deye? CAT5 cable?

I am doing about 300 odd cycles a year, have been since the start. I often discharge to 5% SOC in winter, in summer generally to 40% SOC.

Have had the pack shutdown on 3 occasions previously due to low voltage (one was a test and the two other occasions I forgot to chage settings)

I like to keep my MAINS breaker down when I am comfortable that the weather will not cause me to need some grid (the grid trickle usage irritates me and I prefer seeing my prepaid stay on the same number of credits for days/weeks).

It got me wondering, how much up and down can a MAINS breaker handle in its life? I am probably doing 1 down/up every week or so, sometimes longer between needing some grid juice.

Will the breaker handle this wear or am I asking for a premature failure in the future? I know you can get WIFI 63A main breakers but I am not going to go down that road.... yet!

A good quality switch can take some manhandling. I'd say it's good for the life of the breaker.

You could look at Solar Assistant (https://solar-assistant.io/) potentially for local logging and remote access, and use it in conjunction with the SolarMD logger. Depends what ports are used by each device, for Solar Assistant you can check their site.

My Sunsynk batteries are at 0.44 cycles per day for the battery installed on the 31st of Jan and 0.43 cycles per day for the battery installed on the 13th of Feb. Work mode timers set to a minimum of 40%. Shutdown set to 20%, but I have never reached that.
 
Got me thinking how many cycles my Hubble battery has completed

But if im not mistaken that’s a bit tricky without solar assistant.

Wonder if hubble can log into the cloud link unit and advise me. Let me go bug them a bit
 
Small observation now that I have monitoring data for the individual batteries. Last night I noticed that the newer battery sat unused and fully charged for quite a bit while the older two were getting used equally. Just before 8pm though it kicked in and all the batteries start to kind of equalise.

I'm not too concerned most of the time they're used quite evenly, just a bit curious why that battery didn't get used for that period. I will check again tonight if I see the same behaviour.

I've seen this with my two FW batteries on the same CAN bus. Sometimes one gets used more than the other. Not sure what the decision is - possibly it uses the newer one more to even the cycles a bit.

Mine does exactly the same, has been doing so for the last 2.6 years (the never one starts discharging after the two older batteries that are 3 years old).

The likely cause will be differences in the internal resistance of each individual battery or there are slight voltage differences between the individual batteries.
