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

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.

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'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.

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.
 
What’s you take on the whole geysey solar conversion kits

I’ve noticed a local installer and supplier offering 3x 550w, element, timer etc. to convert your geyser to a semi off grid solution

Taking what it can from the sun, and the rest from the grid

It doesn’t sound like a bad idea? Maybe some of you had this done before and I’m wondering if it’s worth my bonus to spend on

Or is it just better to go the gas route

It's pointless is you have (or are planning) whole home solar.

Could be a few reasons but likely it was balancing the cells.
 
Chatted to a friend( electrician) over the weekend

Started to mention that he seeing the 550w series panels drop as low as R1789 at herholdts, that’s of course his buying price

Is excluding the resell price.

People installing these, especially in George, are insane with their prices. The standard asking price is R22K (4 panels) and then goes up per panel you want mounted

I just can’t wrap my head around this price. I understand they install additional breakers and cables etc. But is that just the price because solar is the new money maker for these lads?

My guess is that George is an outlying area for solar parts so there's the outlying area tax.

So lets say assume they do everything correctly and that :
R8k for panels
R2.5k for combiner box
R1000 for 50m 6mm pv cables
R1000 for 8m of rails
R600 for mounting brackets
R300 - R1000 depending on quality of panel mounts
R3000 for metal conduit
R3000 labour per day
Odds, ends and shipping not taken into account here if they order from elsewhere

We are pretty much at the R22k mark
Honestly I think they arent making that much money. Pretty much labour.

I bought 3x extra Longi panels from a connection. Original installer charged me R10k for a new string, breaker, inline fuse upgrade to both strings, surge for new string and all mounting hardware to mount those 3 panels. It's not a rip off, but also not a bargain.

Hi all. I need some advice please. I have the above Sunsynk 5KVa inverter, with a 5Kw Sunsynk battery which was installed earlier this year. Due to issues with the BC in my complex, I wasn't able to get approval for panels until now.

I have one installer telling me that the inverter would do better with 425W/460W panels (10) due to it being 13A, and another telling me that the 550W are fine and are quoting me on 8 Longi 550W.

550W quote above

Can anyone give me a quick walk-through on this?
