@Sidewinder, thanks for confirming. I did notice earlier that when I added cards for the current/power/voltage that I can click on them to see the graphs as above. But with my Energy Dashboard it unfortunately does not aggregate together for the day/week/month, would have been great to actually see my Geyser consumption as a part of the total for the day. I will be adding a couple of Bneta smart plugs to start tracking the consumption of the large appliances like the dish washer and maybe the aircons to understand how much they really use.

After keeping an eye on the Energy usage for the newer CBI switch I saw that it simply stays on 100W, not increasing at all.

I finally got my CBI Astute Smart Controllers connected to Home Assistant via HACS and Tuya Local. But at this point I noticed a couple of things. My one CBI Astute is newer and reporting as V2 which also shows Energy, but the older one does not (even though both seems identical on the CBI App and were recording power/energy). Any Idea how I can or if it's possible to report energy on the older model? Will be great if I can add this as part of my Energy Dashboard which has all my inverter (Sunsynk via Solar Assistant) values on there including total consumption and consumption from the grid. When adding the devices with Tuya Local I could not use "Manually provide device connection information" even though I had all the information like the IP, Device ID and Local Key. It just worked using "Smart Life cloud-assisted device setup". Now for the next step to set up some automations like getting the geyser to run like a solar geyser and heat up once a day when the sun is out.

Decided to add another string of 5x 550W panels to my Sunsynk inverter 2nd MPPT

Item Wanted: 2x Canadian Solar 450/455W Panels, Model Number CS3W-450MS or CS3W-455MS Packaging Essential: No Desired Age: Maybe 2 or 3 years Location: Gauteng (I'm in Roodepoort) Willing to accept a shipped item: No Ballpark/Budget Amount: Less than R2k per panel (used and that is the price of the new CS6L panels of same Wattage)

Item: Growatt 3KW/48v Inverter (SPF 3000TL HVM-48V) Age: 2.5 years (bought April 2021) Price: R5000 Payment Method Accepted: Cash/instant-EFT Warranty: No (only 2 years on inverter which have lapsed) Packaging: Box/Manual for Inverter Condition: Still Working perfectly, cleaned out all the dust when the new inverter was removed Location: Roodepoort/Randburg Reason: Upgraded to 5KW Hybrid inverter Shipping: No Collection: Yes Link: https://www.solarwaysuppliers.co.za/product/growatt-3kw-solar-inverter-48v/

I have been using a Growatt 3kw 48V Offgrid inverter with DIY 2.5KWh battery (16S1P using 70200 cells and 30/60Amp Daly/LBSA BMS) since April 2021 to help me cope with Load Shedding. I added 2x 455W Canadian Solar Panels in June 2021 (just a simple 2S1P configuration). I Added Another 2x 450W Canadian Solar Panels in June 2022 to create a 2S2P Configuration. All this have been working great, and on Average I have been able to generate about 15%/100KWh of my average 650KWh monthly units not to mention the fact that the Load Shedding inconvenience was only a problem for the high wattage appliances aroudn which we needed to plan (like oven and dishwasher). With the Increasing eskom costs and a good bonus I a few month back I decided to upgrade to a Sunsynk 5KW Hybrid and Dyness BX51100 Battery. After installing the battery and inverter I was pleasantly surprised that the 4 Panels which I reconfigured to a 4S1P was now producing about 10kW on a sunny day. But I also bought a couple more 455W panels, but this is where the problem starts. I noticed the physical size of the panels is different and when looking up the spec sheet I found that the Canadian Solar CS6L-455MS and the older panels (which I think is CS3W-450MS and CS3W-455MS) is no where close to the same in terms of Working Voltage and Amps and I dare note connect them into a 6S1P configuration (dont want to burn anything) Does anyone know where I can find some CS3W-450MS panels and if anyone is still stocking them? I have also emailed the supplier where I bought these but to my research it seems Canadian Solar is not manufacturing the Older HiKu (CS3) modules any more. As an Alternative I guess I can just sell the 4x CS3W Panels and add get 4x CS6L Panels (slight lower voltage with slight higher Amps, but it appears the Sunsynk inverter will be working OK with them)

Just swapped out my DIY 2.5KWh battery with regular (non-smart) BMS with a Dyness BX51100. According to Dyness Documentation and the correct/Growatt comms cable (seems like a straight though wiring) I cannot get the inverter and Battery to speak to eachother. Dyness Manual suggests that Dip Switch 2 and 3 needs to be set to on for the RS485 to work, but no suggestion on where to plug the cable in on Growatt inverter and what the settings on the growatt inverter needs to be. Anyone else got comms working on a Growatt SPF 3000TL HVM? Currently have the battery set as US2 (like with my DIY battery) and Charge Voltage at 56V (Dybess Manual suggests 56-57.6V) and this is working as expected.

I'm also looking at upgrading my 3KW Off-grid Growatt to a Solis S6 5KW Hybrid, and finding a supported battery is a bit of a headache. I see Hubble now states on their website that they are Solis Supported (think a Hubble AM5 will be great because of 1C rating and unlimited cycle warranty, but a bit pricey). https://www.hubblelithium.co.za/ Other "budget" battery I can find is the Dyness A48100, but this one with a 0.5C (0.75C peak) rating which is not ideal (but the price is good). Interesting that the BX51100 is not on the list (wonder if BX58100 is not maybe a mistake since I cannot find it with Google). The Pylontech UP5000 and ShotoSCD10-box batteries have similar specs. Will be really nice to see localy assembled/branded batteries like the LBSA, Mageneto and Cyclone supported by Solis.

I will be keeping an eye on the supported battery (or rather BMS Protocol) list...

Since the Solis worked with the Hubble AM2 (which is not on the compatible battery list), I assume there is a lot more batteries that will work, like the Cyclone C5 (Solarway Suppliers) or even the Magneto batteries? Will be excellent to see Solis Inverters work with Solar Assistant (been using it for about 2 years now). Love the fact that they are quieter than the Deye/Sunsynk. My Growatt is a bit on the noisy side when the second fan starts up (measured 30dba next to it with the one fan running, but kicking up to 60-65dba when the other fan starts up)

That's correct. All the electrical work for the current inverter is already done (for 40A), so it should be a straight forward swap.

I'm looking at replacing/upgrading my 3KW Growatt Off-Grid inverter with a hybrid to start "harvesting" more solar power and save on my Eskom bill. Was looking at Sunsynk or Deye, but the 6KW Solis is really intriguing, especially after the review, great work AlexTZA! I'm currently using Solar Assistant on my Growatt and very keen to see the integration with Solis when they release a version later this year. Don't really care too much about not having a screen on the inverter and manage it via my phone. Who is a good supplier of the SOlis S6 Pro inverters in Gauteng, preferably Johannesburg area?

I recently bought a Kool Energy 1KW Lithium (1.3Kwh 24v integrated Lifepo4 Battery) to use as a UPS on TV/Decoder and a couple of lights. The inverter have been doing exactly this for the past 2 weeks, but yesterday and last night during load shedding it turned itself off. The Manual is kind of hard to follow (online version's pages are all messed up: https://www.solarwaysuppliers.co.za/wp-content/uploads/2022/11/KOOL-1KW-LITHIUM-MANUAL.pdf). I have not touched the settings and left it at default. Any ideas why the inverter is not staying up? Note that the load is under 400W when the lights and tv/decoder is on, at night when everything is switched of this is maybe 40-50W

I helped my Sister in Pta East with a similar installation (Sunsynk 5KW + Dyness A48100 + 6x450W Panels on first MPPT), generation during the day is about 2.5KW when the sun is out. Everything seems to be working very well, but I'm not sure if the BMS and Inverter is talking to each other like they should. Inverter shows Battery SOC, but the per-cell stats/volts is not reported by the inverter (Settings --> LI-BMS Option). @mzezman, Is your inverter reporting the per cell voltages? Can you possibly share you battery/inverter configuration? We have connected Sunsynk Inverter BMS CAN Port to the Dyness A48100 "In" RJ45 port. Battery is also configured as Master 1 (DIP set to 0-0-1-0 for positions 1-2-3-4). We also "restarted" by switching everything off, and then turning the battery on first and then the inverter.
