Validate my plan (or tear it apart)
display_Name posted a topic in Solar Power,
I'm ready to press go on my install (very excited). Would love some thoughts on the chosen setup, and if you have any recommendations for installers in Cape Town Northern suburbs, please DM me.
Here's what I'm looking to set up:
2 x Solis 6kW Inverters (S6-EH1P6K-L-PRO)
32 x Jinko Tiger 560W (JKM560M-72HL4)
Axe Struct Mounting system (Railed Roof Top)
SolarMD SS 4143 14,3kWh
Mock up of the roof attached. Mostly East / West, I've added summer / winter sunrise, midday, sunset lines to show morning and afternoon sun. I can't mount on the north facing roof (geometry won't allow).
My thinking is to have 4 strings of 8 panels per string, with the strings of each MPPT split East and West. So MPPT1 String 1 East and MPPT 1 String 2 West.
Was looking at 5kW Sunsynk inverters initially because the software is apparently pretty good, but the panels I'm looking at are 13.6A (over the Sunsynk rating of 13A), and the Solis 6kW at the same price looks like it makes sense with the additional headroom. Unless I'm missing something.
The equipment above comes to R185K excluding shipping. I'd still need fuses, wire, connectors, DB board, breakers, conduit etc etc... and of course the installation.
Does this look about right for a setup?

Whats the best small scale load shedding solution that can be wired to a DB
craig006 posted a topic in Product Opinions & Reviews,
I have a holiday cottage where I'd like to add some load shedding backup power. I want to wire it directly to some circuits on the DB, and only need it to power some lights, a router and a TV for about 4 hours (maybe boil a kettle if possible).
It would be a huge bonus if the system was quiet as the DB is in one of the small bedrooms. Having fans whirring away while guests are trying to sleep isn't going to be cool 🤣
What's the most affordable, long term solution here? Any specific products come to mind?-

Large 'Retro' Power System Display
HedgeSlammer posted a topic in Inventions,
Vital to being able to keep within the inverter output limits (and avoid importing expensive grid power unnecessarily) is having the means to display the relevant information in an immediate and accessible way.
That's what I told my wife, anyway. Really, I'd just scored a bunch of old RC servos on ebay for £5 and I wanted to play with them. 😉
In context:
It uses 6 servos, a Wemos d1 mini clone and a tri-colour LED. Dial faces are 3D printed, with a filament change from white to black (which turned out much better than I imagined, TBH).
The servos only had around 90° of sweep angle, so I 3D printed some little holder/gearbox things to get over 180° and provide a shaft for the needle to go on, plus some 'steampunk' needles.
All run buy the obligatory D1 mini and held together using the very latest in 'twist and tape' technology.
Yee-haw! 🤠
It gets fed the data from 'node-red' running on a Victron CerboGX via UDP packets over WiFi, updating as often as the data changes (approx 3 second intervals). The LED changes colour according to state, so 'All OK' is green, 'You're getting very close to/exceeding the inverter output limit, so if you don't want to pay for grid, don't turn anything else on' is red, then blue for 'dumping power into the hot water tank'.
It's by no means silent in operation. I originally made a single-servo version for just PV generation and coded it so that the meter movements were gradual (a kind of PID to get from one value to the next), but apparently it 'sounded like we have cockroaches' when it made it's ticky-scratchy transitions between values, so the big version just jumps between values with a 'zzziiiiiup!' sound.
It's actually quite reassuring to have an audible indication when the sun comes out for 5 seconds, or it starts charging at night.
I'd also put a little radar sensor in there, with the aim of having it detect when there was nobody around, so it could stop displaying to save power/noise. Unfortunately, that meant that every time you entered the room, all 6 needles would suddenly move at the same time, making you jump out of your skin and spill your horlicks, so we just leave it 'on' all the time now.
There's also a basic web UI, so you can see the same data on your phone or whatever, plus it's useful for troubleshooting:
I had fun and learned loads making it - and now it's become a family game to try to cook dinner without making the red light come on. 🙂
Libraries used are 'ESPUI' and 'servo', plus 'arduinoOTA'. Code, FreeCad file for the gearbox & stl file for the arrow-head needle are all in the attached zip.

Hi Please supply the settings for IMS303 battery please? -
US3000C supports 90% DOD while the US3000 only 80% DOD. -

Forgot to mention that Eskom was switched off on day of commission and still off -
By Rory Kilpatrick · Posted
Been up and running since 20/04. Am very happy . Done a bit of experimental stuff to see how it all works . Crappy inclement cloudy rainy weather since switch on but still not dropped below 39% at sunrise .Had battery powered roast chicken previous evening. Installer was not very excited about doing his first Solis install but he seems suitably impressed now. Pv peaks 10h30 till 14h00 at 75/80% with the odd 5200 watt spike which I assume is cloud related .Getting first pv about 15 minutes [100 watt]after weatherman says sunrise and ends 30 minutes before sunset. Generator not connected yet.All I can say is Thank goodness for this site . The options and independent opinions are invaluable . Two of my mates took only local mates advice and now that winter is upon us are not very happy. Question. How bad will east/west exactly , pv performance get %wise at latitude 33' with panels at 30' June 16th Question 2. What medication is available to stop me logging on to my app every ten minutes -
Hi @Timbo_vbwe used the Livoltek CANbus protocol. We have made use of Livoltek batteries.when there was a market short of batteries a few years ago. We were supposed the protocol some years ago under an NDA agreement. We then used a gateway that mimiced the CANbus that the Livoltek inverter would generate in order to allow an output to allow the battery voltage to be exposed. The Livoltek battery will not work without this CANbus message. It's their way of security measure. However, they have moved away from proprietary CANbus & now use Pylontech CANbus & so this allows use with Deye/ Sunsynk. You still however, have an issue because the Kodak uses RS485 Pylontech not CANbus. -
@1ougatthe 13amps is your maksimum operating current and the 17amps is your maksimum fault current. Your solar panels also have these values, make sure you don't go over the inverter values -
@LLTHB did you resolved your problem? Have the same thing
-
Thanks for the feedback. In 12v and 24v systems you run relatively high currents so it is of utmost importance to ensure no loose connections on battery connections. Hence the reason why manufacturer torque settings is so important. -
By mailerdaemon · Posted
Just some feedback ppl, in case anyone else has this issue. I found that the positive terminal in the inverter was partially melted, and was not making a good connection, or at least a partial connection to the battery. This seems to have been contributed to the issue. I have seated everything correctly, and everything seems to be working again. -
thank you everyone for all the info and advice, out of curiosity what is the actual differences between us3000b's and us3000c's? -
@007do you mind to post some graphs of the good performance off mppt 2? What is the best performance on a cool day on mppt no 2?
-
@Patrick OReilly I in stalled 2x 120mm fans at the bottom on a timer to control the temperature and it works well

@Steve87 what battery setting did you put in the Kodak inverter? I'm looking for the Livoltek BLF51-5 settings for a Kodak OG 5.48 inverter -
v4.34.0 What's Changed 🚀 Exciting New Features - feat: You can now visualise the efficiency of your MPPT strings by adding the `efficiency` attribute to your solar section together with the `pv[1-4]_max_power` (Maximum power of the MPPT based on the number and size of panels). The `efficiency` attribute can be one of four numeric values and activates the following display modes 0 - Disabled 1 - Graphic display 2 - Text display 3 - Graphic and text display This is disabled by default and you must set the desired display mode and specify the pv[x]_max_power in order to display this extra data. Some examples below 1 - Graphic display 2 - Text display 3 - Graphic and text display 🐛 Patches & Bug Fixes - fix: layout improvements. Remove space from battery soc. **Full Changelog**: https://github.com/slipx06/sunsynk-power-flow-card/compare/v4.33.0...v4.34.0 -
