I'm sure @Sc00bs will come visit if you offer him enough beers 🤪

All from this Forum, running in Home Assistant - see here and vids from @Sc00bs and then:

Thanks @Sc00bs There's no leaks... certain members bath in the evening, every evening... It's a real battle I tell you 🤣

Basically the whole house (minus the oven, electric stove and outside fridges (soon to be added to non essential side) are on the inverter - really have to be careful when the inverter goes into islanding mode during load shedding as I've overloaded it a few times. I've spent a bit of well spent $$ of Tuya smart plugs to get insight into what devices are drawing and made an effort to turn these off during the evenings (Jojo tank pump etc). Also realised that the outside fridges mentioned above are using 3kWh per day with a smart plus educating the fam about turning lights off... it's a challenge but I'm enjoying it!

Thanks for the message and question. Certain family members insist of having a hot shower at 06:00 so the 1 geyser which a 4Kw element switches on from 04:00 - 06:00... Regarding the shading - there's none, though our poor palm tree had a proper haircut when the initial 10 panels went up but it's growing back quite quickly - will need to trim it again for winter.

Just an update on our production: System commissioned on 04/10/23 - the few bad days of weather in Gauteng were brutal and messed my graphs 🫠 (Past 31 days) Monthly production: All geysers have also been moved onto essential side Found that our outdoor fridge and freezers (on another phase) are making Eskom $$ so these are also going to be moved onto the non essential side - should save an additional 3kWh per day. Still super super chuffed with how things are working!

Thanks - found that setting panel_mode to false and setting card_height: 480px makes them all line up nicely. Once again, I really appreciate your work on this and willingness to help out with my ridiculous requests

Thanks so much - it looks awesome Is there any way that I can get all the cards to be similarly sized (all are currently set to default size)

Awesome, thanks

Hey, Thanks - I've removed the card height adjustment and left it as is (default). What I have found is that depending on the screen used, the vertical scaling seems to be changing inconsistently: 15" laptop below: I can send you screen grabs of this from a 24" & 27" monitor later if that helps.....

Thanks so much for this! Just struggling with the size of the icons on the far right: (seems like the scaling is off/layout setting is wrong or I'm doing something wrong) Card_height set to 480 to match your other horseshoe cards Autoscale is set to false Here's what my whole screen on PC looks like: View type: Horizontal (layout card) Also, what does the green circle under the inverter represent? Thanks once again!

Thanks so much... would be awesome!

Hi @slipx Would it be possible to add more than 2 essential loads? Currently on the essential side we have 4 big loads which I'd love to visualise: Pool pump Main Geyser Second Geyser Kitchen Geyser I'd really like to add this to flow card and I've tried changing the additional loads to 4 and adding in the required names, icons, entities (essential load 1, 2 etc) but no luck.

Unfortunately, we're big consumers... 4 Adults, 1 baby, 3 geysers, dishwasher, Jojo pump, pool pump, too much networking equipment plus lots of cups of coffee during the day Trying to reduce evening load - worked out last night that I'm going to bypass the Jojo pump from 18:00 - 08:00 which should help.

Thanks so much... super super chuffed with the performance!

Did 42.5kWh today - forecast was 47.7 - I think that if our load was higher today, we would've hit 47....

Here's my Solcast forecast for the next few days: From the legend @slipx

The past few days have been all over the place.. Typical day: Using up all the electricity day: Today: At least there was some sunshine today to charge up batteries and take the load of some of the geysers. Tomorrow and Wednesday are looking great!

So far they've been flawless.... have 2 more of these units in my wishlist

Didn't think to look in the owners manual. Here's the details if anyone else needs them:

Hi guys, Does anyone have any info regarding the status LED's on the Greenrich WM5000? I.E: What is the SOC when LED's are blue/yellow/green etc I've left a message with Elleyhill Power to try find out and can't find anything on the internet... Many thanks

Thanks for reminding me, Mike Cronje of The Cottage Project designed, fabricated and installed the structure. His details are: +27 61 002 7678 / [email protected]

Hi guys, After initially sourcing our own components and getting a "sparky" who claimed to have many years of experience and certifications ("PV4 AREP") in solar, we started down this rabbit hole with: 1 x 8kW Sunsynk Inverter 10 x 460W JA Mono Solar Panels (installed onto our north facing tiled roof) 2 x WM5000 (4.95kWh; 1.5C) Greenrich batteries All worked ok but soon we realised that we needed more PV and more batteries and after doing research about our existing install, I started to question the initial installer about his work. Some issues that I picked up were: According to him, you can put AC and DC cables in the same trunking, as long as the AC cable is surfix, it's shielded so it's ok 🤔 No indicator lights in the AC combiner box needed as there are indicator lights on the inverter At this point we'd already had a north facing galvanised frame designed & installed next to our existing array and purchased an additional 10 x 460W JA Mono Solar Panels and 1 x additional Greenrich WM5000. We did a self install of the panels which was fun (despite the Mrs complaining about all the time on the roof) and mounted the battery. Once the panels were installed, I decided that it was time get hold of the legendary @Steve87 who not only gave me guidance in terms of my self install (earthing, frame spacing etc) but also came past to inspect and quote to fix the existing install & commission the new bits of kit. Amongst some of the issues he found were: The items listed above 6mm wire used instead of 10 on the AC side (DB to inverter) Different battery cable lengths and super dodgy cable used Max charge rate of batteries set to 40A Steve feel free to add more issues found here 🤣: ______________________________________ ______________________________________ The system looks like this at the moment: 1 x 8kW Sunsynk Inverter 20 x 460W JA Mono Solar Panels (5s2p Mppt 1 and 5s2p Mppt 2 total 9200 watts 21.84A/Mppt) with 30A fuses 3 x WM5000 (4.95kWh; 1.5C) Greenrich batteries After a perfect day in JHB, it's evident that we have gone overboard on the PV, so wondering if I should start solar pooling with my neighbours or installing more geysers 😝 Next (and hopefully the last) phase is more battery storage... convincing the Mrs could take some time but I'm onto it! Safety of the whole system has always been my most important requirement and knowing that Steve has fixed, commissioned and optimised the system has put my mind at ease - I cannot thank you enough! And finally time for some pics:

May be a silly suggestion but I recall when I tried to get this to work, I mixed up the pairs on the ethernet cable (Type B Config) going to the RS485 to TTL converter - switched these over and the same modbus error disappeared and it started working. I removed the R7 resistor and doubled up the ethernet pairs as seen below. Here's a pic of a ESP32 Dev board that I made for a colleague - powered using a cellphone charger into the micro USB port If I recall correctly, the brown jumper is power 5V from the ESP32 and the white jumper is ground (ran out of red and black jumpers). Used a wago type connector to bridge the DE & RE pins on the RS485 converter.
