@JaseZA has hit the nail on the head. Shielded & twisted pairs is fundamental with CANbus. No other way.

From memory the pylontechs in low voltage protection needs a 2A charge current to stay on. Helps if you have a 48V adjustable power supply to do this. Otherwise it's a catch 22. BMS awakens, states low voltage alarm turns off. Then turns on then repeats.

@TaliaBthe Sunsynk as well as even the Humble Kodak Voltronics machines can create 3 phase power with 3 single phase inverters. They have firmware that sorts out the 120° split of the phases. However, they need a means to Synchronize to & they receive this from the Grid AC input then follow along happily. I think the Dip switches should sort the Parallel issues out here & true 3 phase power will be generated... But the yellow Sunsynk cables they provide are very poor quality & are not shielded but are twisted pairs. But there is so many noise sources that can spoil the day that I always try to replace those cables. They are just not up fro the challenge. The Inverters communicate via Canbus Comms & that needs Twisted & shielded cable as a prerequisite.

Switch the dip switches off on all 3...you have no slaves in each phase. They are all masters on the respective phase. The Dip switch is a means for a master to know where the last slave lies. In this case there are no slaves. Also makes 100% sure to use Quality Shielded Cat 5e utp cable. The other non shielded cables can allow noise through.

The perfect knee jerk reaction to what was a horror show. So now everyone must be treated with safety mits.

What equipment? Residential or C&I? Many residential installers going out of business as the massive slow down has taken effect. Lots of suppliers also struggling on reserves. For the Companies that didn't have a Rainy day account that was full are all but gone.

@Virwat take some petrol & a match with you Just joking...We can laugh & identify this is a scammer but the scammers work with the laws of averages. It's an imperfect hit rate but it works. For every say 400 persons reached one poor sod will not suspect them & actually send money. That's what they work towards that one poor victim. So if that takes 2 weeks or 4 weeks the more people reached the more chance of fraudulent success. I have seen even cautious people caught up & it's actually quite embarrassing for the poor victim & often they don't want to report it nor visit the Cop shop to lay charges & add to that threats that come through.

Well done @TaliaB it's hard work & it's harder to fix someone else's mess rather than carry out a new clean installation from the beginning. Your client must be very happy & what's more is that most installation teams are not willing to take on such a challenge. So honestly well done

One of the reasons I have dumped the brand. They mandate that the Installer has first access & then retains access & allows a viewership to the client. I'm sorry to say that from the beginning I did not follow that mandate & was initially listed as a master installer with the brand. They then changed over to carry out an audit & wanted the installers to prove they have installed a certain number of installations. I always installed & asked the owner to create an account then share with me. So I actually couldn't prove the plants were installed by me, all I could show was that they were shared to me. In the end I told them to go fly a kite. My understanding was that the client has paid good money for this equipment & they are the official owners, I'm not trying to create a hostage situation, which is what I have often come across from end users in the past. I was just a facilitator of the equipment & it's correct operation & installation. The rights to allow changes & ownership of the plant should never be negotiable. I'm not against the brand or the equipment, I just didn't agree with their policy of the app & it's ownership etc.

Hi guys. I managed to sort @Buff out with his problem. His geyser was on the essential load. I have moved it to Non essential load & all is well now. Why would an installer place a 16A geyser on the essential load of a 25A capable inverter is beyond my comprehension. Battery is the Sunsynk 5.32kWh unit & it can manage 100A & is specified that way. BMS reports 109A max Discharge limit. We setup 100A. Absolutely nothing wrong to do this.

Would help if you share the inverter details...

Contact your installer for an RMA...

Hi @HansM I am an installation specialist with the ATESS & have installed & comissioned close to 60 units & touch wood I haven't had any problems or come backs. The largest plant to date is a 600kW HPS150 x 4 in parallel plant. It's a great machine if installed & setup correctly. It suffers unfortunately, from a very poor user interface & monitoring platform. Otherwise it's a very robust platform & delivers when called up. I have addressed both these problems with a good understanding of the machine & my company has developed a great EMS tool that will optimize & unlock a lot of value out of the HPS. Please feel free to contact me via PM...

I think one can understand that Solar Assistant can only perform as a one size fits all because it's a generic type of product. On the one hand if it was tailored for each case use just imagine the work required & how would you package such a product. I totally agree that HA is much more customized & one can concentrate the info of interest. However, I do agree it's not asking much to allow phase individual power charts to be exposed. That's not so far beyond the imagination of the humble user. Cell voltage delta on the other hand that may be a more advanced type of information package. I guess it's hard to strike a balance between an advance user & a new user. But I have to Vito HA it's on another level, however, you have to know what you up to to be able to extract what you want.

If you find this available on the Sunsynk logger platform then it's available also to solar assistant. The Modbus RTU protocol must expose it for solar assistant to be able to chart it. The solar assistant is only as good as the Modbus exposure. So this may very well be a request that needs to be escalated with Deye/ Sunsynk. I have not referenced the Modbus to make sure.
