Running the following versions on my NUC Core - 2024.2.0 Supervisor - 2024.01.1 Operating System - 11.5 Frontend - 20240207.0 I have a node function that looks like this //var fulltopic msg.topic = "homeassistant/sensor/SunSynk" + "/" + "/" + msg.shorttopic + "/" + "config"; msg.topic = msg.topic.replace("//", "/"); msg.payload = { "unit_of_measurement": msg.unit, "state_topic": "homeassistant/sensor/SunSynk" + "/" + msg.shorttopic + "/" + "value", "name": "SunSynk_" + msg.shorttopic, "unique_id": msg.shorttopic, //"state_class": msg.state_class, //"last_reset_topic": "SunSynk/lastreset", //"last_reset_value_template": "1970-01-01T00:00:00+00:00", "device": { "identifiers": [ "SunSynk" ], "name": "SunSynk", "model": "SynSynk", "manufacturer": "SunSynk" } } if ((msg.deviceclass != "") && (msg.deviceclass != "none")) { msg.payload.device_class = msg.deviceclass } return msg; But I'm getting the following errors in the log.

I've learnt so much since that post of mine. Firstly, not to hijack. Secondly, 1C batteries for the win. I ended up installing an AM2, and almost 2 years later, I added another AM2. Happy with my setup, except that I should have gone with an 8kw. The upgrade now is so pricy, almost does not make sense.

hey @suds7162 what is the rating of your fuses?

If I may ask an off-topic question. What is the rating of the battery fuses that were installed with this system?

Ah, that clears it up for me.

Thanks @Leshen I am no electrician, and only dabble slightly, so forgive my ignorance. I am trying to understand why, what looks to be a +200amp battery fuse disconnector, would be installed, when the 5kw has a max charge/discharge of 100amp, and the Hubble AM2 as a max of 115amp charge/discharge rate (old one has 100amp max). The only reason I can think is that you upgrade to an inverter that can handle a higher DC charging rate. Is that the reason?

What thickness is the wire between the inverter and batteries?

Beautiful installation. I true pleasure to look at. If I may ask a question... Did you consider using a busbar for the installation? If you did, why did you decide against it?

Items: Hubble AM-2 5.5KWh Age: 20 months Price: R27,000 Payment Method Accepted: EFT Warranty: If transferrable by the supplier (power forum store), the balance of 5 years. Packaging: None Condition: Used but in excellent condition. Location: Cape Town Reason: Upgrading capacity Shipping: At buyer's expense and risk.

So yesterday I received a general email from my broker about insuring solar & backup systems. While I had immediately done this upon installation, I thought I'd reach out anyways. It seems that I have all the required documents, which everybody with a commissioned system should have, except a document indicating compliance with the latest edition of SANS (SA National Standards) 1014-1 (Wiring). This is not the same as the CoC (which is a SANS 10142-1) Does anybody know anything about this? Has your installer provided you with said certificate? (Actually, the other document that they wanted that I know I didn't get, unless it was in the inverter's box, was Compliance with NRS (National Regulatory Service) 097-2-1 (Utility interface/inverter), which I just downloaded off the internet for Sunsynk.) This is besides the point though 🙂

Don't waste your money on a Riot mate. They are overpriced fridge magnets at best

@Donovanvdb where do you access the Pack Information from? I would like to see what my Battery Cycle is at

Nice one, thanks!

This is pretty. Care to share the dashboard json?

Yeah, I was being overdramatic. Mine works, but is better served as a fridge magnet. One thing that was good, was the battery cycles... until they disabled it. I feel cheated out of the R2,500 that I paid for it.

Riot doesn't even work for Hubble...😠

Damn, I went on to the roof today when I saw my production dip for no apparent reason. Turns out, in winter, the old hag's palm tree next door covers 2 panels for about 1.5hrs, and there is nothing I can do about it. I even offered to have the old branches trimmed, and she refused.

Has anybody upgraded to Node-Red 12.x?

This did it, thanks.

If you are referring to the inverter modbus-client node's unit-ID attribute... It was already set to 1. Any other ideas? Edit... I just noticed this log message

Hey peeps, My 5.5kW inverter was was updated to firmware e424 - MCU:3374 this morning, and since then, my logging seems to have stopped. I was previously running e419 MCU3162. Any guidance to get this up and running again will be appreciated. I tried pulling a debug node onto the modbus queue info, but nothing came from it.

Thanks, reimported those flows, and it's working now

Hey @Sc00bs, how do you get access to this dashboard? I am getting tired of going to my inverter every time to change settings

Hey Niel, Yes, @Leshen's solution solved this problem.
