Hi all,

I've recently had a Sunsynk 5KW and Hubble AM2 system installed in my garage. Will add solar at a later stage when budget allows but for now this is just providing backup power for essential circuits.

Couple of questions:

• The inverter was bough in the middle of last year so the software probably needs an update. Is upgrading firmware recommended? Currently on the following:
  • Protocol Version: V0.2.0.1
  • HMI: VE.4.1.7
  • MAIN_1: V2.1.5.9
• It's been warm in CPT the past few days and the garage isn't exactly cool (probably need an extraction fan) but the inverter is pretty warm (around 30 degrees) and the fan is running almost constantly. I put a bike computer on top of the inverter and it got up to 36 degrees. Is this all normal when base essential load is 0.5kw with brief spikes up to 2.5kw?
• Is there a way to find historical battery temperature data via Solarman? The battery temperature seems high: currently at 28.8 degrees while idle. Hoping there's a way to see this temperature without having to check it manually all the time.
• Should my system be reporting any values under the "battery pack" sections of Solarman? Some sections are zeros but others have what looks like crazy values e.g. 1233AH and 1233% SOC and 49920 cycle times. Is this a battery problem or is it just garbage data that could be fixed with the latest firmware?

Hi ... I don't think the hubble has a place for the battery probe to go in, so the 28.8 degrees battery temp is probably ambient room temp.

Not sure whey you have multiple battery packs ... the only one that make sense is the battery.  I have single hubble on my sunsynk and it only show battery with the stats (your third last image).

May have something to do with the dip switches on the hubble?  It should be on master?

You should cycle the battery a bit and not leave it on 80% all the time.  The other guys can advise how to do this.

The Hubble seems to have a temp probe on all cells.
I use SolarAssistant and there the readings are presented for the highest, lowest and the average. My battery temps are always in the 29-30C range, it is not ambient temp that I can confirm. How accurate they are, well without actually opening the pack and using a calibrated IR thermometer, one can only accept what is presented.
I added a 120mm PC case can on the left side lower vent holes. Affixed it with double sided tape and that runs off a 12V battery. It extracts air and thus creates a dynamic airflow through the lower part of the pack. This dropped the High reading on mine by about a degree.
Having measured the outside battery case temp with a handheld IR Thermometer I get around 28C.

The attached graph represents the average cell temps for a typical 24 hour period.

I suspect thats garbage data. Some communication error between the Hubble BMS and your Inverter. Have you tried another Cable?
Also, did you set your inverter according to the Hubble recommendations?  https://www.hubblelithium.co.za/sunsynk-hubble-setup.html
