It’s possible that the inverters aren’t setup to run in parallel mode. Can you share the settings on the multi inverter screen etc. Also is there a proper comms cable that connects both inverters.

Hi. Yes it is. I have a borehole and septic tank system. We don’t pay for municipal water or sewage.

Yes 7kwh

No problems in 3 years. I have them at my own home. See pic

Hi. 8000 cycles on the slimline vs 4000 cycles on the rack mount at 80% DOD

Thanks. Do you know where I can get gS rated fuses. Segen Solar supplies only gG fuses and that’s what they recommend when you purchase a Hubble/Sunsynk combo from them. Besides it’s not part of their warranty conditions. It’s all smoke and mirrors in my opinion.

I’m still waiting for a response on what’s a fast acting fuse between a battery and inverter.

I do have installs where the batteries are going on for 3 years with no issues but there is a batch that’s extremely problematic and blaming installers isn’t a way to deal with their own issues

I did that and guess what, they ignored that mail. And when they don’t want to put anything in writing, they call you and pretend to understand your point. If you look at how they respond, they are determined to void warranties. Hubble won’t last long if they continue down this path

It gets way better. This is the manager of the Johannesburg branch

Look at this response which shows how ignorant they are. Hi Leshen Just to clarify, you have installed 2 batteries that are exposed to a cable that potentially can be energised up to 160A. You do know that each battery is only rated to a maximum charge/discharge current of 100 Amps? I have attached the BMS log as requested. I stand by my initial email that the warranty is void, once again refer to our warranty document attached, specifically item #12. You are welcome to take any measures that you see fit.

Is Diagram 1 daisy chained?

I must admit, I’m not an expert on understanding those logs so maybe I need to get an independent review.

It’s connected as in Diagram 1

I suspect they swap cells from second hand batteries

I tried explaining that to them but they insist it’s the installation ie a slow acting fuse that’s the problem. This is what he said about daisy chaining.

Have a look. The BMS reported 145A and that’s with 2 x AM2. Then they spoke about daisy chaining which still doesn’t make sense to me. You will also notice that it’s the charging that is at 145A not discharging so what I think is happening is that when the cells become damaged for whatever reason they can’t regulate the current within the pack to charge them correctly. HL2106000122 #4266.xls

Initially battery 1 had a cell issue so I removed it and took it to Hubble and they replaced the cell. That took over a month. After installing the battery, the client said that that there seems to be an issue with the other battery. So I removed the second AM2 and took it to Hubble and then they claimed that the battery had 2 damaged cells due to multiple over currents. I showed them the log from SOLARMAN which they didn’t care about. I handed them the COC, which they asked for and still no interest. Now they want a PV Greencard certificate to which I said it’s not needed. After threatening to report them to the Consumer Protection Tribunal, they removed the labour part of the charge but said that they will deal directly with the client and will get a “reputable” installer to install the battery. Its R690 per cell ex vat plus an assessment fee of R690.

Hubble are now starting to void warranties whenever they deem necessary. I was told that my installation never had a “fast acting” fuse yet it’s the same fuse that is used in all installations that most Solar suppliers sell. I apparently used a slow acting fuse so the battery “over currented” and it’s an installation problem. This was after 24 months of no issues. I will never touch another Hubble product as their employees have no technical knowledge and their warranties are not worth the paper it’s written on. That’s why they can state “unlimited cycles” on the AM5. It’s purely a marketing ploy as they never intend to honour that warranty.

No because you will get a lot of nuisance tripping.

Hi @TaliaB it’s 100Ah 5.12kwh.
