Sunsynk 5.5 + hubble AM2

[Dani]

So I left lead acid 2 months ago and got a hubble installed. Yesterday I noticed that the Sunsynk is showing an error code F58 bms communication fault. I can't find any further details on the web. Do I take it up with hubble? Sunsynk? Or the supplier?

It depends on the cause, I got a once-off F58 error when I upgraded firmware. What doess your LiBMS screen say?

So it seemed to behave during the day so I left it but at night.... I will try swap the cat5e cable tomorrow? 

Here is the libms screen.

That's the fault code screen, not the LiBMS screen.

Oops here is the right screen I hope.

looked at the AM 2 specs, voltage should be 51 volts, 44 seems too low, call Hubble

There's definitely a problem. Tried swopping out the comms cables? It's where I would start, the most likely place, especially if it's intermittent.

I've swapped the cable yesterday and it seems to be behaving

Thx @Tariq dunno if other hubble users can comment. It's now at 46v and 60%?

Can be that the BMS did not fully switch on. I know on some BMS the voltage is quite low until the BMS gets the signal to fully switch on and then it rises.

 

[Dani]

Thx I'll keep an eye on it. Seems to be behaving now

Reviving this thread. Are you using a RIOT? I noticed that your LiBms reads 00, which is what mine reads when I have the RIOT connected. When I connect battery directly to the inverter, it shows LiBms:01, as well as SOH next to SOC.

Is this on a Sunsynk and AM-2 combo?

Which firmware are you running? 

Using CAN or RS485? 

Please post your battery settings screens as well as the Li-BMS screen. 

Thanks

Will do when i'm back home.
