Hi,

I am posting this topic on behalf of a good friend who is questioning the discharge of his Hubble AM-5 batteries - he has a Deye 12kw 3-phase Inverter with 3 x Hubble AM-5 batteries with a total of ~15kwh (installed approx. 3-years ago). The Hubble AM-5 batteries are 1c batteries, so in theory he should be able to discharge at approx. 7kwh)

Hopefully someone can provide some insights into why the below is happening/what is configured incorrectly.

In summary, looking at his battery use, the discharge never seems to exceed 5k from his batteries even if his load exceeds that - as an example, I have attached a picture/graph showing his load above 6k (6311w) and yet his batteries are only providing 4.9k and he is pulling the rest from Eskom (1.15k) even though there is battery capacity available - why would this be happening as he should be able to pull the full load/requirement from his battery (and pull zero from Eskom).

I have also attached his battery settings and BMS as well as a graph from Solar Essentials showing his battery has never exceeded 5k

Does anyone have any insights into why this behaviour could be happening?

Thanks

Are the comms cable between the batteries connected and are the dip switches set correctly will be my first check.

I don't have a Deye but a Sunsynk and on that last screen it looks to me it is only seeing 1 battery. I'm pretty sure those current limit should be showing 240A at least for 3 batteries. When I was on 3 batteries (different battery make) I had those showing as 240A on charge and discharge and when the comms cables was pulled during some testing those would drop down accordingly.

Perhaps worth a double check to make sure.

LiBMS screen showing 100A discharge limit. Something likely wrong with the inter battery communication, or dips switches set incorrectly or something not correct with the battery inverter communication.

PROBLEM SOLVED!

I am actually a little embarrased as I should have checked his settings before posting - nevertheless the point here is never assume that your installer setup your installation correctly :-(

In essence, everyone was correct - the dip switch settings on 2 batteries were wrong as well as the communication cables were not in the correct ports - thanks @-cK- and @I84RiS - your posts made me double check my friends settings and we found it.

Herewith the correct settings / cable ports (he has a 12kwh Deye Inverter with 3 x Hubble AM-5 batteries).

The Picture of the Li-BMS now shows the 300A that was missing previously :-)
