Axpert type inverter with Hubble AM2

Featured Replies

Anyone using Axpert type inverter with Hubble lithium?

Can this be used successfully without comms between inverter and the battery as I see you need to install a cloudlink device to do this?

Opinions and past experience will be appreciated.

I do have a friend in capetown that has paired axpert mks2 5kw with am2, no bms comms. I dont know what his battery settings are, if you are interested, i can always contact  him.

Thanks that would be awesome.

Yes the work well, I had the setup with Hubble and Meccer 5Kva( Axpertking inverter) you can set the battery voltage setting which you can get from the Hubble website, I have since installed the Cloudlink as I want to monitor my solar setup

Thanks, so with the proper settings the Hubble charge perfectly?

The settings are on the Hubble Website. https://www.hubblelithium.co.za/axpert
And no, you don't need cloudlink. You can consider using SolarAssistant as well which will be able to more closely monitor not only the Battery but also the Inverter.
Costs would be pretty similar as you would need a Raspberry Pi and the needed cables. https://solar-assistant.io/#inverters

Cool, thanks

Have just installed 2 x Hubble AM-2 with the 5kVA MKS Axpert.  The Website voltage setting for "switch back to grid" is 47V.  Measured on a Victron BMV-700 this equates to only 60% discharge (40% left).  Has anyone else experienced this?  For the rest it runs like a dream.

Hi there have you tried going lower than the 47 float cutoff ? I have 2x Hubble and solar on my Axpert and bypass disabled but still goes back to utility in early hours of the morning, which I want to avoid in order for the solar to do the job. However not sure if I can adjust lower “safely”?

Having recently moved into a place with an Axpert MKS 5KW inverter and a Hubble AM-2 5.5KW battery, I noticed this thread while going through the settings. 

On the battery sticker the float and equilised voltages are shown as 52.6Vdc and 53.6Vdc respectively, but the inverter has been set to 54V and 56.4. Should I change this to match the battery sticker? The other issue I had was that the PV charging was set to max 60A, but when I enabled SBU (it's been running in utility mode all along) the inverted started dropping the PV input by mid-day. I then changed this down to 20A to get a stable PV charge. The inverter is supposed to be able to handle 80A solar charge, but I'm not sure if this is due to battery limitations or incorrect settings. Any input appreciated, thanks.

Set your bulk and float both to 53,6V. If that Inverter has been set to those voltages and the BMS actually didn't stop the charge at 53,6V, then the cells may have been affected already.
You can set your PV charging to 50A without concern. This is a 1C battery so in a Li BMS mode environment it will auto set to 100A charge in any case if the Inverter was capable.
In your case just manually set it to 50A.

60A is only 3000 watts when charging a 48v battery.  The inverter is probably cutting the solar at midday because the battery is full and there is nowhere for the electricity to go.

I can't comment on the battery voltages.

Currently Hubble recommends 53.8 as the Cutoffs on the AM2 in voltage mode

This wording doesn't make sense. If the batteries are full they won't take charge anymore,if you lower the max solar charge rate they'll charge slower for longer - that's it. If there is no load to load and no battery to charge PV will drop to match the usage

Indeed they have been playing around and upping the voltage due to the issues in the beginning.
This 53,8V recommendation started after they introduced the AM-2 version 2 and even that one still states 53,6V on the battery label. 
From own experience, pushing it to 53,8V makes hardly any difference and the original AM2 BMS very quickly settles at 53,6V.
The new Version 2 seems to have a more advanced BMS which does a much better top balance than the older BMS. 
In fact today is a perfect example.
Mine is set to 53,8V and you can see how the original AM2 already stopped charge and has settled at 53,6V. The new Ver 2 is still charging and will top balance for the next two hours or more to get to 53,8V 
The Hubble parallel trouble with the older and newer battery balancing they will never solve as I can clearly see the different behaviour of the BMS versions. But thats a different topic.

Yes, 53.8v is correct

If you ignore the manufacturers recommended voltages, then yes.
Hubble in their wisdom has messed about with the Firmwares and locally they now recommend 53,8V which supposedly masks the battery charge issues they had after their Firmware changes to display the same capacity for the older and newer version AM2. Original one being 100Ah on the battery label but having 110Ah with the original Firmware.
The Version 2 on the battery label is a 120Ah.
Then they pushed the latest Firmwares where both are now displaying 100Ah but this has caused huge SOC display discrepancies. I have had my fair share of comms with them. Batteries work fine but it's a mess in terms of SOC vs Voltage vs capacity when paralleling old and new. And they just ignore me now that I have presented them with the data

I also have the anomalies with my 4 batteries voltages settling,but it's fine,i'm getting 100AH per battery at least so that's within my tolerance

You are actually getting whatever the real capacity of the cells are. Only what's displayed is corrupted due to showing 100Ah for cells which are 120Ah in the Ver 2 battery. LiNMC at 4,2V is at full capacity. so you have a cell at 4,15-4,2V that is around the 120Ah charge. Their Firmware displays 100Ah and the whole SOC goes out of whack because of this. Once I sent them the results of that, that's when they decided not to want to talk to me anymore 🙄
They were very helpful up to that point, even logged into both batteries remotely via my laptop and installed PBMS tools to check out everything.
As said. the batteries and cells are fine. Their Firmware not so much. My own fault, should have never allowed them to convince me to load the new Firmware.

Nah literally i'm going on the KwH charge/discharges giving at least the 5KwH per battery I expect,anything else spare in the tank is just dandy 😆

If you want to downgrade I have the firmware from September 2021. It's still a version which shows 110Ah and not 100Ah. My battery is still fine with that firmware. Not sure, if downgrade is possible though.

That would be very kind, just not sure if that was already their first Firmware revision after the initial problems started.
My battery is batch 06/21 and it has given me excellent service,
Then I added the Ver 2 recently and I probably should have stuck with that ones original Firmware too. But they were quite adamant that I have to flash Firmwares for compatibility issues. Should have rather tested the two batteries in parallel with the originals.
Now I can't get the original Firmwares out of them. 
If that file is not too big, maybe you can PM it. Worth a try. Wish I could also get the original one for the new battery.
