Dual MPPT not showing PV2 at all

[GastonJ]

Good afternoon, I have a Axpert Plus Duo 3000-24 from Voltacon

Using Watchpower I can see and monitor my 2nd array (PV2) and can see it is fully working from both Watchpower and the LCD panel.

However using this I am unable to view/monitory PV2

In the above I disconnected PV1 - since it will pick up and monitor PV1 without issue and it certainly doesn't pick up PV2.

I've disconnected my PV1 array, below is a screenshot from Watchpower showing PV2

While I know most people will have a single MPPT controller - has anyone any ideas on how to resolve this? Any help appreciated please.

Did you have any joy with this? I will need it when I add something to my pv2, I'm not actually getting PV1 in watts at the moment but get voltage and amps, it might be as easy as changing the PV_in_watts to PV1_in_watts and PV2_in_watts

[GastonJ]

Hi Darzl,

No, got nowhere with it. I do get both feeds on Watchpower just not anywhere else, I've tried a few things so far all to no avail. That won't stop me looking and trying to work out how Watchpower sees it and yet this doesn't Perhaps it's just me. I will in all likelihood decompile the java into it's components and find out why, it's just a matter of time - which is never on my side.

I switched to https://github.com/catalinbordan/docker-voltronic-homeassistant and now I get my PV power as PV_Charging_Power1 in watts, probably only need to add another line PV_Charging_Power2 or something similar

[GastonJ]

Thanks I'll take a look.

This is a little bit old but I added support for a second mppt and created a PR to the repo above. https://github.com/catalinbordan/docker-voltronic-homeassistant/pull/2. The changes are in my fork in case anyone is interested https://github.com/saschalenz/docker-voltronic-homeassistant
