So my new pylontech up2500 arrived today..
Fitted them and now I'm getting GX error #48 with incompatible firmware error
My system comprises of:-
2 x multiplus 5kw 24v (19 chipset with v2.09 firmware)
5 x Ve Can mppts (150/70) firmware v2.89
Cerbo GX (Latest firmware)
Old mppts are on 250kbs ve can and pylontech batteries are on BMS can @500kbs
I have read on here that the older mppts are not supported, yet someone said that thiers were working fine on a cerbo, but would not work on my original CCGX as it only has 1 can bus.
Vrm says that DVCC is forced on (by pylontechs I assume) but I don't want to be seeing a big error message across my display all the time, I may get used to seeing it and miss an important one..
So I guess my question is... is it the mppts causing the issue, or is there a later firmware version I can run on the multis?
I did see a later version possibly.. but I only have a mk2 interface, and the firmware said it needs a mk3...
Already spent a lot of money on my system, now with new batteries and a cerbo.. really need to get to the bottom of this..
Anyone help ?
