Thanks a lot for your information. Now I'm using 2 weco 5,3k lifepo4 batteries, I'm a bit lost with diferents models and versions of firmware, I want to be sure abaut the firmware I need to use, I don't want brick the inversors, wich firmware must I use?
Thanks a lot for your colaboration.
Hi 2 years ago, I've buyed 2 axpert pf1, now I suspect there are two Chinese clones, I use the 2 inverters in paralel, but sometimes I have the problem that they switch to float to early, and the batteries are not full charged.
Attached the sticker of the one inverter, do you recognise as an Axpert PF1? Can I upgrade it?
Thanks a lot.
