Hi, Does anybody knows fan size (e.g., 92mm x 25mm/38mm) or (e.g., 80mm x 25mm/38mm) for the Axpert MAX II 11 KW? Or if anyone has this inverter, and is able to provide a picture for the fan, it will be helpful to identify the model/size. Thank you

No, my architecture was different. I only had a similar problem with 30A charging and the Lib protocol. That's why I shared my experience. Unfortunately, I don't have any contact with Voltronic, but you might contact Taico so they can confirm which protocol you should use and the pins on the COM port. All the best.

I mean, from the inverter choose the battery to the (LIb) option, and then use the (mobile app) to increase the charging current. This what I did with the VMIII.

I mean, in my case, I have a battery which uses the LIb protocol, and data connection was established well with the inverter. However, when I tried to increase the charging current from the panel, nothing did happen and current kept to 30A. Then when I used the WatchPower app (over Bluetooth), I was able to increase/decrease the charging current easily - I did not understand why, probably a problem with the (moving) panel firmware. ibrahim007 problem looks that when he uses the LIb option, he no longer able to change the charging current at all - either a single or multiple batteries are connected (as I have understood), so probably it is a problem with the panel firmware when Lib protocol is used. @ibrahim007 Please correct me if I am wrong.

Have you tried to increase charging current through WatchPower app? Previously, with Axpert VMIII 5K, the inverter itself with a (Lib) battery refused to change the current, but when I tried using the app, I was able to increase the current. Give it a try, and make sure that actual solar power is enough for higher charging currents. All the best.

Hi all, I am not sure if the problem still exists, but AFAIK sometimes when multiple Axpert King inverters are connected in parallel, ONLY ONE (probably the master) is charging battery(ies) while the others are providing solar power to loads but not for charging. @Coulomb might confirm whether the issue still exists with the newer King II/or newer firmware (50.02)?
