Hi Beat Thank you for the feedback and your suggestion with the 5K-Inverters. I will look if there are available here in Turkey. But concerning the cloudy sky problem, I will point you to the message of Nullmoden a few hours ago. Its only one example of many others I found on the web. No one is saying, that the Axpert has always a problem with that situation. But this problem seems to be happen from time to time. He also claims, that a simple PWM charger was able to do the job.

Hi everybody I'm living in Turkey and intend to move to the country. My house is still a construction site but I hope to be able to move in there in a few months. Because there is no electricity, I'm forced to get it from solar energy. Initially I was aiming for Victron. But for more a year now we've had such inflation and currency devaluation that I can't even dream of it. So I decided on Axpert 7.2kW and came across this forum while researching. I have read almost all the posts about this device and always had to think longingly of Victron. But it's okay: you get what you pay for. Axpert seems to have sometimes trouble charging the batteries when the sky is cloudy. This is a no-go for me because batteries that are always charged are essential for my survival. Of course I have a generator; but this should only be used in emergencies. So my first question is: Is it possible to attach an external cheap PWM-Charger without switching the cables? Maybe only by changing some values in the setup? Second question is: Do I have the option to sniff around in the menu without connecting the panels and the batteries? My intention is to get to know the device a bit before moving to my new location. Third question is: Can you rely on the voltage-, charge- and decharge-values of this inverter? Or would it be more reliable to obtain this data from an external device? Thanks in advance for the answers and also a big thank-you to the operator of this forum: the knowledge I have acquired here has helped me a lot.
