Do I get you correctly? We pay 1200+;- Euros for an SMA-Advertising-App???

One further problem evolved. I hope I only missed the way to solve it: How can I connect 2 or more charger units/inverters to one battery block?

The first point mentioned by Jon is an issue since back in 2013. And also the lack of the 3-D-Rotation is definitely not state of the art anymore. Especially for a program with a 4-digit-price. The software maybe was good in the 2000's, but today, 10 - 20 years later? Compare the value-for-money-ratio with AutoCAD or MatLab - PVSol's price is way too high for what is offered. The only good thing is the incredible database - but for somebody like me, travelling a lot and therefore often having problems connecting into the internet, the new policy with only online-database is now getting a pain in my furthest backward part. Overall I believe they are on a quite good way of loosing pace if they don't get into refurbishing their software and marketing policy. My only hope are people like you and me - explaining their needs and hopefully be understood as constructive critcizers.But to be honest... If the way they handled my requests on phone reflects their attitude, I have considerable doubts about helpful progressive changes.

Dear Developer Team After reviewing your software I encounter following problem: The PV-Generator is charging the batterie 48 V with a DC-Charge-Controller, that includes an MPPT-Tracker. On the same DC-Bus lies an Inverter for 230V(AC)-1-Phase, connected to the house system - in such a way, that there is no feeding into the external power-grid. This is a quite sensible and surely not seldomly used constellation for OFF-grid and ON-grid systems to reduce inverter losses by canging forth and back from DC to AC again to DC to be followed to AC. Studer/Steca or Victron for example are offering such hardware. How do I implement such a constellation with your software PVSol? Best Regards
