What I meant is to establish an isolated mini grid with your inverter and a GTI. *Make absolutely sure your GTI is no longer connected to the street grid* No need to re configure your 2.6KW of panels and it gives you an alternative way of battery charging from the solar controller. All you need to control that GTI charging is a voltage sensing relay that switches two 30A relays to break the *AC* connection of that mini grid. You set the sensing voltage and a hysteresis for it so that the GTI helps with the early bulk charging and the solar controller keeps the battery up full for the rest of the day. I have used this arrangement for a few years now, it works wonderfully well.
