Multiple sources in an ac coupled system

Edsimon

I intend having two battery-based inverters in an ac coupled system. A GS7048 and Conext XW+. GTIs are SMA and Goodwe. Any issues envisaged?

So you want 4 different make inverters to all play nice? They sound like different age equipment also.

Might be easier if you describe what you are doing now.

Usually the last thing I want to do us AC couple offgrid. It can be done but when something goes wrong, it can be very bad!

I currently have 2 units of Goodwe GTIs AC-coupled to a GS7048. What I want to do is to sync the same network with the output of a Conext XW+. You're correct on the disaster that can result from things going wrong in an offgrid AC-coupled system. Presently my strategy is battery voltage-controlled relay switching a contactor to a dummy load(water heater).

You will have more issues with XW+ as it is not as well designed for AC coupling as XW pro.
There is a manual for AC coupling on the Schneider site.

It hurts my head to think of trying to sync/couple to (2) different make battery inverters. I live in the state of Nevada and we gamble on everything. I would not take your bet on this. Wish you luck though.
