SolarEdge HD WAVE Inverter Panel Mapping

About 2 years ago, I had an inverter die and didn’t realize it for a few months. The company that installed and was supposed to monitor my system went out of business. I found a guy that was a certified Solaredge technician to replace my inverter under warranty.

At the same time, he discussed adding panels to my system. So I went from 6KWh to 7.6KWh. I was told that my inverter could handle the load, but that was incorrect. I had a 6KWh Solaredge HDWave and it was clipping way too often. The installer said he incorrectly thought I had a 7.6.

I asked about just upgrading to a bigger inverter, but he suggested installing two inverters and splitting the load. He was able to get me a second 6k inverter at no additional cost to me. I should also mention that I have two Tesla powerwalls. When he installed the second inverter, he split the load between the two inverters. However, instead of routing the output of the second inverter to the powerwalls, this new inverter goes directly to the grid.

The problem with this setup is that the Powerwalls do not see all of the power generation AND the batteries do not always fully charge because the power output of panels is halved to the powerwalls. This occasionally causes me to purchase power from the grid during peak times.

I can no longer get in contact with the technician.

I could be mistaken, but it didn’t seem like he had to physically balance connections of the panels to the inverters and that he was able to map/assign the panels to the second inverter via software.

What I’d like to do is change this mapping so that as close to 6KWh goes to the first inverter, and therefore the batteries, and have the second inverter take the rest of the load. I do have installer access through the Solaredge site but I don’t know how to solve my problem. Can anyone provide some guidance?
