One set of panels, two different inverters in 2 locations

I am trying to attach two different inverters to the same solar panels. The inverters are in different locations (house and 100ft/30m away shed). On paper, i have enough production for both inverters. However, only one inverter at a time sees the panels. The solar cabling is in parallel between the 2 devices.
One is a growatt 3k off grid, the other is a MrWatt same specs.
What am I doing wrong? Is there electronics that stops seeing the panels?

This does not work. The inverters will slam dance with each other as they seek MPPT.
Each SCC needs its own array.

What does your array consist of? Maybe it can be split between the 2 SCCs.
Omg, that's so logical. Didn't think of MPPT. Was considering the panels as stable power source and the inverters as stable loads.
Crap.
The back shed needs are extremely variable and don't justify the dedicated 1/3 of the panels for peak usage. Sending ac power from main house will require digging a trench and metal tubing...
Wonder if over the air ac cabling is code ...
Thanks again , really clarified
