I also have several quad XW stacks out there so am familiar with the challenges. As it happens, two of the inverters at this time are offline and breakers open, I should have specified that. So the system is actually working as a dual XW presently. During testing the master inverter was online and the slave in standby.
As for battery cables, I have 2 pairs of 4/0, twisted, each feeding two inverters through a PDP. Customer reports they have a second leaf blower of another brand that works fine. I have suggested just replacing the problematic unit with one we know works, as chasing this down could eat up a lot of time.

I've been there twice. I think the issue has to do with four of those inverter transformers in parallel creating a large Inductive load that gets owned by the inductive load of the reef blower. I guess you could add prescribed AC capacitor to the reef blower and the issue goes away. LEDs lights are likely large series strings of direct AC coupled voltage drop loads and any gap gets displayed.

New building site, cycle charging with generator presently until next year for PV installation. Construction crew of ~15 has been running flawlessly off this system for 6 months with every kind of power tool. 3 buildings serviced from a centralized power shed. Homeowner adds a Black & Decker BV6000 leaf blower and problems arise. The blower starts fine, but most of the LED lights in the facility will flash on and off twice when the blower starts up. Not a flicker, but an off/on cycle about 1s each. This behavior extends to other buildings that might be 500' away. Works fine when running the generator in charge mode (therefore gen powering loads directly). Testing this same leaf blower on my own single XW6048 system, with LED lights, and cannot replicate the issue. Even a small 2kW mod sine inverter in my service truck runs it fine. I will put a call into Schneider but am not holding breath for help there. Any ideas?
