Switching question: x6000 system/solar/generator/grid transfer switch question:

[rgsherr]

I currently have a Yamaha inverter generator and an Anker F2000 generator both connected with separate cables (one at a time) into a Protran transfer switch. I just unplug one and plug the other into the transfer switch when the power goes out depending where I want to draw power from. When the grid goes down I plug the anker into the Protran, turn it on and run essential circuits from the Anker until the battery runs down, then unplug the Anker, from the transfer switch and plug in the cable from the Yamaha. turn it on and run essential circuits from that until the Anker is charged up, then unplug the Yamaha from the transfer switch, plug in the cable from the Anker and use it till either the grid comes back on or the Anker's battery runs down. By just using the Anker most of the time when the grid is down, it reduces the amount of gasoline I need to stock. Thinking of adding some solar panels, batteries and an x6000, and solar panels to this setup in place of the Anker which would give me a potentially more powerful system. Wondering if the EG4 x6000 system can be connected and work in the same way as the Anker and so use the grid as long as it's working and charge the batteries either from the grid, the Yamaha generator or solar? Or maybe even keep the Anker and tie it in too.
Hope this is not complete nonsense, but I guess posting this is the only way I'll find out. As you can see I'm a complete solar newbie.

With batteries, sure. But better.
I don’t know- don’t have one- but often equipment at this level will run batteryless as well. But by adding bat least 10kWh of batteries a couple things happen:
1) you can probably run all day and maybe all night with a ‘just barely’ system like this. 2) your electwickill bill gets cut down to maybe nothing if set to “SBU” and it will automatically switch back to grid bypass if batteries get low during normal operation. So no risk (s)
3) by daily-usage of the system you will eventually get a return on investment. So by making a useable system it becomes an investment rather than an expense- and comparatively quickly if DIY.
