I mention this because some are building tiny houses and when space is tight you may end up with just this problem... toilet flange needs to be installed over a floor joist. But not everybody remembers toilets have 2 additional rough-in sizes:
Toilets also come in 10-inch and 14-inch rough-ins.
That bit of knowledge can be a true lifesaver. Let me show you what I meanβ¦

All modern battery inverters which are hybrid types (ie for grid tie in) can control modern AC coupled solar inverters by diddling the 60hz (50hz) line frequency. They do this when they are NOT connected to the grid. The idea is that if the solar inverters are making two much power, the line frequency will ramp up to between 61-62hz and the solar inverters will sense this and ramp their power down from 100% to 0%.
Here's a graph of mine yesterday... as my batteries got full the solar inverter were throttled at 61hz, gradually rising to 62. 64hz is the "everyone stop briefly" signal and my system joined the grid. From there onward you can see the utility grid 60hz varies a little.
Finally in the evening, my SMA inverter disconnected from the grid and did a clock correction by running the house line frequency at 58hz for a few minutes.

This is how AC coupling power control looks in my system. As my batteries near full and my grid tie inverters are making full power, the battery inverter (master clock for the system) starts running the frequency up to attempt to throttle the PV inverters. At 61hz they start to slow power production. As my batteries continue to accept less and less power, finally the frequency is nudged up to 61.5hz. I have an external processor that monitors this line frequency and when it sees 61.5hz it commands my system to grid connect, but that takes 60seconds. During that 60seconds the batteries all but stop taking current and that frequency spikes to 64hz. This shuts off all PV inverters in the house and then the battery inverter can get in phase with the grid and connect without makiing the lights flicker. Within 30 seconds of seeing the frequency at 60hz, the grid tie inverters start ramping up power production and POOF we are selling to the grid.

Why would a person want to use grid tie inverters and AC coupling? Most solar systems installed today are grid tied systems because they are the cheapest. So maybe you already own the equipment!
If you were designing a system from scratch, you might consider AC coupled systems because the inverters are cheaper than the same number of MPPT PV battery chargers.
And finally, you might like the idea of giving the battery inverter a break during the day. You see during the day, AC coupled inverters make the power that runs your appliances directly and your battery inverter sits idle for the most part. In the evening your battery inverter will start running the loads in the house. So that's a 50-50 split right there.

Red Dye #3 is a dye, so it has no nutritional value. It has not been allowed in cosmetics for decades but permitted to be ingested as an unnecessary food dye? Why not ban it first of this month? Why two years? Nothing says you are living in the corporatocacrcy like the government allowing large food companies to continue using a carcinogen.
You know what doesn't contain red dye #3? The tomatos in my garden!
