Looking for Suggestions - 200amp panel with 125amp subpanel for Pool

[iamrm]

Currently on order:
2 x F3800 Anker Solix
2 x BP3800 batter pack for F3800 Anker Solix
1 x Smart panel from Anker for automated transfer

Current setup:
200amp panel that powers the home
125amp sub-panel from the main panel that powers the outdoor kitchen/pool hardware (heaters , pump etc)

Current Plan:
Get the 2x F3800 setup with the main 200amp panel via a subpanel for 50amp for important circuits from the main home for emergency backup.

Problem (This is what i'm looking suggestions for):

One of the main reason to buy this stuff was that incase we're not home and temps drop below freezing and we loose power, I want to make sure that the pool/spa pumps (jandy VSP - require ~300w) running to ensure pool/spa plumbing doesn't freeze.

However I'm not able to figure out how this setup would work, since the pool pumps are powered off the 125amp subpanel that's on the other side of the home.


Any suggestions/recommendations are more than welcome.
My main goal out of this setup is to essentially run fridge / freeze / few home circuits for wifi etc AND pool pumps to prevent freezing of plumbing.

Eventually will setup some Rigid Solar panels to connect to the F3800 to charge via solar as well.


More than happy to answer any questions/provide more information.

I put up some panels, and 2000w inverter, and I have a Pentair variable speed pump, and a small 200 amp power 12 V battery. It has been working great. It does not get freezing here. I also have a spare Jandy 240 V pump that is like your as variable speed. But I don’t have a bigger 240V inverter yet. For me it was cheaper to replace my pump with 120 V and buy a lower cost inverter than to go all in and do a big system. As long as the sun is out, I can run the pool pump for about 5 1/2 hours at 2400 RPM and still maintain hundred percent state of charge. If I run the pool much longer than that, within three or four days, the battery will be dead. It is taking me months to figure out what speed I can run things out and how long I can run them. Every time I increase my timer on my variable speed pump by 15 minutes. If I have two days of clouds and rain and I try to run my pump, I will definitely have a dead battery. If you decide to go this 12 V route, I recommend you get more batteries or a bigger bag or even what I have. If I were to do it again, I would get four matching batteries that have Bluetooth in them, run them in parallel, And then when I’m ready to go to 48 V connect them in series.
