Please critique my plans
I am planning on self-installing some solar equipment and would like some extra eyes on my plan to make sure I'm not doing something stupid. The immediate needs are a battery bank to protect us from black outs and brown outs (Which are frequent), and to provide us some normalcy in the event of an other Maria. I have picked a battery capacity that should take care of us in both of these scenarios. I also plan on expanding this in the future to our casita, so I want to plan for this as well. I have the ability to add more battery storage and more MPPTs and inverters with this system, which should take care of us for future expansion, I think. Here is what I'm looking at now:
Storage: Fortress Power 16.5kWh Lithium Battery
Inverter/Charger: Schneider XW+ 6848
Panels: 24 Canadian Solar 355W Poly Panels in two strings of 12
MPPT: Schneider XW 80A MPPT (I believe I only require 1, because the total voltage going down the line will only be 12*24=288V, right? And if so, that's well within the parameters of the MPPT)
Conext Gateway, Power Distribution Panel, Genstart, Battery Monitor - The gateway to make configuring everything easier, the PDP to make wiring a lot easier because it has built-in disconnects, Genstart because we have a generator to start, the battery monitor for ... monitoring the batteries
Other: Extra breakers for PDP, wire
1. I am also considering these Peimar panels (https://www.altestore.com/store/productos-solares-en-puerto-rico/pr-paneles-solares/peimar-grid-tie-solar-panels-puerto-rico-p41241/#PR-PEI330P-EACH) because of their lower price and immediate availability (Have to wait on Canadian Solar panels to get here). Thoughts? Worth the wait on Canadian or will the Peimar suit me just fine?
2. The inverter manual suggests that it only be used with battery banks of at least 440Ah, but the Fortress battery only has a capacity of 360Ah. Will this be a problem / Why does the ah capacity of the bank matter here? The manual says that if the batteries fall below 40V that the inverter won't turn on, but the datasheet for the Fortress says that it's minimal voltage is 45V.
3. What's the most foolproof way to make sure I am buying exactly what racking I require? The altE warehouse is quite a drive from here, so I only want to make the trip once if I can.
