we have:
2440w PV
12K hybrid controller
300AH FLA @ 48v

it is sufficient to power our home entirely during solar hours. we generally draw between 450w to 1200w throughout the day. even though we only have 2440W PV, it is able to pull from batteries if we exceed PV production.

our system is grid-tied, but DOES NOT EXPORT to the grid. this allows us to import power during PV shortfalls or overnight, so we do not cycle our batteries, leaving them charged and ready for a grid outage.

ROI estimated at 13-15 years, at current investment & current capacity. it is NOT about "free electricity" or "getting my money back" it is about having resources when others don't. in the 8 months since install at the new farmhouse, we have had 3 power outages that would have resulted in food loss, not to mention simple inconvenience. we're talking about 2x 4.5 cubic meters of frozen farm & game meat, not to mention the kitchen freezer/refrigerator.

we built this house for maximum power efficiency, having already owned and operated the solar power system at our old, suburban house. Mini-splits, heat pump water heater, grundfos10 well pump, all LED, wood heat & cooking backups, propane main kitchen oven/range. spray foam insulation, zip board & tape construction.

on top of all that, we are just observant of our power consumption.

next upgrade will be a 300AH LiFePO4 trophy battery. eventually, after that, we will focus on PV upgrade/expansion. we have dual MPPT input, so we can run two independent, dissimilar arrays, while still getting full functionality on both.

All DIY installed. every panel, battery, rail & screw. shiiiiiiit.... we even built the shed it's mounted on/in.
