6 x 370W = 2220W (STC) of panels, might make 1800W under typical conditions mid-day. Might make 10.8 kWh on an average day.
That's not quite enough to fully charge one PowerPro from empty, assuming no loads. Including no inverter idling 24/7.
Your HVAC unit, 12A @ 240V, is 2880W. Maybe you could get 3 hours or so a day operation from that amount of panels.
You want much more panels to supply the house during the day, and charge battery enough for the night.
Panels are CHEAP! Mounting hardware costs more than panels Labor costs even more.
I think 18kPV is meant to take up to 18kW of PV production, supply up to 12kW of loads from PV and/or battery, charge batteries while powering loads from PV. (Give or take, I don't remember the exact specs for that unit.)
2kW of panels would be suitable for a much smaller system, like a small RV.
You need to understand your total load, kWh/day summer and winter, max kW draw, peak kW including starting surge.
Good that you got "48A LRA", puts you way ahead of most visitors.
48A x 240V = 11,520VA starting surge. Yes, 18kPV is suitable for that.
The price $10k is about in line with the inverter, battery, panels. Anything else come for the price?
For $2000 I bought 10kW of panels not long ago. Prices are amazing these days.
"Plus installation" - What is probably most important for you to know is that installation is not available. You can't buy it anywhere.
Your choices are to make a Faustian bargain to purchase an installed system, with the installation company bundling in the equipment, or else to buy the hardware and do 100% of all labor yourself. If you are able to identify and manage people as your employees (and I highly recommend buying suitable insurance such as Worker's Compensation if you do), then someone else's labor could work.
is there a useful online tool to size the solar system for your house based on electricity bill ? I have been searching and the ones i used should a large number of solar panels
