Hi all! I'm new here and we're getting ready to start the process to get solar for our home, as both back-up for power failure and also powering some of what we use on the solar to reduce electric bills. We do not want a grid-tie as it provides little to no benefit for us, rather this will be a system we build as "off grid" that can also charge via AC power if needed.
Looking at our current usage, we want a system that we can expand over time, but have enough in place initially to cover our basic needs in the event of a power failure. Currently our usage is high (don't judge, it is what it is) at an average 74.5Kwh a day, or 2,236Kwh a month. Our peak use is 3,057Kwh in a month, our low use is 1,609Kwh in a month. I got these numbers by reviewing our 2020 usage, month by month.
I am looking to start with 2 BigBattery TREX (12.8Kwh) that will give us 25.6Kwh of power in batteries; they're 48V batteries. Over the next few years we'd likely look to expand that up to 102.4Kwh stored.
I'm trying to decide on whether I set up 2 MPP Solar LV2424 or 2 LVLV6048 controller/inverter boxes. I'm also trying to understand if I'd need to continue adding boxes in the future with additional batteries added over time.
I'm also trying to figure out our best option for solar panels...for our future needs, it's an insane amount of panels needed!
More importantly, I'm trying to figure out if the controller/inverter boxes can also have wind turbine energy as an input - where we live (central midwest) we have great sun from April to October, then consistent breezy wind from November to March, along with wind all year even in the summer months, especially when we're having our spring storms....so I'd like to look at options to add a wind turbine (or multiple turbines), but information is scant on how I can add that to a solar system to get power from both sun and wind. Does anyone have any good information on how to do this, or where I can look to better understand how to create a hybrid system.
What I've been looking at above is just the basics, I'm open to using different products if they're going to better meet our needs for our initial system and later expansion.
Thanks for your help!
