Do you have any experience in building bigger systems? I'm thinking about building out something for my home with a roof top solar setup and leadacid batteries, probably in the 4kW range.
Any tips or companies/manufacturers for charge controllers, batteries, inverters, etc that you would point me to?
Yes, I have lots of experience. Look up a guy named Will Prowse on YouTube. He has a ton of tutorials and is my go to for latest and greatest hardware on the market.
