Help Completing Our Off Grid Solar

Hi! Last year I finished mounting twelve 250w solar panels totaling 3Kw. These panels are ground based onto a wooden homemade platform that is definitely solar south facing and tillable. I can enclose photos to candidates interested in this project. I ran power cables from the panels to our home, so basically most of the outside work is done (except of course wiring the combiner box so all the panels are properly connected). I also need helpful guidance on grounding everything!! What I would really benefit from is help with is finalizing decisions on an inverter, a charge controller, batteries, etc. and good instruction on how to wire everything. With respect to batteries, I'm only interested in lead acid, they're time proven with their durability, environmentally friend and a long lifespan. I can detail what our power needs would be when we speak. Thanks, Alex :) Apply tot his job
