48V 1KW brushless, 300W monocrystalline solar array, 1200Whr 12V SLA battery, 4x 14.8V 8Ah LiPo array (charged to 60V as the capacitor's max rating was 63V), 2x MPPT to charge the 60V battery array from 12V, recycled rebar and mountain bikes. I completed this project in 10 days from extra parts and materials I had laying around.
