Design Feedback
Engine feedback- Add some loads to size this system.
- Charge controller too small — need ≈ 63 A, have 60 A.

Joe Felz
Licensed builder & electrician. Off-grid solar pro. Founder of Felz Energy Consultants — teaching everyday people how to own their energy.
Joe started with “a $19,000 house and a dream” in 2011, then in 2022 walked away from a 3,500 sq ft home to live fully off-grid out of a 1999 Dodge van — learning solar the way no classroom could: by needing it to work, every single day. His load-first method is the backbone of this lab: start with the load, then size everything else.
The Felz Institute for Solar Energy is an educational training platform — not a substitute for licensed electrical design, permitting, inspection, utility approval, or professional installation. Always verify final system design, wiring, breaker sizing, grounding, disconnects, and code compliance with a licensed electrician and your local authority having jurisdiction (AHJ).
