Email jasher_altenor@hotmail.com with any questions, bug reports, or feedback about the app, and we'll get back to you.
Are the sizing numbers exact?
No — everything in the app is a planning estimate. Always confirm your final system design with a qualified solar installer or electrician before purchasing equipment.
Why do I need to enter my email in the Builder?
Unlocking your full inverter/battery/solar recommendation is free — we just ask for an email so we can follow up with more off-grid planning resources, including the Solar Off-Grid Course.
