This roof needs a confirmed installation layout. Enter a complete measured cable route below, or send your measurements for help.
Valleys & extra cable routes

Measure each separate cable route
Plan real start and end points near suitable power. Each route must fit an available pre-assembled length. Include returns and travel to power; do not simply divide the total evenly.
Check a cable specification If you already know your power requirements.
These are values to check, not a product recommendation. Choose your cable specification on the product page. Changing voltage suggests the usual connection; you can adjust it.
Confirm start-up conditions You can leave these for YeloDeer to review.
Use the coldest start-up condition, including after an outage. Separate outlets can share one circuit. A larger breaker does not increase a controller’s 15A rating.
