No rule fires for this kit in Minneapolis in December. The result is waiting for manual review before we call it a pass.
The kit contains 1 × EcoFlow DELTA 3 and 1 × EcoFlow 160W Portable Solar Panel (EF-Fold-P160-04). The maker does not publish how the panels are wired, so we check the layout a 12 V controller can start on with the fewest panels in series: 1 in series × 1 strings.
What fails, and where
In all three: Phoenix (warm, December), Denver (moderate, December) and Minneapolis (cold, December): 33 of 34 pass
- Worth knowing
The panel and station connectors differ, so you need an adapter.
Show the numbers
You need an adapter from MC4 to XT60; it's added to the parts list.
A year with this kit in three climates
Across the nine runs the same kit goes from no blackouts (garage in Phoenix) to 365 days without power (cabin in Phoenix). The hardware is identical in every run. Only the weather and the load change, so a review from one location says little about yours.
