EcoFlow DELTA Pro 3: solar specs and wiring limits
What are the EcoFlow DELTA Pro 3 solar input limits?
EcoFlow DELTA Pro 3 solar limits: High-PV Input accepts 30 to 150 V at up to 15 A, and Low-PV Input accepts 11 to 60 V at up to 20 A. Total solar input peaks at 2,600 W. Stay inside that window on your coldest morning, because voltage rises as panels cool and exceeding the maximum can damage the station.
