How many 400W solar panel would it take to fully charge (5) EcoFlow DELTA Pro Ultra batteries from 0% to 100% in 6 hours?
You will need at least 13 × 400W solar panels operating at full efficiency to charge (5) EcoFlow DELTA Pro Ultra batteries from 0% to 100% in 6 hours.
⚠️ Important Notes:
Real-world conditions (clouds, panel angle, dirt, temperature) usually reduce output by ~20%.
To be safe, consider adding 15–20% overhead: → 15–16 panels would be more realistic for ensuring full charge in 6 hours.
