FAQs

Q: How many solar panels do I need?
Two 300W 18V panels connected in series (total 36V) are recommended for optimal performance. A single 400W panel works for partial output.

Q: Can it run on batteries?
Yes, the pump also accepts 24-36V DC battery input for night-time or backup operation.

Q: Does it work on cloudy days?
Yes, the MPPT controller adjusts motor speed to match available solar power. Output is proportional to sunlight intensity.
