Why Choose JST-EXMH-(220-240)W?
Unmatched Efficiency
Up to 20.44% module efficiency (240W variant) - generates more power per square meter than most competitors
24V System Optimized
Vmp (18.60-19.06V) aligns perfectly with 24V battery charging, reducing energy loss
Scalable Design
700Vdc max system voltage supports large-scale series connections for utility-grade or industrial projects
Industrial-Grade Durability
IP67 junction box, 3.2mm tempered glass, and 5400Pa wind/snow load resistance ensure decades of reliable service
FAQ
Q: Can this panel charge a 48V battery?
A: Yes! Wire two panels in series (total ~37-38V) for 48V battery systems (with a compatible charge controller).
Q: How many panels fit on one pallet?
A: 36 panels per pallet (dimensions: 1585*1100*885mm; weight: 420kg).
Q: Is it suitable for coastal areas?
A: Absolutely. The IP67 junction box and corrosion-resistant aluminum frame withstand salt, moisture, and UV degradation.
