SM2048HE- 2KW 48VDC Solar Charger

Product Overview


SM2048HE Series  2KW 48Vdc Solar Charger Module 

Very high efficiency:   With peak efficiency near 98%, the SM2048HE high efficiency Solar Charger provides significant energy savings. Each charging module is designed for operation with solar panel configurations of one or two strings and with a wide input operating voltage window, offers maximum flexibility so greatest optimization. Module design is based on a high-frequency transformer guaranteeing galvanic isolation between that of solar panels and loads and batteries. Various additional protection elements ensure safety and investment preservation.

MPPT Algorithms:   The SM20478HE includes market leading MPPT algorithms, allowing commencement of solar harvesting far sooner and for much longer than other comparative devices. This combined with the highest conversion efficiency, maximizes PV generation delivering the greatest ROI.

Guarantee Design:   Enatel's solar chargers are New Zealand made to guarantee design, manufacture and process integrity. The SM2048HE represents unrivalled reliability with a robust proven conversion topology. Modules can be integrated into compact solutions or operate as standalone
