Why SunMax Optimizers

Developed in partnership with Sungrow — each optimizer ensures every panel performs at its peak independently.

Shade-Proof Technology

Sungrow’s Shade-Proof technology overcomes potential losses at the module level. When one panel is shaded, the rest continue at full output — delivering up to 30% more power generation compared to non-optimized systems.

Rapid Shutdown Safety

Shuts down to just 1V per optimizer (30V system-wide) within 20 seconds. IP68 waterproofing and C5 anti-corrosion rating ensure reliable safety in Singapore’s humid, tropical climate.
