Ingress Protection Rating - IP65

This product can be installed at a distance of 500 m or more from the shoreline.

The W73A features superior waterproof and dustproof performance with an IP65 protection rating.

No malfunction or performance reduction was observed after this testing under an environment equivalent to salt damage areas. Note: Exterior discoloration and rust will not be covered by warranty.

Output power factor can be set between 0.8 and 1.0 in 0.01 increments.The rise in grid voltage can be easily suppressed by adjusting the power factor.

The standard 1-year warranty can be extended to 10 years as needed (with charge). Warranty conditions are contained in our terms and conditions.
