DRM0, DRM5, DRM6, DRM7, DRM8 are available.
Damage to the inverter due to moisture and dust penetration
Ø
Make sure the cable gland has been tightened firmly.
Ø
If the cable gland are not mounted properly, the inverter can be
destroyed due to moisture and dust penetration. All the warranty
claim will be invalid.
Information
CAUTION
WARNING
Excessive voltage can damage the inverter!
External voltage of DRM PORT don't over +5V.

Operate the disconnection device.
Do not generate power.
Do not generate at more than 50% of rated power.
Do not generate at more than 75% of rated power and
reduce the reactive power as far as possible.
Increase power generation (subject to constraints from
other active DRMs).
