Inverter Demand Response Modes (Drms) - Growatt MOD TL3-XH Series Installation & Operation Manual

6.8 Inverter demand response modes (DRMS)

This series inverter has the function of demand response modes, We use 16-Pin
socket as inverter DRMS connection.
DRMS application description
Ø
Applicable to AS/NZS4777.2:2015 or Commission Regulation
(EU) 2016/631.
Information Ø
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
CAUTION
warranty claim will be invalid.
Excessive voltage can damage the inverter!
External voltage of DRM PORT don't over +5V.
