Technical FAQs 4

Do all solar inverters support DRM 0?

So while support for all demand response modes is not currently mandatory, all inverters are required to support demand mode DRM 0 (which disconnects the inverter when the signal is received). Why would a solar system owner be interested in implementing DRM functionality?

What does DRM stand for in a photovoltaic inverter?

In photovoltaic inverters, DRM stands for Demand Response Management. Solis inverters include a remote shutdown feature, enabling the inverter to be powered on or off remotely using logic signals. The DRM port is equipped with an RJ45 terminal, where Pin 5 and Pin 6 are designated for the remote shutdown functionality. Example RHI- (3-4.6)K-48ES-5G

Are inverters DRM compliant?

In response to the new standards requirements, some inverter manufacturers have redesigned their inverters to incorporate full DRM functionality. These inverters are referred to as DRM ‘compliant’, and within the AC Solar sector, Enphase Energy inverters are currently the only fully compliant microinverter available.

Do inverters comply with demand response modes (DRM)?

Context According to an Australian standard, the inverters must comply with demand response modes (DRM). Figure 6-43Wiring diagram for the DRM function Table 6-3DRM requirements Mode Corresponding Port on the SmartLogger Requirements Remarks DRM0 AI2–AI4 When S0 is turned on, the inverters shut down.
