Alarm code: 2018.
Description: DRM Connection Failure.
Troubleshooting:
Confirm whether DRM cable connection has been properly wired.
This is a general explanation about DRM Function:
In photovoltaic inverters, DRM stands for Demand Response Management. It's a function that allows the inverter to automatically adjust its power output based on signals from the utility grid. This can be beneficial in several ways:
Benefits of DRM:
- Grid stability: By responding to grid requests to reduce or increase power output, inverters with DRM can help stabilize the grid, especially during peak demand periods or unexpected fluctuations.
- Cost savings: Utilities may offer incentives to homeowners or businesses with inverters that can participate in DRM programs.
- Renewable energy integration: DRM can help integrate more renewable energy sources into the grid by ensuring that they don't overload the system.
- Environmental benefits: By reducing reliance on fossil fuels during peak demand periods, DRM can help reduce greenhouse gas emissions.
How DRM works:
- The inverter receives signals from the utility grid through various communication protocols like Zigbee, Ethernet, or cellular networks. Solis Inverters use Ethernet (attached you will find connector port and diagram for daisy chain).
- These signals may request a reduction or increase in power output.
- The inverter adjusts its power output based on the received signals and its internal algorithms.
- Some inverters offer various settings to customize DRM behavior, such as minimum power output or response time.
Things to consider:
- DRM participation may be voluntary or mandatory depending on your location and utility provider.
- Not all inverters have DRM functionality. Check the inverter's specifications before purchase.
- Participating in DRM may affect your solar energy production and self-consumption.
