Hello everyone,
after the release of v1.28 for the Multi RS 6000 I did some testing and here are my findings disabling charging and grid feedin.
Used versions and configurations:
- Multi RS 6000 firmware v1.28 in 3 Phase configuration
- Victron Connect v6.30 Beta 8 (MacOS)
- Cerbo GX MK1 firmware v3.70~83
- Node-Red palette v1.6.59
- There is no external control system (ImSys) installed yet
- Testing was only done by switching the VC Aux settings to on/off
Testing to disable feedin (§9)
Setting “Use Aux1 as disable FeedIn signal” to “Aux input active” correctly triggers the message “Feed-in not active” in Victron Connect. I was not able to test it fully because there was not enough solar production that day.
Findings:
- There is no clear indication on Cerbo that the Feed-in is disabled
- There is no clear indication on VRM that the Feed-in is disabled
- Node-Red “RS6K-L1 > Disable Feed-in” stayed at 0 (Feed-in enabled)
- Node-Red “RS System > Disable Feed-in (into grid)” stayed at 0 (Feed-in enabled)
Testing to disable charge (§14a)
This was simulated by setting the minimum SOC to 100% with 50% charged battery. The battery charge went up to around 15 kW and was correctly limited when “Use Aux2 as limit charger signal” was set in Victron Connect.
Findings:
- There is no clear indication on Cerbo that the charge was limited
- There is no clear indication on VRM that the charge was limited
- Node-Red “RS6K-L1 > Disable charge” stayed at 0 (Charge enabled)
- There is no “RS System > Limit Charge (from grid)” option in Node-Red
Recommendations:
- There should to be a clear visible indicator on Cerbo and VRM for both scenarios
- The nodes in Node-Red need to be functional and report the correct status
- There should be an option to send alarms when either “Limit charger” or “Feed-in disabled” is triggered
Thanks and kind regards
Stefan
