Ingo Posted August 19, 2020 Posted August 19, 2020 Can anyone also verify the following in VEConfigure3: 1. Create a new default configuration (12V/230V). 2. Select 'Other' grid code. 3. Select LiFePo4 battery type. 3. Unselect Virtual Switch. 4. Add ESS Assistant with the following settings: 4.1 Select CAN/other BMS 4.2 Enter 200 for battery capacity 4.3 Keep all else default. 5. Now go back to general and notice the Battery Monitor is ON. It should be OFF for the CAN BMS to manage the battery. 5.1 Unselect the Battery Monitor again. 6. Go back to the ESS Assistant and click on Summary. Notice your battery is now defaulted to 10Ah. This is a chicken-and-egg scenario where you now set one value and the other changes and vice-versa. Should I be concerned as this is the exact procedure followed as per the Victron/Freedomwon battery setup guide. I know Freedomwon and Victron spent lots of time integrating their products but the guide that is published does not mention this strange behaviour. Quote
Louisvdw Posted August 19, 2020 Posted August 19, 2020 As for as I understand if you what to use ESS then you need Battery Monitor ON. Also if you can select the grid for where you live, so much better (the SANS one for SA) I use the same settings, except I keep Battery Monitor ON, selected SANS grid and in my case choose Other Battery, cause my LiFePO4 is with 4 cells so the values are different.

Ingo Posted August 19, 2020 Author Posted August 19, 2020 Unfortunately not according to the setup guide below. https://www.victronenergy.com/live/battery_compatibility:freedomwon Quote
___ Posted August 19, 2020 Posted August 19, 2020 Nothing bad will happen if you keep the battery monitor on. All this does is it tells the Multi to keep track of the state of charge. But... 1. You're not using the Multi's SOC anyway, so it does not matter 2. The GX device will write the battery SOC across to the Multi in any case, to keep them in sync 3. If you use any assistants on the Multi itself that uses the SOC (you don't... but if you did), you actually want this to work. Alternatively, you can accept the 10Ah battery capacity. Again, the Ah capacity is needed so that the Multi can track the SOC... but you just told it not to, so even if that value is wrong it is not going to matter. Ingo 1 Quote
Ingo Posted August 19, 2020 Author Posted August 19, 2020 Thanks for the clarification. I'll accept the 10Ah then and stick to the recommendation to disable the battery monitor as per the integration document. It might be a good idea to include that in the integration document so that other users won't get as confused as what I was. Quote
