Capacity

[Scheppo]

The Capacity is not showing in aggregator Battery, only the installed capacity:

Maybe the System need it?

Issue here is only the CAN battery provides capacity for the 280ah battery. No way to know the current capacity of the 120ah battery. What I could do is take the total capacity to be soc * installedCapacity if that is good enough?

When the System don’t want this value then you don’t must do anything.

ps: The 120Ah Battery has also a Can-Bms, I will try to connect it to the ve-can bus. When this works, I can tell you and maybe I can do same with 120ah battery like 280ah battery.

Config should be:

{
"capacity": 400,
"virtualBatteries": {
"com.victronenergy.battery.V280AH": ["com.victronenergy.battery.ttyS5", "com.victronenergy.battery.socketcan_can1"],
"com.victronenergy.battery.V120AH": ["com.victronenergy.battery.ttyUSB1", "com.victronenergy.battery.socketcan_can0"]
}
}

Wow, it works! Maybe anybody will do the same, here are my Systemconfig: Cerbo GX 2* 48V Battery’s parallel connected. Battery 1 - 280Ah, Seplos Can-Bms over GX-Can-BMS and Smartshunt connected. Battery 2 - 120Ah, China-Bms over GX-VE-Can and Smartshunt connected. Batteryaggregator do the following things: Make Virtualbattery1 = Battery1 with Volt, Ampere and SOC Data from Smartshunt and other Data from Can-Bms. Make Virtualbattery2 = Battery2 with Volt, Ampere and SOC Data from Smartshunt and other Data from Can-Bms. Then aggregate the 2 Virtualbatteries to one 400Ah Battery used as Batterymonitor.

I hope I explained everything correctly. if not please correct.
