Intelligent MPPT Charge Limiting without a CCGX

RE: SIMPLE INSTALLATION WITHOUT CCGX

An installer customer of ours has asked if Victron can offer a similar 'intelligent' configuration possible with the Midnite or Outback MPPT and FlexNET DC Shunt combination. With that Outback configuration, the mppt battery charging current limit can be set, and the FlexNetDC shunt will monitor/ensure that limit is not exceeded, but if the inverter supplies a load, the mppt current will exceed the set mppt limit in a controlled manner.

I cant readily see a simple Victron MPPT and BMV Shunt solution, without the addition of a CCGX and then using DVCC.

Thanks

It is possible to have DVCC without a CCGX. You only need Venus OS to be running on something.
What about connecting the MPPT and the BMV to a cheap RaspberryPi and run Venus on that? Then you can use DVCC and most of the other features of a CCXG / Venus GX. You'll even get VRM if you want it, but it's not mandatory to use VRM.

Simple and cost effective.
