The second hardware revision of the IP22 is now supporting VE.Smart networking. It looks like Victron fixed the "too small microcontroller" issue in that revision. That is pretty cool!

There is a guy here that reports it is working for him.

When I look at the release note, see "Blue Smart Charger" section of the v5.42 release, I have few questions about synchronized charging of an IP22 and a Smart Solar MPPT unit. It is said the IP22 will become the charge master in a VE.Smart network. That makes sense. However, even if the charging profiles are configured identically on both IP22 and MPPT, only IP22 supports a storage phase in its charging cycle.
So, what happens to the MPPT when the IP22 switches to storage phase of its charge cycle at the end of a long sunny day? Similar use case, what happens to the MPPT if the IP22 is already in storage phase when at the beginning of day? Does it mean it require the storage voltage of the IP22 must be set the the same value of float voltage? What happens if it is not the case (storage voltage lower than float voltage)? Is there any plan to add support to a storage phase in the charging profile of MPPT?
