There are due to the firm two highlights. Firstly, of all the user interfaces has been improved: the overview better adapts to the installed system. And behind each entry in the device list, you can now see the main parameters. Secondly, v2.00 marks the release of an ESS, short for Energy Storage System. This is a result of experiences learned from the Hubs.
The ESS is a combination of standard multipurpose Victron products, together configured for ESS. In the system, there must at least be one inverter/charger and also the CCGX. The Multi or Quattro is configured with the ESS Assistant. ESS can work with Energy Meter (like Hub-4 did), or without (like Hub-1 and Hub-2 did) feed power from MPPT Solar Chargers back to the grid (like Hub-1 did) or not.
Victron has combined all options in one, simplifying setup and configuration. Also, ESS has several new features, and it is much easier to understand how it works and why it is doing what it is doing. Most of the Hub-1 and Hub-2 policies are now deprecated for new installs, as is the Hub-4 Assistant. For exact details see the Comparison chapter in the ESS manual.
Besides those two major changes, there is more:
- improved genset start/stop
- remotely restarting a Multi or Quattro system if it has locked out
- eliminating the need for a BMV in simply Multi and MPPT solar systems
- better LAN/WiFi network stability
- improved CCGX firmware update mechanism
- and still more
