VRM Portal<\/a> and alarm emails.<\/p>\nAlso, the high DC ripple alarm is now shown per phase.<\/p>\n
Remotely restart a Multi or Quattro system after it locked out<\/h3>\n
Use this option to restart a system once it has locked itself out. This means it’s no longer required\u00a0to switch all units off one by one and then switch them back on again by using the rocker switches on the Multi or Quattro.<\/p>\n
Also, using Remote Console, this can now be done remotely!<\/p>\n
Further improved CCGX synchronisation options<\/h3>\n
1: removed the Synchronize VE.Bus SOC config option<\/span><\/p>\nThis user setting has been removed: there is no need to set it manually as the CCGX will now activate it automatically when it detects that there is a Multi or Quattro installed, and an external battery monitor.<\/p>\n
2: eliminated the need for a BMV in a simple Multi + MPPT solar system<\/span><\/p>\nTo get proper state of charge\u00a0reading for the battery, it used to be necessary to install a BMV for systems with MPPT Solar Chargers.\u00a0Not anymore: the CCGX will continuously inform the Multis or Quattros about the MPPT charge current, which is then used in the SOC algorithm.<\/p>\n
It is not necessary to enable this feature: it is automaticall<\/p>\n
3. Synchronisation mechanisms are now visible<\/span><\/p>\nAbove two explained mechanisms, as the Solar charger voltage control one (used by ESS and Hub-1), are now visible in the System setup menu:<\/p>\n

ESS\u00a0– Zero feed-in with a Fronius PV Inverter<\/h3>\n
The ESS system can control the Fronius Power Reduction feature, resulting in a nice zero feed-in system. Herewith, it is no longer necessary to use the Prevent feedback option of the Hub-2 Assistant. By staying connected to the grid, instead of switching back and forth to inverter mode, flickering of lights, and also the occasional (avoidable) overload shut down are now eliminated.<\/p>\n
Before I go on and explain how to set this up with a Fronius, first I’d like to discuss doing this for other brands of PV Inverters: I have come across several installations where Hub-2 with “prevent feedback” is used, and were having problems. Lately, I started to take a step back: instead of diving into the details; I first asked why the system is setup like that? Two often heard reasons are:<\/p>\n
\n- “The utility doesn’t pay me for the feedback”
\nWell, so what? If they do allow it, while not charging you for feedback and also not disconnecting you, please just let the PV Inverter do its feedback. The system will be more stable: no switching back and forth to inverter mode.<\/li>\n - “Even for small systems I prefer a PV Inverter over an MPPT Solar Charger”
\nThough everyone is free to prefer one solution over another, I do recommend strongly to reconsider: technically, preventing feedback of a PV Inverter by going into inverter mode and starting to frequency shift, can be done. But the technologies used, switching back and forth to inverter-mode and\u00a0altering AC frequency, are not ingredients that help in creating a stable and smooth running power system. While that (a stable and smooth running power system) is what\u00a0the end-user of such a system is used to.<\/li>\n<\/ol>\nThis is how the settings on the Fronius need to look:<\/p>\n

<\/div><\/p>\n
Notes:<\/p>\n
\n- Minimal required Fronius firmware version is\u00a03.7.1-5<\/strong><\/li>\n
- After boot of the CCGX, it might first charge the battery with ~500W for a minute or so.<\/li>\n
- If the Int + SF setting is not available in the Fronius PV Inverter, you need to update its\u00a0firmware to a more recent version. Contact Fronius.<\/li>\n<\/ul>\n
The feature can be enabled in the menu Settings -> Energy storage system.<\/p>\n

<\/div><\/p>\n
Once up and running, the Fronius entry in the Device list shows the actual power limit of the inverter:<\/p>\n

Generator start\/stop improvements<\/h3>\n
![\"genset-startstop-do-not-run-genset\"](\"https:\/\/www.victronenergy.com\/blog\/wp-content\/uploads\/sites\/10\/2016\/11\/genset-startstop-do-not-run-genset_24860983.png\")
<\/div><\/p>\n
There is a new feature: “Do not run genset when AC 1 is in use”. It\u00a0is intended for backup systems, with a Quattro, having mains on AC in 1, and Genset on AC in 2. When this option is enabled, the Genset will only be started after a mains failure. And in the case of a mains failure, the Genset will automatically be stopped again as soon as the mains is restored.<\/p>\n
Also, there are now multiple measurements for the AC load condition that can be selected. There are three options to choose from:<\/p>\n
\n- “Total consumption” <- This is the value that was used in previous versions<\/li>\n
- “Inverter total AC out”<\/li>\n
- “Inverter AC out highest phase\u201d <-\u00a0Much better for split- and three-phase installations<\/li>\n<\/ol>\n
