Is these settings in the ESS manual to use a Fronius Smart meter just to send data to Solar Web?
In other words: to run a Smart meter in series with a Carlo Gavazzi (Smart meter just to send data to Solar.Web)
So the Fronius PV inverter will not control the export limiting, but it would be done through the Multiplus.(ESS assistant) Do I need a Carlo Gavazzi meter to control ZERO export to the grid if all the loads and the PV inverter are on the output of the MultiPlus II?
4.3.11. Zero or limited feed-in
ENABLING GRID FEED-IN
On the Victron GX device - In the ESS -> Grid Feed-in menu, there are seperate options to enable:
AC-coupled PV - feed in excess (default disabled)
DC-coupled PV - feed in excess (default disabled)
Enabling either of these options will expand the menus to give the further options:
Limit system feed-in (default disabled)
Maximum feed-in (in Watts)
Feed-in will only occur if there is sufficient surplus PV production to fully supply the loads, and the battery is charged (or at it's charge current limit).
Note: The limit system feed-in is a system target, and under some circumstances such as large load disconnection, or sudden increase in solar production, it may be exceeded momentarily until the system is able to regulate the inverter output back to within the target limit.
AC-COUPLED PV - ZERO AND LIMITED FEED-IN WITH FRONIUS AC PV
The AC-Coupled PV zero or limited feed-in feature is specifically designed and most rigorously tested with Fronius AC PV inverters.
The earliest Fronius firmware version which can be used is 3.7.3-2
If there is more than one Fronius PV Inverter present in the system, they will all be limited
Zero feed-in is not supported on Fronius IG Plus inverters.
Change the following settings in the Fronius web interface:
In the Fronius setup menu, set Data export via Modbus to tcp.
In the same menu, set Sunspec Model Type to int + SF
In Settings→DNO Editor, make sure dynamic power reduction is set to No limit (this is the default).
In Settings→DNO Editor, make sure that in the 'Controlling Priorities' section that 'Controlling via Modbus' is set to be priority 1.
Then double check that all above criteria are met. It will show Feed-in limiting active No if the firmware requirement; the Data export; or the Sunspec Model type settings are incorrect, or the units are shut down (no available PV), or AC-input is disconnected / unavailable.
When working correctly, Feed-in limiting active will show Yes
Do not use a Fronius Smart Meter for limiting export when part of a Victron ESS System. More details about when a Fronius Smart Meter can, and can not, be used is explained
