-To make sure that the Fronius PV inverter works well with Victron inverter/chargers, both must be configureren with the right 'frequency shift settings'. //[To do add a few lines to explain what ac frequency shifting is and what it is for, including link to factor 1.0 rule page. Some snippets: makes the Fronius PV inverter limit its output power based on the AC frequency.See the following graph, with the frequency on the X-axis, and the maximum output power as a percentage]//
+===== Frequency shifting =====
+To make sure that the Fronius PV inverter works well with Victron inverter/chargers, both must be configured with the right 'frequency shift settings':
+  * The Fronius PV Inverter must be set to Setup MG, short for Micro-Grid.
+  * For off-grid systems, load the Multi or Quattro with the PV Inverter support Assistant
+  * For on-grid / energy-storage systems, load the Multi or Quattro with the ESS Assistant. Read information about ESS in the [[ess:design-installation-manual|]].
+And the [[ac_coupling:start|1:1 limit rule]] must be adhered to.
 ===== Fronius / Victron specifics =====
-With a Fronius PV inverter this is a very easy setup. The Fronius Setup MicroGrid (MG) has been developed in close cooperation with Victron Energy. Simply order the PV Inverters with option Setup MG 50 (for 50 Hz systems) or Setup 60 for 60 Hz systems. Everything is then preconfigured. The MG Setups have all the necessary settings preconfigured, and match the default Victron Assistant settings, such as:
+This is a very easy setup. The Fronius Setup Microgrid has been developed in close cooperation with Victron. During commissioning, set the PV Inverter to Setup MG50 (or Setup MG60 for 60 Hz systems). Everything is then pre-configured. The Setup MG settings match the default Victron Assistant settings.
-  * Tolerant voltage and frequency boundaries
-  * Disable Anti-Islanding detection
-  * Frequency dependent power reduction according to the graph in the [[http://www.fronius.com/cps/rde/xbcr/SID-F75BE891-A018D2F4/fronius_international/SE_DOC_FLY_MicroGrids_GridFormer_EN_326404_snapshot.pdf|MicroGrid flyer]] (Starting at 51 Hz with a droop of 60 %/Hz, so at 52.8 Hz the power = zero and the inverter disconnects at 53 Hz)
 Compatible inverters are:
-  * Fronius IG Plus V (1~, 2~, 3~, 2.5 kW up to 12 kW) -> from IGF 5.0.66 on with settings according to the VICTRON recommendations.
+  * Fronius Primo (1~, 3 kW up to 8.2 kW) -> Software //fro27140.upd// or higher (see FAQ Q5!)
-  * Fronius Galvo (1~, 1.5 kW up to 3.1 kW) -> use latest FW
+  * Fronius Symo (3~, 3 kW up to 20 kW) -> Software //fro27140.upd// or higher (see FAQ Q5!)
-  * Fronius Symo (3~, 3 kW up to 20 kW) -> use latest FW
+  * Fronius Eco (3~, 25 kW or 27 kW) -> Software //fro27140.upd// or higher (see FAQ Q5!)
-  * Fronius Primo (1~, 3 kW up to 8.2 kW) -> use FW that will be available next week (week32)
+  * Fronius Agilo (3~, 75 kW up to 100 kW) -> Software //update19.tl// or higher
-  * Fronius Eco (3~, 25 kW up to 27 kW) -> use latest FW

-  * Fronius Agilo (3~, 75 kW up to 100 kW) -> use latest FW
-Recommended for new systems are the SYMO inverters for 3~ systems and PRIMO inverters for 1~ systems. Do note that these products topology is transformerless and therefore PV-Modules that need to be grounded cannot be connected.
+For new systems the Symo and Eco inverters are recommended for 3~ applications. The Primo inverters are recommended for 1~ applications. Please note that all these inverters are transformerless and therefore PV-Modules that require pole-grounding (on the Plus or Minus pole) cannot be connected.
-In case of PV modules that need to be grounded, use inverters from the IG Plus V series or Fronius Galvo inverters.
+The use of Fronius Galvo inverters is not recommended anymore for new applications - the Fronius Primo is the best substitute and offers higher efficiency, wider DC voltage range, two MPP trackers and many other features.
-When setting up a system, always update both the Fronius and the Victron devices to their latest versions.
+When setting up a system, always update both the Fronius and the Victron devices to their latest firmware versions. For the latest Fronius firmware and information how to update use this link:

+===== Setting up the Fronius with Setup MG50/MG60 =====
 When not pre-ordered with a MicroGrid setup, follow these steps:
-  - Make sure that the Fronius PV inverter is updated to at least the firmware version mentioned above. See table above.
+  - Make sure that the Fronius PV inverter is updated to at least the firmware version mentioned above. See Inverter list above.
   - After making the inverter operational according to the manual, select the language and after this the country specific setup.
   - Here choose MG50 or MG60 depending on the system frequency.

+| Start| 51.0 | 60.2|Hz|
+| Minimum| 52.7 | 62.7|Hz|
+| Disconnect| 53.0 | 63.0|Hz| \\
-=== Why doesn't the frequency settings in the Multi and the Fronius need to be the same? ===
+More information on adding Assistants is [[assistants:how_to_add_and_configure_an_assistant|here]].
+===== Remote system monitoring =====
+The Victron system can be monitored through Victron VRM Portal if a [[https://www.victronenergy.com/panel-systems-remote-monitoring/color-control|Color Control GX]] is present at the site.
+The Fronius PV inverter data can be [[ccgx:ccgx_fronius|integrated into the Color Control GX]]  and therefore also in the VRM portal.
+So the VRM portal is the recommended monitoring platform also for AC-coupled installations.
+However, also Fronius offers an equivalent monitoring solution. The Fronius portal is called Fronius Solar.web. The PV system data can be transfered to the portal if the inverter is equipped with a Datamanager 1.0 or Datamanager 2.0.
+The usage of both portals in parallel is possible.
+A video instruction how to set up the Datamanager 2.0 + Solar.web can be found [[https://youtu.be/u_DX7PmHPXQ|here]].
+===== Zero Feed-in =====
+It is possible to make a Zero feed-in system with Victron & Fronius. The Venus device will the control the Fronius output power. See the [[ess:design-installation-manual|ESS manual]], chapter 4.3.11 Fronius Zero feed-in for details.
+===== Frequently Asked Questions =====
+==== Q1 Why doesn't the frequency settings in the Multi and the Fronius need to be the same? ====
 The first two frequencies do not need to be the same since the Multi actively regulates.
-=== I have an Fronius IG inverter (not Plus), can that work? ===
+==== Q2 I have an Fronius IG inverter (not Plus), can that work? ====
 No, the IG inverters cannot be made to work in a MicroGrid system. The appropriate substitute for an IG 30 is the GALVO 2.5-1 or an IG Plus 25V-1 (depending on the desired DC voltage range).
+==== Q3 The system is locked to 53 Hz and does not resume ====
+See [[:assistants:pv-inverter-support#q1_the_system_is_locked_to_53_hz_and_does_not_resume|here]].
+==== Q4 Can I use the Fronius Smart Meter? ====
+That depends on the type of system and software configuration.
+A Fronius Smart Meter can be used in these two situations:
+  - when used only for reporting to Solarweb
+  - when used for limiting export, in a system where the Victron system is not configured as an ESS system.
+The Fronius Smart-Meter can not be used for the Fronius built-in export limiting feature when part of a Victron ESS system. Instead, use the Victron ESS Fronius Zero-feed in feature, see chapter 4.3.11, Fronius Zero Feed-in, in the [[ess:design-installation-manual|ESS manual]].
+==== Q5 How can I get the Fronius firmware that improves flickering? ====
+Fronius has a special firmware available, on request, that fixes light flickering issues that occur on certain installations under certain circumstances.
+For Fronius PV inverters produced after 2018-week 16, contain the flicker-fix already straight from production.
+To update earlier and/or already installed PV Inverters, contact Fronius Tech Support for the file. The required file is fro29130.upd. Which works for all snap-inverter models (Primo, Symo and Eco). There is no, and will be no, fix available for Fronius Galvos.
