 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.
-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
-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.

-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.

+For the UL inverters, some more Microgrid Setups are available (e.g. for connection with Neutral conductor or without). Also the UL inverters can be used in 60Hz as well as in 50Hz applications. More information can be found in the user manuals.
 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:

-===== Frequently asked questions =====
+===== Zero Feed-in =====
-=== Why doesn't the frequency settings in the Multi and the Fronius need to be the same? ===
+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).
-=== The system is locked to 53Hz and does not drop down ===
+==== Q3 The system is locked to 53 Hz and does not resume ====
-Its locked to the upper limit because of a battery overvoltage.
+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? ====
-The frequency will reset itself once the system switches back to bulk. For this to happen, the battery voltage needs to drop 0.8V below the configured float voltage. Unless float is configured to 54.8 volts or higher, then the battery voltage needs to drop below 54 volts for the system to switch back to bulk.
+That depends on the type of system and software configuration.
-Above voltages are for a lithium battery. When configured for other battery types, the voltage needs to drop 5.2V below the configured float voltage. Unless that is configure to 56,8V or higher, then the battery voltage needs to drop below 51.6V for the system to switch back to bulk.
+A Fronius Smart Meter can be used in these two situations:
-Alternatively, power cycle the system with the rocker switch on the front panel on the inverter/charger.
+  - 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.
-To prevent this from happening again, check your configured float voltage: setting it lower will prevent the overvoltage condition from happening again.
+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]].
-Note that all voltages are for 48V systems. For 24V divide all values by 2, and for 12V divide by four.
+==== 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.
