 ===== 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 2.1.3 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? ===
+==== 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.
-=== Q2 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 ===
+==== Q3 The system is locked to 53 Hz and does not resume ====
-Its locked to the upper limit because of a battery over voltage.
+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.
-Or AC must
+A Fronius Smart Meter can be used in these two situations:
-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.
+  - 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.
-Alternatively, power cycle the system with the rocker switch on the front panel on the inverter/charger.
+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]].
-To prevent this from happening again, check your configured float voltage: setting it lower will prevent the overvoltage condition from happening again.
-Notes:
+==== Q5 How can I get the Fronius firmware that improves flickering? ====
-  * all mentioned voltages are for 48V systems. For 24V divide all values by 2, and for 12V divide by four.
+Fronius has a special firmware available, on request, that fixes light flickering issues that occur on certain installations under certain circumstances.
-  * the mentioned 53 Hz is the PV Inverter disconnect frequency as configured in the Assistant, default 53 Hz.
-=== Can I use the Fronius Smart Meter? ===
+For Fronius PV inverters produced after 2018-week 16, contain the flicker-fix already straight from production.
-No, when using a Fronius PV Inverter in a Victron system it is not possible to use the Fronius Smart Meter.
+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.
-Use any of the [[energy-meters:start|Victron supplied Energy Meters]] instead.
