-Recommended for new systems ​are the SYMO inverters for 3~ systems and PRIMO inverters for 1~ systemsDo 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~ applicationsPlease ​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.

 +===== 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. ​ 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). 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.
