+ | ===== Frequency shifting ===== | ||
+ | |||
+ | To make sure that the Fronius PV inverter works well with Victron inverter/ | ||
+ | * 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: | ||
+ | |||
+ | And the [[ac_coupling: | ||
+ | |||
+ | ===== Fronius / Victron specifics ===== | ||
+ | |||
+ | This is a very easy setup. The Fronius Setup Microgrid has been developed in close cooperation with Victron. During commissioning, | ||
+ | |||
+ | **Compatible ROW inverters** (for " | ||
+ | * Fronius Primo (1~, 3 kW up to 8.2 kW) -> Software // | ||
+ | * Fronius Symo (3~, 3 kW up to 20 kW) -> Software // | ||
+ | * Fronius Eco (3~, 25 kW or 27 kW) -> Software // | ||
+ | * Fronius Agilo (3~, 75 kW up to 100 kW) -> Software // | ||
+ | * 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 Fronius Symo and Fronius Eco inverters are recommended for 3~ applications. The Fronius 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 and two MPP trackers. | ||
+ | |||
+ | **Compatible UL inverters** (for "US type AC grid") are: | ||
+ | * Fronius Primo UL (1~, 3.8 kW up to 15 kW) -> Software // | ||
+ | * Fronius Symo 10-24 480V (3~, 10 kW up to 24 kW) -> Software // | ||
+ | * Fronius Symo 10-15 208-240V (3~, 10 up to 15 kW) -> Software // | ||
+ | |||
+ | 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: | ||
+ | [[http:// | ||
+ | |||
+ | ===== 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 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. | ||
+ | - Ready to start up. | ||
+ | |||
+ | ===== Setting up the Victron Multi or Quattro ===== | ||
+ | |||
+ | - After connecting the MultiPlus or Quattro with the battery, you can now connect a computer through the VE.Bus (in combination with the Victron interface MK2USB) to configure the system with the latest version of the software VE.Configure. | ||
+ | - Go to the tab Assistants: \\ {{: | ||
+ | - Add one of the Assistants that regulate output frequency: | ||
+ | - [[ess: | ||
+ | - PV Inverter support | ||
+ | - Note that it is not necessary to change the default settings in the Assistant. \\ {{: | ||
+ | - Complete the rest of the Assistant and write the new settings to the MultiPlus or Quattro. | ||
+ | \\ | ||
+ | |||
+ | Table for settings for 50Hz and 60Hz frequency | ||
+ | | ** State ** | ** 50Hz ** | ** 60Hz ** |. | | ||
+ | | Start| 51.0 | 60.2|Hz| | ||
+ | | Minimum| 52.7 | 62.7|Hz| | ||
+ | | Disconnect| 53.0 | 63.0|Hz| \\ | ||
+ | |||

+ | |||
+ | ===== Remote system monitoring ===== | ||
+ | |||
+ | The Victron system can be monitored through Victron VRM Portal if a [[https:// | ||
+ | The Fronius PV inverter data can be [[ccgx: | ||
+ | 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:// | ||
+ | |||
+ | ===== 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: | ||
+ | ===== Frequently Asked Questions ===== | ||
+ | |||
+ | ==== Q1 Why doesn' | ||
+ | |||
+ | 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? ==== | ||
+ | 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 [[: | ||
+ | ==== 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: | ||
+ | |||
+ | |||
+ | ==== 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. | ||
