Cerbo Gx displays correct kW output from SolarEdge Se6000. But only a fraction of this is reported in the VRM data. So when I have actually generated, say 6kWh during the day VRM is reporting 0.2kWh.
All firmware upto current date

Multiplus 2 48/5000/70-48. V502
I have a 3 Phase Victron ESS system with a Solaredge 4kw inverter on PH1 on AC1 input. Now we are getting more sun I have noticed that the grid meter is showing that I am exporting unto 1.2kw to the grid at times and the energy isn't being used to charge the battery on that phase. Have I missed something in the setup electrical of software? I have check my settings for exporting to the grid in cerbo. Screenshot 2023-03-10 at 13.26.59.png
I have a Solaredge SE4000 connected to Phase 1 AC input and 95% of the time the Cerbo see the unit and calculates everything smoothly. The solar edge drops connection occasional once or twice every five mins. (It was the same on another modbus slave so its a solar edge issue) problem is I think it throws the ESS monitoring out for a few seconds when it connects and goes, would it be more sensible to put a grid meter on the solar edge and use that instead?
I have a Solar edge device on L1 of an ESS system, everything seems to work apart sometimes I have wild swings in grid input/output. I have not added a power meter to the solar edge or link the Victron to the solar edge, main as didn't fully understand the settings of relay and what they actually did, can someone explain what and how to do this and why pls.
I have a SolarEdge inverter currently on the AC OUT. However it isn't responding to frequency changes in APS mode so I am going to have to move it to AC IN to avoid damaging equipment. All the loads are on the AC OUT so the only things connected to AC IN would be the grid and the Solar Edge.
The ESS manual states that all inverters on the AC IN need to have an energy meter fitted as well. Is this required in the case of the SolarEdge as it is already communicating via modbus TCP?
Good day .
Is there a way to determine why the inverter is Frequency Shifting ?
Is it possible to find out were the command comes from ?
I am running 3 x 48/15000 Qauttro , 56KWh Solar MD batteries and Solar Edge 27.5 Grid tie inverter.
The Qauttro's seems to shift the frequency and the solar edge starts throttling. Is there any way to determine what will make the Qauttro's start frequency shift ?
currently I am setting up an off grid PV-system and try to integrate AC coupling with Solaredge SE6000H and Quattro 48/8000. (Battery is BYD premium LVL)
I followed the instructions in Victron documentation: Integrating with Solaredge
The only difference is: There is no public grid available and zero feedback is not required. Therefore no Solaredge Energy Meter is installed.
My question: is the use of the Energy Meter mandatory for the correct working of frequency based power reduction by the SE inverter?
Which country settings (on the SE inverter) did you use in your test environment?
I ask, because my test run failed.
First I used "Spain" as country setting and noticed, that in the SetApp Power Control-->Active Power the P(f) menu was missing. I reconfigured country settings this time to Czech Republic 16A and was curious to see that P(f) was back again.
(Although I doubt, that this setting is at all relevant for my setup as I will not be working in that specific country mode, but in APS (Alternative Power Source) mode.
But to follow the documentation I set P(f) in both menus: In Power Control-->Active Power-->P(f) and Power Control → Alternative Power Source → P(f) and ranging P0 100%@ 50.2Hz and P1 0%@ 51.2Hz.
On Victron side I use the assistant PV-Inverter and with the same tresholds and disconect @ 51.5 Hz.
However the test run failed. (And yes, SE status said I was in APS mode). No power reduction on SE-side happened. Victron modulated the frequency up to 51.5Hz and luckily and thanks to the relay assistant and SE on AC-Out 2 it got thrown off when BatV got too high.
Thanks for any inspiration!!
I'm trying to work out where to place my SolarEdge inverter. All my loads are on AC Out 1&2 on a Quattro 10000. A heat pump and car charger are on the AC Out 2 (dropped loads). My three options are
So my question is - If connected to AC OUT 2 worst case in the summer and the inverter is at maximum output of 5kW and the grid goes down what would happen at that point? Would the inverter shut down fast enough to avoid damaging the rather expensive heat pump and car charger? They might not be actually pulling any load so that seems like a lot of power to suddenly store in capacitors? Does a SolarEdge or any inverter for that matter shut down quickly enough in that scenario. I know I have the APS issue if I switch over to the critical loads but I can choose if I want to turn the inverter on/off before switching. Ie, in the winter it isn't a problem. I only have a few days to make this decision as the installation is being completed on Tuesday.
edit: made the question more specific to ac out 2
I tested my SolarEdge SE5000 HDwave response to the frequency rise. The battery was 100% and it still continued putting out maximum power requiring manual intervention with myself. Both technical notes from Victron and SolarEdge were followed. The Solar Edge technical team confirmed my settings were correct when I contacted them. They updated all firmware and it still doesn't work. So if you have a SolarEdge connected on the AC out you might find it doesn't work as advertised when you really need it to. For safe testing you can follow my answer to this question https://community.victronenergy.com/questions/184775/can-i-control-the-frequency-output-of-the-quattro.html so you are not running close to 100% SOC.
I would strongly recommend testing the response in island mode with a less than full battery to avoid damaging lots of equipment. Right now I am considering playing safe and moving it back to the input side of the Quattro.
Hi, I've set up my new Quattro as per the instructions in this document and in normal use it's all working fine. However there is a line in section 3 that states
"Note: In addition to the settings above it is important to contact SolarEdge Support to change a parameter in the backend to allow the frequency shifting with APS mode."
Having contacted SolarEdge they seem to think everything is set up fine on the machine and there is nothing to do from their backend. Does anyone know what that might be referring to please? I will often be running with a full battery and a lot of export so don't want to damage anything if there is a power cut in the summer.
There is a system:
3 х MultiPlus-II 48/5000/70-48, PV Inverter Solaredge SE7K-RW0TEBNN4 PositionAC output
All settings have been made as per the document: https://www.victronenergy.com/live/venus-os:gx_solaredge
Cerbo GX has all settings and restrictions set
As a result, there is generation into the grid
Question: How do stop generation into the grid?
Thanks to everybody willing to help!
i am planning an ESS System in Europe/Austria. With 3xMultiplus II 5000 and Solaredge SE16K and Victron MPPT RS450/200. in general it should look like this:
I read through the Victron/Solaredge instructions, but still have some open questions:
1. Victron 1:1 Rule:
Sadly, there is no SE15K model available anymore. So the SE16K would be basically too big for installing it on AC-Out. But i think it should be somehow possible, to limit its output generally to 15kW. Then i think 1:1 rule is acceptable solved
2. Dry Contact:
If i understand it correctly, it would be sufficient to wire the first Multi K1 relay to the SE16K. If grid is lost, this relay will tell the SE16K to change to APS mode, correct?!
3. Victron grid meter and/or Solaredge smart meter needed?
I don´t understand, if a victron EM24 or some solaredge smart meter would be required or not?!
I do not have any loads or PV-inverters on AC-In. So basically the multis would not need any grid meter, correct?!
But does the SE16K need a Solar Edge smart meter? And if so, why? And which model?
4. zero feed in:
It might be possible, that the authority forces me to enable zero feed in, by an external NC contact. Would this be supported by Victron Multis?
input closed -> feed in allowed
input open -> zero feed in required
Will this work with EM24 or Solar Edge Smart meter?
thanks to everybody willing to help!
I have a system with 1 Solarege 3,5kW and Multiplus 2 with battery. All works well together. I read the solaredge PV data into the Victron VRM (Solaredge Register 811) with TCP Modbus like explained by Victron.
But now I want to install a second Solaredge Inverter (3 Phase). How can I get the second PV production value into my Victron sytem, either the sum of both, or each one?
Victron installation manual only offers to read out the device ID 126. Is it possible to add addtional pv production systems? I think this option will be interesting for many people.
I have an ESS with Fronius PV-Inverters coupled on AC-in and AC-Out.
As Victron supports Fronius, those inverters are shown with a fronius symbol at remote console and VRM.
I think about adding a Solaredge PV-Inverter at the AC-in side.
Is this supported? and how will it then be shown on the Victron Displays?
Will an additional PV-Inverter box show up for the Solaredge?
Or will the Fronius Symbol just disapear, and the values for Fronius and SE will be shown combined in the existing PV-Inverter box?!
Or will it confuse the Victron Display and create an error?
i have installed an ESS with 1x SE7K on AC-in, 1x SE15K on AC-Out1 and 1xMPPT RS450/100, with 3x Multiplus II 48/5000.
Some of the instructions of the Victron/Solaredge AC-Coupling manual are not very clear...
1. How to enable APS via Multi Relay Output?
1a. which is the correct relay?
I want to use the blue "AUX RELAY" for that:
- "AUX-RELAY" at the Multi
- "ALARM CONTACT" in the Multi Manual
but none of these names is available in the VEConfig "programmable relay" Assistent:
I assume, the first option "Use primary programmable relay" is this blue "AUX Relay"
1b. how to configure it?
first -> "Set relay on" to have it configured as "normally open"
then -> check "AC Input", correct?
-> then choose no extra options to trigger the relay?!
-> and then.... set it to "when AC1 is not available for 0 seconds"??
So the relay should immediately trigger, once Grid fails, isn´t it?
Or does it not work correctly with 0 sec. and i need to choose 1sec or higher number?
2. ESS assistent setup of frequency shift?
the Victron/Solaredge instructions call out, to use these values.
Is this really correct??
Those numbers seems to be a very tight range?
I am used to Fronius AC-Coupled System, which allow up to 53Hz before disconnecting the PV-inverter.
Does the 51,5Hz really work sufficient or good with Solaregde?
It seems to be very small room for frequency regulation?!
But maybe i am wrong with that, and Solaredge works super fine with these numbers?! I don´t know. Does anyone have experiance on this?
