Hi guys, first off thank you very much for the update this means i can parallel two of these now and that is very useful.
Do you have a list of improvements please as i have noticed a few small differences and would like to see what's been done as i don't want to waist peoples time by posting questions that can be answer by a release note...(cant seem to find one - sorry)
Cheers.
Hi @nesswill
Official release notes are available in Victron Professional.
The updated manual and spec sheet will be published shortly.
A short list of changes in RS v1.12
Changes applying to Inverter RS only:
- Add support for AC output parallel and 3-phase operation.
Changes applying to Inverter RS and Multi RS only:
- Fix false-positive over-charge protection (error #29).
- Fix false-positive PV riso protection (errors #41 and #42).
- Remember the operating mode (on/off/inverter only) during a firmware update. Instead of always switching On after a firmware update.
- Fix PV panel power/current readout in case the MPPT converter is off, there can still be current present if the panel voltage is too high.
Changes applying to Multi RS only:
- Add pass-through mode, this closes the AC input relay while the inverter/charger remains off, the MPPT charger remains active. Settable in VictronConnect.
- Add 'External control' support, this allows for self implementation of a control loop by controlling the AC power set-point dynamically.
- Improve inverter PLL to prevent frequency jumps when the AC input is connected or disconnected, this could trigger a PV inverter disconnect.
- Ignore conditional AC disconnect in sustain mode and inverter shutdown due to allow-to-discharge signal.
Changes applying to Multi RS dual-MPPT (PMR482602020) only:
- Fix relay test sequence.
- Remove PE-Neutral monitoring.
Good day Stewart,
please note that on Inverter RS Smart Solar, with latest firmware update is not possible to change the operating mode from "on" to "Inverter only", from both app and VRM.
In addition differently from MPII, RS Smart Solar never had in VRM the respective flag status for Inverter and Solar Charger but only a single flag by the inverter that is serving both functions in confusing way. Would be nice to have it corrected !
Thank you for your attention !
Hi @nesswill,
Here is a late stage draft of the new chapter on the programming of parallel Inverter RS units.
It will be published in the normal documentation shortly along with the physical installation details, but as there are now some specific private messages from users that are asking for it now, I am happy to share it, and even would appreciate any feedback you have.
There is still more to come and what you see here is not yet complete;
Oh my word, it must be Christmas again :) this is great news, particularly the parallel operation on the inverter RS.
Is the parallel operation coming to the Multi RS as well (which is what I'm more interested in)?
A conditional yes.
It is simpler for the engineers to sync just the inverter than both the inverter and charger (and ac input relays).
They are working on 3 phase and parallel support for Multi RS next.
There are other challenges and there might be other limitations.
The intention is there, but until it is done, I cannot say 100% for sure.
Edit - As an update to this initial intention we now already see one limitation - feed-in for three phase systems is only going to work with the new two-tracker models. The older single-tracker Multi RS variant, when configured for three-phase, will not get the feed-in feature.
Other limitations may also arise as we develop and test the feature, and at this time nothing can be assumed.
What about the "Inverter RS 48/6000 230V Smart Solar"? Is parallel and 3 phase also supported? Can solar and non-solar models be mixed?
Hi @espindola,
Inverter RS Solar also supports parallel and 3 phase.
Yes, you can mix solar and non-solar Inverter RS models in parallel and 3 phase installations.
However mixing Inverter RS with Multi RS is not currently supported.
Well, it's my birthday today, albeit a year later. I now have two dual tracker Multi RS units and an older single tracker Multi RS. I can almost sense someone's finger on the release button for firmware at your end but I'm still patiently waiting (I do appreciate the parallel isn't likely yet though)...

Hi Guy.
I will be installing the second inverter in the next few days so was wondering please if there is a full set of updated instructions ready?
Thanks.
Hi @nesswill,
The English language version of the documentation that includes the parallel programming for the Inverter RS Solar is here:
11676-Inverter_RS_Smart_Solar-pdf-en.pdf
It is now being is now being translated into other languages.
There is only a brief window of time where that link is the most up to date manual, maybe until a week from today.
For anyone else that might be seeing this in the future - please get the latest version of the manual from here - https://www.victronenergy.com/inverters/inverter-rs-smart-solar#manuals
Thanks Guy doing it tomorrow so I'll let you know how it goes
Cheers.
Well I noticed that v1.13 of the firmware was available for the Multi RS Solar today which now seems to have support for parallel and three phase! Huge thank you for that one Victron (missed my birthday by only 3 days, which is close enough :) ).
This obviously raises lots of questions. I've read the preliminary documentation for the Inverter RS which only has a mains output and doesn't have mains inputs to deal with so I'm guessing their are rules I need to apply regarding that. Also, does this release add Grid feed in which were hinted at coming in future releases? (Nothing obvious in the settings)
I guess what I'm looking for is the documetation to accompany the update if anything is available yet?
Is this worth opening up as a separate question?
The 1.13 firmware release for Multi RS only adds support for 3 phase configurations, and not parallel (either single phase or 3 phase).
The options in VictronConnect will get an update in the next version of VictronConnect to remove the visibility of the parallel programming options - consider that a bug and thanks for reporting it.
More documentation for 3 phase support of the Multi RS is still underway.
Grid feed-in is not yet ready either, specifically the grid code compliance that would permit grid feed-in is not yet ready.

Hi Guy.
All up and running both inverters sharing the load.
I just want to confirm i have this correct, with Prevent CAN network islanding disabled if one inverter fails, turned off or has a firmware update the other inverter will keep the AC on so no loss of mains power. (i have not turned off one inverter with Prevent CAN network islanding disabled to see what happens yet bt will when convenient)
If i turn on Prevent CAN network islanding and turn off one inverter the other inverter powers off too (stays on but turns the load off so no AC power) i take it this is correct?
Sorry if this is a stupid question i just want to make sure i am understanding this.
Thanks.
hello,
below it says that the Multi RS supports meter and therefore need a beta firmware.
I have installed 1.13, where can I find the beta to test it?
"Meter support" sounds like Grid feedin is coming :)
There isn't a public beta for the RS just yet, I'll find out what the plan is.
Once the RS beta with Victron Energy Meter support is ready I will post a link to it in the modifications space.
