Hello,
Are there more people with a RS450/100 that had internal error 201 after the latest firmware update?
Now I have to sent the unit back to Victron.
Unit is connected to 30kW BYD lithium batery, color control and Quattro 15kW.
asked
RS450/100 internal error 201 immediately after firmware update V1.05
I just made the update and also have the 201 error. The unit seems to work, but it just happened a few minutes ago. Is it possible to downgrade to 1.04 ?
Just fyi I have also a mppt rs 450/100 and had it updated to 1.05 by using the VRM portal and had no issues except of rebooting the whole system (incl multiplus || gx)
Hello, Same symptom in one of our customers.
We are waiting for more informations from Victron.

Thanks for reporting all, I don't have any further information - but am posting to let you know that I have seen these and will pass along the reports. If anyone else is experiencing the same, please also post below.
Re RS450/100 Error 201 updated to latest version 1.15 still doing it, ? Serial # HQ2114FDQCH
Internal resistance reading from 4 to 15MOhms.
Any more ideas beside sending back for replacement? replace the so called failing resistor on site?
It seems to do it at sunset when sun has gone down very odd to happen as the voltage is low on the PV then?

Dear all,
An update: today we released MPPT RS firmware version v1.08, which solves the vast majority of MPPT RS, and Inverter RS, Error 201 issues.
All that is needed to fix it is that firmware update. No repairs, nor any resistor replacements any more. I have removed my earlier answer, since that is now totally replaced by this new information.
To install the update, two methods
1. When connected via VRM, use the Remote Firmware update mechanism. Details in the documentation.
2. When not connected via VRM, use VictronConnect - either connected via Bluetooth or using a VE.Direct to USB cable. Note that it is the necessary to first download the right files from https://professional.victronenergy.com.. Explained in more detail in the VictronConnect manual, chapter 9.2, Using a self-supplied firmware file.
Within a few weeks, we'll release a new version of VictronConnect that includes the necessary files, after which it will no longer be necessary to download them yourself.
Though rare it can still happen that Error 201 shows, and that updating to v1.08 does not help - in that case please issue an RMA via the Victron Distributor involved.
Lastly, my apologies for these issues!

ps. to push this answer to the top, I've accepted it myself.
Confirming that we have seen this on an RS 450/100 as well
Good day Victron staff
Just to add to this topic, I have had 2 x RS 450/100 mppts show the same Error code straight after installation. The Voltage on the 1 unit has never been over 350 Voc but still gives this error and reduces power / cuts out once the battery has been fully charged ?!
If these units are sent for repair, what is to say the resistor replacement, as suggested, will not fail again on re-commissioning ?
Thanks
Mike
Hi Mike, sorry to hear that..!
Hi,
which exact type of resitors are needed for an rs450/100 ?
resistor value:
resistor power:
metalfilm ?:
Thanks.

If it’s running the latest firmware, an RMA is now the next step.
Hi Guy
Issue was the faulty resistors, replaced all good now.
