georgelza Posted August 12, 2020 Posted August 12, 2020 As per other thread, I need to update the FW on my Multiplus 2, and the original installer is not coming back, other than finding a new service technician... who has any of these cables ? what software will I need, where will I get the FW.

fredhen Posted August 12, 2020 Posted August 12, 2020 https://professional.victronenergy.com/downloads/firmware/ That's where you can get the firmware and it's got instructions as well. https://www.victronenergy.com/live/updating_firmware:updating_ve.bus_products There's also a guide there. The cable is generally available at most solar shops and @Jaco de Jongh can also help you out there. They're pricey though, so if you know someone who might have one it may be best to just borrow it for the day. Quote

shanghailoz Posted August 26, 2020 Posted August 26, 2020 (edited) Pretty straightforward. Just did a Multi this morning using an MK3 USB cable (which you don't have ). I see you have a GX. If you have a GX connected to it, check if you can update the firmware in the vrm site, may need to turn on bidirectional comms on first though, and need GX firmware > 2.51 Settings / VRM online portal / VRM two-way communication -> on. Then https://vrm.victronenergy.com and click your site, then Device List / Firmware Update. (assuming your GX has internet) Remember, backup settings first!

___ Posted August 26, 2020 Posted August 26, 2020 10 minutes ago, shanghailoz said: I see you have a GX. You can do Multi updates using just the GX, but it is not yet possible via VRM. The tool is included on Venus, and if you root the GX device and you know how to use SSH and you know how to use the vbdup tool, then you can update the inverter remotely. But there is a small risk that you must keep in mind. The vbdup tool requires the inverter to be running when it starts, so it can collect some important information. It then resets the inverter (sends it into bootloader mode) and does the flash. As long as the flash succeeds, no problem. If the flash fails for whatever reason (this is rare, but as I said, I don't know of a single case, but it is a theoretical risk to keep in mind), then the Multi remains in bootloader mode. Now vbdup can no longer be used (cause it cannot collect the information it needs), and now you must use an mk3 and physically connect to the hardware to finish the job. So if you have an mk3 no more than a few hours away form you, or you are willing to take that slight theoretical risk, by all means do the flash remotely. To protect people from themselves, I'm going to rather NOT post instructions here on how to do that. Read the help message the tool spits out. Quote
shanghailoz Posted August 26, 2020 Posted August 26, 2020 @plonkster There's also the GX needs to be powered separately from the system itself to think of, as it will restart the inverter, which will restart anything connected to it! Best to have an MK3 as you've noted. Quote
georgelza Posted August 26, 2020 Author Posted August 26, 2020 ... sorry, never came back, Jaco assisted me (Than you thank you), my unit has been FW updated, the MPPT's I also completed myself, so everything on newest FW now. G shanghailoz 1 Quote

georgelza Posted August 26, 2020 Author Posted August 26, 2020 In this case I did the ssh and executed the commands... thanks for sharing your knowledge with everyone. G Quote
shanghailoz Posted August 26, 2020 Posted August 26, 2020 ...you can live dangerously, as long as you know what you're doing Quote
georgelza Posted August 26, 2020 Author Posted August 26, 2020 Well Jaco knows what he's doing and well I work in IT so know my way around the keyboard and Linux OS's etc. G Jaco De Jongh 1 Quote
