where to download firmware for Multiplus 48v 5000 inverter

currently don't have access to AC PV sourcing / linking assistant I believe it is because my unit is behind on firmware,

previously was DC linking a sepparate 3rd party MPPT controler to the batteries, however have a SMA Sunny boy inverter ready to wire in but can't until i get this firmware


where can i download the updated firmware that supports PV shift power control from?

also all of the labels and stickers I've put details below.

Hi @Alistair Hutten

The last number you posted is the important one. The 2624 is your mainboard identifier, the 158 the firmware it came with.

465 is the latest firmware, so the file you're looking for is 2624465.vff

You'll find it here: https://professional.victronenergy.com/

You'll need to sign in, but that shouldn't be difficult. Look in Firmware > VE.Bus section.

Good luck.
