Sure, I can break that down for you.
VE.Bus products have a compatibility matrix that matches certain functionalities with the appropriate firmware versions, based on the type of microprocessor in use.
If you’re working with an old microprocessor, labeled as 19/20, here’s what you need to know:
-
Firmware 150-199 supports the Virtual switch functionality.
-
Firmware 200-299 does not support the Virtual switch but enables Assistants.
-
Neither firmware range supports “Averaged watts”, “kWh counters” or “Wired AC Current Sensor”.
For the new microprocessors, labeled as 26/27, the compatibility is broader:
-
Virtual switch is supported in the 150-199 and 400-499 ranges only.
-
Assistants are supported across all firmware versions from 200-499.
-
“Averaged watts” and “kWh counters” are available from firmware 205 onwards and are available up to 499.
-
Wired AC Current Sensor is supported from firmware 200 and beyond.
Regarding specific Hub systems:
-
Hub-1 is supported by firmware 300-499.
-
Hub-2 v2 is only compatible with firmware 200-299.
-
Hub-2 v3 requires firmware 300-499.
-
Hub-4 requires firmware 400-499.
It’s important to note that firmware versions in the 3xx range are not recommended for new installs; you should use the 4xx or 5xx range instead.
Firmware versions below 150 can always be updated to the latest 1xx version. Features like measuring watts instead of VAs and averaged watts have been introduced in certain firmware versions and are not available for the 1xx firmware series.
Lastly, kWh counters are a feature of firmware versions 154, 205, 300, and 400 but are only functional with the new microprocessors.

Firmware versions 110 to 143: These are designed for old microprocessor systems and come with Virtual Switch functionality. They are the earliest versions and are tailored for systems that don’t require the advanced functionalities provided by Assistants.
Firmware versions 150 to 199: This range supports Virtual Switch functionality and is unique in that it caters to both old and new microprocessor systems. This makes these versions quite versatile, as they can be used across a wide range of products.
Firmware versions 200 to 299: These versions are equipped with Assistant functionality and are compatible with both old and new microprocessors. Assistants allow for more complex configurations and are useful for systems that need a higher level of customization.
Firmware versions 300 to 399: This range is also equipped with Assistant functionality but is exclusively for new microprocessor systems. They offer the same advanced configuration options as the 200-299 range but are optimized for the latest hardware.
Firmware versions 400 to 499: The most advanced range, these firmware versions provide both Virtual Switch and Assistant functionalities and are only for the new microprocessor systems. These versions offer the greatest flexibility and customization options for the most complex and modern systems.
Firmware versions 500+: This latest series of updates introduces a variety of specific improvements and fixes, primarily targeted at new microprocessor systems. Key features include enhanced Solar/Wind priority mechanisms, relay testing improvements to prevent false errors, and specific fixes like addressing fan noise issues in certain MultiPlus-II models and connection issues in Quattro-II systems. While these updates are highly specific and may not introduce broad new functionalities, they are crucial for maintaining system reliability and efficiency in the latest Victron systems.
