question

Hi @DeVerm,

People are still buying both models (which is why they are both still for sale), there is more to it than just the price.

I will give some of the reasons though, the MultiPlus-II;

• Uses a new external casing now made from steel, not aluminium.
• Uses a new and more modern circuit deposition technique, smaller chips with fewer integrated circuit components required. Less silicon overall.
• Uses a single larger toroidal transformer, rather than two smaller ones (peak surge power rating is decreased slightly, but efficiency is increased)
• Is physically smaller (due the reasons above) increasing units per container (and reducing shipping and warehousing costs).

None of those are necessarily inferior, but they all reduce the costs.

Both products are now mature, and built on the same power bridge, firmware, and power electronics platform. There are no unresolved software bugs that I am aware of.

There are some markets where the additional features of MultiPlus-II make it the necessary choice, such as the double acting AC input anti-islanding relays.

Others where the MultiPlus may still have advantages.

Victron will still happily sell either, and back them both with the same 5 year warranty (upgradable to 10! :)
