In VEBus firmware numbers.txt, is there any reason the 500VA is called a "Multi" but the 800VA and up are called "MultiPlus"?
2660 Multi 12/500/20-16 2661 MultiPlus 12/800/35-16 2662 MultiPlus 12/1200/50-16 2663 MultiPlus 12/1600/70-16 2665 Multi 24/500/10-16 2666 MultiPlus 24/800/16-16 2667 MultiPlus 24/1200/25-16 2668 MultiPlus 24/1600/40-16 2670 Multi 48/500/6-16 2671 MultiPlus 48/800/8-16 2672 MultiPlus 48/1200/13-16 2673 MultiPlus 48/1600/20-16
Historically;
'Multi' only has a single AC input, and a single AC output, and did not have PowerAssist.
'MultiPlus' has a single AC input, and two AC outputs.
'Quattro' has two AC inputs, and two AC outputs.
That said, it's a bit tedious to always say MultiPlus, so it is often informally shortened to Multi.
And MultiPlus is now the recognised brand, so the new models now use MultiPlus, even those smaller ones with a single AC output, and without power assist.
Should always check the Datasheet for the specific features of each model.
Edited.
But the 800VA only has one AC Output (I think that applies right up to the 1600VA in the plastic series).
