I have bought 3 MP-II 48/3000 because of the low power consumption in ‘search mode’.
I have used them in a ‘summer configuration’ where they are connected as one phase, in parallel. And they have been working all summer (Of course, I haven’t used search mode this summer).
Now I would like to configure it in a ‘winter configuration’, for low power consumption.
Can the 3 MP-II be set to work in 2 (or 3) independent groups that can be turned on and off as needed? Has anyone actually gotten ‘search mode’ to work?
Unfortunately, if you want to turn OFF 2 or 3 of the MP’s then they need to be reconfigured - so this is a semi-permanent change.
Using AES mode does work, and either in search mode or modified sine wave mode. For search to work, the power thresholds need to be carefully set. With 3 units in parallel, you may find the actual threshold is 3 times the value that you program.
If they are programmed as parrallel (even though they are three physically separate units) they are one in programming. If one unit switches off unexpectedly the system will assume there is a problem and shut down the entire system.
You have to set it up as stand alone in programming to be able to use it as a single unit switching separately to the others.
As stand alone if you want control each needs its own GX as well.
The solution is simply, just configure the separate groups by turn off the MP(s) not
in the group.
After configuring the first group (in this case 2 MPs) turn it off and turn on the third MP and configure it as standalone.

The manual list ‘parallel-‘, ‘phase-’ and ‘stand-alone-‘ mode.

remember a distinct name on each MP
