Multiple SM15K units can be connected to form a bigger system. The SM15K units serve as a modular building block in bigger systems, from 2 up to 60 units. The outputs of the units can be connected in parallel and series.

To build your own modular system, output assembly kits are offered. That enable the user to easily and safely configure and reconfigure the outputs of any amount of units, at any time. The output kits can be stacked to connect more units, than offered by individual kits. For example, to connect 20 units in parallel, two assembly kits of ten units and a connecting set for two units can be used to stack.
