[1] Note that the fourth arm makes it possible to connect a single 3phase inverter as a single or “two phase” inverter (“Two phase” is useful in Single Wire Earth Return systems (SWER) and in US split transformer systems).

[2] Product does not use Electrolytic capacitors at any level – neither Aluminium nor Tantalum.
All capacitors are either polypropylene or ceramic. The Capacitors used on the dc bus have a design life of 30 + years.
