I designed and built this small 1.5 kW PV system for work.
The PV panels are wired in series to feed the 360V DC link of a 230VAC 2HP Fuji variable speed drive.
The VFD is configured to control a stand alone off grid solar powered pump with max power point tracking.
To avoid pumping water in the lab, the VFD output is connected to 3 centrifugal blower motors and a resistor bank for playing with it in V/f mode.
Its meant to be somewhat portable, but it hasn't moved since I put the PV panels there last summer, except when the grass gets cut.
