the INVOLAR
MAC500
achieves precise variable frequency control for
soft-switching during full load range. So that the
MAC500
exhibitslow profile and
high efficiency,additionally the
MAC500
shows high reliability, high power factor and
low total harmonic distortion.
The INVOLAR
MAC500
realize the system expansion
by simple parallel operation(maximum14 PV modules per branch)
