PV Voltage Stabiliser
Challenge:
Solution:
Dynamic - PV Voltage Stabiliser reduces and stabilises voltage changes when introducing new PV production in existing grids
Robust - smart transformer construction - no moving parts, no semiconductors in power circuit, no maintenance
Safe - no power failure at customer in case of overload or fault - PV Voltage Stabiliser automatically safely bypassed
Flexible - easy installation of PV Voltage Stabiliser - stand alone, no communication or remote control needed

PV voltage stabiliser
Pilot Project
Challenge: Magtechs pilot customer has many cases where new
solar photovoltaics are being installed in existing low voltage
grids. Often there is as much as 10
times more production of electric
energy than consumption. These
grids were built many years ago,
and dimensioned for purely consumption. Either production must
be limited / reduced, or larger grid
investments are necessary, to
maintain satisfying voltage quality.
Solution: Full PV production is
achieved and more PV installations
are possible with Magtech PV Voltage Stabiliser - without any further
grid investments.
