Field of use
REFUone inverters are Dual MPPT grid-tied PV inverters which converts the DC power
generated by PV arrays into sine wave single-phase AC power and feeds it to the public
electrical grid, AC circuit breaker (refer to Section 4.4) and DC switch used as disconnect
device, and the disconnect device shall be easily accessible.
PV Grid-tied System
REFUone inverters can only be used with photovoltaic modules that do not require one of the
poles to be grounded. The operating current during normal operation must not exceed the
limits specified in the technical specifications. Only the photovoltaic modules can be connected
to the input of the inverter (do not connect batteries or other sources of power supply).
The choice of optional parts of inverter should be made by a qualified technician who knows
the installation conditions clearly.
