VEICHI 7.5kW THREE PHASE 380V SOLAR VSD (D5 Series)

**Motor Size - 0.37kW up to 5.5kW - 380V 3-Phase Motors

These solar pumping systems utilize a three-phase DC to AC configuration, powered by a solar Variable Speed Drive (VSD) that can be configured for single to three-phase operation. Equipped with an integrated Maximum Power Point Tracker (MPPT), the VSD Drive efficiently transforms DC input from photovoltaic (PV) modules into optimal AC power output at 380V. This converted power is then employed to drive Three Phase AC pumping systems, including both submersible and surface pumps, within the power range of 0.37kW to 15kW. The MPPT function plays a crucial role in enhancing the overall system efficiency by allowing adjustments to motor speed and startup voltages, ensuring optimal performance based on specific speed and pressure requirements.

The Veichi VSD drive has a IP65 packaging and offers Off-Grid and hybrid functionality.

SOLAR PV CONFIGURATION (Depending Pump Size)

(Solar array factor in relation to motor size = 1.6) (Inland) (Coastal Factor = 2)

i.e. 3kW Motor x 1.6 Factor = 4800 Watt of solar panels needed

340W Renewsys Panels String of 16 in series

550W Mono Solar Panels String of 14 up to 15 in series

(Panels not included in this package)

Should you need any assistance please contact one of our sales executives.

MOUNTING STRUCTURE CONFIGURATION (Not included)

(See panel configuration above - applicable to Panel size)

SOLAR ARRAY COMBINER (Not included)

It is imperative to also install a solar string combiner with your system even if only one string is applicable to protect against surge, lightning and overload. (This would also cover any insurance claims should surge damage occur)
