ATV320U40N4C412 Variable Frequency Drive Altivar 320 Solar 4kW 3ph/380V

ATV320U40N4C412: Schneider Electric Altivar 320 Solar variable frequency drive rated at 4 kW (3-phase 380 V input, 3-phase 380 V output). We use it for a borehole or centrifugal pump supplied from a PV array when the project needs Altivar diagnostics and a predictable automation path.

• Parameters: 9.5 A output current, IP20, 150% overload, maximum frequency 600 Hz.
• What matters: The solar logic is useful specifically for pumps: check the PV string, dry-run protection, and backup supply concept.
• Check before use: For a solar pump, select by more than kW: motor current, pump head, PV voltage, and protection sensors matter.

Schneider Electric Altivar 320 Solar: where this series fits

Altivar 320 Solar is a solar ATV320 variant for pumps that can be supplied from a PV array or the grid. Our catalog currently has 24 active items in this series: 0.4-15 kW, supply variants 1-phase 220 V, 3-phase 220 V, 3-phase 380 V, IP20 enclosures, EMC filter: no. Schneider Electric is not the cheapest route. The usual reason is simpler: Altivar diagnostics, SoMove, documentation, and a predictable cabinet startup.

Typical jobs for Altivar 320 Solar

• Common mechanisms: borehole and centrifugal pumps, irrigation, and farm water-supply systems.
• Selection: first check motor current, load duty, supply voltage, IP rating, and motor cable length.
• Commissioning: with Altivar, define the command source, speed reference, network protocol, and braking need before wiring.

When Altivar 320 Solar is not the right drive

We do not recommend Altivar 320 Solar for a normal conveyor or machine where solar-pump logic adds no value. In those jobs, another Schneider Electric series may be more logical, or INVT / Veichi may be enough when the project does not specifically require Altivar.

Our field note

Schneider Electric is usually chosen for sites with BMS, SCADA, or an older Altivar already in the cabinet. Predictability matters there. Before ordering we ask for a motor nameplate photo and a short mechanism description. That filters out 220/380 V, IP, and braking mistakes early.
