Sigenergy Sigen PV 50M1

• Manufacturer Sigenergy

The Sigenergy Sigen PV 50M1 is a 50 kW three-phase string inverter engineered for commercial rooftops, ground mounts and small utility clusters that demand high power density, rapid installation and best-in-class safety. With four independent MPPT trackers—each rated at 20 A and accepting a full 1 100 V DC—the inverter comfortably connects up to 100 kWp of modules (160 % oversizing) and harvests energy across complex orientations or mixed module batches.

Built around high-speed silicon carbide switching, the Sigenergy Sigen PV 50M1 inverter achieves 98.6 % peak efficiency and 98.3 % European efficiency, reducing thermal losses and boosting project IRR. Smart-air cooling keeps the compact 918 × 640 × 340 mm chassis below 60 °C even at full load, while internal consumption falls to < 3.5 W at night to minimise parasitic draw.

Installer-focused advantages

Lightweight 75 kg frame – two technicians can hang the unit without lifting gear, slashing labour costs.

Plugless parallel networking – multiple inverters sync over RS-485 or Ethernet; no external data logger required.

Industry-leading AFCI 2.0 – arc-fault detection reacts in milliseconds, cutting fire risk and meeting insurance mandates.

Instant reverse-polarity alert – LED and cloud alarms warn if strings are mis-wired before damage occurs.

IP66 all-aluminium housing – withstands driving rain, dust storms and ammonia or salt-spray environments; ideal for coastal rooftops and livestock sheds.

Wide environmental window – operates from –30 °C to +60 °C and up to 5 000 m altitude (derates above 4 000 m).

Commercial value for EPCs & installers

Lower BOS costs – 50 kW per 0.6 m² footprint reduces combiner boxes, cable runs and mounting steel.

Faster PTO – Sigenergy’s cloud portal provides remote commissioning, IV-curve tracing and live PR monitoring, reducing site revisits.

Future-proof compliance – CE-marked, IEC 62109-1/-2 and EN 61000-6 EMC certified; ready for G99 and CEI 0-21 paperwork.

Smart-grid ready – 0.8 leading ~ 0.8 lagging power-factor control, reactive support and zero-export modes satisfy DNO grid-service schemes.

Choose the Sigenergy Sigen PV 50M1 to unlock high-efficiency generation, uncompromising safety and cloud-first O&M in a single, installer-friendly package that keeps commercial PV projects on schedule and under budget.
