Product Overview

SOLAREDGE SE33.3K-USR48BNU4 3PH Inverter 33300W 277/480VAC /Neutral WYE /AFCI /Safety-Switch /Rapid-Shutdown Enabled /SetApp Commissioning

The SE33.3kUS inverter can connect to 480 VAC 3-P WYE configuration grids. The SolarEdge inverters are designed to work exclusively with SolarEdge power optimizers, and can use either single-module optimizers, or dual-module optimizers. MPPT and voltage management is handled by the power optimizers, allowing for a very high-efficiency, low-cost inverter.

The SE33.3kUS inverters operate with fixed input voltage of 850 VDC. The fixed input voltage from the optimizers allows for longer module string lengths, resulting in less wire line losses and fewer system components. These wall-mountable inverters are lightweight, and have built in module-level monitoring. They include an integrated code-compliant DC disconnect, Ethernet interface, and RS-485 serial port. All SolarEdge inverters are listed to UL 1741 and UL 1699B for the U.S.A. and Canada and are NEMA 3R rated. The inverters are rated for use from -4 °F to 140 °F temperatures. The SE14.4kUS and the SE33.3kUS inverters also come with three fused DC+ and DC- inputs, eliminating the need for a third-party fused combiner box.

The new range of SolarEdge three phase inverters have a smart new commissioning method. Inverter commissioning is done directly through a smartphone using the intuitive SetApp mobile application. Take your inverter commissioning to the next level. NOTE: SetApp Cellular or Zigbee compatible card must be used if applicable.

Main Features:-

  Easy Inverter Commissioning with Inverter SetApp,
  Max Power per String = 6000 watts (208V) or 12,750 watts (480V),
  Integrated arc fault protection (Type 1) for NEC 2011 690.11 compliance,
  Pre-assembled DC disconnect/safety switch for faster installation,
  Small, lightweight and easy to install, by a single person on supplied bracket,
  Outdoor and indoor installation - IP65 / NEMA 3R,
  Fixed string voltage - allows for easier design with uneven string lengths, resulting in optimal inverter efficiency, reliability, and reduced install costs,
  Module level MPPT - prevents energy loss due to module mismatch or partial shading; more quickly reacts to changes in sun irradiance and temperature, minimizing power loss on cloudy days, and increasing overall energy yield,
  Built-in communication gateway with LAN and wireless connectivity options enable easy broadband connection to a remote monitoring server,
  Free monitoring for 25 years,
  Superior efficiency (>97%),
  Optional Rapid Shutdown functionality for NEC 2014 690.12,
  Standard 12 Year Warranty extendable to 20 or 25 years ,
