For solar installers wiring two MPPT inputs into a residential or commercial PV array, the Eaton DC Stringbox consolidates two strings into two outputs with integrated Type 2 surge protection and a 2-pole DC disconnector. The IP65 polycarbonate enclosure withstands UV and weather, while MC4 connectors speed up field connections.

Key specifications

  • Inputs: 2 strings
  • Outputs: 2
  • Max. system voltage: 1000 V DC
  • Max. current per string: 15 A
  • SPD type: Type 2 (In 20 kA, Imax 40 kA)
  • Connectors: MC4
  • Enclosure: IP65, UV-resistant polycarbonate
  • Integrated DC disconnector: 2-pole, 32 A
  • Operating temperature: -25°C to +50°C

Why choose it

Combining string fusing, surge protection and a load-break disconnector in one enclosure reduces wiring time and potential fault points. The IP65 rating and UV-stable housing suit outdoor installation, and the 1000 V DC rating matches modern string inverter inputs.

Ideal use cases

  • Residential PV systems with two strings per MPPT
  • Small commercial rooftops up to 1000 V DC
  • Retrofits where a separate DC disconnect is required

Good to know

The box supports two MPPT inputs and is designed for wall mounting. MC4 connectors are pre-installed for quick connection to standard PV cables.
