SolarEdge 11.4 kW Inverter SE11400H-US000BEU4

The SolarEdge SE11400H-US is an 11,400W single-phase Home Wave Inverter built on HD-Wave technology, delivering 99% CEC weighted efficiency in a wall-mount enclosure rated for permanent outdoor installation. Engineered exclusively for use with SolarEdge power optimizers, it supports both 240V and 208V grid connections and ships with built-in revenue-grade production and consumption metering on the -BEU4 configuration — making it one of the highest-output single-phase string inverters available for residential and light commercial systems in North America.

Metering built in, no add-ons needed

Most string inverters at this output class require a separate revenue-grade meter to satisfy utility interconnection requirements or qualify for production-based incentives. The SE11400H-US000BEU4 includes ANSI C12.20 Class 0.5 production metering and 1%-accuracy consumption metering directly in the unit. For installers, this eliminates a separate metering device, conduit run, and commissioning step — and gives homeowners an accurate view of both what their system generates and what the household consumes, all through the SolarEdge monitoring platform.

Where it's used

• High-production residential rooftops: Larger homes with roof space for 30 panels where a single high-output inverter is preferred over multiple smaller units
• 208V commercial or multi-unit applications: Light commercial buildings or multi-family installations wired for 208V split-phase — the inverter supports both voltage classes from the same unit
• Outdoor service panel locations: Installations where the inverter must mount on an exterior wall or in an exposed equipment area — the NEMA 4X enclosure handles rain, dust, and hose-directed water
• Utility-interconnection-required metering: Systems in California (Rule 21) or other jurisdictions where revenue-grade production data is mandated at the point of interconnection
• Retrofit or capacity upgrades: Replacing an older SolarEdge or competitor inverter in an optimizer-equipped system, stepping up output without rewiring existing string home runs

Advanced features

• Integrated arc fault protection and rapid shutdown: Compliant with NEC 2014 through 2023, Articles 690.11 and 690.12 — both triggered automatically on AC grid disconnect, with no external shutdown device required
• Fixed-voltage architecture for longer strings: HD-Wave's fixed DC bus voltage allows longer optimizer strings than conventional inverters, reducing combiner complexity on large rooftops
• SetApp commissioning: Configured from a smartphone over the inverter's built-in Wi-Fi access point — no laptop, no IR remote, no panel-mounted display required during startup
• Module-level monitoring: Built-in visibility into individual panel performance via the SolarEdge monitoring portal, enabling precise fault identification without a site visit

System compatibility

The SE11400H-US is designed exclusively for SolarEdge DC-optimized PV systems — it is not compatible with non-optimized string arrays or microinverter installations. It accepts up to three DC string inputs (14–6 AWG in a 1-inch maximum conduit) and supports RS485, Ethernet, and optional Wi-Fi or cellular communications for monitoring. AC output wiring uses 14–4 AWG in a 1-inch maximum conduit. The -BEU4 SKU includes the consumption meter interface; current transformers for consumption monitoring are ordered separately (SEACT0750-200NA-20 or SEACT0750-400NA-20). The inverter does not include battery storage or backup capability — for those functions, the SolarEdge Energy Hub inverter series should be specified instead.

Why choose the SolarEdge SE11400H-US?

The SE11400H-US is the right choice when a system demands the highest single-phase output SolarEdge offers in the Home Wave line — 11,400W at 99% CEC efficiency — without the added cost of backup or storage hardware that won't be used. The NEMA 4X outdoor rating removes siting restrictions that limit competing units to protected locations, and the built-in revenue-grade metering on the -BEU4 configuration simplifies utility interconnection in metering-required jurisdictions. For installers working on larger residential jobs in California or other Rule 21 markets, this inverter reduces the hardware count, shortens commissioning time, and delivers the compliance documentation utilities require out of the box.
