SolarEdge SE11400H-US000BEU4 11.4 kW Single Phase Inverter

The SolarEdge SE11400H-US000BEU4 is an 11,400W SolarEdge HD wave inverter built for residential solar systems at the top of the single-phase output range, combining 99% CEC weighted efficiency with built-in revenue grade production metering and consumption metering in a single unit. Designed exclusively to work with SolarEdge power optimizers, this Home Wave Inverter operates at a fixed 380V nominal DC input voltage — enabling longer strings and simpler DC wiring than traditional MPPT string inverters — and ships ready for commissioning via the SolarEdge SetApp mobile application.

Note: The "BEU4" suffix in this part number indicates the inverter includes both revenue grade production metering (0.5% accuracy, ANSI C12.20) and consumption metering (1% accuracy). Consumption metering requires separately ordered current transformers (SEACT0750-200NA-20 or SEACT0750-400NA-20). If metering is not required, a base model without this suffix is available.

Note: This inverter requires SolarEdge power optimizers on every module. It is not compatible with standard string configurations or third-party optimizers, and will not operate without optimizers installed.

Fixed voltage design and HD-Wave technology

Unlike conventional MPPT string inverters that track voltage across a wide DC input window, the SE11400H-US operates at a fixed 380V nominal DC bus maintained by the SolarEdge power optimizer network. This fixed voltage architecture allows longer strings — up to 480V maximum — reducing the number of strings and DC home runs required on large residential rooftops. HD-Wave technology performs the DC-to-AC conversion using a novel switching algorithm that substantially reduces the magnetic components inside the inverter, which is how SolarEdge achieves a 99% CEC weighted efficiency rating in a compact, lightweight enclosure that can be mounted indoors or outdoors.

Where it fits

• Large residential rooftop systems: At 11,400W, this is the highest-output single-phase Home Wave Inverter in the SolarEdge lineup — suited to homes with high energy consumption, EV charging loads, or large available roof area.
• New SolarEdge optimizer builds: The natural central inverter for any installer specifying SolarEdge power optimizers — this unit and the optimizer network are designed as an integrated system.
• Systems requiring revenue-grade metering: The BEU4 suffix delivers ANSI C12.20-certified production metering and optional consumption monitoring in one unit, eliminating the need for a separate utility-grade meter for NEM or performance-based incentive programs.
• Partial-shade or complex layouts: Module-level optimization via SolarEdge power optimizers means shading, soiling, or mismatch on individual panels does not reduce output from the rest of the string.

SetApp commissioning and monitoring

• Commissioning is handled entirely through the SolarEdge SetApp mobile application via the inverter's built-in Wi-Fi access point — no laptop or separate configuration tool required on the roof.
• Built-in module-level monitoring tracks production data per optimizer through the SolarEdge monitoring platform, giving homeowners and installers per-panel visibility into system performance.
• Communication interfaces include RS485, Ethernet, optional Wi-Fi, optional cellular, and optional SolarEdge Home Network — giving installers flexibility across different site communication scenarios.
• Automatic rapid shutdown triggers on AC grid disconnect, meeting NEC 2014 through NEC 2023 requirements for both AC and DC conductors under articles 690.11 and 690.12.

System compatibility

The SE11400H-US000BEU4 requires SolarEdge power optimizers on every PV module — the fixed DC bus voltage and module-level monitoring are both delivered by the optimizer network, not the inverter alone. DC input accepts 1 to 3 strings via 1-inch maximum conduit with 14–6 AWG conductors; AC output uses 1-inch maximum conduit with 14–4 AWG. The inverter supports both 240V and 208V AC output, making it compatible with standard North American residential split-phase services as well as some light commercial 208V single-phase applications. Consumption metering requires the addition of current transformers (sold separately: SEACT0750-200NA-20 or SEACT0750-400NA-20).

Why choose the SolarEdge SE11400H-US000BEU4?

The SE11400H-US000BEU4 combines the highest single-phase output in the SolarEdge Home Wave lineup with a factory-integrated revenue grade metering package that competing inverters require additional hardware to match. At 99% CEC weighted efficiency, it sets a benchmark that most residential string inverters do not reach, and the fixed-voltage optimizer architecture delivers consistent module-level performance regardless of partial shading or string mismatch. For installers building premium residential systems where production accuracy, high output, and per-panel monitoring are all requirements, A1 SolarStore offers this unit as a complete solution in a single SKU.
