SolarEdge Home Wave Inverter Three Phase 6kW 8kW 9kW 10kW | SetApp Three-Phase Solar Inverter for UK Grid

The SolarEdge Home Wave Three-Phase Inverter is available in 6 kW, 8 kW, 9 kW, and 10 kW variants, all sharing the same compact, fanless enclosure and designed exclusively to work with SolarEdge Power Optimisers on UK three-phase residential and small-commercial solar installations. Fixed-voltage DC bus technology decouples inverter operation from panel-side voltage fluctuations, enabling longer strings and consistently high efficiency regardless of shading, module count, or temperature swings. Module-level monitoring is built in as standard; commissioning is carried out entirely via the SolarEdge SetApp smartphone application over the inverter’s own Wi-Fi access point – no display, no keypad, no extra tools required. The IP65-rated enclosure suits both exterior wall mounting and indoor plant-room installation. All four ratings share the same 540 × 315 × 191 mm footprint and 16.4 kg weight, so the same bracket, cable routes, and labour methodology apply across the whole range. 98% Peak Efficiency IP65 Indoor & Outdoor 16.4 kg All Four Variants <40 dBA Noise (no external fan) 12–25 yr Warranty Options 🔴 Installation & grid-connection requirements These inverters must be installed by a competent, qualified solar PV engineer and notified to the Distribution Network Operator (DNO) under the appropriate generation connection standard before energisation. The 6 kW variant (2 kW per phase) typically falls under G98 and requires only a DNO notification. The 8 kW, 9 kW, and 10 kW variants may require a G99 application and DNO approval depending on total connected generation and local network conditions – confirm with the DNO before installation. In all cases, the inverter firmware must be updated via SetApp during commissioning as SolarEdge explicitly requires this step for G98/G99 compliance. Do not energise before the applicable notification or approval period has elapsed. 🟠 Power Optimiser requirement & variant selection These are optimiser-based inverters with no built-in MPPT trackers. Solar panels cannot be connected directly – the system requires compatible SolarEdge Power Optimisers on every panel. Choose the output rating to match the system’s designed AC export capacity and DNO connection conditions. The maximum DC input power differs per variant (see spec table) and sets the ceiling for total optimiser-connected module STC power. If pairing with S650A Power Optimisers, verify the inverter was produced after WW42/2020 and that firmware is 4.22.XX or higher before commissioning. 💚 Why fixed-voltage DC bus outperforms conventional string MPPT A conventional string inverter runs MPPT across the entire string – one shaded or mismatched panel drags every other panel in that string below its peak. The Home Wave’s fixed-voltage DC bus receives a stable, pre-conditioned voltage from the Power Optimiser array, so the inverter always operates at its designed efficiency point regardless of what is happening at individual panel level. This enables longer strings, simpler wiring runs, and the ability to combine panels at different orientations or tilts on the same string – arrangements that would cause serious mismatch loss in a conventional string topology. Key Features No External Fan – Silent Operation Thermal management is handled entirely by the enclosure’s heat-sink geometry, with no external fan. Noise stays below 40 dBA in continuous operation – quieter than a library – making the Home Wave suitable for mounting adjacent to a bedroom or living space. Fewer moving parts also means one fewer component to age or fail over a multi-decade service life. SetApp Smartphone Commissioning There is no physical display or keypad. The inverter creates a local Wi-Fi access point that the installer connects to using the SolarEdge SetApp mobile application, enabling rapid commissioning, firmware updates, fault diagnostics, and configuration changes from a phone – without specialist hardware or a laptop on site. Built-In Module-Level Monitoring When paired with Power Optimisers, the Home Wave relays real-time per-panel performance data to the SolarEdge monitoring platform. The owner can view live output from every module on their phone; the installer can pinpoint a faulty or soiled panel remotely rather than discovering slow yield losses months later on a quarterly report. Smart Energy Management Supports export limitation and SolarEdge Home Energy Management device control natively. Compatible with SolarEdge’s Home Network for integration with EV chargers, battery storage, and hot-water diverters – enabling the system to self-consume solar intelligently rather than simply exporting surplus to the grid at low rates. Integrated Arc Fault Protection Includes user-configurable arc fault circuit detection inside the inverter, monitoring the DC side for the early electrical signature of a developing arc fault. This provides a fire-safety layer beyond the connector-level Sense Connect protection built into S-Series Power Optimisers – a meaningful addition on any installation where cable routing or connection quality cannot be visually inspected after handover. Uniform Footprint Across All Four Ratings The 6 kW, 8 kW, 9 kW, and 10 kW units share the same 540 × 315 × 191 mm enclosure and 16.4 kg weight. A system initially sized at 6 kW can be upgraded to an 8 kW or 10 kW unit later using the same bracket position, cable glands, and conduit – eliminating the civil cost of a future inverter swap.

Frequently Asked Questions Can panels be connected directly without Power Optimisers? No. The Home Wave Three-Phase is an optimiser-based inverter – it relies on SolarEdge Power Optimisers to condition DC voltage before it reaches the inverter. There are no built-in MPPT trackers for direct-panel input. Connecting panels without optimisers is not supported and would void the warranty. Which output rating should I choose? Select the variant to match the intended AC export capacity of the system, considering DNO export limits and grid connection constraints. As a guide: the 6 kW is suited to smaller domestic three-phase installations exporting around 2 kW per phase; the 8 kW gives useful headroom for a slightly larger array while remaining compact; the 9 kW and 10 kW suit larger roof areas or where maximum three-phase balanced loading is required. The maximum DC input power also scales with the rating (9 kW / 12 kW / 13.5 kW / 15 kW respectively), so array oversizing headroom differs between variants. Does the 8 kW variant need G98 or G99 notification? The 8 kW inverter at 400/230 V three-phase exports approximately 2.67 kW per phase, which is below the 3.68 kVA per-phase G98 threshold. In many cases it will fall under G98 notification rather than requiring a full G99 application – but this depends on total connected generation capacity at the connection point, including any existing generation already notified. Always confirm the applicable standard with the DNO before installation, as site-specific factors can change the notification route. Is it compatible with the SolarEdge S650A Power Optimiser? Yes – with conditions. Pairing with the S650A requires the inverter to run firmware 4.22.XX or higher AND be produced after week 42 of 2020 (WW42/2020 – check the serial number label: S/N format SJWWYY-xxx). Always update firmware via SetApp during commissioning as SolarEdge mandates this step. Note that S650A optimisers cannot be mixed with other optimiser types on the same inverter. How is the inverter commissioned with no display? The Home Wave has no physical display or keypad. All commissioning is performed via the SolarEdge SetApp mobile application, which connects to the inverter over a built-in local Wi-Fi access point. SetApp handles firmware updates, configuration, panel mapping, and fault diagnostics. No internet connection is needed at the site for the commissioning process itself; internet is used only for ongoing cloud monitoring once the system is live. Can it be wall-mounted outside, and how noisy is it? Yes. The IP65 rating means the Home Wave can be mounted on an exterior wall exposed to rain and dust, or equally inside a garage, utility room, or plant room. The no-external-fan design keeps continuous noise below 40 dBA – suitable for installation adjacent to living spaces. A mounting bracket is included in the box. All cable gland entries must be correctly sealed during installation to maintain the IP rating.
