SolarEdge Wireless Gateway (Master) — Wi-Fi Communication Kit with External Antenna for SetApp—
$105.76
The Story
The SolarEdge Wireless Gateway SE-WFGW-B-S1-RW is the master communication unit in SolarEdge's Wi-Fi connectivity range, wirelessly linking SetApp-enabled residential inverters to the SolarEdge monitoring platform via your home Internet router. The gateway creates a dedicated, closed Wi-Fi link directly to the inverter's built-in wireless station and connects to the router by Ethernet — so changing your home Wi-Fi password never breaks PV monitoring. The kit ships with two external antennas (one for the gateway, one for the inverter), supports up to eight SolarEdge inverters on a single wireless network, and can be extended with up to two SE-WFRPT-B-S1-RW repeaters for hard-to-reach installations. UK-spec with a BS 1363-1 plug and backed by a 5-year warranty.

⚠ SetApp-Enabled Inverters Only
The Wireless Gateway and Repeater are compatible only with SolarEdge residential inverters configured via SetApp (units featuring an onboard Wi-Fi station). Older inverters that rely on the LCD-based configuration or require a plug-in ZigBee/cellular module are not supported. Confirm your inverter's SetApp compatibility on the SolarEdge knowledge base before purchase.
⚑ Master Unit — Repeaters Sold Separately
This listing is the Wireless Gateway (Master), part SE-WFGW-B-S1-RW, which is the central unit every installation needs. If your inverter and router are more than ~50 m apart indoors or the signal must pass through multiple walls, order one or two SE-WFRPT-B-S1-RW Wireless Repeaters separately to extend coverage. The kit already includes both required Wi-Fi antennas — one for the gateway and one for the inverter, so no additional antennas are needed for a standard single-inverter install.
How the link works
The gateway forms an independent Wi-Fi connection directly to the inverter's onboard wireless station and uses a hardwired Ethernet cable to reach your home Internet router. Because that PV link is closed and separate from your home Wi-Fi, router password changes, SSID updates or guest-network reconfiguration have no effect on monitoring uptime — eliminating the most common cause of "lost" SolarEdge sites.
Dedicated PV Wi-Fi Link
A closed wireless connection between gateway and inverter that runs independently of the household router. Resilient to home Wi-Fi changes and reduces support callouts after broadband swaps.
Two Antennas In-Box
Supplied kit includes one antenna for the inverter and one for the gateway, both rated at 5 dBi gain. No need to specify or order antennas as separate line items for a single-inverter installation.
Up to Eight Inverters per Network
A single gateway can aggregate monitoring data from up to eight SolarEdge inverters on one wireless network — covering most multi-string residential and small commercial layouts without additional gateways.
Range Extension via Repeaters
Chain up to two SE-WFRPT-B-S1-RW repeaters when the inverter sits in a garage, loft or outbuilding more than 50 m from the router. Outdoor line-of-sight reach is up to 400 m per hop.
Contactless Commissioning
Installers can pair the gateway using SetApp from outside the home and leave the unit ready for the homeowner to plug in — useful for staged handovers, void-property installs and minimising on-site time.
Compact Indoor Form Factor
A 69 × 53 × 82 mm wall-plug enclosure weighing 119 g with antenna, drawing only 50 mA peak from 100–240 Vac. IP20 rating — intended for protected indoor mounting alongside the consumer unit or router.

Frequently Asked Questions
Which SolarEdge inverters work with this Wireless Gateway?
The SE-WFGW-B-S1-RW is compatible only with SolarEdge residential inverters that use SetApp commissioning — these have a built-in Wi-Fi station that the gateway pairs with. This typically includes HD-Wave single-phase inverters (SExK-RWS series) and the EnergyHub / Genesis platforms. Older inverters using the LCD-and-buttons configuration or those requiring a plug-in ZigBee or cellular module are not supported. If you're unsure, check the SolarEdge knowledge base entry for your specific inverter part number before ordering.
Do I also need to order a repeater (SE-WFRPT-B-S1-RW)?
Not in most cases. The gateway has an indoor wireless reach of around 50 m and an outdoor line-of-sight reach of up to 400 m, which covers the majority of UK residential installations where the inverter is in a garage, loft or utility cupboard within the same property as the router. Add a repeater (or two — that is the maximum supported) only when there are multiple internal walls, reinforced concrete, foil-backed insulation or significant distance between the inverter and the gateway. The repeater is the same form factor and is sold separately.
Will changing my home Wi-Fi password break my SolarEdge monitoring?
No — and this is the gateway's main advantage over having the inverter connect directly to your home Wi-Fi. The link between the inverter and the gateway is a dedicated, closed wireless network with its own SSID and credentials, completely independent of your household Wi-Fi. The gateway then talks to your router over a wired Ethernet cable. Router password changes, broadband swaps, SSID renames or guest-network reconfiguration have no effect on the PV monitoring link. This eliminates the most common service callout for SolarEdge sites.
How does this compare with a ZigBee or cellular communication kit?
The Wi-Fi Gateway is positioned by SolarEdge as the enhanced alternative to the ZigBee Gateway: it does not require a plug-in card inside the inverter and uses widely available 802.11 b/g/n hardware instead of proprietary ZigBee radios. It needs an Ethernet path to your router, which is generally cleanest in a single-property home. Cellular communication kits remain the go-to option for off-grid sites or sites without any local broadband — but where home Internet is available, Wi-Fi via this gateway is usually simpler to deploy and avoids ongoing SIM costs.
Can the gateway be installed outdoors or in an unheated garage?
The unit is rated IP20, so it is intended for protected indoor use only — outdoor installation or exposure to dripping water is not permitted. Operating temperature is rated from −20 °C to +60 °C, so a typical UK garage, plant room or utility cupboard is fine provided the unit is dry and dust-protected. The gateway draws very little power (50 mA peak from a 100–240 Vac wall outlet) so a standard UK 13 A socket is more than adequate.
How many inverters can a single gateway support?
Up to eight SolarEdge SetApp-enabled inverters can share one wireless gateway on a single network. There are three supported topologies: a single inverter connected wirelessly (with optional repeaters); multiple inverters where one inverter talks to the gateway over Wi-Fi and the rest are daisy-chained on an RS485 bus; or multiple inverters each communicating directly over Wi-Fi (point-to-multipoint). In the third scenario, additional inverter antennas must be purchased separately — the kit only includes one inverter-side antenna.
