Sunsynk Smartlynk Wireless Smart Switch SUNRX-RS01 IP65 Single Phase
The Sunsynk Smartlynk (SUNRX-RS01) is the IP65-rated, single-phase wireless smart switch designed exclusively for the Sunsynk Acure hybrid inverter range. Using the Acure's built-in LoRa radio, the Smartlynk pairs without any signal cables — tested to a reliable 200-metre range. Once paired, the inverter switches connected loads on or off automatically based on solar generation levels, battery state of charge, programmable time schedules, or grid tariff windows. One Smartlynk is included in the box with every Acure inverter; additional units can be added up to a maximum of 10 per inverter. With IP65 protection, the Smartlynk can be installed in exposed locations — outbuildings, garages, plant rooms — without an additional enclosure.

⚠ Compatibility: The SUNRX-RS01 Smartlynk is exclusively compatible with Sunsynk Acure series inverters (SunC1 and SunC2 models). It will not pair with earlier Sunsynk Classic, SYNK-SG, MAX, or ECCO series inverters. Configuration is performed via the Acure touchscreen or the Sunsynk Connect Pro app.
⚡ Single Phase: This is the single-phase (1P) Smartlynk. It controls a single-phase load circuit. Ensure the load being switched is within the 40 A rated current for the switch.
ℹ Already Included with Acure: One Smartlynk switch is supplied inside the box with every new Acure inverter purchase. This listing covers additional Smartlynk units for multi-load control applications where you need more than one switched circuit.
Key Features
LoRa Wireless — No Signal Cable
Uses the sub-GHz LoRa radio built into every Acure inverter. The low-frequency band penetrates concrete floors and masonry walls far more effectively than Wi-Fi or Bluetooth, maintaining reliable communication at distances up to 200 m.
IP65 Outdoor Rating
The IP65-rated enclosure is fully dust-tight and protected against water jets. The Smartlynk can be mounted in garages, outbuildings, plant rooms, and sheltered outdoor locations without a separate weatherproof enclosure.
40 A Relay Capacity
The 40-amp rated relay handles the most common high-consumption household loads: immersion heaters (up to 9.2 kW at 230 V), ASHP auxiliary elements, EV charge point contactors, pool pumps, and hot tub heaters.
Solar-First Load Control
Programme the Acure to energise attached loads only when excess solar generation is available, or during specified cheap-rate tariff windows. This maximises self-consumption and keeps grid draw to a minimum.
AI-Optimised via Connect Pro
When linked to Sunsynk Connect Pro, the AI engine automates switch timing based on weather forecasts, learned usage patterns, and live tariff data — removing the need for manual schedule management.
Expandable to 10 Units
A single Acure manages up to 10 Smartlynk switches simultaneously, giving system designers fine-grained control over multiple load circuits from one inverter — immersion heater, EV charger, UFH zone, pool pump, and more.

Frequently Asked Questions
Will the Smartlynk work with my existing Sunsynk inverter?
Only if your inverter is an Acure series model (SunC1 or SunC2). The SUNRX-RS01 uses the LoRa radio built exclusively into Acure inverters — it will not work with Classic, SYNK-SG, ECCO, or MAX series models.
Do I need to run signal cables between the Smartlynk and the inverter?
No signal cables are required. The Smartlynk communicates entirely via LoRa. You only need to connect a standard mains supply to the unit — the switched load connects at the Smartlynk output terminals.
What loads can I control?
Any resistive or switched single-phase load up to 40 A at 230 V. Common applications include immersion heaters, heat pump auxiliary elements, EV charge point contactors, pool pumps, hot tub heaters, and underfloor heating zone valves.
Can the inverter control the Smartlynk automatically based on solar generation?
Yes. The Acure can energise or de-energise Smartlynk switches based on excess solar generation thresholds, battery state of charge, programmed time schedules, or grid tariff windows. With Sunsynk Connect Pro, the AI layer automates this using weather forecasts and learned usage patterns.
Can the Smartlynk be installed outdoors?
Yes. The IP65-rated enclosure protects against dust ingress and water jets, making the Smartlynk suitable for outdoor mounting on sheltered walls, inside garages, outbuildings, and plant rooms without a secondary weatherproof box.
Do I need to buy this if I just purchased an Acure inverter?
No — one Smartlynk is already included in every Acure inverter box. Purchase additional units only when you need to control more than one load circuit from the same inverter.
