The Deye Smart Switch (SUN-SMART-SWITCH01P3) is a LoRa-connected load controller that enables intelligent automation of high-power appliances in solar energy systems. It supports both 1-phase and 3-phase grids at up to 25A, communicates wirelessly up to 200m via LoRa (863-870MHz), and integrates directly with Deye inverters for SOC-based and time-based load control. With IP65 weatherproofing and operation from -40°C to +45°C, it is designed for indoor and outdoor use.
Key features include: 25A maximum current supporting 1-phase and 3-phase grids, IP65 weatherproof rating for outdoor use, LoRa 863-870MHz wireless range up to 200m, 3 control modes (Manual, Time, SOC-Linked), Deye Cloud App remote access, and a 5-year warranty. It operates from -40°C to +45°C, making it suitable for heat pumps, pool pumps, and outdoor load-control applications.
The SUN-SMART-SWITCH01P3 operates at 220–240V AC, 50Hz, handling a maximum rated current of 25A (max power ~5,500W single-phase / ~16.5kW three-phase). Wireless communication uses LoRa at 863–870MHz with up to 200m unobstructed range. Ingress protection: IP65. Operating temperature: -40°C to +45°C. Weight: 0.4 kg. Backed by a 5-year warranty.
The Smart Switch handles any load up to 25A on 1-phase or 3-phase connections — including heat pumps, air conditioners, water heaters, pool pumps, irrigation systems, garden lighting, and EV chargers. Its IP65 weatherproofing makes it suitable for outdoor installations where a standard indoor smart plug would fail. For lighter indoor loads under 16A, the SUN-SMART-PLUG01P1-F is the alternative.
Yes. The IP65 protection rating helps protect the switch against dust and powerful water jets. It operates from -40°C to +45°C, supporting demanding outdoor conditions. Install it near a pool pump, garden irrigation controller, or outdoor heat pump unit according to local electrical rules and installation requirements.
The product documentation lists CE marking, Low Voltage Directive 2014/35/EU, EMC Directive 2014/30/EU, Radio Equipment Directive (RED) 2014/53/EU, and applicable EN safety standards for the LoRa wireless module and smart switching device. Local installation and compliance requirements should be confirmed for your market before use.
Most smart switches are limited to single-phase circuits under 16A and rely entirely on Wi-Fi. The SUN-SMART-SWITCH01P3 supports 3-phase at 25A for heavy industrial loads, uses LoRa for offline-capable control up to 200m, and integrates natively with Deye inverters for SOC-linked automation no Wi-Fi smart switch can provide. Add IP65 weatherproofing and a 5-year warranty, and it's in a completely different class.
The Deye Smart Switch includes a 5-year product warranty. Technical assistance is available via email and the Deye Cloud App. Taxes, delivery options, dispatch time, and return eligibility depend on the selected delivery region and are confirmed at checkout or by Deye Store support.
The Smart Switch supports three control modes. Manual Mode (default): ON/OFF via physical button, inverter LCD, Deye Cloud App, or web platform. Time Mode: programmable weekly schedule with physical button disabled during active schedule. SOC-Linked Mode: automatically activates or deactivates loads based on your battery's real-time State of Charge — ensuring heavy loads only run when surplus energy is available.
Yes — this is a key advantage over standard Wi-Fi smart switches. The Smart Switch maintains a direct LoRa wireless link to your Deye inverter, independent of your home network. If your router goes offline, all preset schedules and SOC-linked automation continue to operate exactly as programmed. Internet connectivity is only needed for initial setup and remote Cloud App access.
