⚠ Installer Notice: The Sunsynk Acure must be installed by a qualified electrical installer. Warranty registration must be completed within 7 days of commissioning — failure to register may void the warranty.
⚡ Compatibility Note: Designed for low-voltage (LV) 48 V battery systems (40–60 V bus). Compatible with lithium-ion and lead-acid batteries via self-adapting BMS. UK grid approval: G98/G99. Wireless CT (SUNCT-RS03) and Smartlynk switch (SUNRX-RS01) sold separately — up to 2 CTs and 10 smart switches per inverter.
ℹ About the Sunsynk Acure C1: The SunC1 is the compact Acure chassis (376×530×276 mm, naturally cooled), covering 3.6–6 kW. Every Acure includes built-in Arc Fault Detection (AFCI), LoRa wireless, a colour touchscreen, a multi-colour LED status strip, Wi-Fi, Bluetooth and LAN, plus a 40 A Smartlynk wireless switch in the box.
Key Features
Dual MPPT, 500 V
Two independent MPPT trackers accept strings up to 500 V open-circuit, each handling 18+18 A operating current — ideal for separate roof aspects with no cross-shading losses.
LoRa + Wi-Fi + LAN Built In
LoRa, Wi-Fi, Bluetooth and Ethernet are all standard — no external data logger dongle needed. LoRa communicates with wireless CTs and Smartlynk switches at up to 200 m.
Built-In AFCI & Theft Alarm
Arc Fault Circuit Interrupter and solar panel tamper detection are factory-integrated. The multi-colour LED strip on the front face provides instant at-a-glance system status.
IP65 Outdoor Rated
The IP65-rated cabinet is dust-tight and water-jet resistant, supporting outdoor wall mounting without additional weatherproofing.
Natural Convection Cooling
The C1 chassis uses fanless natural convection cooling — no moving parts, no noise, and no maintenance. Operating range is –40 to +60°C with derating above 45°C.
40A Smart Switch Included
Every Acure ships with one 40 A Smartlynk wireless relay in the box, ready to control immersion heaters, EV chargers, or other loads from day one.
2× Rated Peak Power
Off-grid surge capability of 2× rated output for 10 seconds handles motor start-up loads — fridges, pumps, compressors — without nuisance trips.
5-Year Warranty (10 with Battery)
Standard 5-year inverter warranty. Pair with any compatible Sunsynk battery and the warranty extends to 10 years.
