Sunsynk Acure 7kW Black Single-Phase Hybrid Inverter
- 7 kW single-phase hybrid inverter for solar PV, 48 V battery storage and backup-power installations.
- Connect up to 14 kW of PV access power across two MPPTs, allowing flexible array design for different roof orientations.
- Works with lead-acid and lithium-ion batteries, with automatic adaptation to a compatible lithium battery BMS.
Sunsynk Acure 7kW hybrid inverter for solar and battery systems
The black Sunsynk Acure 7kW Single-Phase Hybrid Inverter combines solar generation, low-voltage battery storage and AC supply management in one IP65-rated unit. It is suited to larger homes, small commercial premises and off-grid or backup-power systems where a single-phase supply is required.
The inverter provides 7,000 W rated AC input/output power, supports up to 175 A battery charge and discharge current, and can provide off-grid peak power of twice its rated power for up to 10 seconds. Installation, commissioning and protection design should be completed by a qualified trusted partner. [file:60]
Key features
- Solar-ready: two MPPT trackers and up to 14,000 W PV access power for optimised string layouts.
- Low-voltage battery compatibility: supports 40–60 V lead-acid or lithium-ion batteries with one battery input.
- Backup capability: 7 kW rated AC power with up to two-times-rated off-grid peak power for 10 seconds.
- Efficient energy conversion: 97.6% maximum efficiency, 96.5% European efficiency and 99% MPPT efficiency.
- Outdoor-capable enclosure: IP65 protection, intelligent air cooling and an operating temperature range of -40°C to +60°C.
Where to use
Use the Sunsynk Acure 7kW hybrid inverter in single-phase solar-and-battery systems for homes, farm buildings, workshops, small offices and light-commercial premises. Its two MPPTs can suit PV arrays installed over two roof aspects, subject to voltage, current and string-design limits.
It can form part of an energy-storage and backup arrangement, but battery selection, load assessment, cable sizing, earthing and grid-connection requirements must be designed for the specific site.
