Sunsynk Acure 5kW Black Single-Phase Hybrid Inverter
- 5 kW single-phase hybrid inverter for solar PV, 48 V battery storage and selected backup-load applications.
- Supports up to 10 kW PV access power through two MPPT trackers, allowing flexible solar-array layouts.
- Compatible with lead-acid and lithium-ion batteries, with BMS self-adaption for supported lithium battery systems.
Sunsynk Acure 5kW hybrid inverter for solar and battery storage
The black Sunsynk Acure 5kW Single-Phase Hybrid Inverter combines solar PV conversion, low-voltage battery charging and AC power management in an IP65-rated enclosure. It is suited to homes, farm buildings, workshops, small offices and light-commercial single-phase sites.
The unit provides 5,000 W rated AC input/output active power and up to 120 A battery charge or discharge current. Its two MPPT inputs support solar arrays across different roof orientations, subject to the stated PV voltage, current and string limits. [web:64]
Key features
- Two MPPT trackers: supports two strings per MPPT and up to 10,000 W PV access power.
- 48 V battery connection: suitable for lead-acid or lithium-ion batteries within a 40–60 V operating range.
- Backup capability: delivers 5 kW rated AC power and up to two-times-rated off-grid peak power for 10 seconds.
- Efficient conversion: maximum efficiency of 97.6%, European efficiency of 96.5% and MPPT efficiency above 99%.
- Protected enclosure: IP65 rating, Type II AC and DC surge protection, and intelligent air cooling.
Where to use
The Sunsynk Acure 5kW Black Single-Phase Hybrid Inverter is appropriate for solar self-consumption and battery-storage systems at houses, outbuildings, agricultural buildings, small retail units, workshops and offices with a single-phase electricity supply.
It can form part of a battery-backed supply arrangement, but it is not an out-of-the-box installation. A trusted qualified partner should confirm battery compatibility, backup-load requirements, PV string design, earthing, protection and applicable G98/G99 grid-connection requirements.
