Sunsynk ACURE 3.6kW Black Single-Phase Hybrid Inverter
- 3.6 kW single-phase hybrid inverter for solar PV, 48 V battery storage and selected backup-load systems.
- Supports up to 7.2 kW PV access power across two independent MPPT trackers.
- Compatible with lead-acid and lithium-ion batteries, with self-adaption to a compatible lithium battery BMS.
Sunsynk ACURE 3.6kW hybrid inverter for solar and battery storage
The black Sunsynk ACURE 3.6kW Single-Phase Hybrid Inverter combines solar PV conversion, low-voltage battery charging and AC energy management in one IP65-rated unit. It is suitable for homes, smaller outbuildings, workshops and small single-phase sites seeking to use more on-site solar energy.
The inverter provides 3,600 W rated AC input/output active power, supports a 40–60 V battery bank and has two MPPT inputs for separate PV array orientations. It should be installed, protected and commissioned by a qualified trusted partner. [web:64]
Key features
- Flexible PV connection: two MPPT trackers, with one string per tracker and up to 7,200 W PV access power.
- 48 V battery system: works with lead-acid or lithium-ion batteries at 40–60 V, with up to 90 A charge and discharge current.
- Backup-load support: 3.6 kW rated AC power, with up to twice rated off-grid peak power for 10 seconds.
- Efficient conversion: 97.6% maximum efficiency, 96.5% European efficiency and MPPT efficiency above 99%.
- Weather-protected design: IP65 enclosure, intelligent air cooling and Type II AC and DC surge protection.
Where to use
Use the Sunsynk ACURE 3.6kW Black Single-Phase Hybrid Inverter in residential solar-and-battery systems, garden offices, workshops, farm outbuildings and modest-demand single-phase commercial applications. Its two MPPTs suit solar arrays on two roof aspects, provided the string design remains within the inverter’s voltage and current limits.
It can form part of a battery-backed power system, but battery compatibility, backup circuits, PV string sizing, earthing, protection and G98/G99 requirements must be confirmed for the site. Energian offers UK expert support and can help identify a trusted installation partner. [web:64][web:92]
