What it is
The Sunpura S6000 AC Pro is the high-power, AC-coupled member of the range. It shares the 6 kWh battery of the S6000 but uses a heavier 3,500 W Power Box and couples onto an existing solar system over AC (with dual-CT metering) rather than taking panels directly. It is built for larger retrofits where more backup power matters.
High-power retrofit for bigger homes
If a home already runs solar but needs serious storage and stronger backup, the S6000 AC Pro adds 6 kWh (expandable to 24 kWh, and up to 144 kWh with six units in parallel) with 3,500 W of continuous output and a 4,950 VA surge. The 144 kWh figure is six units, each already stacked to its full 24 kWh, joined by a parallel connection box, which is a separate product. Six base units give 36 kWh. Parallel operation is drawn across all three phases and most South African homes are single-phase, so ask us to size a multi-unit system before you plan around a headline number. Dual-band Wi-Fi with RS485 and LAN gives installers robust monitoring.
Why AC-coupled
- Retrofit-friendly: adds to an existing solar/inverter system without re-cabling the array.
- More power: 3,500 W rated, 4,950 VA peak, for larger essential loads.
- Scales high: to 24 kWh in one system, up to 144 kWh with six stacked units and a parallel box.
- Professional connectivity: dual-band Wi-Fi, Bluetooth, RS485 and LAN.
A note on cycle testing: the S6000 AC Pro cycle figure is measured at 0.5C, while the 48 V S2400 and S4800 are measured at 1.0C, so the numbers are not directly comparable.
Certification
European and international certification (CE/EMC, RED, LVD, CB, RoHS, REACH, UN38.3, IP65, WEEE, VDE 4105, EN 50549 and more). We publish this as CE and CB certification, and we claim no South African approval.
