Highlights
- AC-coupling retrofit — add storage to an existing grid-tied solar system without replacing the original inverter.
- Up to 16 units in parallel for both on-grid and off-grid operation, with multiple batteries in parallel.
- Six charge/discharge time periods for tariff-aware battery scheduling (ideal for time-of-use and Amber).
- Generator input — supports storing energy from a diesel generator for backup-heavy sites.
- Colourful touch LCD, IP65 outdoor rating, and arc-fault protection (optional AFCI).
Good to know for AU installs
- Grid code AS/NZS 4777.2 — set the correct region/grid-protection profile during commissioning.
- The 3 kW and 3.6 kW models are single-MPPT; step up to the 5–6 kW models for dual-MPPT string flexibility.
- Pair with stackable 48 V LFP batteries (e.g. RW-M6.1-B, RW-F10.2, or AI-W5.1-B).
