Description
The Deye SUN-29.9K-SG01HP3-AU-BM3 is a 29.9kW three-phase hybrid inverter for commercial properties, farms and larger solar-and-battery installations. It manages solar generation and compatible high-voltage lithium battery storage, with grid-connected and off-grid operating modes available in a correctly designed system.
Key features
- 29.9kW rated AC output for three-phase energy systems.
- 3 independent MPPTs to support flexible solar-array design.
- High-voltage lithium battery connection: 160–800 V DC, with 50 a + 50 a (two battery inputs).
- AC coupling for suitable existing solar systems, plus support for storing energy from a diesel generator.
- Six programmable periods for battery charging and discharging.
- Up to 10 inverters in parallel for supported on-grid or off-grid system designs.
- IP65 enclosure and a manufacturer-listed 10-year warranty, subject to Deye warranty terms.
