Sungrow SH8.0RT-20 8 kW Three-Phase Hybrid Inverter

The SH8.0RT-20 is the current generation of Sungrow's RT series of three-phase hybrid inverters for homes. Its battery input covers 150-600 V, so it pairs with a wide range of high-voltage lithium-ion batteries such as Sungrow's own SBR, and it moves 10.6 kW in and out of the battery, more than its 8 kW AC rating. When the grid fails, the backup output takes over in under 20 ms and can load each phase independently, so a single-phase appliance on backup is not limited to a third of the inverter.

Key Features

• 8 kW rated AC output, three-phase 230/400 V, up to 18.6 kW drawn from the grid for charging and loads
• Two MPP trackers, 200-950 V MPPT range, 1000 V maximum input, 12.5 A per tracker
• Up to 12,000 Wp of PV
• Battery voltage 150-600 V, 30 A, 10.6 kW maximum charge and discharge power
• Backup output with under 20 ms switchover, 8 kW continuous and 12 kW for 5 minutes, 100% unbalanced load
• 98.4% maximum and 97.9% European efficiency
• Two units can run in parallel on one grid connection
• IP65, natural convection cooling, 30 dB(A), 27 kg
• Plug-and-play AC connectors and MC4 PV connectors for a quick installation

Communication covers RS485, WLAN, Ethernet and CAN for the battery, plus four digital inputs and one output for ripple control or a heat pump signal. Commissioning and monitoring are done online through Sungrow's iSolarCloud app.
