Key Features
- 8kW rated three phase output.
- Two MPPT trackers for PV array design.
- Self-consumption and timed charging modes.
- Dedicated backup output with transfer in less than 40ms.
- IP65 enclosure with natural convection cooling.
- Seamlessly integrates with Dyness Stack100 S51100 battery (2 to 8 battery modules), Pylontech Force H2 and Force H3 high voltage batteries, providing flexibility for various setups.
Where to Use
For homes and small businesses with a three phase supply and compatible high voltage battery storage. Backup loads and per-phase demand must be checked as part of the installation design.
