S6-EH3P20K-H - Three-phase hybrid inverter 20 kW for HV batteries

S6-EH3P20K-H is a 20 kW three-phase hybrid inverter for high-voltage lithium-ion batteries (120-800 V), with 4 MPPT inputs, a 7-inch LCD and Bluetooth app configuration. It combines solar conversion, battery charging and load supply in one unit and can run in parallel, up to 6 units, in grid-connected or off-grid systems.

Main features:

  • AC rated power: 20000 W
  • HV battery: 120-800 V, lithium-ion, max. current 50 A
  • PV input: 4 MPPT, 200-850 V, maximum 32000 W
  • Maximum efficiency: 97.7%
  • Communication: Wi-Fi, LAN, Bluetooth, CAN, RS485
  • Protection and cooling: IP66, redundant fans
  • Parallel operation: Up to 6 units

The inverter connects to high-voltage lithium-ion batteries in the 120-800 V range, with a single battery port, communicates with the battery over CAN or RS485 and is compatible with the HV batteries of the brands in the manufacturer compatibility list, for example BYD, Dyness or Pylontech. The recommended PV array size is up to 40 kW, of which a maximum of 32000 W can be used, on 4 MPPT inputs with one string each (20 A maximum and 30 A short-circuit current per input), with a maximum voltage of 1000 V and a start-up voltage of 160 V.

The three-phase output accepts unbalanced loads, with up to 40% of the rated power on each phase, and the switchover from grid to backup supply takes less than 10 ms. In off-grid mode the backup output withstands 1.6 times the rated power for 10 s. The inverter can be AC-coupled to an existing PV installation, and a generator connects to the dedicated port, with a maximum input power of 20 kW.

Up to 6 units of the same model can be connected in parallel, and remote monitoring and control are done through the SolisCloud platform. The package includes an Eastron meter with 3 current transformers (CT) and a data logging stick. The IP66 enclosure operates from -25 °C to +60 °C and at altitudes up to 2000 m.
