Couldn't load pickup availability
The Solis S6-EH1P3K-L-PLUS is a single-phase hybrid inverter with a rated AC output of 3 kW, designed for residential energy storage with 48V Low Voltage batteries. The inverter features two independent MPPT inputs with a maximum input current of 16A each, suitable for modern 182mm solar panels and installations with multiple roof orientations. The backup output switches in less than 4 ms upon grid failure. The system supports generator connection, AC coupling of existing PV inverters and parallel operation of up to 6 inverters for microgrid applications. Battery communication is via CAN or RS485.
- 16A MPPT input current: suitable for modern 182mm solar panels, recommended maximum PV power 6 kW, usable PV input power 4.8 kW.
- Backup switchover time under 4 ms: UPS-level backup function for uninterrupted supply of critical loads during grid failure.
- 200% overload capability for 10 seconds: supports inductive loads such as pumps and compressors during backup operation.
- Dual backup output: separate control of critical and non-critical loads via two backup ports.
- Generator support: integrated control for external generators via GEN port or grid connection, including automatic start/stop based on battery SOC.
- Parallel operation: up to 6 inverters in parallel for microgrid applications, including three-phase system formation.
- IP66 and natural cooling: suitable for outdoor and indoor installation, silent fanless operation.
Energy management with 3 kW backup and generator support (Solis)
The S6-EH1P3K-L-PLUS acts as a central energy hub switching between grid, PV, battery, generator and backup loads. In self-consumption mode, PV power takes priority over battery and grid. Upon grid failure, the inverter switches to the backup output in less than 4 ms. The Smart Port supports three configurations: generator input, AC coupling of an existing PV inverter or Smart Load output for intelligent load control. Export limitation and Time-of-Use settings are configurable via the 7-inch LCD display or the Soliscloud app via Bluetooth.
The inverter is compatible with 48V Low Voltage Li-ion and lead-acid batteries from brands including Dyness, Pylontech and BYD. Verify the exact battery model, BMS version and communication cable via the official Solis Battery Matching Compatibility List before commissioning.

Which batteries are compatible with the Solis S6-EH1P3K-L-PLUS?
The inverter works with 48V Low Voltage Li-ion and lead-acid batteries in the voltage range of 40–60 V via CAN or RS485. Compatible brands include Pylontech (US2000C, US3000C, US5000), Dyness and BYD (LVS series). Verify the exact battery model, BMS version and CAN pin assignment via the official Solis Battery Matching Compatibility List before commissioning. Set the battery model correctly via the LCD display or the Soliscloud app.
How does the backup function and generator support work on the Solis S6-EH1P3K-L-PLUS?
Upon grid failure, the inverter switches to the backup output in less than 4 ms. The system supports a peak power of 200% of rated power for 10 seconds, allowing inductive loads such as pumps and compressors to start. The dual backup output enables separate control of critical and non-critical loads. The Smart Port (GEN port) supports three configurations: generator input (automatic start/stop based on battery SOC), AC coupling of an existing PV inverter via Freq-Watt control, or Smart Load output for intelligent load management. The backup output must not be connected to the public grid.
Is the Solis S6-EH1P3K-L-PLUS suitable for Time-of-Use and self-consumption optimisation?
The inverter supports Time-of-Use settings with configurable charge and discharge time slots, allowing the battery to charge during low-tariff periods and discharge during peak-tariff hours. In self-consumption mode, PV power is prioritised for household loads, with surplus energy stored in the battery. In combination with a suitable 48V battery such as the Pylontech US5000 or the Dyness Tower Pro, the system structurally reduces grid dependency and lowers energy costs.
