Powerful 8kW Output
With 8kW of rated single-phase output, the S6-EH1P8K-L-PLUS provides substantially more capacity than smaller residential hybrid inverters.
It is well suited to properties running multiple appliances simultaneously, including:
Air conditioners
Borehole and booster pumps
Refrigerators and freezers
Geysers
Pool pumps
Kitchen appliances
Home offices
Power tools
General household loads
Advanced Backup Performance
The Solis S6 Plus is designed to maintain power to essential loads when the utility grid fails.
Its 200% overload capability for up to 10 seconds provides additional short-duration power for starting demanding inductive loads such as pumps, motors and air conditioners.
With an on-grid/off-grid transfer time of less than 10ms, interruption to supported loads is kept to a minimum.
High Solar PV Capability
The S6 Plus supports PV input of up to 160% of the inverter’s rated DC power, allowing the solar array to be oversized to maximise energy generation throughout the day.
Two independent MPPTs provide greater flexibility when panels need to be installed on different roof orientations.
Each MPPT supports up to 21A PV input current, providing compatibility with modern high-power solar modules.
Low Voltage Battery Compatibility
The inverter operates with 40–60V low-voltage batteries and is compatible with a wide range of lithium-ion and lead-acid battery solutions.
This provides excellent flexibility when designing systems with different battery capacities.
Lithium battery compatibility should always be confirmed against the latest Solis battery compatibility list before installation.
Generator Integration
Generator support makes the S6 Plus particularly suitable for installations requiring extended backup capability.
The inverter supports multiple generator connection methods and automatic generator control, allowing generator power to be integrated intelligently with the solar and battery system.
Smart Load Management
Smart Load functionality provides additional control over how available energy is distributed.
The system can intelligently manage energy between:
Solar PV → Battery → Home → Grid → Generator
This can help maximise solar self-consumption while preserving stored battery energy for critical loads.
AC Coupling
The Solis S6 Plus supports connection with existing grid-tied PV inverter systems.
This makes the inverter particularly useful when upgrading an existing solar installation to include battery storage and backup functionality without necessarily replacing the complete existing PV system.
Parallel Expansion
System capacity can be expanded by operating up to 6 compatible Solis S6 Plus inverters in parallel.
This provides additional flexibility for properties where electrical demand or battery storage requirements may increase in the future.
SolisCloud Monitoring
The inverter integrates with SolisCloud for smart remote system management.
SolisCloud provides access to system information including:
Solar production
Battery operation
Grid consumption
Inverter status
Energy flow
System alarms
Remote control and optimisation
Troubleshooting information
IP66 Protection
The inverter features an IP66-rated enclosure, providing protection against dust and water ingress and making it suitable for demanding installation environments when installed according to manufacturer requirements.
Warranty
Manufacturer Warranty Included.
Warranty coverage remains subject to the applicable Solis warranty terms and conditions, correct installation, commissioning and operation.
Installation should be carried out by a suitably qualified installer, and all required commissioning and installation documentation should be retained for warranty purposes.
Ideal Applications
The Solis 8kW S6 Plus is ideal for:
Larger residential solar systems
High-consumption homes
Backup power systems
Load-shedding protection
Solar self-consumption
Battery energy storage
Generator-assisted installations
Existing solar system upgrades
Small businesses and offices
Light commercial applications
