Powerful 12kW Three-Phase Output
With 12kW of three-phase output, the Solis S6 LV Hybrid is an excellent solution for properties requiring balanced three-phase power and battery backup.
Typical applications include:
Large residential properties
Farms and smallholdings
Workshops
Offices
Retail premises
Borehole and booster pumps
Three-phase motors
Air-conditioning systems
Pool equipment
Refrigeration
Light commercial installations
Actual motor and equipment compatibility must be confirmed according to running current, starting current and inverter overload capability.
48V Low-Voltage Battery System
One of the major advantages of this inverter is its 48V low-voltage battery architecture.
The inverter is designed to work with a variety of compatible lithium and lead-acid battery brands, providing greater flexibility when selecting battery storage capacity.
This makes it possible to configure the system according to the customer’s required:
Backup duration
Daily energy consumption
Maximum battery discharge power
Future expansion requirements
Always confirm the exact battery make and model against the latest Solis battery compatibility documentation.
High Solar PV Capability
The Solis S6 three-phase LV range supports PV input of up to 160% of the inverter’s rated DC power.
This allows the PV array to be oversized to improve solar production during mornings, afternoons and lower-irradiance conditions.
The inverter is also designed for compatibility with modern high-power PV modules.
Three-Phase Unbalanced Load Support
The inverter supports three-phase unbalanced loads, an important feature for residential and commercial properties where consumption is rarely distributed perfectly evenly across L1, L2 and L3.
This provides greater flexibility when supplying real-world three-phase electrical installations.
Generator Integration
Generator compatibility allows an additional backup energy source to be incorporated into the system.
This is particularly useful for:
Farms
Businesses
Areas experiencing extended utility outages
Sites requiring extended backup autonomy
Properties with large battery banks
When correctly configured, generator power can form part of the property’s overall energy-management strategy.
Backup Power
UPS-level switching helps maintain power to supported loads when utility power fails.
Combined with a correctly sized battery bank, the 12kW inverter can provide substantial three-phase backup capability during grid outages.
AC Coupling
The Solis S6 LV Hybrid supports coupling with an existing grid-tied PV system.
This makes it an attractive solution when upgrading an existing solar installation to add:
Battery storage
Backup power
Additional energy management
Generator integration
Parallel Expansion
Up to 6 compatible Solis inverters can be operated in parallel, providing a scalable solution for installations where additional capacity may be required.
This makes the platform suitable for both current requirements and future system expansion.
PV-Only Off-Grid Operation
The inverter supports PV-only off-grid operation, allowing certain system designs to operate without initially installing battery storage.
This provides additional flexibility when designing systems around customer budgets and future expansion plans.
SolisCloud Monitoring
SolisCloud provides intelligent remote monitoring and management of the installation.
Users and installers can monitor:
Solar PV generation
Battery state of charge
Battery charging and discharging
Property consumption
Grid import and export
Inverter status
Energy-flow information
Historical performance
System alarms and warnings
IP66 Protection
The inverter carries an IP66 ingress-protection rating, providing strong protection against dust and water ingress when installed according to manufacturer requirements.
Ideal Applications
The Solis 12kW Three-Phase LV Hybrid Inverter is ideal for:
Large residential properties
Three-phase homes
Farms and smallholdings
Workshops
Offices
Retail premises
Backup power systems
Solar self-consumption
Generator-assisted installations
Large battery-storage systems
Light commercial solar installations
