Solis 6kW Single-Phase Low Voltage Hybrid Inverter – S6-EH1P6K-L-PLUS
Model: S6-EH1P6K-L-PLUS Brand: Solis Rated Power: 6kW Phase: Single Phase Battery Type: 40–60V Low Voltage Type: Hybrid Solar & Battery Inverter Warranty: Manufacturer Warranty Included (10years) Product Overview The Solis S6-EH1P6K-L-PLUS 6kW Hybrid Inverter is a powerful next-generation single-phase energy storage inverter designed for residential and light commercial solar installations. Combining solar PV, battery storage, grid power and generator integration in one intelligent system, the S6 Plus provides excellent flexibility for backup power, self-consumption and energy management. Its 40–60V low-voltage battery architecture makes it compatible with a wide range of lithium and lead-acid battery solutions. With high PV input capability, dual MPPTs, fast backup switching and powerful off-grid overload capability, the Solis S6 Plus is an excellent choice for modern South African solar installations. Key Features 6kW single-phase hybrid inverter 40–60V low-voltage battery system Compatible with multiple lithium and lead-acid battery brands 2 independent MPPTs Up to 21A PV input current per MPPT Supports PV input capacity of up to 160% 200% overload capability for 10 seconds in off-grid operation Fast on-grid/off-grid transfer of less than 10ms Generator connection and automatic generator control support Smart Load management Supports AC coupling with existing grid-tied PV systems Supports parallel operation of up to 6 inverters Grid-tied and off-grid operation Customisable battery backup reserve PV-only off-grid operating capability Large 7-inch display IP66 protection rating SolisCloud remote monitoring and management Suitable for residential and light commercial installations Advanced Backup Performance The S6-EH1P6K-L-PLUS is designed to provide reliable backup power during grid failures. Its high overload capability allows the inverter to handle demanding startup loads such as: Pumps Refrigerators and freezers Air conditioners Electric motors Power tools Household appliances The inverter can provide up to 200% overload for 10 seconds in off-grid mode, helping it handle short-duration startup surges from inductive loads. Solar PV Performance The Solis S6 Plus platform supports PV array oversizing of up to 160% of the inverter’s rated DC power, allowing installers to maximise available solar production throughout the day. The dual-MPPT design also makes the inverter suitable for installations where solar panels are split between different roof orientations. Each MPPT supports PV input current of up to 21A, improving compatibility with modern high-current solar modules. Battery Compatibility The inverter operates with 40–60V low-voltage battery systems and supports a wide selection of compatible lithium-ion and lead-acid batteries. This gives homeowners and installers greater flexibility when selecting battery capacity and allows systems to be expanded as energy-storage requirements increase. Battery compatibility should always be confirmed against the latest Solis approved battery compatibility list before installation. Generator Support The S6 Plus provides flexible generator integration, making it particularly useful for properties requiring additional backup during prolonged grid outages. Generator functionality can be incorporated into the system for automatic control and intelligent energy management. Smart Energy Management The inverter can intelligently manage power between: Solar PV → Battery → Home → Grid → Generator Smart Load functionality can be used to prioritise selected loads and improve available backup duration. Existing grid-tied solar installations can also be integrated through AC coupling, making the S6 Plus suitable for system upgrades. Parallel Expansion Need more power in the future? The S6 Plus platform supports parallel operation of up to six compatible units, allowing system capacity to be increased as the property’s electrical requirements grow. Monitoring Integration with SolisCloud provides remote system monitoring and management, allowing system performance, solar production, battery operation and inverter status to be monitored remotely. Protection & Build Quality With an IP66 enclosure, the inverter is designed for demanding installation environments while providing protection against dust and water ingress. The system incorporates comprehensive inverter, battery and grid protection functionality for reliable long-term operation. Warranty Manufacturer Warranty Included.
