Powerful 12kW Hybrid Energy Core

The Solis S6-EH1P-12K-L-PLUS provides a 12kW rated AC output, giving it the capacity to support larger electrical loads than conventional residential hybrid inverters.

The system integrates:

• Solar PV generation
• Battery energy storage
• Grid electricity
• Backup power
• Generator support

This allows the inverter to intelligently manage different energy sources according to system requirements.

For homes and businesses facing high electricity costs or unreliable grid power, the system can increase solar self-consumption while providing battery backup during outages.

48V Low-Voltage Battery Compatibility

The S6-EH1P-12K-L-PLUS is built around a 48V low-voltage battery architecture.

It supports compatible:

• LiFePO₄ lithium batteries
• Lead-acid batteries
• Low-voltage battery storage systems
• Lithium BMS communication

This provides flexibility when designing a new solar system or expanding an existing installation.

The inverter’s smart charging and discharge management helps optimize battery utilization while maintaining reliable backup power.

160% PV Oversizing

The Solis 12kW hybrid inverter supports up to 160% DC PV oversizing, allowing a significantly larger solar array to be connected within the manufacturer’s specified electrical limits.

According to the supplied specifications:

Maximum PV Input Power: Up to 24,000W

Usable PV Power: Up to 19,200W

This high PV capacity allows the inverter to take advantage of larger solar arrays and maximize solar production throughout the day.

PV oversizing can be particularly useful when actual panel production is reduced by cloud cover, temperature, orientation, shading, or other environmental factors.

Three Independent MPPTs & Six PV String Inputs

The S6-EH1P-12K-L-PLUS is equipped with 3 independent MPPT trackers and 6 PV string inputs.

According to the supplied specifications, the system supports:

• 3 independent MPPTs
• 6 PV string inputs
• Up to 20A per string
• Up to 160% DC PV oversizing

Multiple MPPTs provide greater flexibility when designing solar arrays with different roof orientations, panel configurations, or operating conditions.

Each MPPT can independently optimize the connected PV array, helping maximize energy harvesting under varying sunlight conditions.

21A PV Input Capability

The inverter supports high-current PV modules, with the supplied product information specifying up to 21A PV input current.

This makes it suitable for modern high-power solar panels and gives installers greater flexibility when designing contemporary PV systems.

200% Off-Grid Overload Capability

The Solis 12kW inverter supports 200% overload for up to 10 seconds in off-grid mode.

This capability is useful when powering appliances that require significantly higher current during startup.

Suitable applications can include:

• Water pumps
• Air conditioners
• Refrigerators
• Electric motors
• Other high-startup loads

The short-duration overload capability helps the inverter handle demanding startup conditions without requiring the entire system to be oversized solely for temporary surge loads.

Under 10ms Grid-to-Backup Switching

The S6-EH1P-12K-L-PLUS supports on/off-grid switching in under 10 milliseconds.

When grid electricity becomes unavailable, the inverter can rapidly transition to backup operation.

This helps minimize interruption to connected equipment and is particularly useful for:

• Homes
• Offices
• Shops
• Businesses
• Network equipment
• Security systems
• Other critical loads

Smart Load Management

The inverter features smart load management, allowing available solar and battery energy to be managed more efficiently.

During a power outage, critical loads can be prioritized to help extend battery backup duration.

This is particularly valuable for larger installations where users may want to keep essential appliances operating while temporarily disconnecting non-essential loads.

Customizable Battery Backup

The S6-EH1P-12K-L-PLUS supports a customizable battery backup level.

Users can configure the system to maintain a reserve of battery energy rather than completely discharging the battery during normal operation.

This allows stored energy to be preserved for unexpected power outages.

PV-Only Off-Grid Operation

The inverter supports PV-only off-grid operation, providing additional flexibility for suitable solar installations.

This can be useful for applications where customers want to prioritize solar generation and potentially add battery storage at a later stage, subject to system configuration and manufacturer requirements.

Grid-Tied PV Support

The Solis 12kW hybrid inverter supports existing PV grid-tied power connections for export control and off-grid applications.

This makes it suitable for customers looking to upgrade or expand an existing solar installation with battery-storage and backup functionality.

SolisCloud Smart Monitoring

The inverter supports SolisCloud, Solis’ smart monitoring platform.

Users can monitor system performance remotely and access information relating to:

• Solar generation
• Battery status
• Energy consumption
• Grid operation
• System performance
• Fault information

SolisCloud also supports remote control, optimization, and troubleshooting capabilities.

This is particularly useful for solar installers and businesses managing systems remotely.

7-Inch Industrial-Grade Touchscreen

The S6-EH1P-12K-L-PLUS features a 7-inch industrial-grade touchscreen.

The large display provides a convenient interface for viewing system information and managing available settings directly from the inverter.

This makes local operation easier for homeowners, businesses, and technicians.

Generator Integration

The inverter supports multiple generator connection methods and automatic generator control.

A generator can therefore be integrated as an additional backup source for applications requiring extended backup capability.

This makes the inverter particularly suitable for areas where grid interruptions can last for extended periods.

High Conversion Efficiency

The supplied product specifications state a maximum conversion efficiency of up to 97–98%.

High conversion efficiency helps reduce energy losses when converting electricity between the solar PV, battery, and AC electrical systems.

Actual efficiency will vary depending on load, operating conditions, PV configuration, battery characteristics, and installation design.

Intelligent Cooling & Protection

The Solis S6-EH1P-12K-L-PLUS uses intelligent fan-assisted cooling to help maintain appropriate operating temperatures.

The inverter also incorporates multiple protection mechanisms, including:

• Anti-islanding protection
• Overload protection
• Short-circuit protection
• Over-temperature protection
• Over-voltage protection
• Over-current protection

These features help safeguard the inverter and connected equipment when properly installed and configured.

IP66 Protection

The inverter features an IP66 ingress protection rating, providing protection against dust ingress and powerful water jets when installed according to manufacturer specifications.

This makes the inverter suitable for demanding operating environments.
