Solis 20kW S6 HV Three Phase Hybrid Inverter

Solis 20kW Hybrid Inverter Overview

The Solis 20kW S6-EH3P20K-H is designed for three-phase solar systems where high PV capacity, battery storage and dependable backup operation need to work together. With a 20kW rated AC output, this inverter can serve substantial residential and commercial loads while supporting a high-voltage lithium battery system from 120V to 800V. If you are looking for the Solis 20kW hybrid inverter price in Pakistan, this model offers a powerful solution for three-phase solar systems.

One major advantage is its ability to accommodate a large solar array. The inverter supports up to 32kW of maximum usable photovoltaic input power, with a recommended maximum PV array size of 40kW. In addition, its four MPPTs and four input strings provide flexibility when designing the solar array.

For backup applications, the inverter provides a dedicated backup output with less than 10ms switching time. It also supports up to 1.6 times rated power for 10 seconds. Furthermore, generator integration, dual backup ports for critical and non-critical loads, peak shaving and unbalanced load support make this model suitable for demanding installations.

Why the Solis 20kW Hybrid Inverter Stands Out

High PV Input Capacity

The Solis 20kW S6-EH3P20K-H can accommodate a large solar array, offering 32kW maximum usable PV input power and a 40kW recommended maximum PV array size. This capacity allows system designers to include additional PV capacity while maintaining the inverter’s 20kW AC output rating.

Four MPPTs with High Current Support

The inverter features 4 MPPTs and 4 input strings. Each MPPT supports a maximum input current of 20A, while the maximum short-circuit current is 30A per MPPT. As a result, installers have flexibility when designing solar strings for different roof orientations and PV sections.

High-Voltage Lithium Battery Architecture

The inverter supports a high-voltage Li-ion battery system with an operating voltage range of 120–800V. It provides a maximum charge and discharge power of 20kW, along with a maximum charge and discharge current of 50A. Battery communication is supported through CAN and RS485 interfaces.

Fast Backup Switching

The backup output has a switching time of less than 10ms, allowing the system to move into backup operation quickly when grid power becomes unavailable. Moreover, the inverter supports up to 1.6 times its rated backup power for 10 seconds.

Generator and Load Management

The inverter supports generator integration and features dual backup ports for managing critical and non-critical loads separately. It also provides peak shaving and supports unbalanced and half-wave loads on both the grid and backup ports.

Best For

The Solis 20kW Hybrid Inverter is a suitable option for:

• Large residential solar systems with three-phase loads.
• Commercial buildings requiring solar, battery and backup integration.
• Systems with substantial daytime solar consumption.
• Buyers planning high-voltage lithium battery storage.
• Installations requiring generator backup support.
• Solar systems where critical and non-critical loads need separate management.
• Projects requiring a comparatively large PV array around a 20kW AC inverter.
• Areas affected by frequent grid interruptions and load shedding.

Not Ideal For

This inverter may not be the right choice where:

• A single-phase inverter is required.
• The project needs a low-voltage battery architecture.
• The intended PV array exceeds the inverter’s electrical limits.
• The system only needs a basic on-grid inverter without battery storage or backup functionality.
• The selected battery does not meet the 120–800V range or the required communication requirements.

Solar PV Input and MPPT Performance

The solar input section is designed for large-capacity photovoltaic systems. The inverter has a maximum input voltage of 1000V, a rated PV voltage of 600V, a startup voltage of 160V and an MPPT operating range of 200–850V.

It includes four MPPTs and four maximum input strings. The maximum PV input current is 20A per MPPT, while the maximum short-circuit current is 30A per MPPT.

The 32kW maximum usable PV input should not be confused with the inverter’s 20kW rated AC output. Although the higher PV capacity offers additional potential for solar input, the final string design must remain within the maximum voltage, current, short-circuit current and MPPT operating limits.

These specifications are important when planning solar panel strings. In particular, installers should check the maximum input voltage, MPPT operating range, number of MPPTs and maximum input current before finalising the PV configuration.

Battery Compatibility and Energy Storage

The Solis 20kW S6-EH3P20K-H uses a high-voltage Li-ion battery architecture with a battery voltage range of 120–800V.

The maximum battery charge and discharge power is 20kW, while the maximum charge and discharge current is 50A. The inverter supports battery communication through CAN and RS485.

For a high-voltage hybrid system, the selected battery’s voltage rating and communication capabilities must be suitable. Therefore, check that the battery operates within the inverter’s voltage range and meets the required BMS communication requirements before installation.

The battery voltage range, communication interfaces and charge/discharge limits are particularly important when selecting an energy storage system for the Solis 20kW Hybrid Inverter.

Backup Power and Load-Shedding Performance

The inverter provides a dedicated three-phase backup output with a rated output power of 20kW. Its backup switching time is less than 10ms, allowing the system to move to backup operation quickly during a grid outage.

The backup output supports up to 1.6 times rated power for 10 seconds. In addition, the inverter features dual backup ports, allowing critical and non-critical loads to be managed separately.

This feature is useful in Pakistan, where power outages can make stored battery energy an important part of a solar system. However, appropriate battery sizing is still necessary because the actual backup duration depends on battery capacity and the amount of connected load.

The inverter also supports phase imbalance on both the grid and backup sides. The maximum power per phase is 40% of rated power, within the stated operating limits.

Generator Support and Smart Load Control

The Solis 20kW S6-EH3P20K-H supports generator input, with a maximum generator input power of 20kW.

It can detect AC voltage from both the grid and generator output to help prevent reverse current from reaching the generator. Therefore, generator integration can be a useful option when extended backup operation is required.

The inverter also supports peak shaving, allowing the hybrid system to manage energy use more strategically where reducing grid-side peak demand is important.

Additionally, SG heat pump compatibility is available for suitable system applications.

Monitoring and Communication

The inverter features a 7.0-inch LCD display, along with Bluetooth and app connectivity for system monitoring.

Its communication interfaces include:

• CAN
• RS485
• Ethernet
• Optional Wi-Fi
• Optional Cellular
• Optional LAN

These communication options help installers and system owners monitor operating information and connect the inverter with compatible monitoring systems. Furthermore, the available interfaces provide flexibility when planning system monitoring and communication.

Recommended Solar System Size

The 20kW AC output and 40kW recommended maximum PV array size refer to two different aspects of system design.

The inverter supports up to 32kW of maximum usable PV input power, while the recommended maximum PV array size is 40kW. However, the system should not be designed around the maximum array figure alone. PV module Voc, Isc, MPPT voltage, input current, temperature-related voltage changes and string configuration must all remain within the inverter’s limits.

Therefore, a qualified installer should calculate the final PV string layout according to the selected solar modules and site conditions.

Hybrid Inverter Use in Pakistan

A 20kW three-phase hybrid inverter can be useful in Pakistan’s solar market when users want to combine daytime solar generation with battery storage and grid electricity.

During daylight hours, solar power can supply connected loads. Any available excess energy can also charge the battery within the system’s operating limits. During load shedding, the backup output can supply connected loads as long as the battery has enough stored energy.

The high-voltage battery range is particularly important for larger storage systems. However, buyers should also consider battery voltage, charge and discharge limits, and BMS communication when selecting a suitable battery.

The inverter has an IP66 ingress protection rating and an operating temperature range of -25°C to +60°C. Even with this protection level, correct installation remains important. Adequate ventilation, suitable electrical protection, correct cable sizing and professional commissioning should all be part of the installation.
