Solis 20kW S6-EH3P20K-H Overview

The Solis 20kW S6-EH3P20K-H is built 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, the inverter can serve substantial residential and commercial loads while supporting a high-voltage lithium battery system from 120V to 800V.

A major advantage of it is that it can take on a large solar array. The inverter can handle up to 32kW of usable photovoltaic input power, the recommended maximum size for the PV array being 40kW. The system includes four MPPTs and four input strings which offer flexibility when designing the PV array.

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

Why This Hybrid Inverter Stands Out

High PV Input Capacity

The Solis 20kW S6-EH3P20K-H is able to handle a large solar array, the maximum usable PV input power being 32kW and the recommended maximum PV array size 40kW. This allows system designers to include extra PV capacity while still having a 20kW AC inverter rating.

Four MPPTs with High Current Support

The inverter has 4 MPPTs and 4 input strings, with a maximum input current of 4 times 20A and a maximum short-circuit current of 4 times 30A. This setup does offer some useful flexibility when designing strings for different roof orientations or PV sections.

High-Voltage Lithium Battery Architecture

The inverter can be used with a high-voltage energy-storage setup since it is equipped with a Li-ion battery voltage range of 120 to 800 volts. The maximum charge and discharge power is 20kW, the maximum charge and discharge current being 50A.

Fast Backup Switching

The backup output has a switching time of less than 10ms, which enables the system to move into backup operation rapidly whenever grid power is not available. The inverter can also support up to 1.6 times the rated backup power for a period of 10 seconds.

Generator and Load Management

The inverter is compatible with generators and has two backup ports which allow for intelligent management of both critical and non-critical loads. It also provides peak shaving and is capable of dealing with unbalanced and half-wave loads on both the grid and backup ports.

Best For

The Solis 20kW hybrid inverter is a strong fit 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 requires 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 required communication requirements

Solar PV Input and MPPT Performance

The section dealing with solar input is intended for use with large-capacity photovoltaic systems; the inverter has a maximum input voltage of 1000 V, a rated voltage of 600 V, a starting voltage of 160 V and an MPPT operating range from 200 to 850 V.

It includes four MPPTs and has four maximum input strings. The maximum PV input current is 4 times 20 amperes and the maximum short-circuit current is 4 times 30 amperes.

The maximum usable PV input of 32 kW should not be mistaken for the inverter’s 20 kW rated AC output. Although the greater PV capacity offers extra potential for solar input, the final string design must still stay within the maximum voltage, current, short-circuit current and MPPT operating limits.

For buyers searching for the solis 20kw inverter datasheet, the most important PV figures to check are the 1000V maximum input voltage, 200–850V MPPT range, 4 MPPTs and 4 × 20A maximum input current.

The phrase solis 20kw inverter datasheet pdf is also commonly relevant when checking the technical information required for PV string planning.

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 charge and discharge power is 20kW and the maximum charge/discharge current is 50A; the battery can be communicated with via CAN and RS485.

It is important for a high-voltage hybrid system that the battery’s communication capabilities and voltage rating are compatible, so the battery chosen should conform to the inverter’s voltage range and meet the BMS communication requirements that it supports before being installed.

For customers researching the solis 20kw hybrid inverter datasheet or solis 20kw hybrid inverter datasheet pdf, the battery voltage range, communication interface and charge/discharge limits are particularly important when selecting the storage system.

Backup Power and Load-Shedding Performance

The inverter provides a dedicated three-phase backup output with a rated output power of 20kW. Backup switching time is less than 10ms, which allows 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. The inverter also supports dual backup ports, allowing critical and non-critical loads to be managed separately.

It is useful in Pakistan since power outages can make the availability of energy stored in batteries an important factor in a solar system. Yet appropriate battery sizing is still necessary since the actual length of time that the backup supply lasts will depend on the capacity of the battery and the amount of load connected.

The inverter also allows for a phase imbalance of 100% of the maximum allowable value on both the grid side and the backup side, with the maximum power per phase being 40% of the rated power.

Generator Support and Smart Load Control

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

It is able to detect AC voltage coming from both the grid and the generator’s output in order to prevent reverse current from the grid getting to the generator. Therefore, generator integration is 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.

SG heat pump compatibility is another supported feature for suitable system applications.

Monitoring and Communication

The inverter is equipped with a 7.0-inch LCD display and also has Bluetooth and app connectivity for the purpose of monitoring the system.

Communication interfaces include:

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

Installers and system owners can use these methods of communication to keep track of the operating information and to connect the inverter with monitoring systems that are compatible.

Recommended Solar System Size

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

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

A qualified installer ought therefore to calculate the final string layout on the basis of the solar modules that have been selected and the site conditions.

Hybrid Inverter Use in Pakistan

A 20kW three-phase hybrid inverter could be useful in Pakistan’s solar market when the solar power generated during the day is to be used in conjunction with battery storage and power from the grid.

When load shedding occurs, the backup power can supply some of the loads provided that the battery has enough energy. In daylight hours, solar power can meet the needs of the connected loads and any excess energy can be used for charging the battery up to the limits of the system’s operation.

The high-voltage battery range is especially important in the case of larger storage systems, but when choosing a battery it is necessary to take into account its voltage, its charge and discharge limits as well as BMS communication.

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