Solis 50kW S6 High Voltage Three Phase Hybrid Inverter Overview

The Solis 50kW S6 High Voltage Three Phase Hybrid Inverter is built for solar energy systems where daytime PV generation, battery storage, grid supply and backup power need to work together. Its 50kW rated output makes it suitable for larger commercial and high-demand three-phase installations rather than small residential systems.

One of the main advantages of this model is its high capacity for handling photovoltaic power. It has a recommended maximum PV array size of 100kW and a maximum usable PV input of 96kW, which provides system designers with plenty of room for incorporating solar generation and for charging the battery. The inverter is equipped with 4 MPPTs and can handle up to 8 PV strings, enabling the PV array to be spread out over several independently tracked inputs.

The system uses a high-voltage Li-ion battery design ranging from 150 to 800 volts, having two battery inputs and a maximum charge and discharge capacity of 70 amperes times 2. On the backup side, the output is rated at 50kW, with a switching time of less than 10 milliseconds and a peak power of up to 1.6 times the rated power for a duration of 2 seconds.

Why This Hybrid Inverter Stands Out

High PV Input Capacity

The inverter can accommodate a recommended 100kW PV array while its maximum usable PV input is 96kW. This high DC-to-AC design allows more solar generation to be connected to a 50kW inverter, particularly where strong daytime solar production and battery charging are important.

Four MPPTs and Eight PV Strings

The system, featuring 4 MPPTs and a maximum of 8 PV strings, offers more flexibility when it comes to larger PV installations. Separate MPPT inputs can be used to handle different roof sections or array orientations, provided that the string voltage and current are properly designed.

High-Voltage Battery Architecture

The 150–800V battery voltage range is designed around high-voltage lithium-ion energy storage. Two battery inputs are available, with maximum charge/discharge current of 70A × 2.

Fast Backup Switching

The backup output has a rated power of 50kW and a backup switch time of less than 10 ms, which means that the inverter can be used in systems in which certain loads require a quick shift to backup operation when the grid supply is not available.

Outdoor-Ready IP66 Protection

An IP66 ingress protection rating provides a higher level of protection against dust and water ingress. The inverter also uses intelligent fan cooling and supports an operating ambient temperature range of -25°C to +60°C.

Best For

The Solis 50kW hybrid inverter is a strong fit for:

• Commercial solar systems with substantial daytime electricity demand.
• Large three-phase installations requiring battery backup.
• Projects designed around high-voltage lithium-ion batteries.
• Solar systems where a larger PV array is required relative to inverter AC capacity.
• Sites affected by load shedding that need a substantial backup output.
• Installations requiring generator integration alongside solar and battery storage.
• Projects where multiple PV orientations benefit from 4 MPPTs and 8 strings.
• Businesses looking to use more daytime solar generation while storing excess energy for later use.

Not Ideal For

This model may not be the right choice where:

• The project requires a single-phase inverter.
• The selected battery does not meet the inverter’s 150–800V lithium-ion battery requirements.
• The project only needs a simple on-grid inverter without battery storage or backup functionality.
• The required PV array or electrical system exceeds the inverter’s specified voltage, current or power limits.
• A low-voltage battery architecture is specifically required.
• The installation does not have sufficient space or suitable conditions for a 73kg commercial inverter.

Solar PV Input and MPPT Performance

The PV side is designed for large solar arrays. The inverter supports a maximum DC voltage of 1000V, with a 600V rated voltage. Its MPPT operating range is 150–850V, while the PV start-up voltage is 180V.

The Solis 50kW hybrid inverter datasheet specifies 4 MPPTs with up to 8 maximum input strings for the 50kW model. Maximum PV input current is 4 × 40A, with a maximum short-circuit current of 4 × 60A.

When designing a system, one should not regard the recommended maximum PV array capacity of 100kW and the maximum usable PV input of 96kW as a justification for setting up strings without carrying out electrical calculations. It is necessary for each string to stay within the inverter’s voltage and current limits after taking into account the solar module’s Voc, Vmp, Isc and Imp, the effects of temperature, and the string configuration that has been chosen.

It is especially important when using modern high-current solar modules, and the installer must compare the real electrical characteristics of the modules with the inverter’s per-MPPT and string limits before finalising the array.

Battery Compatibility and Energy Storage

The inverter uses a high-voltage Li-ion battery system with a battery operating voltage range of 150–800V. It provides two battery inputs, allowing the storage system to be configured around the inverter’s supported battery architecture.

The 50kW model has a maximum charge/discharge power of 55kW and a maximum charge/discharge current of 70A × 2; the maximum charge/discharge power for each battery input is 35kW.

Battery communication is supported through CAN and RS485, allowing communication between the inverter and compatible battery BMS systems.

Specific battery brands or models should be selected only after confirming voltage compatibility, BMS communication, protocol requirements, firmware compatibility and the manufacturer’s approved battery compatibility information. A battery should not be considered compatible based on voltage alone.

Backup Power and Load-Shedding Performance

In cases where power outages occur frequently, the backup feature is one of this model’s key advantages. The inverter has a rated backup output of 50kW at three-phase voltage.

The backup port has a switching time of less than 10 ms, which helps those loads switch quickly to battery-backup operation, and the inverter can also supply up to 1.6 times the rated backup power for a period of 2 seconds, provided that the actual system configuration and load characteristics allow it.

The inverter is capable of handling unbalanced and half-wave loads on both the grid and the backup ports, thus offering more flexibility in cases where the various phases do not have the same load.

The level of performance that can be achieved still relies on the battery’s capacity, its power output capability and the amount of load that is connected. The fact that an inverter has a 50kW rating does not mean that all possible battery setups are able to supply 50kW continuously.

Generator Support and Smart Load Control

This model does support the integration of a generator, with a maximum generator input power of 50kW. Also, the inverter has peak-shaving functions available in both self-use and generator modes.

It can be of use in the case of commercial sites which have to coordinate the use of solar power, battery storage, power from the grid and generator supply in accordance with the site’s operating requirements.

The generator and load arrangement must be designed in accordance with the electrical ratings of the generator and the input limits of the inverter.

Monitoring and Communication

The inverter has a 7-inch LCD display which shows information about the local system and also supports Bluetooth as well as an app for interacting with the system.

Communication interfaces include:

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

It is possible to monitor the battery in real time and to carry out remote upgrades. Such features enable installers and system operators to keep track of how the system is operating and to manage the various remote functions available without having to depend solely on the inverter’s local display.

Recommended Solar System Size

An important aspect to consider when designing this system is the difference between the inverter’s 50kW AC rated output and the PV capacity it allows.

The inverter has a rated AC output of 50kW, the recommended maximum size for the PV array is 100kW and the maximum usable PV input is 96kW. It therefore follows that the solar array can be considerably larger than the AC output rating of the inverter.

The greater PV capacity can assist in boosting solar power production during times when irradiance is below peak levels and will also supply more energy for charging the batteries. The final PV design however has to stay within the inverter’s maximum DC voltage of 1000V, its MPPT range of 150 to 850V, as well as the current and short-circuit current limits.

When determining string size it is necessary to take into account the module’s Voc, Vmp, Isc, Imp and the temperature correction rather than relying solely on the panel’s wattage.

Hybrid Inverter Use in Pakistan

A high-capacity hybrid inverter could be useful for commercial users in Pakistan when daytime solar consumption, battery storage and backup power are all to be operated together.

In the day the PV array can meet the site’s electricity demands while any surplus solar energy is fed into the connected battery system, and the energy thus stored can be used to supply certain loads when solar production decreases or when electricity from the grid is no longer available.

The fast backup switching—under 10 milliseconds—and the 50kW backup output are especially important for companies that need a quicker transition when important electrical loads are affected. When choosing the battery capacity one must still take into account the required backup duration and the actual load profile.

The fact that summer temperatures in Pakistan means that installation conditions are important; even though the inverter has a operating temperature range of -25°C to +60°C, adequate ventilation and appropriate mounting conditions are still necessary for reliable operation. The IP66 rating offers good protection against external influences, and its intelligent fan-cooling system looks after the heat generated during operation.

Installers must also use protection equipment for direct current and alternating current that is properly rated, together with the cabling, earthings and isolation devices as specified by the system design and the relevant electrical requirements.
