Solis 8KW L-PLUS Hybrid Inverter

Solis 8KW L-PLUS Hybrid Inverter Overview

The Solis 8 kW inverter S6-EH1P8K-L-PLUS is a single-phase low-voltage energy storage inverter for solar systems that need both daytime PV generation and battery-backed power during grid outages. The 8 kW model accepts a 40–60 V battery system and supports both Li-ion and lead-acid battery types according to the manufacturer’s datasheet.

For buyers researching the Solis 8 kW hybrid inverter, the L-PLUS model combines an 8 kW AC output with a comparatively large PV input capability. The manufacturer specifies a recommended maximum PV array size of 16 kW and a maximum usable PV input power of 12.8 kW. It uses two MPPTs and supports up to four PV input strings, with a maximum DC input voltage of 500 V.

The L-PLUS series is intended for use in demanding power situations, with the manufacturer stating that automatic switching to backup mode takes less than 4 ms, that it has a 200% overload capacity for 10 seconds, that it is compatible with generators and that it features two backup ports for managing both essential and non-essential loads. Moreover, several inverters can be operated together to create a microgrid.

This combination makes the Solis Hybrid 8 kW Plus particularly relevant where battery backup, high PV capacity and future system expansion are important considerations.

Why This Hybrid Inverter Stands Out

High PV Input Capacity

The 8 kW L-PLUS model has a recommended maximum PV array size of 16 kW, while its maximum usable PV input power is 12.8 kW. This gives system designers considerably more PV capacity than the inverter’s 8 kW AC rating alone might suggest.

For a buyer comparing the Solis 8 kW plus hybrid inverter, the important distinction is that the 8 kW figure refers to the inverter’s rated AC output. At the same time, the PV side has its own manufacturer-defined limits. The final solar array must remain within the inverter’s voltage, current and MPPT limits.

Two MPPTs with Four String Inputs

The inverter provides 2 MPPTs with up to 4 input strings. Its maximum PV input current is 32 A per input arrangement, while the maximum short-circuit current is 40 A per input arrangement.

For installers, the use of two MPPTs makes it easier to separate PV strings in those cases where different array orientations or operating conditions call for independent tracking. The specific arrangement of the strings has to be designed in accordance with the solar modules chosen and the inverter’s electrical limits.

190 A Battery Charge and Discharge Current

The 8 kW model supports up to 190 A maximum battery charge/discharge current and up to 8 kW maximum charge/discharge power.

For buyers who expect the battery system to have to supply heavy loads when the grid fails, this specification is important. It also implies that the battery should not be chosen on the basis of its voltage only, since the battery’s continuous current capability and the BMS communication requirements must be suitable for the system.

Fast Backup Switching

The manufacturer specifies a backup switch time of less than 4 ms. The datasheet also specifies 8 kW rated backup output and a maximum apparent backup output equal to twice the rated power for 10 seconds.

In practice, this is helpful in cases where it is necessary for important loads to switch rapidly from the grid supply to battery backup. The actual performance still varies according to the equipment connected, the installation and the operating conditions.

Generator and Parallel Operation

The L-PLUS series is compatible with generators, which enables the generator to increase the duration of backup power during a grid failure, and the manufacturer has also stated that several inverters can work together to form a microgrid.

These functions make the Solis inverter 8 kW Plus better suited to larger or more demanding installations than a basic battery inverter without generator or expansion capability.

Best For

The Solis 8KW L-PLUS is worth considering for:

• Homes that are larger and which have heavy daytime and backup loads.
• The properties which require battery backup when there is load shedding.
• Solar systems in which a relatively large photovoltaic array is planned alongside an 8 kW AC inverter.
• Users need a battery design based on low voltage.
• In cases where it is useful to integrate a generator in order to deal with prolonged outages.
• Sites which are commercial or semi-commercial may gain from the use of parallel inverter operation.
• Systems which have the need for separate control of the critical and non-critical backup loads.

Not Ideal For

Another inverter may be more appropriate when:

• The property does not have a single-phase output but requires a three-phase inverter.
• The battery system which is planned for use lies outside the stated 40 to 60 volt range.
• A small solar system doesn’t require an 8 kW inverter or a large amount of battery capacity.
• The project needs a battery, specifying the make and model, that has not yet been verified as being compatible.
• The photovoltaic array that is required goes beyond the manufacturer’s limits in voltage or current.
• The model does not have documentation relating to the functionality that is required by the installation.

Solar PV Input and MPPT Performance

The 8 kW L-PLUS has a maximum DC input voltage of 500 V, a rated PV voltage of 330 V, and a startup voltage of 90 V. Its MPPT operating range is 90–435 V. The model has two MPPTs and supports up to four PV input strings.

These specifications are the key reason buyers should check the Solis 8 kW hybrid inverter datasheet before finalizing a solar panel configuration.

The manufacturer specifies:

• Recommended maximum PV array size: 16 kW
• Maximum usable PV input power: 12.8 kW
• Maximum DC input voltage: 500 V
• Rated voltage: 330 V
• Startup voltage: 90 V
• MPPT voltage range: 90–435 V
• MPPTs: 2
• Maximum input strings: 4
• Maximum input current: 32 A / 32 A
• Maximum short-circuit current: 40 A / 40 A

When planning the actual PV array, the datasheet information for the Solis 8 kW Pluss should be referred to rather than depending solely on the inverter’s 8 kW AC rating.

When the installer is designing the solar array, the module’s Voc, Vmp and Isc figures, the number of modules in each string, the minimum and maximum operating temperatures, and the current limits of each MPPT all need to be checked beforehand.

A PV array with a capacity of 16 kW therefore cannot be connected if it includes a total of 16 kW of panels. The design having to stay within the inverter’s limits for DC voltage and current.

Battery Compatibility and Energy Storage

This is a low-voltage battery hybrid inverter with a specified battery voltage range of 40–60 V. The manufacturer lists both Li-ion and lead-acid battery types.

For the 8 kW model, the manufacturer specifies:

• Battery type: Li-ion / Lead-acid
• Battery voltage range: 40–60 V
• Maximum charge/discharge power: 8 kW
• Maximum charge/discharge current: 190 A
• BMS communication: CAN / RS485

In the case of a high-load backup system the 190 figure is especially important; the battery chosen must be able to provide the necessary current and have compatibility with the inverter’s BMS communication method.

Verified Compatible Battery Options

The supplied manufacturer datasheet confirms the battery types, voltage range and CAN/RS485 communication. Still, it does not provide a named list of compatible battery brands or models in the documentation reviewed.

Because of that, the names of particular battery brands should not be given as verified compatible options merely on the basis of this datasheet.

It is necessary to check, before buying, whether the battery is compatible with the inverter manufacturer’s list of supported batteries, its required voltage, the current capacity and the BMS communication protocol.

Backup Power and Load-Shedding Performance

One of the main reasons for considering the L-PLUS series for use in Pakistan is its backup capability.

The 8 kW model has an 8 kW rated backup output, with a maximum apparent backup output of 2× rated power for 10 seconds. The manufacturer gives a backup switching time of less than 4 ms. Backup output is specified at 220/230 V, single-phase L/N/PE.

The datasheet also shows that there are dual backup ports for the intelligent control of both critical and non-critical loads.

It can be of use in a house or a company when some of the equipment needs to be given priority during load shedding, while the less important loads can be looked after separately.

The inverter by itself does not give a fixed amount of backup hours; the actual length of time it provides backup mainly depends on the usable capacity of the battery, the amount of power connected to it, the state of charge of the battery, the efficiency of the inverter, and the battery’s operating limits.

Generator Support and Smart Load Control

The L-PLUS series is generator-compatible, and the manufacturer specifically describes generator compatibility as a way to extend backup duration during grid power outages.

For the 8 kW model, the generator input section specifies:

• Maximum generator input power: 8 kW
• Maximum generator input current: 36.4 A / 34.8 A
• Rated generator frequency: 50 Hz / 60 Hz

The datasheet that was provided shows that there are dual backup ports for the control of both critical and non-critical loads. Since the document under review gives no sufficient details regarding any smart-load functions other than those mentioned, it is necessary to check the relevant installation manual before specifying such features for the project.

For buyers looking for the Solis 8 kW plus hybrid inverter manual, the installation and operating details should be checked against the official manufacturer manual for the exact S6-EH1P8K-L-PLUS model.

Parallel Operation and System Expansion

The manufacturer states that multiple inverters can operate together to form a microgrid.

This provides the L-PLUS platform with an expansion path for installations where a single inverter may not be sufficient for the required system architecture.

The datasheet provided does not state the exact maximum number of parallel units or the number allowed for each supported phase configuration; it is therefore necessary to check the appropriate Solis installation documentation before designing a particular parallel system.

Monitoring and Communication

The inverter includes a 7.0-inch LCD, Bluetooth and app functionality. Communication interfaces listed by the manufacturer include RS485 and CAN, with Wi-Fi, GPRS and LAN available as optional communication features.

Such interfaces are useful when you want to view and manage the information relating to the inverter and the battery system; CAN and RS485 are especially important for communication with the battery BMS, while the optional connectivity hardware can offer extra monitoring capabilities.

The datasheet which has been provided does not include a full list of all the app monitoring screens or historical data functions, and therefore it cannot be assumed that the manufacturer has capabilities beyond those which are documented.

General Specifications

For technical buyers specifically looking for the Solis 8 kWW Plus inverter datasheet, these specifications provide the main electrical and general characteristics of the exact S6-EH1P8K-L-PLUS model reviewed.

The Solis 8 kW hybrid inverter datasheet PDF should always be checked for the latest manufacturer information before installation or system design.

Recommended Solar System Size

The manufacturer specifies a recommended maximum PV array size of 16 kW and a maximum usable PV input power of 12.8 kW for the Solis 8KW L-PLUS.

It must not be confused with the inverter’s 8 kW AC rating; the 8 kW figure refers to the rated output, whereas the individual DC input specifications are what determine the size of the PV array.

For a practical design, the installer should check:

• Solar panel wattage.
• Module Voc and Vmp.
• Module Isc.
• The number of panels in each string.
• MPPT voltage range.
• Maximum MPPT input current.
• Short-circuit current limits.
• The lowest temperatures in winter and the highest in summer.
• The objectives regarding roof space and the system’s operation.

The datasheet states that a maximum array size of 16 kW is recommended. However, the precise number and layout of the panels should be based on the electrical characteristics of the modules chosen rather than merely on the total panel wattage.

Hybrid Inverter Use in Pakistan

A hybrid inverter is especially useful for both houses and businesses in Pakistan when the solar power generated is to operate in conjunction with batteries and the grid rather than functioning as a basic daytime solar system.

The Solis 8KW L-PLUS is suitable for use in connection with load-shedding since it has a dedicated backup output of 8 kW and states that the transfer time is under 4 ms.

When planning a system, due attention must be paid to the low-voltage 40–60 V battery design. The battery bank should be chosen on the basis of the inverter’s voltage, current and communication requirements, not just by selecting one according to its nominal capacity.

In Punjab and in Lahore it is also necessary to take the installation conditions into account when it is hot. Even though the manufacturer gives a specified range of -40°C to +60°C for the ambient operating temperature and states an IP66 rating for the enclosure, the inverter must still be installed in accordance with the manufacturer’s installation requirements, with adequate ventilation and protection from inappropriate exposure to the environment.

In the case of systems that use a generator, the generator input capacity that is documented can serve as an extra way of extending the amount of available backup energy when there is a longer power outage.
