The manufacturer’s newer 21A variants also have version-specific documentation.

For professional procurement, the exact suffix and technical revision must be checked rather than relying on the generic designation “Solis S6 hybrid inverter”.

Official manufacturer reference: Solis S6-EH1P(3–10)K-L-PLUS – Technical Specifications, Manuals & Certificates

Solis Low-Voltage Hybrid Inverter – Battery Current & Power Requirements

One of the most important technical characteristics of the Solis S6-EH1P-L-PLUS range is its 40–60V battery operating voltage.

This architecture is designed for compatible 48V-class and 51.2V nominal battery systems.

Unlike a high-voltage solar inverter, a low-voltage hybrid inverter must carry substantially higher DC current when charging or discharging at higher power levels.

Solis S6 Battery Charge & Discharge Current Comparison

The current product specifications listed by 3Buy Solar identify the following maximum inverter-side battery current ratings.

These are inverter-side maximum ratings, not guaranteed continuous currents from any connected battery. Final values must be confirmed against the applicable manufacturer documentation and the permitted operating conditions.

Why This Matters for Installers

A 10kW Solis hybrid inverter connected to a 51.2V battery requires substantial DC current to deliver high discharge power.

A battery advertised as 10kWh does not automatically have the capability to provide 10kW continuously.

The actual discharge power depends on the battery’s BMS current limit, operating voltage, temperature, state of charge and the inverter’s permitted operating limits.

For example, a 51.2V battery system limited to 100A provides approximately 5.12kW of DC power at nominal voltage before conversion losses.

This is why professional solar installers should calculate battery discharge power independently from battery energy capacity.

Battery Cabling & Protection

High-current low-voltage installations require particular attention to:

• DC cable conductor sizing
• Permitted voltage drop
• Battery terminal and connector ratings
• DC fuses and circuit breakers
• Battery isolation devices
• Maximum prospective fault current
• BMS charge/discharge limits
• Parallel battery current sharing
• Communication wiring
• Installation temperature

Correct battery integration is essential for safe operation and the expected performance of the hybrid inverter.

Solis Battery Compatibility 2026 – BYD, Dyness, Pylontech, Felicity Solar & More

Solis is particularly relevant to professional energy storage installers because it supports a broad range of manufacturer-validated third-party solar batteries.

Alongside its own SolisStorage ecosystem, Solis maintains battery matching documentation covering multiple battery manufacturers and inverter generations.

This gives installers additional sourcing flexibility when designing complete solar battery systems.

Solis Low-Voltage Battery Compatibility

The manufacturer’s global compatibility documentation includes selected low-voltage battery systems from brands such as:

• BYD
• Dyness
• Pylontech
• Felicity Solar
• Pytes
• WECO
• GSL Energy
• Fox ESS
• Soluna
• Puredrive
• Sunwoda
• UZ Energy
• LG Energy Solution

The wider compatibility documentation includes additional battery brands and model families.

Important: Brand Compatibility Does Not Mean Model Compatibility

Not every battery from these manufacturers is approved for every Solis hybrid inverter.

An approved combination requires matching the exact:

• Solis inverter model
• Battery model and generation
• Battery nominal and operating voltage
• BMS communication protocol
• CAN or RS485 interface
• Communication cable pinout
• Inverter firmware
• Battery firmware
• Permitted battery module configuration
• Maximum charging and discharging power

A battery being 48V, 51.2V, LiFePO4 or CAN-enabled does not, by itself, establish compatibility.

Solis Battery Compatibility Guide – 3Buy Solar Technical Resource

We have published a detailed guide specifically for European professional installers:

Solis Inverter & Battery Compatibility Guide 2026: Which Batteries Work with Solis Hybrid Inverters?

The guide covers:

Official Solis Battery Compatibility Documentation

The manufacturer maintains its own regularly updated battery matching documentation.

Solis – Official Battery Compatibility & Matching Guidance

Where a product is not included in the applicable matching document, compatibility should be confirmed through Solis technical support before ordering or commissioning.

Which Solis Hybrid Inverter Is Right for Your Project?

Solis manufactures multiple inverter families with different phase configurations, battery voltage classes and intended applications.

Important Model Naming Consideration

Solis model suffixes such as L, H, LV, NV, ND, K2 and 21A should not be interpreted without consulting the exact datasheet.

In some three-phase product families, a designation containing LV can refer to the AC grid voltage arrangement rather than identifying a conventional 48V battery input.

The manufacturer’s actual battery operating voltage range—not the product name alone—determines whether a low-voltage or high-voltage battery can be connected.

This is especially important when comparing Solis equipment intended for different European grid configurations.

Solis Three-Phase Hybrid Inverters – Residential & Commercial Energy Storage

Solis also manufactures high-voltage and low-voltage three-phase hybrid inverter platforms for larger photovoltaic installations.

These products extend the manufacturer’s portfolio beyond the single-phase S6 models currently listed at 3Buy Solar.

Solis S6-EH3P(3–12)K-H – Three-Phase High-Voltage Inverters

The Solis S6-EH3P(3–12)K-H is a three-phase high-voltage hybrid inverter platform.

Depending on the exact model, the series includes:

• Multiple MPPT configurations
• High-voltage battery integration
• Supported unbalanced phase output
• Intelligent battery management
• Generator integration
• Supported inverter parallel operation
• Backup power functionality
• SolisCloud monitoring

The platform is relevant to three-phase residential installations where the selected battery voltage, required AC output and photovoltaic array configuration are compatible.

Solis S6-EH3P(12–20)K-H – Higher-Power Residential Storage

The Solis S6-EH3P(12–20)K-H Series is designed for larger residential and smaller commercial solar PV energy storage systems.

The manufacturer’s current documentation covers power classes within this family, with 15kW and 20kW models highlighted in the current global portfolio.

Features include:

• Multiple independent MPPT trackers
• High-voltage battery integration
• Supported asymmetric three-phase operation
• Generator-compatible operating modes
• AC coupling possibilities
• Backup functionality
• Smart energy management
• Supported parallel installations

Asymmetric Three-Phase Power Output

In residential and commercial buildings, electrical loads are rarely distributed evenly across all three phases.

An inverter with supported asymmetric output can allocate power according to phase-specific demand within its operating limits.

However, an inverter’s total rated power does not automatically indicate the maximum output available on a single phase.

Installers must verify the manufacturer’s permitted phase imbalance and per-phase output limits, particularly when designing backup circuits.

Solis Low-Voltage Three-Phase Hybrid Inverters

Solis also provides three-phase hybrid platforms designed for compatible low-voltage battery systems.

These are relevant to installers who want to retain 48V-class energy storage while using a three-phase electrical connection.

The exact product family must be selected carefully, since the battery voltage architecture differs from Solis three-phase high-voltage hybrid models.

For current model variants, technical documentation and installation requirements, consult the Solis Official Hybrid Inverter Portfolio.

Solis Commercial Hybrid Inverters – 29.9kW to 60kW

For commercial and industrial photovoltaic installations, Solis manufactures high-power three-phase hybrid inverters with dedicated high-voltage battery interfaces.

The S6-EH3P(29.9–50)K-H and newer S6-EH3P(29.9–60)K-H(21A) platforms provide different power classes and technical configurations.

Solis S6-EH3P(29.9–50)K-H

The manufacturer’s 29.9–50kW platform includes models in the 29.9kW, 30kW, 40kW and 50kW classes.

Key technical features include:

• Four independent MPPT trackers
• Up to 20A PV string input current
• Two independently controlled high-voltage battery ports
• Maximum battery current of 70A + 70A
• Support for on-grid and off-grid operation
• Peak shaving functionality
• Generator integration
• Supported parallel inverter operation
• Backup overload capability under defined conditions
• Remote monitoring and energy management

These capabilities are relevant for warehouses, agricultural facilities, commercial buildings, workshops and industrial installations with significant daytime consumption.

Solis S6-EH3P(29.9–60)K-H(21A)

The newer Solis S6-EH3P(29.9–60)K-H(21A) expands the commercial hybrid range.

The manufacturer specifies:

• Power classes up to 60kW
• Four MPPT trackers
• Up to 21A input current per PV string
• Two independent battery inputs
• Up to 84A + 84A battery current on the 60kW model
• Supported parallel operation of up to ten units
• AC and DC coupling options
• Commercial peak shaving and smart energy management

These figures apply to the specified 21A product generation and must not be transferred automatically to earlier S6-EH3P(29.9–50)K-H equipment.

Why Battery Port Architecture Matters

For a commercial energy storage installation, the number of battery ports and available charge/discharge current can be as important as the inverter’s nominal AC output.

A 50kW commercial inverter with two battery inputs may provide significantly different battery integration options from a residential inverter with a single battery connection.

However, two battery inputs do not mean that any two high-voltage battery systems can be connected.

The permitted battery type, operating voltage, BMS configuration and parallel architecture must follow the current Solis compatibility documentation.

Commercial Applications

Solis C&I hybrid inverter systems are relevant for:

• Commercial solar self-consumption
• Peak shaving
• Time-of-use load shifting

Solis AC-Coupled Battery Inverters – Retrofit Existing Solar PV Systems

A battery retrofit does not always require replacing the existing grid-connected photovoltaic inverter.

Solis offers AC-coupled energy storage inverter platforms designed for suitable retrofit applications.

What Is an AC-Coupled Battery System?

In an AC-coupled installation, the existing solar PV inverter remains connected to the building’s AC electrical system.

A separate battery inverter charges and discharges the compatible energy storage system.

This architecture can be useful when:

• The existing PV inverter remains functional
• The customer wants to add solar battery storage
• Replacing the entire PV inverter is unnecessary or undesirable
• The electrical installation supports AC-coupled integration
• The metering and battery management architecture can be correctly configured

Solis AC-Coupled Inverter Platforms

The manufacturer’s portfolio includes:

• S6-EA1P low-voltage single-phase AC-coupled inverters
• S6-EA3P high-voltage three-phase AC-coupled inverters
• Related retrofit-oriented energy storage configurations

What Must Installers Check?

Before specifying an AC-coupled Solis battery retrofit, verify:

• Existing photovoltaic inverter model
• Grid connection and export limitations
• Compatible battery system
• AC connection point
• Required metering and CT placement
• Battery inverter power
• Communication interfaces
• Backup topology
• Existing system warranties
• Network operator approval requirements

A battery retrofit should be designed around the actual electrical installation, not merely the available roof PV capacity.

Explore Energy Storage Kits with Inverters for related system components.

Important Procurement Distinction

The SolisStorage residential and commercial battery platforms are not interchangeable with ordinary third-party battery modules.

Each system has its own approved power conversion, battery management and communication architecture.

Likewise, a battery that appears on the compatibility list for a Solis S6 low-voltage hybrid inverter should not be assumed compatible with a commercial EverCore system or another SolisStorage product.

3Buy Solar can assist with project-based enquiries for these product families, subject to availability.

Solis Backup Power, Generator Integration & Off-Grid Operation

Selected Solis hybrid inverters support backup operation when the public electricity grid becomes unavailable.

The correct backup architecture depends on the inverter model, selected battery, electrical distribution system and intended protected loads.

Backup Power with Solis S6-L-PLUS

The S6-EH1P-L-PLUS family provides dedicated backup functionality with manufacturer-specified switching below 10ms under supported conditions.

Selected models can provide short-duration overload power for loads with high starting current.

However, a fast switching specification does not mean every installation operates as a whole-house UPS.

Essential Loads vs Whole-Home Backup

An essential-load backup system supplies designated circuits, such as:

• Lighting
• Refrigeration
• Internet and telecommunications
• Selected pumps
• Security systems
• Other approved critical loads

A whole-home backup arrangement requires sufficient inverter output, battery power and appropriately engineered switching and electrical distribution.

Generator Integration

Solis also offers generator integration on selected hybrid inverter platforms.

This can be relevant for rural properties, weak-grid locations and installations requiring extended backup duration.

Generator compatibility depends on the specific inverter model, electrical connection arrangement, supported frequency and voltage limits, and control configuration.

Parallel Inverter Operation

Selected Solis S6 hybrid platforms are designed to support parallel operation.

However, the permitted number of units, firmware, meter arrangement and backup configuration must be confirmed for the actual installed inverter generation.

An advertised maximum parallel quantity should not be treated as approval for every hardware version or application.

Official technical reference: Solis Hybrid Inverter Commissioning & Parallel Operation Guidance

Solis Smart Energy Management – Heat Pumps, Solar Surplus & Time-of-Use

One of the developments in modern hybrid inverter technology is the integration of controllable electrical loads into the energy management strategy.

Solis offers functions for coordinating battery charging, solar generation and compatible connected equipment.

Solar PV Surplus & SG-Ready Heat Pumps

Selected Solis hybrid inverters support SG-Ready heat pump control through appropriate control interfaces.

The manufacturer has published a technical guide covering supported S6 inverter models, including relevant low-voltage and three-phase hybrid families.

Compatible configurations can use photovoltaic surplus and battery state-of-charge information to activate supported heat pump operating modes.

For example, the system can signal a compatible heat pump to increase useful heating when surplus PV generation is available.

This can help convert surplus electrical energy into stored thermal energy, such as domestic hot water.

Technical Requirements

Installers should verify:

• Supported Solis inverter model
• Current inverter firmware
• Heat pump SG-Ready interface
• Correct control terminal wiring
• Appropriate relay and contact configuration
• Selected energy management operating mode
• Battery reserve and charging strategy

Solis provides the inverter-side control interface; heat pump connection and commissioning must follow the heat pump manufacturer’s requirements.

Solis Official Guide – Using the Heat Pump Function on Solis Hybrid Inverters

Solis Complete Solar Kits – Inverter, Battery, PV Modules & Installation Equipment

A professionally engineered Solis solar battery installation requires the correct combination of inverter, battery and balance-of-system equipment.

A typical residential solar-plus-storage installation may include:

• Solis S6 hybrid inverter
• Compatible low-voltage or high-voltage solar battery
• Solar PV modules
• Manufacturer-approved battery communication cable
• Smart meter and current transformers
• AC and DC protective devices
• Battery DC isolation and fuses
• Appropriate PV mounting system
• Correctly rated DC and AC cables
• Solar monitoring communication equipment
• Backup switching and distribution equipment where required

Example – Solis 5kW Hybrid Inverter + 10kWh Solar Battery

A common residential system requirement is a 5kW hybrid inverter combined with approximately 10kWh of battery storage.

For a Solis low-voltage installation, the equipment selection begins with the S6-EH1P5K-L-PLUS and an approved 40–60V battery system.

The 10kWh battery capacity describes nominal energy storage, not necessarily usable energy or instantaneous discharge capability.

The battery must have sufficient BMS current rating to deliver the required charge/discharge power, and the correct Solis communication protocol must be supported.

The final bill of materials must also include the required metering, protective devices, battery cabling and optional backup equipment.

Example – Solis 10kW Hybrid Inverter + Larger Low-Voltage Battery

For an 8kW or 10kW single-phase installation, battery current requirements become substantially more important.

The inverter may support high discharge power, but the connected battery system must be capable of delivering it.

Installers should therefore specify the required battery power and usable capacity separately.
