Short introduction

The Solis S6 15kW + 2 x Felicity 16kWh home battery is a complete three-phase energy storage installation for users who need more than a standard small home battery. With 32kWh of storage capacity, this set is suitable for homes with high electricity consumption, larger PV installations, heat pumps, EV chargers, electric boilers or other heavier loads.

The Solis S6 15kW hybrid inverter manages the energy flows between solar panels, the home, the grid connection and the batteries. The two Felicity batteries store energy and supply it later when the home needs power. With a properly configured backup power installation, selected circuits can continue operating during a grid outage.

Detailed system explanation

This combination consists of a three-phase Solis S6 hybrid inverter and two Felicity 16kWh battery modules. The inverter controls the energy flows in the installation. During the day, solar energy can be used directly in the home, stored in the batteries or exported when the batteries are full. In the evening or during higher loads, the system can use stored energy from the batteries.

The Solis S6 15kW low-voltage hybrid series is designed for large residential PV energy storage systems with 48V batteries. This makes the inverter suitable for low-voltage LiFePO4 batteries such as the Felicity FLB series, provided that exact compatibility, firmware and communication are configured correctly.

The two Felicity FLB48314TG1-H batteries provide a combined 32kWh of storage capacity. These batteries use LiFePO4 technology, operate at 51.2V nominal voltage and communicate via CAN/RS485. Thanks to IP65, integrated heating and aerosol fire suppression, the battery is designed for robust fixed energy storage installations.

How does this three-phase home battery with backup power work?

Which applications is this set suitable for?

This combination is especially suitable when a standard single-phase home battery is too limited. With 15kW inverter power and 32kWh battery capacity, the system is interesting for users with higher peak loads, more solar panels and a greater need for backup reserve.

• Larger homes with a three-phase connection.
• Households with many solar panels and high evening consumption.
• Homes with a heat pump, EV charger, air conditioning, electric boiler or high-load appliances.
• Customers who want to combine 32kWh battery capacity with backup power.
• Small commercial installations, workshops, farms and business premises.
• Situations where peak shaving or limiting peak grid consumption is desired.
• Installations where self-consumption of solar power is important.
• Users looking for a fixed, scalable installation instead of a plug & play battery.

Who is this Solis + Felicity combination suitable for?

This set is suitable for users who want a powerful three-phase home battery installation and who are not only focused on storage, but also on backup power, safety, expandability and future-proof energy management. The system is particularly interesting when the home or business premises has a higher than average energy consumption.

• Homeowners with a three-phase electrical panel and larger PV installation.
• Users who consume a lot of electricity in the evening or at night.
• Customers who want to reduce export and use more solar power themselves.
• Households preparing for reduced net metering benefits and changing energy tariffs.
• Businesses that want to use a battery for storage, backup or peak shaving.
• Customers who want backup power for selected circuits or essential equipment.
• Users who value LiFePO4, IP65, heating and additional fire safety.

Key technical features

Compatibility, expansion and system limits

This combination is built around a three-phase Solis S6 15kW hybrid inverter and two 51.2V Felicity LiFePO4 batteries. The batteries communicate with the inverter via CAN/RS485. For reliable operation, the correct battery settings, firmware, cabling, protection and communication parameters must be applied.

The battery capacity may be technically interesting to expand later, but expansion always depends on the chosen battery model, inverter configuration, available space, cabling, fuses and desired output. Additional capacity increases storage duration, but does not automatically increase the maximum AC power of the inverter.

Backup power: what can you expect?

This set can be configured with a backup power function. This means selected circuits can continue operating when the electricity grid fails. In practice, it is determined in advance which appliances are important and which loads fit within the system capacity.

• Suitable for lighting, internet, refrigerator, freezer and basic comfort.
• May be suitable for heat pump control, central heating, office equipment or security systems, depending on power demand.
• 32kWh battery capacity provides a generous buffer for essential circuits.
• Backup duration depends on current state of charge, connected circuits and actual consumption.
• Large appliances must be assessed to prevent overload.
• During installation, the electrical panel, phase distribution and desired backup circuits are assessed.

Peak shaving and smart energy use

In addition to storing solar power, a battery can help limit peaks in grid consumption. This is especially interesting for homes or businesses where high power is needed for short periods, for example due to EV chargers, heat pumps, machinery or other simultaneous loads.

The exact possibilities for peak shaving, dynamic tariffs and energy control depend on the selected metering setup, Solis settings, energy meter, smart meter, possible P1 connection and external EMS software. Off Grid Supply can advise which configuration fits the desired use.

What is included in this installation package?

The exact installation can differ per situation, because the electrical panel, solar panels, cable routes, existing inverter, main fuse and desired backup circuits are not the same everywhere. The basis of this set consists of the Solis 15kW hybrid inverter, two Felicity 16kWh batteries and professional installation by Off Grid Supply.
