Short introduction

The Felicity FLB48230WG1-H is designed for users who want to get more out of their solar panels, increase their self-consumption and choose a scalable battery storage solution for the coming years. With 11.7 kWh gross storage capacity, this battery is larger than many standard 5 kWh modules, while still remaining compact and suitable for wall or floor mounting.

This battery is not a standalone plug-in battery, but a professional low-voltage battery module for use with a compatible hybrid inverter or energy storage system. In combination with the correct inverter, the battery can help store solar energy, reduce grid consumption, support backup power functions and build larger installations for homes, farms, workshops and small commercial applications.

Detailed product explanation

The Felicity FLB48230WG1-H is part of the FLB series of low-voltage LiFePO4 batteries. The battery is designed for energy storage in residential and light commercial systems. In practice, this type of battery is used to temporarily store solar energy and use it later, for example in the evening, during higher electricity prices or when solar production is low.

The nominal voltage of 51.2V makes the battery suitable for 48V/51.2V low-voltage systems. This is a commonly used voltage class for hybrid inverters in homes and smaller businesses. Through CAN and RS485 communication, the battery can exchange data with a suitable inverter, such as state of charge, temperature, protection status and charge or discharge limits.

An important advantage of this battery is the combination of capacity, safety and scalability. A single module already provides 11.7 kWh of storage capacity. Users who need more storage later can have multiple batteries connected in parallel. This allows the system to grow with a larger PV installation, higher electricity consumption, an electric vehicle, heat pump or a commercial application with peak loads.

How does the Felicity FLB48230WG1-H work?

Which applications is this battery suitable for?

The FLB48230WG1-H is especially interesting in situations where a standard small home battery is too limited, but where a large industrial battery container system is not required. Thanks to the high capacity per module and the option to connect up to 32 modules in parallel, the system can be used in a wide range of applications.

• Homes with solar panels that want to use more of their own solar energy.
• Households preparing for the end of net metering in the Netherlands from 2027.
• Homes with a heat pump, EV charger, air conditioning or high evening consumption.
• Small businesses that want to store energy or reduce peak loads.
• Farms, workshops and garages with single-phase or three-phase energy storage through a suitable inverter.
• Off-grid and semi-off-grid installations with solar panels and a hybrid inverter.
• Backup systems where essential circuits need to remain powered during grid outages.
• Projects where IP65 protection, monitoring and additional fire safety are important.

Who is the Felicity FLB48230WG1-H suitable for?

This battery is suitable for users who want to build a professional energy storage system and are not looking for a simple plug & play plug-in battery. The FLB48230WG1-H belongs in a fixed installation with a suitable hybrid inverter, correct protection devices, appropriate cabling and correct configuration of the communication between battery and inverter.

• Private homeowners with high electricity consumption and solar panels.
• Homeowners who want to feed less power back to the grid and use more themselves.
• Customers who want an expandable system that can grow later.
• Users who consider backup power important, provided the inverter and installation support this.
• Installers looking for a 51.2V LiFePO4 battery with CAN/RS485 communication.
• Small commercial users looking for a robust battery solution for energy storage and peak shaving.

Key technical features

Compatibility and expandability

The Felicity FLB48230WG1-H is a 51.2V low-voltage battery and must be combined with a compatible hybrid inverter or battery inverter that supports the battery protocol. Communication takes place via CAN or RS485. In practice, it is therefore important to look not only at voltage, but also at firmware, BMS communication, charge/discharge limits and the correct inverter settings.

Off Grid Supply can apply this battery in tailor-made solutions with suitable low-voltage inverters. This includes single-phase systems for homes, three-phase systems for larger grid connections and expandable installations where several Felicity modules are installed in parallel.

• Suitable for 48V/51.2V low-voltage systems.
• Communication via CAN or RS485.
• Parallel expandable up to 32 batteries.
• Suitable for hybrid systems with solar panels and grid connection.
• Suitable for backup power when the selected inverter supports EPS/backup functionality.
• Not intended as a standalone 230V power source without an inverter.

Practical advantages in daily use

A home battery only becomes truly valuable when it properly matches the consumption profile, solar panels, grid connection and inverter. The FLB48230WG1-H provides a solid foundation for this. The relatively high 11.7 kWh capacity makes it possible to use a large share of the solar energy generated during the day at a later time.

• More self-consumption of generated solar power.
• Reduced dependence on feeding power back to the electricity grid.
• Better preparation for the end of the Dutch net metering scheme from 2027.
• Possibility to use energy smartly with dynamic tariffs, depending on inverter and EMS.
• More comfort during power outages when installed with backup power functionality.
• Expandable for growing electricity demand, for example due to a heat pump or electric vehicle.
• Suitable for installations where safety, monitoring and robust placement are important.

Backup power, peak shaving and smart energy use

The Felicity FLB48230WG1-H can be used as part of a backup power system, but only when the rest of the installation is suitable for this. The battery supplies low-voltage DC power. For use in a home, a suitable inverter is always required to provide 230V or three-phase AC power and to support a backup or EPS function.

For peak shaving, a battery can help temporarily cover peak consumption. This is especially interesting for small commercial installations, homes with high simultaneous loads or situations where upgrading the grid connection is expensive or difficult to realise. The exact operation depends on the selected inverter, measuring setup, energy meter and settings.

For smart charging, dynamic tariffs or energy management, an external EMS function or smart inverter logic is usually required. The battery itself is the storage module; control of charging, discharging, grid consumption and possible tariff-based operation is determined by the inverter and connected energy management software.
