Short introduction

The Felicity 5kW inverter + 16kWh home battery is a complete energy storage solution for a single-phase home. Solar energy generated during the day can be stored in the battery and used later when the sun is not shining. This increases solar self-consumption and reduces dependence on direct export to the grid.

What makes this combination especially interesting is the backup power function. With the correct configuration, selected circuits or important appliances can continue operating when the electricity grid fails. Examples include lighting, internet, refrigerator, freezer, central heating system, heat pump control or other essential devices.

Detailed system explanation

This Felicity set consists of two main components: the hybrid inverter and the home battery. The inverter is the control centre of the system. It manages energy flows between the solar panels, the home, the grid connection and the battery. The battery stores energy and releases it later when the home needs power.

The Felicity IVGM5KLP1G1 is a single-phase hybrid inverter with a nominal output power of 5kW. The inverter is suitable for a 48V/51.2V low-voltage battery system and has 2 MPPT trackers for solar panels. This allows flexible PV design, for example with two roof surfaces or two string orientations.

The Felicity FLB48314TG1-H battery offers 16kWh storage capacity at 51.2V and uses lithium iron phosphate technology. This battery is equipped with a smart BMS, breaker, fuse, CAN/RS485 communication, IP65 housing, heating and an integrated aerosol fire suppression system. This makes the package suitable for users who want a safe, complete and serious home battery solution.

How does the Felicity home battery with backup power work?

Which applications is this set suitable for?

This Felicity combination is particularly suitable for homes with a single-phase connection or a single-phase sub-installation where 5kW inverter power is sufficient. The 16kWh battery capacity is generous for many household applications and provides a practical buffer for daily self-consumption and backup reserve.

• Homes with solar panels that want to use more of their own solar energy.
• Households that want to be less dependent on exporting electricity to the grid.
• Homes where backup power for essential circuits is desired.
• Situations with evening consumption, heat pump control, refrigerator, freezer, internet and lighting.
• Users who want a fixed installation instead of a loose plug-in battery.
• Homes with a technical room, garage, utility room or other suitable installation location.
• Customers looking for a complete package including installation and configuration.
• Energy storage for smart self-consumption, comfort and additional security.

Who is this Felicity combination suitable for?

This set is suitable for users who want an affordable but serious home battery installation. The system is interesting when you are not only looking at payback time, but also at energy security, comfort during power outages, preparation for changing net metering rules and higher self-consumption of solar energy.

• Homeowners with solar panels and a single-phase home installation.
• Customers who want a large battery capacity without a complex three-phase system.
• Households that consider a backup power function important.
• Users looking for a system including installation.
• Homeowners who want to prepare for less favourable export and net metering conditions.
• Customers who value LiFePO4, IP65, heating and additional fire safety.
• Users who may want to expand later within the technical limits of the installation.

Key technical features

Compatibility, expansion and system limits

The Felicity 16kWh battery is technically scalable and supports parallel expansion. In this combination, however, the 5kW single-phase inverter determines the maximum AC power the system can supply to the home. Additional battery capacity can be useful for longer autonomy, but it does not automatically increase the maximum inverter output.

For larger homes, three-phase connections, heavy heat pumps, saunas, high-load appliances or full three-phase backup, a different system configuration may be more suitable. Off Grid Supply can assess whether this single-phase Felicity set is sufficient or whether a three-phase solution is a better fit.

Practical advantages in daily use

A home battery becomes most valuable when it matches the real energy profile of the home. Charging during the day with solar energy, discharging in the evening for household consumption and keeping a reserve for backup power makes this Felicity set practical for many homes.

• More self-consumption of generated solar energy.
• Less dependence on export compensation and net metering rules.
• Ability to keep important appliances running during grid failure.
• Large 16kWh battery capacity for daily use and backup reserve.
• 5kW inverter power for many standard household applications.
• Suitable for smart control via inverter settings and optional energy management.
• Robust battery with IP65, heating and additional fire safety provision.
• One complete package instead of loose components without coordination.

What is included in this installation package?

The exact installation may differ per home, because the electrical panel, solar panels, cable routes and desired backup circuits vary from one situation to another. The basis of the package consists of the Felicity hybrid inverter, the 16kWh battery and professional installation by Off Grid Supply.

• Felicity IVGM5KLP1G1 5kW single-phase hybrid inverter.
• Felicity FLB48314TG1-H 16kWh LiFePO4 home battery.
• Battery with IP65, heating and built-in aerosol fire suppression.
• Connection and configuration of inverter and battery.
• Setup of backup power for selected circuits, depending on the home.
• Functional check and basic explanation upon completion.
• Installation according to relevant professional installation guidelines.

Backup power: what can you expect?

Backup power does not automatically mean that every appliance in the home can run indefinitely. In a well-designed system, selected circuits are usually connected to the backup output. This keeps battery power available for the appliances that really matter.

• Suitable for lighting, internet, refrigerator, freezer and basic comfort.
• May be suitable for central heating, heat pump control or other essential equipment, depending on power demand.
• Heavy loads such as electric cooktops, saunas, large boilers or heavy machinery must be assessed separately.
• Backup duration depends on battery capacity, current state of charge and consumption.
• By choosing the right backup circuits, the installation remains efficient and reliable.
