Custom work by Off Grid Supply

Off Grid Supply can put together any desired package and fully tailor it to the customer's needs. Whether it concerns more or less storage capacity, a different inverter capacity, a 1-phase or 3-phase solution, additional emergency power functionality, or a configuration that better suits consumption and the available solar panel installation: we think along with you and put together a suitable system for every situation.

As a result, this package also provides a strong foundation for customers seeking a similar solution but with specific requirements regarding capacity, storage, expandability, or installation conditions. Together, we determine which configuration best suits the home, energy consumption, and the customer's future plans.

Why choose this Felicity package

The FLB48230WG1-H battery is a modern LiFePO4 home battery offering high safety, a long lifespan, and a robust IP65 housing. Each battery features built-in Wi-Fi and Bluetooth for monitoring, a smart battery management system, a fuse, an interrupter, and a built-in aerosol fire extinguishing system. Thanks to wall or floor mounting and optional automatic heating, this battery is versatile for use in a wide range of installations.

The IVGM20KLP3G1 hybrid inverter is a powerful three-phase solution for systems with high energy demand. This inverter supports on-grid, off-grid, and UPS operation, making it attractive to customers who, in addition to storage, desire greater flexibility in energy management and operational reliability. Thanks to 2 MPPTs, support for WiFi monitoring, and an IP65 protection rating, this is a suitable combination with the FLB battery series.

Combining four batteries creates a total storage capacity of 46.8 kWh. This makes this package particularly suitable for locations with higher consumption, large solar panel installations, or situations where more energy needs to be available in the evening, at night, or during peak periods.
