Fronius Symo Hybrid 3kVa Three-phase inverter
LG RESU Batteries 7kW 400V

The battery is charged during the day thanks to the production of photovoltaic panels.
It is discharged during the day when production is lower than consumption and at night in order to limit energy discharges into the distribution network to the strict minimum.
This system is suitable for a household with a consumption of approximately 6300 kW/year.

Consume your solar production when you need it 


There is an asymmetry between our electricity needs and the production of our solar system.
As can be seen in the graph below, the Ohybrid nduleur allows, via batteries, the storage of unused production during the day (on yellow lined).
So you enjoy the energy produced throughout the day in the morning and evening (red highlighted line)

Fronius Symo Hybrid 3 to 5 KVA Three phase



Fronius Symo Hybrid 3 to 5 KVA Three phaseThe Fronius Symo Hybrid allows you to temporarily store excess energy in a battery. This is THE solution for 24 hours of sunshine a day, even in the event of a power outage.
5-year guaranteed product
Possibility of warranty extension to 10, 15 or 20 years

Open-protocol data transmission

It's easy to connect components from third-party suppliers to Fronius inverters. The standard open Modbus TCP SunSpec protocol is a simple way to connect data to other systems. The protocol is used through the existing Ethernet interface, ensuring reliable communication.

Smart Grid Ready

Fronius inverters are ready for tomorrow's Smart Grid. The inverters are optimally equipped to meet future technical requirements. A series of smart features, called Advanced Network Features, are integrated into devices. These are a number of control functions for optimal injection of reactive and active power. These functions are designed for a stable network even when the density of the PV system is very high and prevent unwanted cuts with associated performance losses. Fronius inverters therefore help to ensure the performance of PV systems.

Fronius Smart 63A-3 Intelligent Energy Meter



Fronius Smart 63A-3 Intelligent Energy MeterThe Fronius smart meter is a two-way meter that optimizes self-consumption and records the household load curve. Thanks to very precise measurements and rapid communication via the Modbus RTU interface, dynamic power control when power limits are imposed is faster and more accurate than with the S0. With Fronius Solar.web, the Fronius smart meter provides a clear overview of electricity consumption in the home.
