Fronius GEN24 Plus with BYD Battery-Box Premium HVS/HVM  

The BYD Battery-Box Premium HVS/HVM is the successor of the BYD Battery Box HV. The BYD Box Premium Line is compatible with GEN24 Plus (HVS/HVM) and Symo Hybrid (HVM). The capacities of the batteries range from 5.1–12.8 kWh (HVS) and 8.3-22.1 kWh (HVM). Fronius has once again achieved true grid back-up, with the BYD Battery-Box Premium HVS/HVM. This means that even three-phase loads can be used in a grid back-up situation.   

Please note:

/ During commissioning, make sure to set up the BYD using the BeConnect App first, then afterwards commission the GEN24 Plus.

/ The BYD battery should always be turned on before the inverter.

Turning the system off:

1. Battery OFF: Hold the power button on the front at least 5 seconds.
2. Inverter OFF:  Switch off the DC-side (rotary switch on the inverter) and the AC-side (circuit breaker).
3. Leave the components off for at least 30 seconds. The LEDs of the inverter and battery must be completely off.

Turning the system on:

1. Battery ON: Switch on the battery fuses. If you're unable to switch on the fuses, hold the power button for 5 seconds and try again.

2. Inverter ON: Switch on the DC-side (rotary switch on the inverter) and the AC-side (circuit breaker).

Further information on this storage solution and its backup feature can be found in the Fronius GEN24 Plus Product Guide.

Fronius GEN24 Plus with LG FLEX

With the Fronius GEN24 Plus hybrid inverter and the high-voltage battery from LG Energy Solution, your customers can bring 24 hours of sunshine into their homes. This way, they have their generated PV energy reliably available at night and even in the event of a power outage. The combination of Fronius GEN24 Plus and LG FLEX enables high charging and discharging capacities for optimal use of solar energy from their own PV system. This not only allows for higher self-consumption but also sustainably ensures more autonomy and independence from the public power grid. The LG FLEX is clearly visualised in Fronius Solar.web. This way, you have all the data at a glance at any time – conveniently with just one click in a single app.

The LG FLEX battery impresses with the following strengths:

• Lithium battery storage (NMC), modularly expandable in 4.3 kWh steps
• Storage capacities of 8.6 kWh, 12.9 kWh, and 17.2 kWh*
• Emergency power capability (with PV Point and Full Backup)
• Various floor and wall mounting options available
• Temperature, water, and dust-resistant housing (IP 55 protection class)
  
  * depending on the type of inverter, country-specific certification, and availability

Fronius GEN24 Plus battery management

With battery management (time-of-use), rules can be defined according to which the battery is to be charged or discharged - depending on the day of the week and the time of day.

The advantages of this function:

• Individual definition of weekday and time of day dependent rules.
• Possibility for electricity tariff-dependent battery charging from the grid
• Reservation of storage capacity for the times with high PV production
