The SYN 50-XH-30 from Growatt is a back-up box that acts as an emergency backup power supply for the house and is able to provide up to 10kW from the solar storage system in the event of a power failure. The switchover time is 0.5 seconds. The Back-Up Box is characterized by a user-friendly design, which enables uncomplicated installation and operation.

The SYN Back-Up Box

• Backup power supply for the entire house, up to 10 kW
• 100% 3-phase asymmetrical output
• Integrated switch
• Easy to install
• Can be combined with the entire Growatt MOD-XH BP series

Compatibility

To achieve off-grid operation of a Growatt MOD-XH BP inverter, the SYN 50-XH-30 can be combined as an option. The following hybrid inverters are intended for this purpose:

• MOD 3KTL3-XH BP
• MOD 4KTL3-XH BP
• MOD 5KTL3-XH BP
• MOD 6KTL3-XH BP
• MOD 7KTL3-XH BP
• MOD 8KTL3-XH BP
• MOD 9KTL3-XH BP
• MOD 10KTL3-XH BP

The MOD-XH-BP series

• 2 independent MPPTs
• Battery-ready, future-proof
• Type II SPD on DC and AC side
• Integrated AFCI function
• Support for export limitation
• OLED and touch button
• DC/AC ratio up to 2.0
• Off-grid function possible with optional accessories

Hybrid inverter

In contrast to conventional inverters, hybrid inverters can not only feed the electricity generated by the solar system into the grid, but also store it in batteries. This means that the solar power is also available when the sun is not shining. Another feature of hybrid inverters is their ability to optimize a household's electricity consumption by preferring to use the solar power directly in the household before feeding it into the grid.

Active safety with AFCI function

An Arc Fault Circuit Interrupter is an arc fault protection device. It protects circuits in the event of arcing faults and acts as a circuit breaker against contact faults in low-voltage installations. In addition to providing protection, it analyzes current and voltage curves using digital signal processing and interrupts circuits in the event of fault signatures. Colloquially, the AFCI is also known as a fire protection switch, as overheating at poor contact points or flashovers between two conductors can be prevented by emitted signals.

The APX battery system

All the inverters mentioned above are compatible with the APX battery system. Thanks to the modular concept, the APX system can be used flexibly and expanded as required. A battery tower can be installed with a minimum of one and a maximum of six APX 5.0P-B1 battery modules. One power module per tower is required for operation, choosing between the APX 98020-P1 or the APX 98034-P2. The BMS must be purchased separately and an additional base is required for floor mounting.

Flexible expansion

The APX battery system from Growatt demonstrates its flexible configuration options. These can be expanded from 5kWh to 30kWh. The simple and modular design makes installation and expansion very straightforward with the help of cables. Another advantage of the new storage system is that, unlike other systems, a battery cabinet is no longer required. Only a battery base is required for a secure stand. The APX series supports the combination of mixed battery packs from new and old batches, as well as different capacities.
