The Growatt SYN 100-XH-30 is a reliable backup solution for your home, ensuring an uninterrupted power supply in the event of a power outage. This innovative box can deliver an impressive 40 kW from the solar storage system and offers a very fast switchover time of just 0.5 seconds. It is compatible with the Growatt MID-XH and MOD-XH BP inverter series. Furthermore, it stands out for its user-friendly design, which ensures effortless installation and use

The SYN Back-Up Box

  • Backup power supply for the entire home, up to 40 kW
  • 100% 3-phase asymmetric output
  • Integrated switch
  • Easy to install
  • Compatible with the entire Growatt MID-XH and MOD-XH BP series

Compatibility

To enable off-grid operation of a Growatt MID-XH or MOD-XH-BP inverter, the SYN 100-XH-30 can be optionally combined. The following hybrid inverters are designed for this purpose:

  • MID 11KTL3-XH
  • MID 12KTL3-XH
  • MID 13KTL3-XH
  • MID 15KTL3-XH
  • MID 17KTL3-XH
  • MID 20KTL3-XH
  • MID 25KTL3-XH
  • MID 30KTL3-XH
  • MOD 4KTL3-XH BP
  • MOD 6KTL3-XH BP
  • MOD 7KTL3-XH BP
  • MOD 8KTL3-XH BP
  • MOD 9KTL3-XH BP
  • MOD 10KTL3-XH BP

The MID-XH Series:

  • 2 independent MPPTs
  • Battery-ready, future-proof
  • Type II SPD on DC and AC sides
  • Integrated AFCI function
  • OLED, LED, and touch button
  • DC/AC ratio up to 2.0
  • 24-hour self-consumption monitoring

The MOD-XH BP Series:

  • 2 independent MPPTs
  • Battery-ready, future-proof
  • Type II SPD on DC and AC sides
  • Integrated AFCI function
  • Export limitation support
  • OLED, LED, and touch buttons
  • DC/AC ratio up to 2.0

The APX Battery System

All of the inverters listed above are compatible with the APX battery system. Thanks to its modular design, the APX system is flexible and can be expanded as needed. A battery tower can be constructed with a minimum of one and a maximum of six APX 5.0P-B1 battery modules. One power module is required per tower for operation. You can choose 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 here. These are scalable from 5 kWh up to 30 kWh. Thanks to the simple and modular design, installation and expansion are very straightforward using 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 needed to ensure stability. The APX series supports the combination of mixed battery packs from new and old batches, as well as different capacities.
