3.84 kWh 1880W HiBattery HB-1920 Storage System with double-glazed solar modules, including Hoymiles HMS-1600-2T single-phase inverter

With the Offgridtec balcony power plant (MPN: 025098), you can easily generate and store your own solar power. The storage system includes either 2 or 4 high-performance 470 W double-glazed solar modules, a perfectly matched microinverter, and 1 to 2 LiFePO4 AC batteries, each with a capacity of 1.92 kWh. The intelligent system controller automatically determines when electricity should be stored or fed into the home’s electrical grid. Thanks to bidirectional charging and discharging cycles and the self-consumption mode, you can use as much of your self-generated electricity as possible right on-site. The AI-based TOU (Time-of-Use) mode further optimizes usage by adapting to electricity rates and typical consumption times. The combination of plug-and-play operation, quiet and maintenance-free technology, temperature tolerance, and comprehensive safety features ensures maximum suitability for everyday use. All relevant safety features are integrated at the factory and do not need to be retrofitted. The storage unit can easily be taken with you and reused if you move. Note: When using the HMS-1600-4T, you’ll need a licensed electrician to install the system.

Your benefits of the complete set

• Independence from electricity providers: You generate a large portion of your own electricity and are less affected by rising electricity prices
• Environmental protection: Solar energy is clean and sustainable, which significantly reduces your carbon footprint
• Self-consumption: With a storage system, you can use the electricity you generate even at night or during bad weather.
• Increased property value: A solar system with storage makes your home more attractive to potential buyers
• Reliability of supply: During power outages, you can continue to rely on stored solar power (depending on the system)

The set includes:

• Trina Solar 470W Vertex S+ double-glass N-type TopCon solar module (selectable as 2x or 4x)
• Hoymiles HiBattery HB-1920-AC-SV AC Storage 1920Wh LiFePO4 (select 1 or 2)
• 1x Microinverter compatible with the system
  • Hoymiles HMS-800-2WB HiFlow 800 Pro Microinverter
  • Hoymiles HMS-1600-4T Microinverter Module-Level Inverter
• 2x MC4-to-MC4 connection cables, 6 mm², 1 m, red/black
• MC4 to MC4 connection cable, 6 mm², 3 m, red/black (2x depending on selection)
• Installation kit

Important note for systems with more than 2 batteries:

• A maximum of 2 batteries can be stacked
• A third battery must be connected to a second house phase
• A maximum of 2 batteries is possible per phase, for a total of up to 3 stacks of 2 batteries each, or 6 batteries
• If there are 3 or more batteries, the off-grid port for the microinverter is deactivated. The inverter must then be connected directly to the home electrical system
• For Hoymile inverters without built-in Wi-Fi, a compatible DTU-Lite-S or DTU-Pro-S is also required

Vertex S+ 470W Solar Module

The Vertex S+ from Trina Solar is a high-performance 470W double-glass solar module that is ideally suited for both residential and commercial applications. Thanks to modern technologies such as high-density cell interconnection, the spacing between the solar cells is minimized, allowing more sunlight to be harnessed. Multi-busbar and N-type i-TOPCon technology further ensure higher light output, lower energy losses, and better current conduction.
