1.92 kWh 940W HiBattery HB-1920 Storage System with Double-Glass Solar Modules, including Hoymiles HMS-800-2WB Single-Phase Inverter

With the Offgridtec balcony power plant (MPN: 025098), you can generate your own solar power and store excess energy for later use. Depending on the model you choose, the kit consists of two or four Trina Solar Vertex S+ double-glass solar modules, each with a power output of 470 Wp, a matching Hoymiles microinverter, and one or two Hoymiles HiBattery HB-1920-AC-SV AC storage units, each with a capacity of 1,920 Wh.

This means the complete set offers a PV module output of 940 or 1,880 Wp and a storage capacity of 1.92 or 3.84 kWh. The Hoymiles storage unit supports the on-demand use of self-generated solar energy. In self-consumption mode, stored electricity can be made available to the household at a later time. The Time-of-Use (TOU) mode also enables time-dependent charging and discharging control, for example, to take advantage of suitable electricity rates.

The combination of bifacial double-glass solar modules, a matching microinverter, and an AC storage system offers a flexible solution for self-sufficiency. The HiBattery uses passive cooling and features integrated protection functions.

Important installation note: The version with the Hoymiles HMS-1600-4T has a rated output of 1600VA. The installation and grid connection of this model must be performed by a qualified electrician. For the 800VA version as well, the applicable connection and registration requirements, as well as the manufacturer’s instructions, must be followed.

Your benefits of the complete set

• Generate your own solar power: With 940 or 1,880 Wp of PV module power, you can cover part of your electricity needs yourself.
• Store solar power: One or two Hoymiles HiBattery storage units offer a total storage capacity of 1.92 or 3.84 kWh.
• Increase self-consumption: Stored energy can be used even when the solar modules are generating little or no electricity.
• Flexible system selection: The combination of the number of modules, microinverters, and storage capacity can be tailored to your needs.
• Smart operating modes: Self-consumption mode and time-of-use control support energy usage tailored to your needs.
• Quiet storage operation: The Hoymiles HiBattery uses fanless cooling via natural convection.

The set includes

• 2 or 4 Trina Solar 470W Vertex S+ double-glass N-type i-TOPCon solar modules (depending on the variant)
• 1x or 2x Hoymiles HiBattery HB-1920-AC-SV AC storage unit with 1920Wh LiFePO4 (depending on the variant)
• 1x Hoymiles microinverter compatible with the selected PV module configuration:
  • Hoymiles HMS-800-2WB HiFlow 800 Pro for the 940Wp variant
  • Hoymiles HMS-1600-4T for the 1880 Wp variant
• 2x MC4-to-MC4 connection cables, 6 mm², 1 m, red/black
• If necessary, 2x MC4-to-MC4 connection cables, 6 mm², 3 m, red/black (depending on the variant)
• Mounting kit according to the selected variant

Notes on expanding the system with additional batteries

Depending on the variant, the set includes one or two Hoymiles HiBattery storage units. If you expand the system later, you must follow the manufacturer’s connection specifications:

• A maximum of two batteries can be stacked to form a tower.
• A third battery must be connected to a separate phase of the electrical system.
• A maximum of two batteries is allowed per phase. With three-phase distribution, this allows for up to six batteries in three stacks of two, provided the system requirements are met.
• If three or more batteries are used, the off-grid port for the microinverter is deactivated. The microinverter must then be connected directly to the home electrical system.
• For Hoymile microinverters without integrated Wi-Fi, a compatible DTU-Lite-S or DTU-Pro-S is required for data transmission.
