Produktvorteile

-- 1.920 Wh AC storage: Retrofits an existing micro-inverter system on the AC side.

-- 800 VA mains / 1.200 VA off-grid: Clearly separates the permissible grid-connected power from the off-grid power function.

-- Up to 1.800 VA AC charging power: Enables rapid energy absorption within the enabled configuration.

-- Quiet operation below 17 dBA: Suitable for installation locations close to residential areas, provided the installation guidelines are followed.

Compatibility

AC-coupled retrofit solution for compatible 230V balcony power plants and household electrical systems. The battery operates independently of direct PV wiring and can be connected to compatible smart meters for demand-based control or zero feed-in. Two units can be connected using the separately available expansion kit to achieve a total capacity of 3,84 kWh. For larger multi-unit configurations, current firmware, phase, and function specifications from Hoymiles apply.

Why Mini Power

Mini Power disconnects at Hoymiles HiBattery 1920 The values ​​for grid operation, off-grid output, and AC charging are clearly defined. Capacity, efficiency, and expansion are also kept separate: one unit offers 1.920 Wh, two units 3,84 kWh with separate accessories. Information on smart meters, firmware, and phase planning shows which functions depend on the specific system configuration. This allows for a reliable comparison of the AC storage system with existing balcony power plants.

Frequently asked questions

-- What is the power output in grid and off-grid operation?

When connected to the grid, the HiBattery delivers up to 800 VA. Up to 1.200 VA is possible at the off-grid output, including a 10-second peak rating from the manufacturer.

-- Can the capacity be expanded?

Yes. Two HB-1920-AC units can be coupled together to achieve 3.840 Wh using the separately available connection and mounting kit.

-- Is the PV power connected directly to the battery?

No. The HiBattery is AC-coupled and is integrated into a suitable system on the AC side.
