Deye inverters and batteries: a guide to the range

The range at a glance

From homes to commercial sites

Residential storage

All-in-one or separate components?

Deye offers integrated systems as well as arrangements with a separate hybrid inverter and battery. An integrated stack brings the main equipment together; separate components give the system designer another way to arrange the equipment for the site.

AI-W5.1-B ESS

Deye lists 5.12kWh LiFePO4 battery modules for the AI-W5.1-B ESS. The range is designed for scalable residential storage, with single- and three-phase configurations. Battery capacity and inverter power are selected separately to suit how the property uses energy.

Energy management

Make better use of solar

A hybrid system can use solar generation, battery storage and grid power together. Its settings can be configured around the household’s usage, electricity tariff and desired battery reserve.

Deye also offers a wireless energy management system using LoRa communication. Compatible devices can help coordinate loads such as switches, meters and EV charging with the energy system.

• Solar use: direct more generation towards loads and battery charging.
• Time-of-use tariffs: plan battery charging and discharge around electricity rates.
• Smart loads: coordinate supported devices with available energy.

Power during an outage

Understanding backup

A hybrid inverter with a backup output can supply selected circuits when the grid fails. The amount it can run depends on the inverter’s backup rating, the battery and the loads connected to the backup circuit.

Deye has described 4ms switching for a specific all-in-one model. A backup design should be matched to the equipment it needs to support.

Commercial and industrial

BOS-G Pro battery storage

Deye’s BOS-G Pro range uses 5.12kWh LiFePO4 modules in high-voltage commercial battery configurations. Deye’s Australian solution brochure lists example systems from 25.6kWh to 81.92kWh.

These battery systems can be paired with suitable commercial hybrid inverters to support projects such as solar self-consumption and energy management.

Planning your system

What to consider before choosing

• Energy use: review your daytime and evening consumption and the solar generation available.
• Single- or three-phase: match the system to the property’s supply and proposed loads.
• Backup requirements: identify the circuits, motor starting loads and battery reserve you need.
• Battery capacity: choose storage to suit the energy you want to use later.
• Equipment and installation: check the selected models, compatibility, installation location and applicable Australian approval requirements.
