What is the Deye collection?

The Deye collection brings together equipment for photovoltaic energy: grid-tied inverters, hybrid inverters (single-phase and three-phase) with backup functions, as well as LiFePO4 lithium batteries and communication accessories and racks. Its offering combines high efficiency, IP65, multiple MPPT, AC/DC coupling options, and parallel scalability.

Advantages and limitations

• Performance: benchmark efficiencies, wide MPPT range, and features such as anti-PID and zero export management.
• Resilience: fast EPS/backup, parallel operation, and diesel generator support in hybrid models.
• Integration: CAN/RS485 communications with 48 V and HV batteries; LAN/Wi-Fi monitoring via portal.
• Protection: IP65 enclosures, insulation, and transformer options in three-phase models.
• Limitations: choose correctly between 48 V vs HV according to the inverter; check charge/discharge current limits and maximum number of units in parallel.

Applications

• Residential: single-phase hybrid inverters with 48 V (LV) battery for self-consumption with backup.
• Light commercial: three-phase hybrid solutions with high voltage (HV) banks and unbalanced power per phase.
• Industrial: high-power three-phase grid-tied inverters with multiple MPPT and advanced management.

How to choose

• Inverter type: grid-tied if there is no battery; single-phase hybrid or three-phase hybrid if storage/backup is required.
• Battery voltage: 48 V for maximum compatibility and retrofit; HV for higher efficiency and power in three-phase systems.
• MPPT and power: size by string (Voc/Imp) and peaks; prioritize models with 2–6 MPPT depending on the complexity of the PV array.
• Parallel/EPS: confirm number of units and backup power for critical loads.

Best practices

• Calculate strings by temperature (max Voc) and MPPT window; balance by MPPT when there are different orientations.
• Define EPS power and autonomy: select 48 V or HV battery according to loads and inverter type.
• Install suitable DC protections and AC protections (SPD, disconnectors, fuses).
• Plan parallel connection and rack space reservation for future expansions.

Comparisons and related routes

• Single-phase grid-tied inverters and three-phase (without battery).
• 48 V (LV) batteries and HV batteries compatible.
• Battery accessories and inverter accessories for integration and monitoring.

Related accessories

• 19” racks for HV clusters and BOS-G-PDU control boxes.
• LAN/Wi-Fi stick logger and communication cabling.
• DC/AC protections and disconnectors for regulatory compliance.

Deye offers a complete platform of inverters and storage that combines efficiency, robustness, and advanced integration, ideal for maximizing self-consumption with battery or for high-performance grid connection projects.
