Three‑Phase Hybrid Inverters Deye SUN-3/4/5/6K-SG05LP3-EU-SM2

The Deye three-phase hybrid inverters from the SUN-K-SG05LP3-EU-SM2 series are versatile, high-performance units designed for residential and small commercial photovoltaic systems. They offer power ratings from 3 kW to 6 kW, 100% unbalanced output on each phase, and support parallel operation of up to 10 units. With compatibility for low-voltage 48V batteries, AC coupling functionality, and support for energy storage from diesel generators, these inverters provide flexibility and reliability in energy management.

Key features of the Deye SUN-K-SG05LP3-EU-SM2 Hybrid Inverters:

• 100% unbalanced output: Ability to deliver up to 50% of the rated power on a single phase, which is crucial for uneven household loads.
• High scalability and parallel operation: Up to 10 units can be connected in parallel, both in on-grid and off-grid modes, with support for multiple batteries connected in parallel.
• Compatible with 48V batteries: Transformer-isolated design dedicated to working with common low-voltage 48V batteries (lead‑acid or lithium‑ion), with a maximum charge/discharge current of up to 135A.
• Advanced energy management: Configurable with 6 charge/discharge periods for batteries, AC coupling for upgrading existing solar systems, and support for storing energy from diesel generators.
• High efficiency and reliability: Peak efficiency up to 97.6%, MPPT efficiency >99%, and multiple integrated protections, including DC reverse polarity protection and AC/DC surge protection (Type II).
• Emergency power: In off-grid mode the inverter can supply twice the rated power for 10 seconds, enabling startup of demanding loads.

Who is this a good choice for?

The Deye hybrid inverters in this series are an excellent option for single-family homeowners and small businesses looking for a flexible, efficient, and reliable energy management solution. Their ability to handle unbalanced loads, expand the system, and work with popular low-voltage 48V batteries makes them ideal for maximizing self-consumption, providing backup power, and upgrading existing photovoltaic installations.
