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 and efficient devices designed for residential and small commercial photovoltaic systems. They offer power ratings from 3 kW to 6 kW, 100% unbalanced output capability on each phase, and support parallel operation of up to 10 units. With compatibility with low-voltage 48V batteries, an AC-coupling feature, and the ability to store energy from a diesel generator, these inverters provide flexibility and reliability in energy management.

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

• 100% unbalanced output: Ability to deliver up to 50% of rated power on a single phase, which is important for uneven household loads.
• High scalability and parallel operation: Ability to connect up to 10 units in parallel, both in on-grid and off-grid modes, and support for multiple batteries connected in parallel.
• Compatibility with 48V batteries: Transformer-isolated design intended for use with common low-voltage 48V batteries (lead-acid or lithium-ion), with a maximum charge/discharge current up to 135A.
• Advanced energy management: Ability to set 6 battery charging/discharging periods, AC-coupling for upgrading existing solar systems, and support for storing energy from a diesel generator.
• High efficiency and reliability: Peak efficiency up to 97.6%, MPPT efficiency >99%, and numerous integrated protections, including DC reverse polarity protection and AC/DC surge protection (Type II).
• Backup power: In off-grid mode the inverter can deliver twice the rated power for 10 seconds to start demanding appliances.

Who is this a good choice for?

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