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 installations. They offer power ratings from 3 kW to 6 kW, 100% unbalanced output on each phase, and the ability to operate in parallel with up to 10 units. Compatible with low-voltage 48V batteries, featuring AC-couple functionality and support for storing energy from a diesel generator, 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 rated power on a single phase, which is important 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.
• Compatibility with 48V batteries: Transformer-isolated design intended for use with common low-voltage 48V batteries (lead-acid or lithium-ion), with maximum charge/discharge current up to 135A.
• Advanced energy management: Ability to set 6 battery charge/discharge periods, AC-couple feature for upgrading existing solar systems, and support for storing energy from a diesel generator.
• High efficiency and reliability: Maximum efficiency up to 97.6%, MPPT efficiency >99%, and numerous 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 its rated power for 10 seconds, enabling the start-up of 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 seeking a flexible, efficient, and reliable energy management solution. Their ability to handle unbalanced loads, expand the system, and work with common low-voltage 48V batteries makes them ideal for maximizing self-consumption, providing backup power, and upgrading existing photovoltaic installations.
