Deye SUN-8K-SG05LP1-EU-AM2-P single-phase hybrid inverter 8 kW

The Deye SUN-8K-SG05LP1-EU-AM2-P is a high-performance, single-phase hybrid inverter, specially developed to meet the requirements of modern households with high energy consumption. With an impressive rated output power of 8 kW it ranks amongst the most powerful single-phase units in its class and enables comprehensive optimisation of self-consumption as well as an uninterrupted emergency power supply.

The "P" series is intended for use with High-current PV modules optimised. Thanks to an increased input current of up to 26 A per MPPT, state-of-the-art solar panels with large cell formats and high yields can be efficiently integrated. As a low-voltage hybrid, the device operates with 48 V batteries combined, which allows for flexible and cost-effective scaling of the storage system.

Highlights at a glance

• Impressive 8 kW single-phase power: Ideal for households with high loads that require a high-capacity single-phase fuse or a high charging capacity for batteries.
• High-current PV inputs (26 A): Perfectly tailored to the latest generation of high-performance modules to maximise solar yields.
• 48 V low-voltage system: Fully compatible with a wide range of affordable and modularly expandable 48 V battery storage systems (e.g. LiFePO4 from Deye or Pylontech).
• High charging/discharging current (190 A): Enables rapid charging of large storage capacities and the powering of energy-intensive devices directly from the battery.
• Genuine emergency power output (UPS): Switches to stand-alone mode in less than 4 ms in the event of a mains failure, ensuring that even sensitive electronic equipment is protected without interruption.
• 2 MPPT trackers: Offers flexibility in roof layout and optimises yield for different orientations or partial shading.
• Smart Load & AC Coupling: Surplus energy can be specifically used to power appliances such as heat pumps; furthermore, existing inverters can be easily integrated.

Areas of application

• Large detached houses
  • Maximising self-sufficiency by combining high PV output with large, cost-effective 48 V storage systems.
• Backup & stand-alone solutions
  • Thanks to its high output of 8 kW, it is ideally suited for off-grid systems or for providing full backup during critical periods in regions with an unstable grid.
• Retrofit
  • Can be installed in parallel with existing solar systems via AC coupling to enhance them with a high-performance storage function.

Installation & Safety Instructions

• Battery wiring
  • Due to the 48 V technology and currents of up to 190 A, large cable cross-sections (e.g. 2 x 50 mm² or 70 mm²) and high-quality DC fuses are absolutely essential.
• Ventilation
  • The unit is equipped with active fan cooling. Install the inverter in a cool, well-ventilated location and observe the prescribed minimum clearances.
• Phase balancing
  • When operating on a three-phase mains supply (e.g. in Germany), a smart meter is required at the mains connection point to mathematically balance the consumption across all phases (net metering).

FAQs for the Deye SUN-8K-SG05LP1-EU-AM2-P

Can I operate a heat pump with this device?

Yes, no problem. Thanks to the high output power of 8 kW and the Smart Load function, the inverter can be configured to prioritise supplying the heat pump with surplus solar energy.

Is it possible to operate the device without a battery?

Yes, the device starts up even without memory. The inverter can be used as a standalone PV inverter. A 48 V storage system can be added at any time later via plug-and-play to increase self-consumption.

Does the device support zero-feed-in?
