Deye SUN-3.6K-SG05LP1-EU-AM2 - 3.6 kW low-voltage hybrid inverter

The Deye SUN-3.6K-SG05LP1-EU-AM2 is a compact, single-phase hybrid inverter that has been specially developed for smaller photovoltaic systems in residential buildings. With an AC output power of 3.6 kW it offers the ideal introduction to energy independence by combining solar power generation, battery management and emergency power supply in a single device.

As part of the SG05 series this inverter is designed for operation with 48V low-voltage batteries optimised. This makes the system particularly flexible and cost-effective when selecting a storage solution. Despite its compact design, it features all the ‘major’ Deye features, such as the Smart Load connection and parallel scalability.

Highlights at a glance

• Low-voltage battery connection: Compatible with standard 48V lithium-ion and lead-acid batteries, offering a wide range of cost-effective storage options.
• Colour touchscreen LCD: Intuitive operation and real-time monitoring of all energy flows directly on the device via the integrated display.
• 2 MPPT trackers: Enables the connection of two independent strings of modules, ideal for roofs with different orientations (e.g. east-west).
• Excellent backup function: Lightning-fast switchover to emergency power in less than 10 ms, ensuring that sensitive equipment continues to operate without interruption in the event of a mains power failure.
• AC coupling possible: Existing solar installations can be easily integrated via the inverter to retrofit them with a storage system.
• Parallel connection: Up to 16 units can be connected in parallel to flexibly increase system performance as demand rises.
• Smart load connection: The ‘Smart Load’ port enables targeted control of loads such as heating elements or pool pumps when there is a surplus of solar energy.

Areas of application

The SUN-3.6K is the specialist for efficient small-scale systems:

• Detached houses & flats
  • Perfect for PV systems up to approx. 4.6 kWp, to drastically increase self-consumption in the home.
• Retrofitting
  • Add a 48V battery storage system to an existing installation without having to replace the old inverter.
• Critical infrastructure
  • Protection for servers, aquariums or heating controls thanks to the reliable UPS function.

Installation & Safety Instructions

• Battery protection
  • As high currents can flow in 48V systems, it is essential to ensure that the cable cross-sections are sufficiently large and that a suitable DC fuse is fitted between the battery and the inverter.
• Wall mounting
  • The unit is robustly built and designed for wall mounting. Thanks to its IP65 protection rating, it can also be installed in a sheltered outdoor area.
• Earthing & lightning protection
  • Ensure that the system is properly earthed to protect the electronics and connected loads from power surges..

FAQs on the Deye SUN-3.6K-SG05LP1

Which batteries are compatible with this inverter?

Suitable for almost all 48V lithium storage systems.

• It is perfectly compatible with popular models such as Pylontech (US2000C/US3000C/US5000), Dyness or Deye ’s own low-voltage batteries. Conventional lead-gel batteries can also be configured. It is essential to check the batteries against the compatibility list before purchasing.

Can I use the inverter for a balcony power plant?

Technically yes, but oversized.

• While it far exceeds the output of a balcony power plant, it offers the advantage that you can integrate a proper battery and later expand the system into a full roof-mounted installation.

Is the Wi-Fi module for app control included?

Generally speaking, yes.

• Deye It usually comes with a Wi-Fi dongle, which you can use to connect the system to the ‘Solarman’ app or the Deye portal to view energy yields and consumption worldwide.

Can the unit start a generator?

Yes.

• Via the signal port, the inverter can send an automatic start command to compatible generators if the battery level is too low and there is no sunlight.
