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 one device.

As part of the SG05 series this inverter is optimised for operation with 48V low-voltage batteries. This makes the system particularly flexible and cost-efficient when selecting storage. Despite its compact design, it features all the "big" Deye features such as the smart load connection and parallel scalability.

Highlights at a glance

• Low-voltage battery connection: Compatible with common 48V lithium-ion and lead-acid batteries, offering a wide range of affordable storage options.
• Colour touch LCD: Intuitive operation and real-time monitoring of all energy flows directly at the unit via the integrated display.
• 2 MPPT trackers: Enables the connection of two independent module strings, ideal for roofs with different orientations (e.g. east-west).
• Excellent backup function: Lightning-fast switch to emergency power in less than 10 ms, so that sensitive devices continue to run without interruption in the event of a power failure.
• AC coupling possible: Existing solar installations can easily be 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 increases.
• Smart load connection: The "Smart Load" port enables targeted control of consumers such as heating rods 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 massively increase self-consumption within the household.
• Retrofitting
  • You can add a 48V battery storage system to an existing system without having to replace the old inverter.
• Critical infrastructure
  • Securing servers, aquariums or heating controls through reliable UPS function.

Installation & safety instructions

• Battery protection
  • As high currents can flow in 48V systems, please ensure appropriately dimensioned cable cross-sections and a suitable DC fuse between the battery and inverter.
• Wall mounting
  • The device is robustly built and designed for wall mounting. Thanks to IP65 protection, installation in protected outdoor areas is also possible.
• Earthing & lightning protection
  • Ensure that the system is installed with professional earthing to protect the electronics and connected appliances from surges.

Properties

FAQs about the Deye SUN-3.6K-SG05LP1

Which batteries are suitable for this inverter?

Almost all 48V lithium storage units.

• It works perfectly with common models such as Pylontech (US2000C/US3000C/US5000), Dyness or Deye's own low-voltage batteries. Conventional lead gel batteries can also be configured.

Can I use the inverter for a balcony power plant?

Technically yes, but it is 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 to a full rooftop installation.

Is the WLAN module for app control included?

Usually, yes.

• Deye usually supplies a Wifi dongle, which allows you to connect the system with the "Solarman" app or Deye's own portal to view yields and consumption worldwide.

Can the device start a generator?

Yes.

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