Deye 5kW SUN-5K-SG05LP3-EU-SM2 Hybrid LV 3 phase inverter

Deye SUN-5K-SG05LP3-EU-SM2 – 5 kW three-phase LV hybrid inverter

The Deye SUN-5K is a three-phase, low-voltage (48 V) hybrid inverter designed for residential and small commercial energy storage systems. The device can simultaneously manage solar power generation , the battery, and the grid connection, making it the foundation of a complete energy management solution.

What is it used for?

This inverter is the ideal choice for systems where the goal is to increase self-consumption and achieve energy independence. It works well in single-family homes, small businesses, or locations where backup power during outages is critical.

A particular advantage is that it can be integrated into existing solar panel systems (AC coupling), making it suitable for retrofitting energy storage.

How does it work?

The SUN-5K operates as a hybrid inverter: it directly uses the energy generated by the solar panels, stores it in the battery, or feeds it back into the grid.

The system can intelligently manage charging and discharging cycles, with up to 6 different timing periods per day. This allows you to optimize energy usage based on consumption and electricity rates.

The device also supports parallel operation by connecting up to 10 inverters, enabling the creation of larger systems.

Technical and system-level benefits

The inverter operates with 48 V batteries, which means simpler and safer installation for smaller systems. The high charging/discharging current of up to 240 A allows it to respond quickly to consumption demands.

It is capable of 100% asymmetric output, meaning it can efficiently handle different loads on each phase—which is particularly useful in residential settings.

It also supports generator charging, making it suitable for use in locations where a stable grid is not always available.

SOLARKIT Reviews

The SUN-5K is a versatile, flexible hybrid inverter that serves as an ideal entry point into the world of energy storage systems. Its key strengths include asymmetric operation and parallel scalability.

One of its biggest advantages is that it is suitable not only for new systems but also for expanding existing solar systems. This provides significant flexibility in many projects.

Overall, this is a stable, highly scalable inverter that is a good choice if you want to build a reliable LV hybrid system.
