Deye 8K-SG05LP3 + ESS-DEYE-SE-F12-C

What does the package include?

The Deye SG05LP3 hybrid inverter + ESS-DEYE-SE-F12-C energy storage package is a complete, three-phase, low-voltage (48V) hybrid solution that combines an inverter and LiFePO4 energy storage in one system. The package is designed for hybrid operation (on-grid / off-grid / UPS), supports energy storage, timed charging and discharging, and generator input as required. The functions of the hybrid inverters and the range of models in the series are listed in the manufacturer's documentation.

What inverter capacities are available with the package?

The ESS-DEYE-SE-F12-C energy storage system is available with the following SG05LP3 three-phase hybrid inverters:

5 kW – SUN-5K-SG05LP3-EU-SM2
6 kW – SUN-6K-SG05LP3-EU-SM2
8 kW – SUN-8K-SG05LP3-EU-SM2
10 kW – SUN-10K-SG05LP3-EU-SM2
12 kW – SUN-12K-SG05LP3-EU-SM2

This allows the system's performance to be adjusted to the consumption of the property in question, the planned PV size, and three-phase loads.

What should you know about the ESS-DEYE-SE-F12-C energy storage system?

The ESS-DEYE-SE-F12-C is an energy storage system based on LiFePO4 (LFP) technology, providing a nominal energy storage capacity of 11.8 kWh at a nominal voltage of 51.2 V (230 Ah). The system is specified at 90% DoD and its design allows for modular expandability: multiple units can be connected in parallel to create a larger storage capacity if the project requires it. Communication is based on CAN2.0/RS485, and Bluetooth + app interface is also included in the specifications.

What can the SG05LP3 hybrid inverter series do in practice?

The SG05LP3 series of three-phase hybrid inverters are designed for residential and small commercial systems, with 48V battery operation and wide mode support. The series supports timed battery charging/discharging settings (with 6 time slots), generator energy storage, AC coupling solutions for expanding existing solar systems, and three-phase, asymmetric output operation.

Who is this package recommended for?

This package is a good choice for three-phase properties where the goal is to increase self-consumption, reduce grid consumption, and cover part of the consumption from the battery during appropriate times of day. It may be particularly relevant for higher evening consumption, heat pumps, electric car charging, or energy use where timed charging/discharging and backup options offer a real advantage.

Why is it advantageous to be able to choose from several inverter outputs?

The fact that the same energy storage package is available with 5/6/8/10/12 kW inverters means that, in practice, there is no need to compromise: a smaller inverter can be chosen for properties with lower consumption, while a higher-power version can be chosen for higher loads and PV sizes. This helps to ensure that the system is not undersized (with too much grid support), but also not unnecessarily oversized.
