Deye 15kW Three-Phase Hybrid Inverter SG05LP3-EU-SM2 | 48V Low Voltage Solar Inverter
Product Description
The Deye 15kW Three-Phase Hybrid Inverter SG05LP3-EU-SM2 is a powerful 48V low-voltage hybrid inverter designed for larger residential, commercial, agricultural, and light industrial solar systems. With three-phase output, high PV input capacity, strong battery charging and discharging capability, and advanced energy management features, this inverter is ideal for customers who need a reliable solar and backup power solution.
This model supports 100% unbalanced output, with a maximum output of up to 50% rated power per phase, making it practical for sites where loads are not evenly spread across all three phases. It can also be used to retrofit existing solar systems through AC coupling, making it a flexible option for upgrading older installations.
The Deye 15kW three-phase inverter supports up to 10 units in parallel for both on-grid and off-grid operation, while also allowing multiple batteries to be connected in parallel. With support for lithium-ion and lead-acid batteries, a 48V low-voltage battery design, and self-adaptive BMS communication for lithium batteries, it offers a smart and expandable power solution.
This inverter also features 6 programmable time periods for battery charging and discharging, giving users better control over energy usage, grid charging, solar storage, and backup power. It can also support storing energy from a diesel generator, making it suitable for demanding backup and off-grid applications.

Still figuring out how the battery usage is managed, but as for the rest it operates seamless.
Got the app operational with a little help from my friend and gives useful information. Enjoying the Deye 12kW journey.
Still need to neaten-up the wiring though.
I thank you.
Overall, this inverter has exceeded my expectations. Highly recommended to anyone
