LV three-phase hybrid inverters
Three-phase Deye hybrid inverters with LV batteries. Ideal for family homes and smaller businesses.
Buying guide
Deye three-phase hybrid inverters for 48 V low-voltage batteries are the most common choice for family houses and small businesses. The range includes 8, 10, 12, 15 and 20 kW models — from a typical family house to smaller commercial sites with higher consumption.
How to choose the power
The SUN-8K, SUN-10K and SUN-12K models (SG05LP3 series) accept a PV array of up to twice the rated power — for example, a 10 kW inverter takes up to 20 kWp of panels. When appliances start up, they can deliver twice the rated power for 10 seconds.
The SUN-15K and SUN-20K models (SM2 series) are intended for larger houses and businesses. They have a higher battery charge and discharge current — 280 A for 15 kW and 350 A for 20 kW — and handle fully unbalanced phase loads.
For demanding conditions and larger systems
All models have an IP65 rating and an operating range of -40 to +60 °C, so they can also be installed outside heated spaces. Two MPPT trackers allow panels on two sides of the roof to be connected.
For higher power, the inverters can be connected in parallel — up to 10 units according to the datasheet. RS485, RS232, CAN, WiFi and Bluetooth communication, efficiency of 97.6–98.0% depending on the model, 10-year warranty.
Batteries for LV inverters
Deye three-phase LV inverters are designed for use with 48 V LiFePO4 batteries: Deye SE-F5 Pro-C (5.12 kWh), SE-F12-C (11.8 kWh) and SE-F16-C (16 kWh). Choose the capacity according to how much energy you need for the evening and night.
Frequently asked questions
What inverter power does a family house need?
It depends on the PV array power and the highest simultaneous load. For a typical family house, 8–12 kW models are the most common choice; for larger houses and businesses, 15–20 kW. We will be glad to help you with the configuration.
How many panels can I connect to the inverter?
The 8, 10 and 12 kW models accept a PV array of up to 16, 20 and 24 kWp. The exact string voltage and current limits are in the datasheet on the product page.
What does the SM2 designation on the 15 and 20 kW models mean?
It is a newer series of Deye three-phase LV inverters with a higher battery charge and discharge current (up to 280 A and 350 A respectively) and support for fully unbalanced phase loads.
Can the inverters be connected in parallel?
Yes, up to 10 units according to the datasheet. Parallel connection is used in larger buildings where one inverter is not enough.
