Deye has established itself as a major player in the energy storage sector, known for manufacturing high-efficiency, durable, and technologically advanced inverters. From residential off-grid systems to large-scale commercial installations, Deye offers a versatile range of products designed to optimize energy consumption. A key factor in maximizing the performance of any Deye system is pairing it with the right lithium battery. This article provides an overview of Deye inverter technology and a detailed list of compatible lithium batteries, focusing on the popular 48V low-voltage systems.

Key Inverter Series

Off-Grid Inverters (e.g., OG Series)
Deye has recently released new off-grid inverter series such as the OG02. These units are designed for applications where grid independence is key. They feature an ultra-fast 4 ms switchover time from grid to battery power, ensuring that sensitive loads like computers and motors do not experience interruptions. These inverters typically offer PV input capacities ranging from 6 kW to 12 kW with an MPPT voltage range of 150 V to 425 V.

Hybrid Inverters (e.g., SUN Series)
The SUN series hybrid inverters are the most versatile, capable of managing solar panels, battery storage, and the grid simultaneously. Key models include:
SUN-(5-12)K-SG04LP3 Series: These are three-phase hybrid inverters suitable for residential and light commercial use. They feature a battery voltage range of 40-60V, support a maximum charging/discharging current of up to 250A, and are compatible with both lead-acid and lithium batteries. They boast a max efficiency of 97.6%.
SUN-20K-SG05LP3: This is a groundbreaking 20kW low-voltage three-phase hybrid inverter. It is the first in its class to utilize SiC (Silicon Carbide) components, which enhance efficiency and reduce the unit’s size. It supports a massive 350A charging and discharging current, making it ideal for high-power demand scenarios.

String Inverters (e.g., SUN-(120-136)K-G01P3)
For large commercial or industrial applications without battery storage needs, Deye offers high-power string inverters like the SUN-(120-136)K-G01P3 series. These units achieve a maximum efficiency of up to 98.6% and feature 2 MPP trackers to optimize energy harvest from different roof orientations.

Compatible Lithium Batteries
Deye inverters are designed to work seamlessly with a variety of lithium batteries, particularly those utilizing Lithium Iron Phosphate (LiFePO4) chemistry due to its safety and long cycle life. Communication between the inverter and the battery’s Battery Management System (BMS) is handled via protocols like CAN or RS485 for optimal performance.

How to Ensure Compatibility
When selecting a battery for your Deye inverter, consider the following factors:
Voltage Range: Most Deye hybrid and off-grid inverters operate on a 48V battery system (voltage range typically 40-60V). Ensure your battery bank matches this.
Communication Protocol: For the inverter to accurately read the battery’s State of Charge (SoC) and temperature, they must communicate via the same protocol.
Charging/Discharging Current: Match the battery’s maximum charge/discharge current with the inverter’s capability. For example, the high-power SUN-20K-SG05LP3 inverter requires a battery capable of handling 350A, which would necessitate a robust battery bank or multiple units in parallel.

By pairing a Deye inverter with a compatible lithium battery, users can achieve a highly efficient, reliable, and scalable energy storage system that maximizes solar self-consumption and provides backup power during grid outages.
