List of products by brand Deye

Deye is a Chinese manufacturer specialising in photovoltaic hybrid solutions and energy storage systems (ESS). Its products include hybrid inverters and modular LFP batteries, offering efficiencies of up to 97.6%, a lifespan of over 6,000 cycles and intelligent management via a mobile application.

Founded in 2007 with a registered capital of 300 million RMB, Ningbo Deye Inverter Technology Co. is a Chinese high-tech company and a subsidiary of the Deye Group. Covering an area of more than 15,000 square metres and equipped with comprehensive production and testing facilities, Deye has established itself as a major player in the global solar inverter market.

The company specialises in providing complete solutions for photovoltaic energy production systems, covering both residential and commercial installations. Deye offers devices to suit every need: all types of modules, connected and stand-alone arrays, hybrid inverter systems, and applications ranging from small domestic systems to large commercial systems in the megawatt range. The product range includes photovoltaic inverters from 1 to 136 kW, hybrid inverters from 3 to 50 kW and microinverters from 300 to 2000 W.

As a technology company, Deye is dedicated to researching and developing cutting-edge technologies to offer products that are both efficient and reliable. For example, Deye uses the three-level T-type topology and the improved SVPWM algorithm to increase conversion efficiency by 0.7% over conventional SPWM algorithms.





FAQ - Pylontech LiFePO4 batteries & solar storage

1. What is a Pylontech battery used for in a photovoltaic system? +
A Pylontech battery stores the solar energy produced during the day so you can use it later (evening/night), increase self-consumption and, depending on the system configuration, provide backup power.
2. What type of lithium battery is Pylontech? +
Pylontech offers LiFePO4 (lithium iron phosphate) batteries, a chemistry known for its stability and durability in energy storage applications.
3. How do I choose the battery capacity (kWh) for Pylontech? +
Capacity depends on your consumption, the loads you want to supply, the autonomy you need, and your solar production. In self-consumption, sizing often aims to cover evening/night usage; off-grid systems are sized for 24/48 hours (or more) depending on constraints.
4. Can I expand my storage by adding Pylontech modules? +
Yes. A key advantage is modularity: you can increase capacity by adding modules, within the manufacturer’s recommendations and the inverter/charger limitations.
5. Is Pylontech compatible with all inverters? +
Compatibility depends on the inverter/charger model and integration requirements: system voltage, communication protocol (CAN / RS485), parameters and commissioning procedure. Always check the compatibility list and recommended settings before installation.
6. CAN or RS485: which communication should I use? +
It depends on the inverter and the chosen wiring/architecture. Some systems prefer CAN for battery data exchange, others use RS485. Follow the compatibility recommendations and commissioning guide.
7. Are Pylontech batteries suitable for off-grid systems? +
Yes, they can be suitable for off-grid use if the overall system is designed for autonomy: PV sizing, battery capacity, inverter power, and a backup strategy (generator, etc.) if needed.
8. Which accessories are useful with Pylontech batteries? +
Depending on your configuration: interconnection cables, mounting racks/supports, communication components and, for some ranges, control modules. These accessories help with integration, cable safety and maintenance.
9. Where can I find a commissioning guide (e.g., US5000)? +
Check our technical resources and installation guides (depending on the model). For example, Wattuneed provides a dedicated guide for installing Pylontech US5000 batteries: Pylontech US5000 installation guide.
