List of products by brand Pylontech

Pylontech designs LiFePO4 lithium batteries dedicated to energy storage for photovoltaic systems (self-consumption, backup, off-grid site). Founded in 2009, the brand is a major player in BESS solutions, with a certified approach and modular configurations.



Choosing the right Pylontech battery

Pylontech batteries (LiFePO4 lithium) are designed for energy storage on photovoltaic installations. To select the right model and capacity, here are the criteria to check before purchase.

  • Your use case: self-consumption (day/night), backup or off-grid site.
  • Capacity (kWh) & autonomy: size according to your consumption, the devices to be powered, and the desired duration.
  • Voltage & architecture: check your system configuration (e.g., 48 V depending on the models).
  • Scalability: choose a modular solution if you want to increase capacity later.
  • Compatibility & communication: depending on the inverter/charger, check prerequisites (CAN, RS485, settings and commissioning procedure).

Tip: for a professional installation, also consider accessories (cables, brackets/racks, control modules depending on the ranges) to ensure neat wiring and compliant integration.

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.
