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.
