List of products by brand Fronius

Fronius is an Austrian technology company specialising in solar home systems. It offers GEN24 Plus inverters, batteries, intelligent energy management via mobile application, and chargers for electric vehicles, ensuring performance, security and scalability for Belgian households.

Founded in 1945 as a one-man business, Fronius is now an integral part of the industry. Over the past three quarters of a century, we've grown as a family business from a regional specialist repair shop to a global player. Our story began with the company's founder, Günter Fronius, who earned his living doing maintenance work. Then came the idea that would set everything in motion: the qualified electrical engineer produced a device that recharged car batteries, allowing them to be used for longer.

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.
