Product Introduction

The Lynx C Series is a rechargeable Li-ion battery system designed for use with solar energy systems. The battery is capable of storing excess energy generated by the solar panels during the day and releasing it during peak usage times. This results in reduced dependence on the grid and lower energy bills.

Product Overview

The Lynx C Series includes a battery module, management unit, and power conversion system. It has a modular design, allowing users to add or remove battery modules to fit their energy storage needs. The system is compatible with most solar inverters on the market.

Product Usage Instructions

Before using the Lynx C Series, read the user manual carefully and follow all safety precautions. Install the battery system in a safe and dry location, away from any heat sources or flammable materials. The battery system must be installed by a qualified technician who is familiar with electrical and battery systems.

During normal operation, the battery system will charge during the day when solar energy is available and discharge during peak usage times in the evening. The battery system can be monitored using the GoodWe monitoring system or other monitoring software. Any abnormal behavior or malfunctions should be reported to a qualified technician immediately.

When performing maintenance on the battery system, follow all safety precautions and disconnect the battery from the solar inverter and electrical system. Only use authorized replacement parts and accessories, and do not attempt to repair or modify the battery system yourself.
