665V Battery Energy Storage System
The KHZH 665V 20kWh Energy Storage System is a compact and powerful energy storage solution that integrates solar power generation, energy storage, and power conversion into one unit. This system allows you to harness free solar energy to power your home, office, or equipment. It can also store excess energy for use when sunlight is unavailable or during power outages. The plug-and-play construction makes it easy to install – simply connect your solar panels and plug the system into a power outlet or generator to get started.
Commercial and Industrial Applications
Our lithium batteries are widely used in solar and wind energy storage systems to store energy generated during the day for use at night or during periods of low production. This feature ensures a consistent and reliable power supply, even when renewable energy generation fluctuates. The 48V integrated energy storage cabinet supports series and parallel connections, allowing users to expand their systems to meet higher power demands. For example, connecting 16 units in series can offer a 62kWh capacity for larger-scale industrial or agricultural applications, such as powering equipment or irrigation systems.
