Product Q&A

Q:What working modes does your energy storage system support, and can it be connected to a photovoltaic system?

It supports three working modes: off-grid, grid-connected and hybrid power supply. It can seamlessly connect to photovoltaic inverters to realize self-consumption, surplus power storage and grid power supply, maximizing the utilization of clean energy.

Q:What core protection functions does the BMS of the energy storage system have?

The BMS has overcharge, overdischarge, overtemperature, overcurrent, short-circuit and cell balancing protection functions, which real-time monitor the battery status to ensure the safe and stable operation of the system and avoid potential safety hazards.

Q:What conditions are required for the installation and commissioning of the energy storage system, and does your company provide technical support?

A flat and ventilated installation site (indoor/outdoor) and access to voltage lines that meet specifications are required. Our company provides complete installation drawings and operation manuals, supports remote commissioning, and can also arrange engineers to provide on-site guidance (fees are negotiable separately).
