Frequently Asked Questions
What is the W16-5S designed for?
The W16-5S is a 15.36 kWh sodium-ion battery for residential energy storage. With a compatible inverter, it can be used for solar self-consumption, backup power and scheduled energy use. It is a battery unit and requires the appropriate external system equipment.
How much storage can I add in parallel?
The product supports up to 20 units in parallel, giving a maximum total nominal energy capacity of 307.2 kWh. The final configuration, wiring and inverter capacity must be checked for the project.
Can the battery charge in freezing weather?
The specified charging range is 0°C to 55°C. The wider −40°C to 60°C range applies to discharge only. Installation and system controls must keep charging within the permitted temperature range.
Where can the floor-standing unit be installed?
The specified installation environment is indoors or under outdoor eaves. The enclosure is rated IP65. A qualified installer should confirm the supporting surface, access, clearances and site conditions for the approximately 188.2 kg unit.
How do I check inverter compatibility?
Send us the inverter brand, model and intended operating mode. The battery provides RS232, CAN and RS485 interfaces, but the communication protocol and system configuration must also match the selected inverter.
What does the 9,000-cycle rating mean?
The datasheet specifies 9,000 cycles at 80% depth of discharge, 25°C and a 0.5C rate. This is a laboratory rating; actual battery life depends on temperature, operating profile and system management. It does not define a fixed number of service years.
