UL 9540 is the new safety standard for energy storage systems (ESS), focusing on fire safety. This standard comprises UL 1973-certified battery pack(s) and a UL 1741-certified inverter. UL 9540 certification isn't required in all states and jurisdictions yet, but is increasingly becoming so. Whether your locality requires it or not, using an energy storage system that conforms to UL 9540 is a good idea.
This UL 9540-certified 48V ESS kit provides all the main components you'll need for 15kWh of safe, compliant, and reliable solar power storage. It is based upon:
|10 Year Extended Life Warranty||7.5 Year Extended Charge Rate Warranty|
|Low Voltage Cut-Off||48.2V|
|High Voltage Cut-Off||57.0V|
|Cycle Life||6000 cycles (80% DoD)||4000 cycles (80% DoD)|
