Frequently Asked Questions
How should I choose the UPS capacity?
Start with the measured continuous load, startup or peak demand and expected expansion. DAXIN ENERGY can review the load list and recommend a practical operating margin.
How is battery runtime determined?
Runtime depends on load, battery voltage, battery capacity, battery age, temperature and inverter efficiency. Share the required backup duration and normal load for a project calculation.
Can this UPS work with a generator or remote monitoring system?
Generator and monitoring compatibility depends on the selected model and configuration. Confirm generator capacity, frequency stability and the required RS-232, RS-485, USB, Modbus or SNMP interface before ordering.
