Automatically switch battery power supply when there is no mains powerECO modeSimilar as Line priority mode.When the load power accounts for less than 10% of the inverter power, the inverter will automatically shut down, and when the load power accounts for 11%~100% of the inverter power, it will automatically startBattery priority modePrioritize the use of batteries to supply power to the load. When the battery voltage is higher than the battery recovery voltage, the battery supplies power to the load; when the battery voltage is lower than the battery low-voltage protection voltage, the inverter will automatically switch from the battery power supply to the Utility power supply, and automatically charge the battery after switching to the Utility power supplyGenerator modeSimilar as Line priority mode.Generator output should within 165~275vac and 45~65hz.Unattended modeInverter will always under ON or STANDBY status. when battery voltage is low , the inverter will auto shut down AC output and enter STANDBY status. Once battery been charged it back to the restore point, the inverter will restart the AC ouput. OtherTransfer timeBult- in AC bypass replay (≤8ms) DisplayLCD Display with function buttonsCooling systemIntelligent fan air cooling, fan speed is adjusted by real temperature. ≤45ºC slow fan, ≥45ºC fast fanComnunicationRS485,support wifi box and external control screen for remote control and mornitoring.(WIFI box & External Contol Screen sell seperately)EnvironmentTemperature-20~+75ºCHumidity
