EW2000 PRO Inverter advantages
Rated Power: 750VA, 1KVA, 1.5KVA, 2KVA, 3KVA, 5KVA
* Pure sine wave output
* Built in AVR
* Auto restart while AC input
* user-friendly LED indicators and LCD display, showing battery voltage, and load power percentage.
AC INPUT: indicates green | when grid is normal, the light will be always on. |
BATTERY: indicates yellow | when the battery voltage is normal, the light will be always on |
BYPASS: indicates yellow | when the output of the bypass is normal, the light will be always on |
AC OUTPUT: indicates green | when the output is normal, the light will be always on |
FAULT: indicates red | The light will be always on when there is fault and will flash when alarms |

USB or RS232
* Intelligent HMI function (human machine interface)
* Multiple setting functions: output frequency, charging current, average charging voltage, floating charging voltage, battery under-voltage turn-off point , buzzer on/off.
* Multiple protection function: over-voltage & under-voltage for battery, over-voltage & under-voltage for AC, over-frequency & under-frequency for AC, over-current output, short-circuit, over-temperature protection.
