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

Battery power display
