Compact size Excellent microprocessor control guarantees high-reliability Boost and buck AVR for voltage stabilization Auto restart No load auto shutdown as default however User can press the button for 10s to disable this default setting. **Manual selection for low(<20W) load operation Simulated sine wave Off-mode charging & Cold start function **High load(>270W)protection in AVR mode **To Switch in AC mode I/P AC supply voltage(230V) should be stabilized for the first 3S otherwise it operates in Battery mode
