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. **Mannual 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 stabilize for first 3S otherwise itoperates in Battery mode
