Square Inverter with Indicator has wide range of capacity from 250 VA to 3 KVA and wide range dc bus from 12 V to 48 V. The Inverter has automatic time driven charger restart method instead of voltage sensing to reduce electric bill and automatic battery health check up and bad battery detection by battery intelligent software. The Inverter has audio and visual indications for overload, low battery and charger on and constant current constant voltage charging method. The Inverter ensures mains input output wrong connection protection, 200 V to 250 V open loop regulated output voltage from inverter and transfer time of 20 ms. The Square Inverter with Indicator has the feature of power failure checking by different methods and near RMS calculation for better accuracy and synchronized change over to reduce the transfer time.
