Basant products produces power inverters with regulated charging from 160v-270v by constant current [8 amp]. These inverters are protected from mains high voltage and low voltage i.E. From 140v to 270v working range for mains mode also over charge protection is provided to battery. The advantage of these inverters is that battery can be charged on very low voltage [160 v mains input] . Some of the features of these inverters are: full wave thyristor controlled charging for more stability; inverter mode output waveform is quasi-sine wave for no-noise running appliances; inverter output short circuit protection. Battery status bar graph is also provided to keep a watch on battery status.
