    Why this size

    A 55–65 in LED TV typically draws 100–150 W. We size the continuous rating at 125% of running watts and check that the surge rating (usually about twice the continuous rating) covers the startup.

    Frequently asked questions

    How long will a 100Ah battery run a tv?

    About 6.5 hours from a 12 V 100 Ah lithium battery at a steady 150 W (less for cycling appliances, more for intermittent ones).

    Do I need a pure sine wave inverter?

    Yes for motors, compressors, medical devices and modern electronics.
