Connecting a 12V battery directly to a 48V inverter will not work because the inverter requires at least 48 volts to operate. The inverter may not turn on, or if it does, it could enter protection mode due to insufficient voltage. This mismatch can potentially damage both the battery and the inverter.
[pdf] Below you will find an overview of all DC/DC converters from 260V to 48V DC direct voltage. These converters are stabilized, short-circuit proof and can operate with 260V DC input voltage. All DC/DC converters on this page have an output voltage of 48V DC. This voltage is adjustable for many types.
[pdf] The modified sine wave inverter delivers 600-watt peak power and converts 12V DC from battery or car lighter to AC 110V or 220V household power. Come with a USB port, 12V to 110V inverter can be a universal outlet for fast-charging electronic devices.
