Using a 72V battery with a 48V controller is not recommended, as it can lead to serious damage to the controller and other components. The controller is designed to handle specific voltage levels, and exceeding these limits can cause overheating, failure, and potentially render. . When it comes to choosing between a 48V system and a 72V system, there are several factors to consider. Both systems are widely used in various applications, especially in renewable energy systems like solar power setups, off-grid systems, and electric vehicles (EVs). The core function of a battery is to store DC electrical energy. Whether it's electricity generated by solar panels or energy charged from. . A 48V inverter is a device that converts 48 volts of direct current (DC), which is normally stored in a battery, to alternating current (AC), which is used to power common household appliances.
