DC-DC converter

A DC-DC converter that is between the battery bank and DC loads.

DC-DC converters are used to power appliances that run on a different voltage than the energy storage system supplies. There are two types of DC converters: step-down DC converters (output a lower voltage) and step-up DC converters (output a higher voltage). The majority of loads are designed for use with 12 V systems, fewer for 24 V systems, and very limited options for use with 48 V systems. A step-down DC converter to 12 V from 24 V or 48 V is the most common application.

A DC-DC converter is rated based upon the maximum current that it can pass through. They can be sized as follows:

Minimum current rating of the DC-DC converter	= Sum of all the power rating of all loads/lights ÷ Output voltage
