The DC25 Distribution Box supports 12V lead-acid (wet, calcium, Gel, AGM) as well as lithium batteries.
The primary charge input supports 12V and 24V vehicle systems and will provide up to 25A of current to
the auxiliary battery using an optimized 6-stage charge algorithm.
to fridges and other small appliances. These connectors can also be used with external battery chargers
as an alternative to the built-in dedicated charge port.
Heavy-duty connectors can be used for connecting a variety of accessories from inverters (600W max)
The introduction of two dual-port USB modules with fast charge allows several smart devices such as
smart-phones, tablets, GPS, cameras and other USB-devices to be powered up to 18W on each port.
A built-in 25A MPPT solar regulator circuit supports solar panels up to 42V and provides up to 25A (375W)
charge current to the battery.
