Why 48V Off-Grid

Power that doesn't tap out on night two.

Most trailers run a 12V house system that loses energy to heat and bogs down under load. The Apex X23 is built on a 48V architecture — the same approach used in modern EVs and home batteries.

48VOLT

The Architecture

Lower current for the same power — less loss, more headroom for the 3,600W inverter.

400Ah EQ.

The Storage

400Ah-at-12V equivalent lithium, standard — reserve past a single overnight.

1,360WATTS

The Recharge

400W roof solar standard; 1,360W total with the 48V solar awning.

Roof solar is standard. The 48V solar awning is an available upgrade. Real off-grid runtime depends on your loads, weather, and how you camp.

The Hardware

Engineered for the long way out.

Every detail of the Apex X23 is built for ultimate freedom — premium components, rugged capability, and off-grid performance that holds up where the pavement ends.
