Can a ModX2 be relocated or expanded later?

Yes to both, with different degrees of effort. Battery capacity scales from one to three modules within the existing enclosure, so a site whose load grows, an extra camera, a comms upgrade, additional telemetry, can be uprated without replacing the system. Additional solar arrays are available as an option where generation rather than storage is the constraint.

Relocation is straightforward mechanically: the unit is designed to be lifted with batteries in situ, so a move is a crane, a transport permit and a new slab rather than a decommissioning exercise. That is a meaningful consideration for temporary construction, exploration and monitoring campaigns where the asset outlives the site.

Where relocation is the primary requirement rather than an occasional one, V-Trail is the better platform. It is trailer-mounted and designed to be towed and redeployed repeatedly.
