Mercedes Sprinter 170 Solar Calculator
The 170 gives you the roof real estate the 144 wishes it had. Full-time builds routinely fit 600–800 W here, which comfortably covers Starlink, remote work, and some electric cooking. The trade-off is weight and payload, so size the battery to the loads rather than filling the roof for its own sake. A 400–600 Ah LiFePO4 bank matches a big roof for genuine off-grid weeks.
Roof space: About 75–95 sq ft of roof — enough for 600–800 W without crowding vents.
