The Hawk’s Nest Solar and DC-DC Charging System
The Hawk’s Nest combines a robust 900-watt rooftop solar array with a Sterling BB12120 DC‑to‑DC charger, delivering up to 120 amps (1,200 watts) directly from the van’s upgraded 220-amp alternator while driving. Most van builds rely on just 30–60 amps of DC charging and underpowered solar, but this dual system ensures rapid battery recovery in all conditions. Whether stationary or in motion, the system actively powers high-demand appliances and recharges the 840Ah lithium battery bank without reliance on shore power—maximizing runtime and true off-grid capability.
