Sweet Dreams Power System
The Sweet Dreams Power System is a complete 48V electrical system designed to power a modern camper van without compromise. Built around the same 10.2 kWh battery bank we use in our Sweet Dreams show van, it provides the power needed to run air conditioning, microwave ovens, induction cooktops, water heaters, refrigerators, lighting, fans, outlets, and other everyday appliances.
Unlike traditional 12V systems, the Sweet Dreams Power System uses a 48V architecture to reduce wiring losses, improve efficiency, and support high-power loads with ease. The result is a powerful, expandable electrical platform capable of supporting extended off-grid travel.

Designed for Real Van Life
The Sweet Dreams Power System is designed for travelers who want residential-level electrical capability in a camper van. Whether you’re cooling the van on a hot summer day, making coffee in the morning, running a microwave, charging laptops, or spending days away from hookups, this system delivers the power and capacity needed to travel comfortably.
The Sweet Dreams Power System is a high-capacity 48V electrical system built around two 48V 100Ah LiTime batteries, providing over 10 kWh of energy storage—enough to comfortably run air conditioning, refrigeration, lighting, hot water, induction cooking, electronics, and other everyday appliances. Based on a 600W solar array, a 1,500W DC-DC charger, and two hours of driving per day, the system is expected to generate approximately 4,830 Wh of energy daily while consuming about 3,497 Wh, resulting in a surplus of 1,333 Wh per day. In practical terms, this means the system produces more energy than it uses under normal conditions, allowing for extended off-grid camping without relying on shore power while maintaining substantial battery reserves for cloudy days and heavier-than-normal usage.
