low-voltage DC solar system like the ones in cars,
trucks, sailboats, and RVs.
Omitting the inverter has lots of advantages.
First, it makes solar installation cheaper because
inverters are expensive. Second, it makes the
system more energy efficient. Converting low-
voltage DC to high-voltage AC power involves
energy losses as high as 50% for small-scale
solar installations. And there are additional
losses (at least 5%–15%) in the AC/DC adapters
of all those devices that operate internally on low
