# RV Air Conditioners TURBRO Cuts Inverter Losses with the Greenland GLD15 By Amy Duong | Written with AI assistance | Published 2026-10-27 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/rv-air-conditioners References: [prnewswire](https://www.prnewswire.com/news-releases/turbro-brings-48v-dc-air-conditioning-to-the-growing-off-grid-rv-market-302919634.html)  TURBRO's Greenland GLD15 brings direct 48V DC rooftop cooling to RVs built around higher-voltage battery banks, removing the external inverter step. That native DC setup is framed as a 25% thermal-efficiency gain, giving off-grid owners a way to run climate control with less energy lost in power conversion. The rooftop unit delivers 15,000 BTU of cooling and also works as a [heat pump](https://www.trendhunter.com/trends/ductless-heat-pump), folding summer AC and cooler-weather heating into one piece of hardware. Because it is made for compatible 48V systems, it suits owners who are already upgrading their rigs for [longer boondocking trips](https://www.trendhunter.com/trends/ae1) and custom electrical layouts, instead of treating high-demand cooling as an add-on. Native 48V operation turns [rooftop air conditioning](https://www.trendhunter.com/trends/hvac-system) into a cleaner match for RVs that already use lithium banks and solar charging. Available through TURBRO, the GLD15 widens DC climate control by treating higher-voltage builds as a design target instead of a workaround.
