This video shows the solar build for the 16' X 7' X 7' tall V nose trailer build. The solar build has a 272 amp hour, 48 volt, lithium, 13 KwH battery that is charged by the 1400 watts of solar panels on the roof. At the heart of the system is a 3000 W Growatt solar pure sine wave hybird inverter controller. The system will run all operations of the trailer to include the 9000 watt split system HVAC for many days. With the summer sunshine - I have run it without limit. This trailer build took me over a year to complete working on it weekends and after hours. I hope you enjoy the information.
