Management Team


In 2013 Phil and Trish bought a new 21ft caravan that they wanted to fit out with a quality solar power system, however, there were no companies offering integrated, customised solutions for off-grid power for caravans and other RVs.  They undertook extensive research and produced a business plan to set up a company and register the trading name Solar 4 RVs.  Product testing was conducted to ensure their range of integrated products were of the highest quality and specifically suited to caravans and RVs.

The business quickly expanded into marine applications and providing engineered solar power solutions for mobile off-grid industrial applications.  They registered the trading names 'Solar 4 Boats' and 'Solar 4 Industry'.  The business has one numerous awards recognising the leadership in lightweight solar.

In early 2020 son Chris and his partner Amie became Directors of Solar 4 RVs and took over the day to day management of the business with Phil and Trish providing support.  Phil now looks after battery management system sales plus has input into various projects. 

Chris and Amie are committed to ensuring customers have complete satisfaction with their solar power purchase.   Their matching work ethics and complementary skill sets are the key to their success.
