Our Why

Ron and Francis have spent more than 60 years combined working in 12V, marine, agricultural and off-grid power, long before TOPO existed. That work kept running into the same problem: a proper dual battery system meant a full day with an auto-electrician, or a pile of separate boxes wired together by hand. TOPO exists to build plug-and-play 12V dual battery systems that stop that trade-off. 

Our Story
TOPO DC Power is a family-owned Australian manufacturer, based in Western Australia, that’s become one of the country’s go-to names in 12V dual battery systems. Every unit is designed and built here, by the people who built the company.
