Our Why
We started TOPO because dual battery systems shouldn’t be too complicated. TOPO units are simple to plug and play, giving you more power than you’ll ever need to out last the trip. 

Our Story
Father and son team Ron and Francis have been building DC power gear in Australia for over 40 years — marine electronics, solar, off-grid systems — before TOPO was TOPO. When Ron got tired of watching mates pay $2,000+ and wait weeks for an installer, he built the plug-and-play system he wished existed. That’s still the only question we ask about a new product: would this save someone a weekend and a call-out fee?
