Why Voltsen

Engineered to handle whatever Australia throws at it.

LFP & LMFP cells

Automotive-grade lithium iron phosphate chemistry. 3,000+ cycles, no thermal runaway risk, safer in your van than lithium-ion.

Solar-ready MPPT

Every Roam, Camp and Base unit takes solar input directly. Plug in a Voltsen Sun panel and recharge anywhere with sky above.

Pure sine wave AC

Run sensitive electronics, CPAP machines, laptops and fridges without harmonic noise. The same waveform you get at home.

Fast charge

0–100% in around an hour on the larger Roam units. Top up at a servo, recharge at camp from solar, or trickle from the car.

UPS on select models

Roam 1800 and Base 2400 include uninterrupted-power-supply switchover for blackouts — your fridge keeps running, you keep working.

Built for Aussie heat

Tested for high-ambient operation. Active cooling, IP-rated solar panels and intelligent thermal management for outback summers.

Off-grid, on the road, or back at home.

Pair any Voltsen power station with a foldable Sun panel and you've got a silent, self-contained energy system. No fuel. No fumes. No noise. No extension lead.
