An off-grid inverter does a much harder job than a grid-tied one — it has to run a whole property 24/7, handle big surge loads, integrate a backup generator, and keep going in temperatures that shut grid-tied gear down. These are the four brands we trust on systems that have to "just work."

The off-grid inverters we install

Deye

Hybrid & off-grid inverters

Deye has grown into one of the world's largest inverter manufacturers, and they're our go-to value brand when a customer wants solid, well-supported gear without the premium of the Selectronic or Victron names. Serious global production behind them, a broad range that covers most of the jobs we take on, and Australian support that's matured a lot in recent years — with fast warranty turnaround when it's needed.

Fronius

AC-coupled solar input

On off-grid systems with serious solar input, we AC-couple a Fronius to the battery inverter to handle the PV side. Austrian engineering, 24/7 monitoring, and the kind of reliability that pays for itself when there's no grid to fall back on — Fronius has earned its place on our hardest off-grid jobs.

Selectronic

Australian-made since 1981

Built in Melbourne for over 40 years — the off-grid workhorse for serious Australian properties, from small homesteads up to larger rural and small-commercial jobs. Ten-year warranty, native AC-coupling with Fronius, and unmatched local service. Our default for off-grid jobs that absolutely have to keep running.

Victron Energy

Highly configurable off-grid inverters

Victron is the Swiss-army knife of off-grid. Every parameter configurable through their VRM remote monitoring, generator integration built in, and battery-agnostic so we're not locked to a single chemistry. Our pick when a site has unique loads or a tricky generator setup that needs a system bent to fit it.
