The heart of a standalone power system — built to run a whole property 24/7 in conditions where grid-tied gear wouldn't last a summer.
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."
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.

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.

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 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.
