Off-Grid & Rural Solar Systems
Independent power for remote Queensland properties, where connecting to the grid costs more than generating your own.
On rural and hinterland properties across South East Queensland, a grid extension can cost more than an entire standalone power system. Off-grid design is unforgiving: undersize the array or the battery bank and you run the generator every winter evening. SEBSS models seasonal generation, worst-case cloudy runs, and pump and shed loads before specifying anything.
What’s Included
- Standalone power systems with roof or ground-mount arrays
- 24V and 48V battery banks sized for winter, not summer, generation
- MPPT charge controllers and hybrid inverter-chargers
- Automatic diesel or petrol generator start as backup
- Bore pump, dairy, shed, and irrigation load modelling
- Remote monitoring so faults are diagnosed before you lose power

How We Deliver
Load Audit
Every pump, motor, shed, and appliance is listed with duty cycle and starting current.
Seasonal Modelling
Generation is modelled against winter sun hours so the system holds up in the leanest month.
Install & Commission
Array, battery bank, inverter-charger, and generator changeover are installed and tested as one system.
Remote Support
Monitoring lets us diagnose issues remotely rather than waiting on a site visit.
Frequently Asked Questions
Is off-grid cheaper than a grid connection?
Frequently, yes. Once a grid extension runs beyond a few hundred metres, the connection quote often exceeds the cost of a properly engineered standalone system with no ongoing supply charge.
Will I still need a generator?
Most off-grid systems include one as backup rather than as a primary source. Correctly sized, it may run only a handful of times a year during extended overcast periods.
Can it run a bore pump or dairy?
Yes, but motor starting current has to be designed for from the outset. This is exactly why we audit loads before specifying an inverter rather than after.
How long do the batteries last?
Modern lithium banks typically deliver ten years or more of daily cycling when sized so they are not routinely discharged to empty, which is a key part of how we specify capacity.
