Off-Grid
Self-Sufficient Power, Designed for Real Conditions.
Off-grid is not just a bigger solar system. It's an engineered package — array, battery chemistry, inverter topology, generator, monitoring — all sized to your real load, your worst week of weather, and how you actually use the property. Patterson Electrical designs and installs stand-alone power systems for homes, sheds, granny flats, agricultural buildings and weekenders across South East Queensland and the Scenic Rim.
Every system is delivered with full documentation, single-line diagrams and a remote-monitoring portal so you can see exactly what your power is doing — from anywhere.
What we deliver
Off-Grid Specialties
⚡
Solar Arrays
Roof or ground-mount arrays with robust DC isolation, optimisers where needed, and clean cable management.
⚡
Lithium Battery Storage
Premium LFP battery banks with proper BMS, ventilation and labelling — sized for at least 2–3 days of autonomy.
⚡
Hybrid Inverters
Victron, Selectronic and SMA inverter/chargers with grid-forming output and seamless generator switching.
⚡
Backup Generators
Auto-start diesel or LPG gensets integrated to top up batteries during extended cloudy periods — no manual intervention needed.
⚡
Remote Monitoring
VRM, SolarAssistant or equivalent dashboards so you can see SoC, loads and yields from your phone.
⚡
Bushfire-Resilient Builds
Fire-rated cabinets, BAL-rated penetrations and loads prioritised to keep critical circuits running during outages.
⚡
Service & Maintenance
Annual checks of battery health, terminal torque, inverter firmware and array performance.
