Core Services
1. Inverter Replacements & Solar Repairs
Many South Australian homes are equipped with ageing solar systems, often inherited by new homeowners or suffering from inverter faults. Jousto has built a reputation as the go-to provider for solar repairs and inverter replacements—with a fast-response service model that prioritises uptime and performance recovery.

Common inverter issues such as red lights, error codes, or significant drops in output are diagnosed and resolved with a blend of hands-on electrical know-how and advanced system analytics. Whether the fix involves a simple reset or a full system upgrade, Jousto delivers efficient, cost-effective outcomes that restore solar savings and ensure compliance with local energy regulations.

2. Solar System Upgrades
For households with underperforming or legacy solar systems, Jousto provides expert upgrade pathways. This includes panel additions, rewiring, or integration of smart monitoring and hybrid inverter systems for battery-readiness.

Upgrades are tailored to specific property profiles and are designed to optimise ROI through better self-consumption, load balancing, and higher yields over time.

3. Heat Pump Hot Water Systems
Jousto also installs heat pump hot water systems—a rapidly growing alternative to electric or gas water heaters that utilises ambient air to heat water efficiently. With rebates available under South Australia’s sustainability programs, homeowners can often replace old units with high-efficiency heat pumps at reduced out-of-pocket cost, while slashing their water heating bills.

4. Air Conditioning Solutions
The business also supplies and installs ducted and split-system air conditioners, focused on performance, energy ratings, and room-specific needs. Customers benefit from brand-agnostic advice, competitive pricing, and precision installation that balances comfort with cost-efficiency.

Each system is quoted and installed by a qualified electrician—not a salesperson—ensuring clients get the right solution the first time.
