In Ballarat, our services specialize in the repair and diagnostics of all types of solar systems, including off-grid systems, grid-connected systems, and grid-connected systems with batteries. Here are the key aspects of our service:

1. Inverter Repairs: We frequently handle repairs of inverters, particularly in systems that were installed around ten years ago, usually ranging from 1.5kW to 5kW capacities, with 3-4kW systems being less common. Inverters often begin failing after about 10 years, primarily due to wear and tear. The costs for replacements are approximately $900 for a 2kW inverter and about $1400 for a 5kW inverter.
2. Panel Performance: Generally, the solar panels themselves continue to perform well without any issues related to cables or connections, which highlights the quality and durability of the panels even as other components may fail.
3. Lead-Acid Battery Replacement: For off-grid systems installed over six years ago, before lithium batteries became available, the most common issue is the depletion of lead-acid batteries. When the existing solar panel array is too small, an effective solution is to expand the array by adding more panels along with an additional charge controller.
4. System Replacement vs. Repair: In cases where the battery system has completely failed, particularly in older 24V systems for which no replacement batteries are available, it is often more cost-effective to replace the entire system rather than attempting repairs. This approach also allows for the integration of modern, more efficient technologies.

These points outline our comprehensive approach to maintaining and upgrading solar energy systems to ensure optimal performance and longevity.
