Project Case Study
Tigo Solar Troubleshooting and Battery Backup Upgrade in San Jose
A Cambrian-area San Jose homeowner asked BNV Electric to troubleshoot a solar production issue and plan a battery backup upgrade. BNV inspected the existing solar equipment, identified a failed optimizer issue, restored the affected solar operation, and added battery backup equipment.
What BNV Was Asked to Solve
The home already had a solar system, but the customer noticed lower-than-expected production and a cracked panel. They also wanted to explore adding battery backup to the system.
BNV Electric inspected the array and equipment path before moving into the battery upgrade scope, keeping the troubleshooting and backup planning connected.
Planning Around Existing Conditions
The system used Hyundai bifacial panels with Tigo power optimizers. During inspection, BNV found the issue was tied to failed optimizer equipment beneath the affected panel, not just the visible panel damage.
The project then moved from troubleshooting into a broader battery-backup upgrade, with attention on equipment placement, backup switching, and serviceable electrical integration.
Clean Equipment Integration
BNV Electric restored the affected solar operation and added battery backup equipment with the existing system conditions in mind. The public case study keeps the focus on the work, not the private homeowner details.
For similar solar customers, this kind of project starts with diagnosis: what is not working, what equipment is already installed, and what loads the owner wants to support with backup power.
The Takeaway
This project shows why solar and battery work often starts with troubleshooting. A good backup-power plan depends on understanding the existing system, equipment condition, panel capacity, and the loads the owner wants to support.
