Off-Grid Battery & Solar Retrofit
Frequent local power outages and rising peak utility rates led this homeowner to upgrade their existing solar array with a smart battery storage system. We retrofitted an AC-coupled 10 kWh battery system and upgraded electrical subpanels—providing seamless blackout protection and zero energy waste.
Project Journal
Initial diagnostic review revealed that while the home possessed an operational rooftop solar array, the lack of energy storage left the property entirely exposed during frequent evening utility blackouts and peak time-of-use rate surges. Excess daytime generation was being sent back to the grid for minimal credit while high evening rates eroded overall solar savings.
Our installation crew mounted a 10 kWh smart lithium battery storage assembly adjacent to the main electrical panel. We integrated a dedicated essential-loads subpanel, isolating high-priority circuits including refrigeration, home office power, lighting, and security infrastructure.
Using advanced AC-coupling technology, we connected the battery system directly to the existing solar inverter without disturbing current roof warranties. Testing confirmed instant 10-millisecond automatic grid disconnect and battery takeover during utility power loss, guaranteeing continuous power security.
