Are EG4 components compatible with my existing electrical system?
+
Yes, EG4 components are designed for seamless integration with standard residential electrical systems. Our system includes a smart electrical panel that ensures compatibility without requiring expensive main panel upgrades. This integration enables whole-home backup capability while supporting future electrification projects like EV charging, heat pumps, and electric appliances—potentially saving you $5,000-$10,000 in future upgrade costs.
What makes EG4's battery backup superior to other options?
+
Our EG4 battery system provides 29 kWh of storage—larger than a Tesla Powerwall plus expansion pack (27 kWh total). This extra capacity, combined with EG4's high-rate discharge capability (16 kW), ensures your entire home remains powered during extended outages. Unlike systems that only support essential circuits, our EG4 integration enables true whole-home backup for days, depending on your energy usage.
How long do EG4 batteries last?
+
EG4's lithium iron phosphate batteries offer exceptional longevity, with a projected lifespan of 6,000+ cycles while maintaining over 80% of original capacity. For most residential applications, this translates to 15+ years of daily use. Our proprietary software further extends battery life by optimizing charge/discharge patterns based on usage habits, grid conditions, and weather forecasts.
Can EG4 hardware be monitored remotely?
+
Yes, all EG4 components integrate with our user-friendly monitoring platform. Through our intuitive mobile app, you can track solar production, battery status, home energy consumption, and grid interaction in real-time. The system allows for circuit-level monitoring and control, enabling you to optimize energy usage while remotely managing your home's power. Our service team also proactively monitors system performance to ensure optimal operation.
What warranty coverage comes with EG4 hardware?
+
EG4 components come with comprehensive warranty coverage: 10 years on the inverter and battery system, 25 years on solar panels, and 5 years on the smart electrical panel. Beyond manufacturer warranties, Potrero Energy provides ongoing system support and optimization through our remote monitoring service, addressing potential issues before they impact performance and ensuring your system operates at peak efficiency throughout its lifespan.
Is EG4 hardware certified and code-compliant?
+
Absolutely. All EG4 components meet rigorous UL safety standards and comply with National Electrical Code requirements. These certifications ensure safe, reliable operation while satisfying utility interconnection standards. Our installations adhere to all local building codes and permit requirements, with our experienced team handling the entire permitting process to ensure a compliant installation.
How does EG4 hardware support grid-balancing capabilities?
+
EG4's advanced battery and inverter technology enables sophisticated grid-interactive capabilities. With 16 kW power export capacity, our systems can provide substantial grid support services. Our proprietary software orchestrates charging during periods of abundant renewable energy and discharging during high demand, generating revenue through grid-balancing programs. This capability not only provides passive income but also contributes to a more resilient and efficient electrical grid.
