Frequently Asked Questions
How much backup power do I need for my home?
The amount of backup power needed depends on your energy usage and which appliances you want to keep running during an outage. A typical American home uses 20-30 kWh of electricity per day. For essential loads (refrigerator, some lights, internet, and select outlets), a 10-13.5 kWh battery is usually sufficient. For whole-home backup including HVAC systems, you’ll typically need 20+ kWh of storage capacity, which can be achieved by installing multiple battery units.
How long will a battery backup last during a power outage?
Battery runtime depends on the battery capacity and your energy consumption. A 13.5 kWh battery like the Tesla Powerwall can power essential loads (refrigerator, lights, internet, etc.) for about 12-24 hours, or a few critical circuits for 1-2 days. With solar panels charging the battery during daylight hours, you could potentially maintain power indefinitely during daylight periods, as long as your solar system generates enough energy to meet your needs.
Can I go completely off-grid with solar and batteries?
Yes, it’s technically possible to go off-grid with a properly sized solar and battery system. However, this typically requires a larger investment in both solar panels and multiple battery units to ensure reliable power year-round. For most homeowners, a grid-tied system with battery backup offers the best balance of cost and reliability, allowing you to use grid power when needed while still having backup power during outages.
What's the difference between AC and DC coupled battery systems?
In a DC-coupled system, solar panels connect directly to the battery system through a charge controller, which then connects to an inverter to power your home. This is more efficient for new installations. AC-coupled systems have solar panels connected to a grid-tied inverter, and batteries connect through their own separate inverter. This setup is easier to retrofit to existing solar installations but has slightly lower efficiency due to multiple conversions between AC and DC.
How long do home batteries last before needing replacement?
Most modern lithium-ion home batteries come with 10-year warranties, guaranteeing they’ll maintain at least 70-80% of their original capacity during that period. However, the actual lifespan often extends to 15+ years with proper use. The battery’s longevity depends on factors like depth of discharge, number of cycles, temperature conditions, and management system quality. Premium systems like Tesla Powerwall and Enphase IQ Battery include advanced management systems that help maximize battery life.
