Backup Batteries, Power When You Need It

The SolarEdge Home Battery offers 9.7 kWh usable capacity per battery with 5 kW continuous power output (7.5 kW peak). It features DC-coupled design for 94.5% round-trip efficiency, advanced monitoring via the mySolarEdge app, and flexible installation options (indoor/outdoor, wall/floor mount). The system is UL9540A compliant and backed by a 10-year warranty with 70% capacity retention guaranteed.

Backup batteries can provide up to 45 hours of runtime when powering only essential loads like refrigerators, lights, and medical devices. For whole-home backup, runtime typically ranges from 8-24 hours depending on usage patterns. When paired with solar panels, your backup time can be extended indefinitely during daylight hours as the panels recharge the batteries.

Backup battery systems typically range from $14,500 to $22,000 installed. Financial benefits include: offsetting peak electricity rates by using stored energy during expensive time-of-use periods, reducing demand charges, maximizing solar self-consumption (avoiding selling excess solar at low rates), and protection from grid price volatility. Most homeowners see 5-7% annual ROI through energy cost savings, with systems paying for themselves within 10-15 years while providing invaluable backup power security.

Backup batteries provide true energy independence by storing solar energy for use anytime - day or night. Advanced features include automatic severe weather event detection that prepares your system before storms hit, intelligent energy management that optimizes charge/discharge cycles, and seamless grid integration that allows you to reduce reliance on utility power. You control your energy destiny rather than being at the mercy of grid outages and rate increases.

Backup batteries are a solid investment backed by robust 10-year warranties with 70% capacity retention guaranteed. They provide dual value: daily energy cost savings through time-of-use optimization and peak shaving, plus critical backup power during emergencies. Unlike generators, batteries require no maintenance, no fuel costs, operate silently, produce zero emissions, and can be used every day - not just during outages. With 6,000+ cycle lifespans (15+ years), increasing grid instability, and rising electricity costs, batteries deliver long-term value and peace of mind.

Depends on battery size and usage. A typical whole-home system provides 1-3 days of backup for essential loads, longer when paired with solar. A single 9.7 kWh battery can power essential circuits for up to 45 hours.

Yes! Batteries can charge from the grid during off-peak hours and provide backup power during outages or peak rate periods. However, pairing with solar maximizes your savings and energy independence.

Batteries are silent, emissions-free, require no fuel, activate instantly (within milliseconds), and can be used daily for energy cost savings - not just during outages. Generators are noisy, require regular maintenance, consume fuel, and are typically only used during emergencies.

Most home battery systems last 10-15 years with minimal degradation. SolarEdge batteries come with 10-year warranties guaranteeing at least 70% capacity retention and are rated for 6,000+ charge cycles.

Absolutely! Battery systems are modular and scalable. Start with one 9.7 kWh battery and add more as your energy needs grow. This future-ready design protects your investment and adapts to changing household requirements.
