Power Problem What Firefly Does Response Time Protection
Sudden Power Spike A jolt of too much voltage that can damage electronics ⚡ Cuts off the grid instantly. Your home switches to clean power from battery and solar, then reconnects automatically once the grid is safe again. ⚡ <20ms ✓ Full
Weak or Unstable Power Low voltage that makes lights dim and wears out appliances 📉 Switches to battery. Your refrigerator, AC, and well pump keep running on clean, steady power — no overheating, no early failure. ⚡ <20ms ✓ Full
Complete Power Outage The grid goes completely dark 🌑 Keeps your home running, seamlessly. Most devices won't even flicker. Solar and battery carry you through until power returns. ⚡ <20ms ✓ Full
Dirty or Unstable Power Quality Power that's technically on, but not clean enough for sensitive electronics 〰️ Isolates and cleans it up. Firefly detects the problem and delivers stable, clean power from your own system instead. ⚡ <20ms ✓ Full
Long or Planned Outages Rolling blackouts or extended outages that last hours 🔋 Keeps going for hours. Your essentials run on battery and solar — typically 4 to 12+ hours, often longer as solar recharges the battery during the day. ⚡ <20ms ✓ Full
Lightning Surges Fast, powerful jolts during storms 🌩️ Strong protection, with a recommendation. Firefly handles most surges, but direct lightning is extreme. We recommend adding surge protectors to your most valuable electronics for complete peace of mind. ⚠ Partial ~ Partial

A Silent Guardian, Always On
Firefly watches your power 60 times every second. It's working quietly in the background — day and night — so you don't have to.
⚡
Nothing for You to Do
No switch to flip. No app to open. No generator to start. When something goes wrong with the grid, Firefly handles it before you even notice.
🛡️
Longer Life for Your Appliances
Bad power quietly damages refrigerators, AC units, and well pumps over time. Clean power from Firefly protects them — so they last longer and cost less to replace.
💡
Our Recommendation
For complete peace of mind, we suggest adding surge protectors to your most valuable electronics. Together with Firefly, you'll be covered from every angle.
