What's included
What's Included in Battery Backup
Keep the lights on. Beat peak rates. Sleep better.
Battery storage isn't a luxury anymore — it's the missing half of a real energy system. We size every battery around the loads you actually want to back up, not a generic kWh number from a brochure.
Tesla Powerwall, Enphase IQ, and FranklinWH — we're certified on all three and we recommend the system that fits your home, not the one we have in stock.
Time-of-use rate plans have rewritten the math. A properly sized battery now saves money every single day, not just during outages, by storing cheap mid-day solar and discharging during peak evening pricing.
What you get
- Whole-home and partial-home backup options
- Tesla Powerwall, Enphase, and FranklinWH certified
- Daily time-of-use savings on peak rates
- Seamless transfer during grid outages
- Stackable capacity — start small, expand later
- Smart load management for critical circuits
