Why Sodium-Ion for Home & Light Commercial

Where Lead-Acid and
Lithium Fall Short,
Sodium-Ion Delivers.

Lead-acid requires maintenance and degrades quickly. Lithium-ion carries thermal runaway risk and struggles in cold environments. The 48V Series R eliminates all three problems with sodium-ion NFPP chemistry — the safest, longest-lasting residential battery available.

01
Safety-First Design
Zero Thermal Runaway Risk

Sodium-ion chemistry is inherently non-flammable and non-toxic. Safe for indoor residential installation — no fire suppression, no special ventilation required.

  • Zero thermal runaway incidents
  • Non-hazardous shipping — no dangerous goods classification
  • No toxic gas emissions
  • Safe in garages, basements, and utility rooms
  • Lower insurance risk vs. lithium-ion
02
Extreme Temperature Performance
Full Capacity in Any Climate

Reliable operation from −20°C to +60°C. Works in garages, basements, and outdoor enclosures where lithium-ion loses 20–40% of capacity in cold conditions.

  • Full capacity at −20°C — no cold-weather derating
  • No battery heating systems required
  • No thermal management complexity
  • Minimal derating across full temperature range
  • Ideal for cold-climate installations
03
Exceptional Longevity
6,000+ Cycles, 20-Year Life

6,000+ cycles at 80% depth of discharge and a 20-year design life provide decades of reliable backup power and solar storage — minimal degradation over time.

  • 6,000+ cycles @ 80% DoD
  • 20-year design life at 25°C
  • Minimal capacity degradation over time
  • No watering, no acid spills, no maintenance
  • Lower lifetime cost than lead-acid or lithium

How It Pays You Back

Four Ways Your Battery Saves & Earns

The Series-R doesn't just store energy — it actively reduces your utility bill and generates income across four independent savings streams, simultaneously optimized by Coulomb AI™.

40%
Bill Reduction

Store solar energy during the day. Discharge at night or peak rate hours. Reduce your utility bill by 20–40% through time-of-use optimization, automated by Coulomb AI™.

90%
Solar Self-Consumption

Maximize the value of every solar panel on your roof. Store excess generation instead of exporting at low feed-in rates. Use your own power at night when rates are highest.

+$
Grid Services Income

Enroll in utility demand response and VPP programs through GridIQ™. Get paid by your utility for providing grid stability during peak demand events — with zero manual effort.

24/7
Backup Protection

Keep your home powered through grid outages — refrigerators, lights, Wi-Fi, and medical devices. Coulomb AI™ automatically reserves backup capacity based on your priorities.
