Enphase IQ Energy System Components
Common Battery Storage Applications
Self-Consumption
Maximize solar investment by storing excess daytime generation for evening use. This application reduces grid dependence by capturing surplus solar energy during peak production hours, then deploying stored power when panels are inactive, effectively extending solar benefits into nighttime hours.
Time of Use Optimization
Strategic energy arbitrage captures grid power during off-peak periods when utility rates are lowest, typically overnight hours. The stored energy is then utilized during high-rate periods, reducing electricity costs by avoiding peak pricing while maintaining consistent power availability throughout the day.
Battery Backup
Critical load protection ensures essential circuits remain powered during grid outages. Modern battery systems automatically detect utility interruptions and seamlessly transition to stored energy, maintaining operation of vital appliances, medical equipment, and communication devices without manual intervention.
AC Coupled vs. DC Coupled Energy Storage Systems
AC-Coupled Batteries for Solar
AC-coupled battery systems store both solar-generated and grid-sourced power as alternating current (AC), the standard electricity type used by most household appliances. This technology is gaining traction due to its unique benefits.
Example AC Coupled Batteries: Enphase IQ Battery 10C, FranklinWH aPower 2, PointGuard Home, Fortress Power eForce, Sol-Ark Hybrid Inverters, HomeGrid Stackd Series
Pros:
- Simplified integration with existing grid-tied solar systems, making retrofitting more straightforward.
- Each solar panel with its own microinverter maintains individual production, minimizing system-wide outages.
- Modular design allows for easy expansion of battery capacity over time without disrupting the entire system.
Cons:
- Solar power may undergo multiple conversions (DC to AC from microinverters, then potentially AC to DC for battery storage, and back to AC for home use), leading to marginal efficiency losses.
DC-Coupled Batteries for Solar
DC-coupled battery systems store the direct current (DC) electricity directly from your solar panels. This approach is generally more efficient as the DC-to-AC conversion occurs only once, often sharing a common inverter for both panels and batteries.
Example DC Coupled Batteries: SolarEdge Home, Sol-Ark Hybrid Inverters, HomeGrid Stackd Series, Fortress Power eForce, Briggs & Stratton SimpliPhi, Deka Duration
Pros:
- Higher overall system efficiency due to fewer DC-to-AC conversion stages.
- Batteries and panels share the same inverter
- Can be lower cost than AC coupled
Cons:
- Higher wiring costs with the DC cabling
- More challenging to retrofit with existing grid-tied solar installations, often necessitating the replacement of the original inverter.
