How Your Storage Works for You
Multi-energy complementarity with flexible scheduling to maximize ROI
Peak-Valley Arbitrage
Charge during off-peak, discharge during peak. Capture price spreads — in many regions, peak-to-off-peak ratios exceed 3:1.
Demand Charge Management
Shave peak loads to reduce maximum demand readings. Lower monthly capacity charges with optimized two-cycle dispatch strategies.
Solar Self-Consumption
Store excess PV generation instead of exporting at low feed-in tariffs. Maximize behind-the-meter utilization of your solar investment.
Emergency Backup
Automatic off-grid transfer during grid outages. Keeps critical production loads running without interruption.
