Applications
Self-Consumption with Solar Energy Storage
The Roca2-5KL's integrated hybrid inverter captures excess solar power, stores it in the battery, and converts it back to AC electricity whenever your home needs it-day or night. Maximize on-site solar energy storage to reduce grid draw and slash your utility bills.
Benefits:
- Continuous use of clean, renewable energy
- Lower monthly electricity costs
- Smarter home energy utilization
Peak-Shaving via Off-Peak Charging
Schedule Roca2-5KL to charge during cheaper, off-peak hours and discharge when electricity rates are highest. This intelligent peak-shaving strategy lets you avoid expensive grid tariffs and enjoy significant electric bill savings without changing your daily routine.
Benefits:
- Leverages lower time-of-use rates
- Automatically reduces peak-hour consumption
- Simplifies cost-effective energy management
Uninterrupted Backup Power during Outages
In the event of a grid failure, Roca2-5KL delivers instant backup power (10 ms transfer) to keep essential appliances running-lights, refrigeration, medical devices, and more. Enjoy reliable home backup power and peace of mind during storms, blackouts, or other emergencies.
Benefits:
- Rapid switchover for zero downtime
- Supports critical household circuits
- Enhances home safety and comfort
