Use Cases
Residential Solar Energy Storage: Pair with rooftop solar panels to store generated power during the day and use it at night, reducing household electricity costs. Acts as a backup power source during outages to keep appliances running. DKL-5 is ideal for small homes, DKL-10 for standard households and villas, and DKL-15 for large villas with high power demand.
Commercial / Small-Scale Industrial Energy StorageConvenience stores, retail outlets, and small factories: arbitrage via peak-valley electricity pricing. Store energy during off-peak hours to use during peak times, reducing costs. Ensure uninterrupted power for critical equipment during outages.
Backup Power for Communication Base StationsProvides stable backup power for outdoor communication base stations and signal towers to ensure uninterrupted connectivity.
Power for Agricultural EquipmentOff-grid power for agricultural irrigation and outdoor livestock equipment, meeting clean energy needs in remote areas without grid access.
Off-grid standalone PV systemFor remote mountain areas, log cabins, RV parks, and other off-grid locations without utility power: pair with photovoltaic panels to create a standalone off-grid power system.
