8000 cycles Cycle life @90% DOD 314 Ah large-format LFP cells. At one cycle a day, that is over 20 years. 98.5 % Max discharge efficiency Sentinal 261 reaches 98.5% max discharge efficiency, system efficiency ≥94%, so less energy is lost. 10 ms Grid / off-grid switching Sentinal 100 switches between grid-tied and off-grid in <10 ms, keeping critical loads running. 3 models Capacity options 100 / 233 / 261 kWh, enough for peak-shaving and backup needs from parks to mid-size industry. 261 kWh Max capacity per cabinet The 125 kW / 261 kWh liquid-cooled flagship, with two-hour shifting and more controllable peak and demand savings.
Applications

At home in every kind of industrial site.

From urban parks to rural microgrids, Sentinal covers the main commercial and industrial storage scenarios with one product line.

Factory park peak shaving
Factory park · Peak shaving Charge off-peak and discharge at peak to cut demand charges by moving load away from high-price hours.
Commercial building PV self-consumption
Commercial building · PV self-consumption Rooftop PV plus storage raises self-consumption and lowers energy and capacity charges.
Rural microgrid off-grid backup
Rural / microgrid · Off-grid backup In weak-grid or remote areas, PV plus storage supplies base power and rides through outages (up to 10 units in parallel off-grid).
PV and storage EV charging station
PV + storage + EV charging The integrated machine takes PV directly, generating by day and storing by night to support charging and backup, and can be combined with dual-axis tracking.
