Solar Grid Storage selected AllCell Technologies as a preferred supplier of large lithium-ion battery systems for their PowerFactor solar + storage systems. The Solar Grid Storage PowerFactor™ system provides commercial solar project developers with a turnkey energy storage solution bundled with an inverter, reducing project costs.
AllCell’s passive thermal management system (earlier post) allows Solar Grid Storage to place both the battery system and inverter into a single ISO container—a significant reduction in complexity, cost, size, and weight compared to other options in the market today.
The Solar Grid Storage PowerFactor storage system allows solar developers a simple and cost-effective way to integrate storage into projects typically ranging from 100 kilowatts to 10 megawatts, the company said. The PowerFactor inverter acts as a standard solar inverter delivering AC power to the building but also can be used during power outages enabling the PV system plus batteries to provide emergency power indefinitely.
AllCell’s battery system, protected by the company’s proprietary thermal management system, offers a safer, longer lasting, and more economical solution than conventional large scale batteries. Effective thermal management is important in any battery system, but it is especially critical in larger high-power systems. AllCell’s patented technology utilizes a composite phase change material (PCM) to surround each cell within the battery, absorbing and distributing heat to reduce battery temperature and prevent thermal runaway propagation. The PCM technology allows the PowerFactor system design to maximize safety and cycle life.
Solar Grid Storage has several projects in the 14-state PJM service area including the recently announced Grid Star project at the Philadelphia Navy Yard and the Konterra commercial microgrid in Laurel, Maryland.
