ESS scales to meet exact capacity needs

Denchi has launched an ESS energy storage system that can be scaled to the exact needs of energy sources, avoiding wasted capacity.

The SLICE system uses modular architecture with an array of 3.5kWh battery units, using durable Lithium Iron Phosphate (LFP) cells. Up to 13 of these arrays can be placed in each cabinet. The cabinets are then combined together to meet the specific storage capacity criteria defined by the customer, with no excess needing to be paid for, which is often a major drawback of ESS systems.

Large enterprise and university campuses, industrial plants, sports stadia and residential complexes can all execute grid balancing and peak shaving, avoiding charges for excess energy use. The scalability allows smaller agricultural or community microgeneration sites will be able to draw on electricity from renewable resources as needed, regardless of the time of day or weather conditions, or use it to generate revenue by selling electricity surpluses back to the grid when demand levels are high.

The batteries in the SLICE cabinets are all connected to a sophisticated management subsystem using Modbus TCP/IP connectivity. In addition to allowing remote control, this provides monitoring data of the operational performance and can assist with other real-time diagnostic tasks via a cloud interface. The analytics include charge/discharge profiles as well as in-depth assessment of cells’ cycling lifespans, as well as regulating ambient temperature and humidity. Fault detection mechanisms for over-current, over-voltage, over-temperature and Earth-leak protect against potential damage during power outages, and the system includes a fire suppression system.

“Suitable for both grid-connected and off-grid implementations, SLICE represents a simple and convenient way through which our customers can take full control of the energy usage, and gain significant financial rewards as a result,” said Nick Simmons, Sales Director at Denchi Group.

Next: ESS integration

“It means charging can be undertaken at off-peak times, when utilities’ pricing is low, then the electricity subsequently consumed as demands dictate. Likewise, energy from renewable resources can be brought online as and when they are needed,” he said.

The SLICE platform has been designed to be easy to integrate into existing infrastructure. It can be installed directly inside customers’ premises, or housed externally within shipping containers placed on site and comes with a 10 year warranty.
