Our Commercial and Industrial ESS solutions support energy capacities ranging from 100 to 344kWh that can meet the flexible configuration needs of various scenarios. The products support both on-grid & off-grid operation modes, provide UPS function, and can realize flexible expansion, thereby maximizing investment returns and ensuring energy independence for clients. We also incorporate self-developed software to simply manage microgrid applications and participate in electricity spot market transactions in the form of virtual power plants (VPP), proactively embracing new power systems.
Topology Drawing

100kW/215kWh All-In-One Energy Storage System is an integrated battery energy storage system comprising a lithium-ionbattery pack (hereafter referred to as PACK), a power converter system (hereafter referred to asPCS), an energy management system (hereafter referred to as EMS), a liquid thermal managementsystem (hereafter referred to as LTMS), and a Thermal Runaway Suppression System. Through EMSmanagement, it achieves the storage and release of electrical energy.Battery Charging: Controlled by the EMS, the PCS converts mains electricity or other powersources into direct current to charge the batteries, storing energy within them.Battery Discharging: Controlled by the EMS, the stored battery energy is converted by the PCSinto alternating current to supply power to the load.

Application
Peak-valley arbitrage

Peak Shaving and Valley Filling: The system automatically charges during off-peak hours when electricity rates are low and discharges during peak demand periods. This load-shifting strategy significantly reduces demand charges and overall energy costs for businesses.
PV Energy Time-Shift

Solar Self-Consumption Optimization: For facilities with rooftop solar PV systems, the ESS captures excess solar energy generated during the day that would otherwise be fed back to the grid at low rates. This stored energy is then used during evening hours or cloudy periods, maximizing the return on investment for solar installations.
