ENERGY STORAGE SYSTEM

CompatibleSunceco energy storage systems (ESS) consist of lithium batteries (LFP) and work great with all solar brand inverters and charge controllers.

SafetySunceco ESS include Battery Management System (BMS) with on-board DC disconnect. If BMS detects any problems, an automatic contactor disconnects ESS from the incoming charge.

Advantages• 48V / 192V Complete Energy Storage System• Battery Management System (BMS)• Indoor Model Enclosure• Seven year prorated warranty• Optional wireless management• High precision monomer battery voltage detection (plus

or minus 2 mV), provide accurate charge/discharge protection.

• High precision multi-point temperature detection; detection precision of +/- 1 °C

• Support full-time active balance, balance current greater than 5 A to prevent the imbalance between the battery core maintenance battery capacity, extend the life of the battery pack

• High precision detection (+/- 1%) effectively prevent charge and discharge current is too large, the damage to the battery

• For each battery uses the distributed SOC estimation, penetrate into every string of battery for battery power management control, effectively improve the battery life

• Modular structure, strong extensibility, the biggest can support 360 series of batteries in series

• Lithium Iron Phosphate (LFP) battery uses a lithium-derived chemistry well known for light weight and very high discharge rates. LFP also provides better safety characteristics than lithium-ion batteries with other cathode materials.

• Distributed micro-grid can be achieved through combining energy storage system and PCS

• The flexible operation mode of distributed micro-grid improves the energy supply reliability on users’ side

• To ensure the reliability of local power supply while serious voltage flickering and falling occur on the external power grid, operation of critical loads will be isolated by using a static switch and in terms of loads’ importance

• Able to reduce the transmission losses and the increasing costs of power grid upgrade investments. For users, widespread use of micro-grid can reduce electricity prices for maximum economic benefit.

• Using the electricity price difference between peak and valley period, micro-grid an transfer electricity to the grid during peak period, and purchase power directly from the power grid with low price during the valley period

• Parallel mode for multiple machine: centralized or independent

• Centralized mode: using single 48 V 200 Ah or greater capacity battery system and additionally provide backup power and photovoltaic surplus energy storage to multiple grid-connected inverter

• Independent mode: by individually providing a 48 V 100 Ah or a 200 Ah battery system to each of the paralleled inverters, multiple sets of independent battery energy storage system therefore can obtain the accumulated capacity of energy storage battery through paralleled inverters

MW-level energy storage power plant is designed to improve the operation curve of the plant (shaping the peak and valley), reducing the line losses of power transmission, enhancing the lifespan of power lines and equipment, optimizing the power resource layout of the power system, improving power quality, slowing down the reconstruction and adjustment needs of city power grid, improving the safety and stability level of power grid, smoothing power storage and stabilizing the output of power grid, and ensuring energy supply, etc.
