BATTERY ENERGY STORAGE SYSTEMS (BESS)
C&I ESS 100 kW – 2.5 MW — commercial energy storage system
Country: China · Model: C&I ESS
A commercial energy storage system built from PCS modules of 100 or 125 kW and expandable to 2.5 MW. The BOS-B Pro-A3 battery unit has a capacity of 257 kWh at a system voltage of 819.2 V. It is designed for industrial, retail and agricultural sites with their own solar plant, where the storage smooths consumption peaks and holds a reserve.

Description
The system is assembled from three types of power modules and rack-mounted LFP batteries. The PCS converts energy between the battery and the AC grid in both directions and has a built-in EMS, so the charge and discharge logic sits in the converter itself. The 200 or 250 kW MPPT module connects the PV array to the storage DC bus, with up to 10 trackers of 48 A each, which suits roofs with slopes facing different directions. The 500 kW STS moves the load to battery power in less than 10 ms, and most equipment rides through a grid failure without restarting. The battery is built on 314 Ah cells, with a lifetime of at least 6000 cycles at 0.5C down to 70 % remaining capacity. Monitoring, settings and updates are handled through the Cloud.
How to choose
Sizing starts with the PCS power. Modules of 100 or 125 kW are combined until the total covers the peak load, and the upper limit of the system is 2.5 MW. Capacity is added in blocks of 257 kWh, and their number depends on how many hours the site must run on the storage. Such a BESS is excessive for a private house, where the ALL-IN-ONE HOME ESS with 16 kWh modules and expansion up to 96 kWh is more suitable, and for a balcony solar plant there is the SUN-BK Micro Hybrid ESS rated 2.56 or 5.12 kWh.

FAQ
What maximum power can be reached with PCS modules?
PCS units are made for 100 and 125 kW, and the system is scaled by connecting modules in parallel up to 2.5 MW.
What is the capacity of one BOS-B Pro-A3 battery unit?
The unit has 257 kWh and is built on 314 Ah LFP cells, with a nominal system voltage of 819.2 V.
How many cycles does the commercial storage battery withstand?
The manufacturer states at least 6000 cycles at 0.5C until capacity drops to 70 % of the initial value.
How fast does the system switch to backup mode when the grid fails?
The 500 kW STS module switches the load to the storage in less than 10 ms.
How many trackers does the MPPT module of the commercial ESS have?
The 200 or 250 kW MPPT module has up to 10 trackers, each accepting current of up to 48 A.
