What sizes of containerized BESS does SiRay supply?

SiRay containerized BESS starts at 1.2 MWh in a 20-foot container (ESS-1M2-20FT) and scales to 2.411 MWh in a 40-foot container (ESS-2M4-40FT) at 768 V nominal.

Can a SiRay microgrid run fully off-grid?

Yes. PV, battery storage and a diesel genset are dispatched by the EMS; the PCS forms the voltage and frequency reference in island mode, with transfer under 10 ms.

Does SiRay publish prices on its website?

No. BESS and microgrid pricing depends on capacity, container count, shipping and local balance-of-plant, so SiRay quotes per project on request.

Which markets does SiRay serve?

SiRay focuses on weak-grid and off-grid markets in Southeast Asia and Africa, including island resorts, mining and aggregate sites, and factories facing peak-shaving bills.

What battery chemistry does SiRay use?

SiRay uses LiFePO4 (lithium iron phosphate) cells throughout its storage range, including 51.2 V 314 Ah modules in the stationary cabinets and containers.
