For industry and C&I
0.4–0.8 kV connection without transformer costs
SINEXCEL LV solutions connect directly at 0.4 or 0.8 kV, so a BESS can be deployed without the capital cost of a step-up transformer. In the InterConti solutions catalogue, they are rated at 2.5 or 3.15 MW with 5–10 MWh of storage capacity. The system strengthens a facility’s energy resilience and lowers electricity costs.
-
Direct connection — to the site’s 0.4 or 0.8 kV substation, with no additional transformer and lower losses.
-
Peak shaving — the battery discharges during peak load hours, reducing contracted demand.
-
Tariff optimisation — charging at off-peak rates and discharging at peak times (active consumer mode / demand response).
-
Island mode — backup power for critical equipment during grid outages.
-
Solar PV integration — grid-tied PV inverters connect to the BESS with no additional transformers.

PCS and MV station for the Cornex-to-grid chain
Combine CORNEX DC blocks with SINEXCEL PCS (StellaON PWX) and SES4H centralised MV stations for a fully matched chain, from the battery container to the 6–35 kV point of connection. In the InterConti solutions catalogue, power ranges from 2.5 to 10 MW, and a single MV Skid supports 5 to 40 MWh of storage capacity.
-
Modular PCS — StellaON PWX 1250/1575 kW, up to 99% efficiency; up to 4 units in parallel on both AC and DC sides.
-
Grid-forming / grid-support — VSG/PQ/VF modes; on-grid and off-grid operation.
-
Black start and fault ride-through — LVRT/HVRT, fast market response and power quality control.
-
DC-DC — PDS1-750K-H bidirectional converters, 500–1500 V, for DC-coupled PV + storage.
-
Local partner — InterConti Trading supports design, supply and service in Ukraine.
