Bidirectional inverter (PCS) for energy storage systems ±2500 kW
Country: Japan · Model: PCS ±2500 kW
The PCS bidirectional inverter of ±2500 kW active power (2500 kVA apparent) is for BESS battery energy storage systems. It charges the battery from the grid and returns energy back, smooths the output of PV and wind plants, shifts energy in time and supports voltage and frequency stability. The product is at the planning stage, so all parameters are targets for now.

Description
The DC side works in the 750–1250 V range, the AC side at 480 V with a frequency of 50/60 Hz ±3 %. The isolation transformer is external, that is, it stands outside the inverter cabinet, and it is selected for the grid voltage of the site. The power section is built on a three-level topology, with a target maximum efficiency of 98.5 %. Cooling is hybrid, a fan works together with a heat pipe heatsink, and this technology has already been proven on Solar Ware solar inverters. The inverter exchanges data with the control system over Modbus and Ethernet, and the communication interfaces scale to the size of the site. The cabinet is designed for outdoor installation depending on site conditions, at a temperature from -5 to +40 °C, relative humidity of 5–95 % and altitude up to 1000 m above sea level. The developer has experience integrating large battery systems in Asia, Europe and North America, and for hybrid sites also offers its own energy management system.
How to choose
The rating of one ±2500 kW unit sets the step by which storage power is increased. The battery rack voltage must stay within the 750–1250 V window from full charge to end of discharge, so the number of series-connected modules is calculated from both extreme values. For a smaller PV plant with storage there is the modular Solar Ware Ninja at 800–880 kW with DC voltage up to 1500 V, and for pure generation without batteries the central Solar Ware Samurai up to 3360 kW.

FAQ
What power does the bidirectional PCS inverter for BESS have?
Active power is ±2500 kW in charge and discharge modes, apparent power 2500 kVA. The values are targets, since the product is at the planning stage.
What battery voltage is needed for this PCS?
The DC input is designed for 750–1250 V. The battery voltage must fit within this range in all operating modes.
Is a separate transformer needed to connect the PCS to the grid?
Yes, the isolation transformer is external. The inverter delivers 480 V AC at 50/60 Hz, and the transformer is selected for the grid voltage at the site.
What is the efficiency of the 2500 kW storage inverter?
The target maximum efficiency is 98.5 % with a three-level power topology and hybrid cooling.
Can the PCS be installed in the open air?
Yes, subject to site conditions. Operating temperature is from -5 to +40 °C, humidity 5–95 %, altitude up to 1000 m.
