Ador Digatron showcased its 1.25 MW ADPCS1250 PCS at the exhibition
The product offers three grid-interactive operating modes – PQ, VF, and VSG – with a rated full-load power conversion capacity of 1,290 kW
It supports island mode during no-grid conditions and connects multiple converters in parallel
Ador Digatron, a joint venture between India’s Ador Powertron and German energy storage and battery maker Digatron Power Electronics, presented its ADPCS1250 power conversion system (PCS) at REI 2026.
A PCS is a bidirectional (charging/discharging) converter that enables grid pairing between storage and the grid. It also supports grid-interactive functions depending on the client's requirements and local regulations. This product accommodates six modular PCSs, rated at 215 kVA each, within a 1,600 × 1,000 × 2,250 mm (W × D × H) cabinet frame. The company says this distributed architecture eases operation & maintenance (O&M) without requiring a total system shutdown like in a centralized PCS. Its DC side has six input channels, each rated for a voltage range of 1,000 to 1,500 V and a current of up to 180 A. In grid-tied conditions, each PCS can convert up to 215 kW of (3-phase) power at 600 V, for a total system capacity of 1,290 kW.
The system offers three operating modes: PQ, VF, and VSG. In PQ mode, the PCS locks in the grid voltage and frequency (grid-following) and tracks active (P) and reactive power (Q) setpoints in real time. On the other hand, it switches to VF mode in case of a grid failure to set and regulate the AC bus voltage and frequency (grid-forming). After transitioning to virtual synchronous generator (VSG) mode, its dynamic behavior in weak-grid scenarios helps improve grid frequency or voltage stability. It can shift to island mode and connect multiple PCSs in parallel (off-grid parallelism) to deliver and absorb MW-scale power (each PCS contributes up to 237 kW) at a local voltage and frequency in no-grid conditions.
The product datasheet specifies an operating temperature range of -30 to +60°C, with derating starting above 45 °C, and forced-air-cooling-based thermal regulation. For safety, it features an MCCB on both the DC and AC sides, along with a surge arrester on the AC side only.
