Description
The HPCS-75040-200K on-grid and off-grid energy storage PCS converter is constructed with V2G high-frequency isolation modules. It can be flexibly configured into different power levels and battery voltages according to requirements. Combined with STS, it can achieve seamless on-grid and off-grid switching to ensure that the load does not lose power.

Product Features:
- More secure and reliable:
- Full high-frequency isolation design ensures the safety between the battery and the grid/load;
- Battery-friendly, with battery grouping access, reducing battery string connection, avoiding battery circulation issues, and extending battery life;
- Compatible with DC sides of battery grouping access modules from different manufacturers and with different characteristics;
- Grid-friendly, with AC sides connected in parallel, exhibiting stand-alone characteristics.
- Higher efficiency:
- High-frequency isolation between the battery and the grid eliminates the power frequency transformer, with high-frequency isolation efficiency reaching over 95%.
- More intelligent and user-friendly:
- Equipped with an STS module to achieve seamless switching during grid disconnection;
- Covers multiple battery voltage levels for passenger vehicles (100V~750Vdc), with a wide battery voltage range.
- Lower cost:
- Compared to traditional modular energy storage, high-frequency isolation eliminates the power frequency isolation transformer and indirect costs (such as cabinets and fans), resulting in low system cost.
- More flexible configuration:
- Supports 19-inch standard rack installation with a compact structure;
- Modular hot-swappable design for flexible system configuration;
- Flexibly configure energy storage converters with different power levels and battery voltage levels according to demand.
