⚙How It Works
A low-voltage power conversion system (PCS) is a bidirectional AC/DC converter: in one direction it rectifies grid AC to charge the battery, and in the other it inverts battery DC to feed the grid or loads. The PCS-LV platform serves 48 V or low-DC battery banks, with a fast transfer capability that islandes the system and keeps critical loads powered when the grid fails, plus black-start to re-energise a de-energised network.
▦Structure & Composition
The PCS-LV contains a low-DC input stage, a bidirectional two-level IGBT bridge, an LCL filter and a contactor network that manages grid-tie and islanded operation. A DSP controller runs the grid-following and grid-forming algorithms, while CAN and Modbus ports hand charge/discharge commands to the BMS and EMS. The enclosure is IP20 for indoor installation with forced-air cooling.
Applications
Selection Guide
- Residential and small commercial storage where the battery runs at 48 V or a low DC bus.
- Match the PCS rated power to the battery's charge/discharge C-rate, not just the load.
- Choose a unit with black-start if the site must rebuild a local grid after an outage.
Frequently Asked Questions
What does bidirectional mean for a PCS?
It charges the battery from AC and discharges the battery to AC through the same bridge, so one unit handles both directions of energy flow.
What is grid-forming mode?
The PCS synthesises its own voltage and frequency reference, letting a storage system run islanded or rebuild a network without a utility reference.
How fast does it respond?
Millisecond-scale power response qualifies the PCS for frequency regulation and fast reserve services.
