Energy storage PCS Bi-directional ACDC module

Enjoypowers EPCS series bidirectional AC/DC converter for energy storage features a three-level topology, enabling seamless conversion between DC and AC. It efficiently charges the battery by converting AC to DC, and also provides AC power to the load or feeds excess energy back to the grid.

Rated power: 30kW, 50kW, 62.5kW, 80kW, 105kW，Multiple modules can be paralleled up to 1MW
Rated voltage: 400Vac
Grid frequency: 50/60Hz ± 10%
DC side voltage range: 615~950(3P3L)/680~950(3P4L)

Energy storage PCS Introduction

Features

Three-level topology, the highest conversion efficiency >98.5%
High dynamic response, full load switching time as low as 10ms
Support multi-machine parallel operation, expandable to 2MW
Modular equipment makes the configuration more flexible and easy to maintain
High-speed IGBT, low internal resistance filter
Off-grid seamless switching, fast response, to ensure continuous and uninterrupted power supply of key loads
Wide DC input range, supporting cascade battery utilization
Independent adjustment of active and reactive power to improve power quality

Typical Application Scenarios

Energy storage, lithium battery testing
AC/DC analog power supply, electronic load
Energy storage inverter
Peak shaving and valley filling: store electricity when the electricity price is low, and discharge it during the peak period of electricity consumption, saving electricity cost
Uninterrupted power supply: When the power grid fails, the system can provide uninterrupted off-grid power supply to ensure the normal operation of the load
Dynamic capacity increase: Compensate for short-term power resources shortage and delay power distribution investment
Power quality management, compensation for transient drop of grid voltage, load power factor and harmonic current
Can form a hybrid microgrid system
