With the EU's Renewable Energy Directive (RED II) requiring an increase in the proportion of green electricity in the business sector to 45% by 2030 and accelerating the phase-out of fossil energy dependence, European companies are facing multiple challenges from fluctuating electricity prices, carbon compliance pressures and energy efficiency upgrades. Especially in Germany, the Netherlands and other industrial powers, the sharp fluctuations in natural gas prices and the stability of the power grid have forced the manufacturing industry, logistics parks and other scenes to seek more flexible energy management solutions. The AK-PCS1 series two-way power conversion system (PCS) launched by ARK Tech, with the core advantages of "multi-energy coupling, intelligent scheduling, plug and play", has become a key hub for the construction of microgrids, helping enterprises realize the role transformation from "energy consumer" to "energy manager".
The core value of ARK PCS stems from its modular bidirectional conversion architecture. The system integrates AC/DC, DC/DC bidirectional conversion module and built-in isolation transformer to support the flexible access of photovoltaic arrays, energy storage batteries, power grids and loads: - multi-energy complementary scheduling: During the day, photovoltaic energy can be directly supplied to the load (efficiency of 98%), the surplus electricity is converted into direct current energy stored in the battery through PCS; At night or in rainy days, the battery energy storage is continuously powered by PCS inverter for AC power supply, forming a closed-loop energy ecology of "photovoltaic direct supply + energy storage peak regulation". The actual measurement of an auto parts park in Germany shows that the mode increases the self-absorption rate of renewable energy to 75%, completely replacing the traditional diesel generator backup power supply. - Two-way power flow: Support grid (Utility-interactive) and off-grid (Stand alone) dual mode, the grid normal and the main network two-way interaction (power factor -1 to 1 adjustable), to achieve peak cutting and valley filling; When the power grid fails, it automatically switches to the island operation to ensure 72 hours of continuous power supply for critical loads. This feature is particularly popular in industrial areas of southern Italy where power outages are frequent, with a food processing plant using AK-PCS1-100K resulting in a 90 percent drop in production interruptions. - Flexible capacity expansion: standardized module design, single unit power coverage 50kW to 500kW (such as AK-PCS1-150K can be extended to 250K/500K models), through parallel technology easily adapt small convenience store rooftop power station (50kW) to large industrial park microgrid (5MW class). A logistics center in Rotterdam, the Netherlands initially deployed 1 150K equipment, gradually expanded to 5 parallel with the growth of electricity demand, with a capacity of 750kW, the whole process without downtime transformation, and the engineering cycle was reduced by 40%.
In terms of technical performance, ARK PCS builds competitive barriers with 97% peak efficiency (industry-leading level) and harsh environmental adaptability: - High performance conversion: The two-stage topology optimizes the power path, reduces conversion losses, and, combined with the forced air cooling system, maintains full power operation even at 45 ° C (conventional equipment is usually derated to 70%). In a PV + energy storage project in Barcelona, Spain, the annual comprehensive efficiency of PCS reached 96.2%, 3 percentage points higher than similar products, and the annual power generation increased by about 50,000 KWH. - All-scene protection: IP20 standard cabinet (IP54 outdoor type is optional) ADAPTS to indoor and outdoor environment, and has built-in transformer isolation technology to effectively resist harmonic interference of the power grid, with 12 protection functions such as over-temperature, over-voltage, under-voltage, reverse phase, and island effect. In the Polish winter -20℃ low temperature test, the equipment startup time is less than 10 seconds, and the continuous operation trouble-free time exceeds 100,000 hours, far exceeding the EU CE certification requirements. - Intelligent interconnection management: Standard 10.1-inch touch screen and RS485/CAN/Ethernet multi-communication interface, support Modbus, IEC 61850 and other mainstream protocols, seamless connection to the enterprise EMS system. An industrial park in Hamburg, Germany, through the ARK cloud platform, monitors the operating status of 15 PCS in real time, remotely adjusts the energy storage charging and discharging strategy, improves the demand-side response speed to 200ms, and is awarded the "grid-friendly user" certification.
Taking a machinery manufacturing park in Bavaria, Germany, as an example, its original power supply system relies on the municipal grid and natural gas generators, and faces the double pressure of electricity price fluctuations (peak electricity price exceeding 0.35 euros/KWH) and carbon emissions exceeding the standard. ARK's customized AK-PCS1-150K solution achieves energy efficiency in three steps: 1. Multi-energy access transformation: Access 2MWp photovoltaic array, 1.2MWh lithium battery pack, through the PV interface of PCS to achieve MPPT maximum power tracking, photovoltaic utilization rate increased from 82% to 95%; 2. Dynamic load scheduling: daytime PV priority direct supply production equipment (accounting for about 60% of the load), the remaining electricity is stored in the battery; At night, the batteries supply power to the grid through PCS inverter (charging during the low period of electricity price, discharging during the peak period), and cooperate with the peak-valley difference strategy of the grid, the annual electricity cost is reduced by 42%; 3. Enhanced emergency support: In off-grid mode, PCS can drive 50% of the critical load of the park to run for 12 hours, replacing the original diesel generator, reducing carbon emissions by 180 tons per year, and achieving the EU carbon emission reduction target three years in advance. The success of the project has verified the adaptability of ARK PCS in complex industrial scenarios, and its "plug and play" characteristics (installation cycle is only 7 days) and "zero commissioning cost" advantages have become the core attraction of small and medium-sized enterprises' energy transformation - without transforming the original distribution system, only standardized interfaces can realize the flexible interconnection of photovoltaic, energy storage and power grids.
From PCS to the ecological construction of energy Internet As the EU accelerates the integration of "renewable energy + energy storage", ARK is deepening technological innovation around three directions: - High voltage platform adaptation: Research and development of the next generation PCS supporting 1500V DC input, compatible with large ground power stations and energy storage containers, single-unit capacity increased to 1MW, to meet the needs of centralized micro-grid projects in Spain, France and other countries; - V2G and demand response: Combined with charging pile business, develop a "vehicle-pile-network-storage" collaborative system to realize bidirectional energy flow between electric vehicles and PCS. In the pilot project in Germany, a single electric vehicle can participate in grid peak regulation and provide 5kW reserve power; - Local service network: Set up technical service centers in Poland and Italy, reserve 100+ sets of spare parts, reduce response time to 4 hours, and cooperate with remote diagnosis system to ensure equipment availability rate of more than 99.5%. As of mid-2024, ARK PCS has been deployed in 8 EU countries, covering 200+ scenarios such as industrial and commercial parks, data centers, and agricultural greenhouses, with a cumulative conversion of more than 120 million KWH of electric energy and reducing 85,000 tons of CO₂ emissions. In the face of the EU microgrid market size is expected to reach 30 billion euros in 2030, ARK will be "hardware modular + software intelligent" two-wheel drive, become the core hub of "connecting renewable energy and users" in the energy transformation, helping the global industry and commerce to achieve the essence of "energy use" to "pipe energy" leap. In the wave of the energy revolution, the power conversion system is no longer a simple device, but the "heart" of the microgrid - it connects the "artery" of photovoltaic, the "blood" of energy storage and the "cells" of load, to build a self-consistent cycle of energy ecology. ARK PCS uses technology to solve energy efficiency problems, meets diverse needs with scenario-based innovation, and is working with European partners to write a new chapter in industrial and commercial energy transformation. When each PC becomes a node of the energy Internet, we believe that the blueprint of a zero-carbon future is gradually becoming clear in the modular stitching.
