Every feature below addresses one of the pains above — not with a spec sheet claim, but with field-validated control engineering.
Virtual Synchronous Generator control establishes voltage and frequency from the battery side — no reliance on an external reference. Supports black start, seamless on/off-grid transfer in <20 ms, and stable multi-unit paralleling without communication wiring.
Each phase is commanded independently — active and reactive power set separately per phase. Supports 100% unbalanced loads at full rated power, eliminating the “lowest phase wins” derate that cripples symmetric PCS under zero-export rules.
Virtual impedance and adaptive damping stabilize against grid THDu up to 30%. Output THDi stays under 3% regardless of input conditions. Rides through voltage sags down to 0.1 p.u. and frequency swings of ±5 Hz.
Designed for integration into protected C&I energy storage cabinets, the EPCS105/125-AM(-F) features an IP20 enclosure and intelligent forced-air cooling. It operates from –30 °C to +55 °C, with output power derating above +45 °C. Its modular three-level architecture supports flexible cabinet and system integration.
Organized the way engineers actually read datasheets — input first, output next, grid compliance, protection, physical, environment, and certification last.

This PCS isn’t just a box. It’s the core module of a modular system where you combine PCS, STS, and DCDC to build whatever scale of project you’re delivering — from a single cabinet to a megawatt-class container array.
The PCS and STS modules can communicate directly with each other—no protocol adapter is needed, enabling automatic on/offline switching. Therefore, combining them is a configuration process, not an integration. PCS, STS, and EMS can all be connected to the EMS, making them suitable for various application scenarios.
Enjoypowers can provide the Modbus TCP/RTU communication protocol for these core modules for control by third-party EMS providers.
Combine the three modules into the cabinet topology your project needs. Two standard configurations cover >80% of C&I deployments; fully custom builds are available for the rest.
4 × 125 kW PCS modules in parallel. 500 kW per cabinet. For peak shaving, capacity expansion, and VPP participation.
PCS + DCDC + STS in one cabinet. Solar input, battery storage, and on/off-grid transfer in a single footprint. Minimum floor space, minimum field wiring.
Stack cabinets inside a standardized 20-ft or 40-ft container and you have a site-ready, transportable MW-class building block. Up to 12 PCS modules per container. Units coordinate via VSG without site-level control wiring.
Need a non-standard layout? We build project-specific cabinets from the same module pool — no custom firmware required.
Commissioned at our Shenzhen facility, shipped as a complete pre-tested unit, installed on site in under three days.
To meet the strict standards of the Australian Clean Energy Council (CEC), we provide all necessary technical documentation and compliance certificates for our Power Conversion Systems (PCS).

From procurement shortlists to commissioning — the ten questions we hear most often during technical due diligence.
Up to 12 units under VSG grid-forming control. The virtual synchronous generator algorithm uses grid-side voltage and frequency as the shared reference — units coordinate their power sharing through physics, not messages. This eliminates the single point of failure inherent in communication-based master-slave architectures.
For installations above 12 units, we recommend our EMS as an upper-level coordinator for SOC balancing and energy optimization, not for real-time control. Real-time grid support remains VSG-based.
Yes. The PCS can establish a microgrid from zero with no external power reference, starting from stored battery energy. Typical black-start sequence completes in under 3 seconds, with load pickup controlled via inrush-limited ramp. Works standalone or in parallel — in a multi-unit cluster, a single master unit starts first and the remaining units sync in under 500 ms.
The PCS handles 2× rated current for 10 seconds and 3× rated current for 100 ms — enough to ride through most DOL motor starts up to roughly 30% of rated PCS capacity without tripping. For hard-start loads beyond that envelope, parallel operation distributes the surge across multiple units, which is one of the key benefits of the multi-unit topology.
Yes. All three module types share the same firmware layer and communicate natively with the Enjoypowers EMS — no protocol adapters, no separate controllers, no site-level coordination logic to custom-build. This is the whole reason the “one-cabinet microgrid” configuration works: drop in a PCS + DCDC + STS combination, apply power, and the EMS discovers and orchestrates them automatically.
LFP and NMC are supported natively with pre-configured charge profiles. Sodium-ion support is available with a firmware selection — we’ve validated with several sodium-ion battery vendors and can share the specific test reports during pre-sales discussion.
BMS communication supports CAN 2.0B and Modbus RTU. We maintain a compatibility list of battery brands (CATL, BYD, Pylontech, EVE, among others) — ask sales for the latest version.
The PCS maintains stable operation up to THDu 30% on the grid side. Virtual impedance control decouples the output current regulator from grid voltage harmonics, so output THDi stays under 3% regardless of incoming distortion. This is directly inherited from our power quality product line, where harmonic immunity is table stakes.
Under 20 ms with our dedicated STS module. This is fast enough to hold loads that require IEC 62040-3 Class 1 UPS-grade transfer (computers, lighting, most variable-speed drives). Without an STS, transfer uses the PCS’s internal contactor at approximately 100 ms, which is still fine for thermal loads and most industrial equipment.
IP66 enclosure with C5 anti-corrosion coating — deployable in coastal, industrial, and high-humidity environments without additional protection. Full power operation from –30 °C to +50 °C ambient. Above +50 °C the unit derates linearly; thermal protection is guaranteed up to +60 °C.
Altitude: full power up to 3000 m, derated above. For desert or high-altitude projects (tropical coasts, Andes, Himalayas), we have field references — ask for location-specific deployment data.
Factory-configurable to VDE-AR-N 4110, G99, EN 50549, UTE C15-712, CEI 0-21, AS/NZS 4777.2, and NRS 097-2-1 among others. The grid profile is a firmware setting, not a hardware variant — one SKU covers all markets. LVRT/HVRT, frequency response, and reactive power curves update when the profile is selected.
Standard warranty is 1 years, extendable to 5years. Support is delivered through a network of regional service partners in 70+ countries, backed by our Shenzhen engineering team for Tier-2 escalations. Remote diagnostics are included via our EMS; spare-part availability is within 7 days for most regions.
