Zero‑Carbon Farm – Save up to 60% on your electricity bill

• Solar + battery energy storage system = your own power plant on the farm
• Clean energy source
• Significantly lower electricity costs
• Expand grid capacity (no more overloaded transformers)

Product overview
The ESS-ACDC-125-WPG is an integrated hybrid PCS combining photovoltaic input, energy storage battery interface and optional diesel generator support. Designed for industrial applications, it provides multi-port intelligent energy dispatching with PV-first, peak shaving and valley filling strategies, hybrid multi-source supply and storage-backed backup. The unit supports wide voltage/frequency ranges and intelligent off-grid switching to ensure continuous supply for critical loads.

Key features

• Integrated hybrid PCS: PV, battery and diesel interfaces in a single cabinet for simplified system architecture.
• Flexible installation: compact, side-by-side installation for space-efficient deployment.
• Modular scalability: scalable parallel connection — up to 4 units in off-grid mode and up to 8 units in grid-connected mode.
• Advanced energy management: multi-port intelligent dispatch, PV-priority operation, peak shaving and valley filling.
• High performance: up to 97.5% max efficiency, low THDi/THDu and adjustable power factor for improved system performance.
• Diesel & STS support (optional): diesel generator input and STS (static transfer switch) options for backup and transfer functions.
• Wide operating range: IP55 protection, corrosion class C3 (optional C4/C5), operating temperature -30°C to +60°C and altitude up to 4000 m (derating >2000 m).
