In today’s era of pursuing sustainable development and smart homes, an increasing number of villa owners are integrating photovoltaic systems with traditional grid power to achieve efficient and reliable energy supply. As a professional manufacturer of electrical protection and control equipment, GEYA is committed to providing high-quality products to help customers build safe and intelligent power systems. Today, we share a real-world case study from Sri Lanka: in a high-end villa, GEYA’s products were successfully applied to both grid and photovoltaic systems, ensuring the stability and safety of the power supply. Let’s dive into the details of this case.
Customer Background: A Villa Owner Embracing Green Living
The client, a villa owner passionate about sustainability and technology, resides in a modern suburban villa in Sri Lanka. To reduce reliance on the traditional grid, he opted to install a photovoltaic (PV) system. After thorough evaluation, he selected GEYA’s products for their proven reliability, ease of installation, and long lifespan. The system was divided into two main modules: the grid power system and the photovoltaic system, seamlessly integrating traditional and renewable energy sources.
System 1: Grid Power System – The Reliable Guardian of Household Distribution
The villa’s grid power system forms the foundation of its electricity supply, channeling power from the grid to various areas of the home. The client installed a standard household distribution box, including a utility meter, molded case circuit breaker (MCCB), recloser, and miniature circuit breaker (MCB). GEYA’s recloser and circuit breaker played pivotal roles in this setup.
- GEYA GRD9L-R Automatic Recloser: The GEYA GRD9L-R automatic recloser is an intelligent electrical protection device designed for household grid applications, paired with the GYL9 residual current device (RCD) in this case. Its core function is to automatically reclose the circuit when the GYL9 RCD trips due to faults (e.g., leakage), eliminating the need for manual intervention. This significantly reduces maintenance costs and ensures rapid power restoration, enhancing household power reliability and convenience. The GRD9L-R features three reclosing attempts; if abnormal tripping persists after three attempts, it sends an alarm signal via an auxiliary contact to alert the user to potential issues. The device supports manual/automatic mode switching, incorporates mechanical/electronic dual-locking for safe and stable operation, and uses LED indicators for easy status monitoring. It’s an ideal choice for building smart, safe household electrical systems.
- GEYA GYM9H Miniature Circuit Breaker: The GEYA GYM9H MCB is a high-quality electrical protection device tailored for household applications, widely used for overload, short-circuit, and isolation protection in residential settings. It ensures safe and stable operation of the household electrical system with efficient overload and short-circuit protection, as well as circuit isolation. Compliant with IEC/EN60898-1 and GB10963.1 standards, the GYM9H supports a wiring capacity of up to 25mm² and dual busbar connections for easy installation and maintenance. Its transparent labeling and contact position indication enhance user convenience and safety. With a compact design and a high breaking capacity of up to 10kA, the GYM9H is ideal for protecting single-phase circuits for household lighting and small appliances.
System 2: Photovoltaic System – The Smart Core of Green Energy with Seamless Switching
To achieve sustainability, the client installed solar panels and an inverter on the villa’s rooftop, creating a complete photovoltaic (PV) system. This system operates in parallel with the grid but requires stable switching between power sources. GEYA’s automatic transfer switch (ATS) and over/under-voltage protector excelled in this role.
- GEYA W2R PC-Class Automatic Transfer Switch (ATS): The W2R ATS enables seamless switching between grid and photovoltaic power. When solar generation is sufficient, the ATS prioritizes solar energy; during over/under-voltage conditions in the PV system, it instantly switches back to the grid, preventing power interruptions. With a 50ms response time and compatibility with both inverter and grid inputs, the GEYA W2R ATS ensures uninterrupted power for the villa’s air conditioning, lighting, and appliances.
- GEYA GPS8-02 Digital Voltage and Current Protector: The PV system is prone to voltage fluctuations, and the GPS8-02 protector monitors anomalies (e.g., over or under-voltage) and disconnects the circuit to prevent equipment damage. It supports true RMS voltage measurement with a digital display for voltage and current, offering ≤1% measurement accuracy. Fault statuses are shown via LED indicators. The device allows customizable over/under-voltage and overcurrent settings for enhanced protection and uses a dual busbar design for improved wiring capacity. It’s easy to install on a 35mm standard rail.
In the client’s PV system, these GEYA products formed an efficient protection network. Solar panels capture sunlight, the inverter converts it into usable power, and GEYA’s devices ensure safe and reliable operation.
