Zhejiang Meishuo Electric Technology Co., Ltd. will participate in CPSE 2026, the China International Energy Storage & Charging Technology Exhibition, from November 25 to 27, 2026. Visitors are invited to meet the Meishuo team at Booth 1B35 and discuss relay solutions for new energy equipment, energy storage systems, EV charging infrastructure, PV inverters, UPS equipment and industrial control applications.
As electrification expands across transportation, renewable energy and industrial power management, component selection is becoming a system-level engineering decision. Relay performance affects how equipment manages switching, isolation, control signals and load connection throughout its operating cycle. For equipment manufacturers and system integrators, the right relay must be evaluated together with the application environment, switching duty, electrical load, installation space and long-term supply requirements.
At CPSE 2026, Meishuo will present a selection of relay solutions designed to support different power-control and interface requirements. The invitation materials highlight MPQ1, ME108, ME109 and ME106 as representative products for new energy and energy storage applications. Their application directions include PV inverters, UPS systems, EV chargers, APF equipment and industrial control.
New energy equipment often combines power conversion, monitoring, protection and communication in a compact architecture. A relay used in a control interface may have a different duty from a relay used for a higher-load switching function. The selection process therefore needs to begin with the complete electrical and mechanical context rather than with a single nominal current value.
Engineers typically need to review several factors together:
The coil voltage and the actual control signal provided by the system;
The load category, including resistive, inductive or mixed loads;
Steady-state current, inrush current and switching frequency;
Contact configuration, terminal arrangement and available PCB or panel space;
Insulation and isolation requirements within the equipment architecture;
Ambient temperature, enclosure conditions and expected service cycle;
Production continuity, approved alternatives and traceability requirements.
These considerations are especially important in PV inverters, UPS systems, charging equipment and energy storage applications. The relay is not an isolated component. It operates as part of a control path that may include a controller, driver circuit, protection components, sensors, contactors and a power-conversion stage. A technically suitable relay must therefore be matched to the whole switching task.
The Meishuo invitation identifies four relay products for visitors to review at the exhibition.
MPQ1 is presented as a relay with a 60A switching capability and 4kV insulation reference in the invitation materials. Its stated application directions include PV inverters, UPS systems and EV charging equipment. For engineers, the key discussion is how the relay's contact and insulation requirements align with the equipment's switching architecture and safety design.
ME108 is presented as a dual-group high-power PCB relay with a 35A, 277VAC reference in the invitation. Its application directions include PV inverters, UPS systems, EV chargers and APF equipment. This type of product can be relevant where control density, PCB integration and channel arrangement must be considered together.
ME109 is highlighted for high load capacity, with a maximum 50A reference and various contact-gap options shown in the invitation. It is positioned for PV inverter and UPS applications. Contact configuration and switching duty should be reviewed against the system's load type and operating cycle before final approval.
ME106 is presented with a 32A switching capability and multiple contact-gap options for new energy and industrial control. Its application value depends on the required isolation, load behaviour, installation structure and control interface of the target equipment.
The figures above are taken from the supplied Meishuo exhibition invitation. Final product selection should always be confirmed against the current datasheet, application conditions and validation requirements for the customer's equipment.
CPSE 2026 provides an opportunity to move beyond catalogue comparison and discuss the practical requirements of relay integration. Visitors can bring questions about coil control, contact loading, PCB layout, terminal spacing, contact gaps, operating cycles, alternative product evaluation and production ramp-up.
For OEMs developing charging equipment, inverters, UPS systems or energy storage control units, an early relay review can reduce redesign risk. A structured review should cover the electrical load, control circuit, mechanical envelope, thermal environment and required validation plan. It should also distinguish between a prototype selection and a production-approved component strategy.
Meishuo's engineering discussion is intended to help customers connect these requirements with suitable relay structures and application scenarios. The goal is not simply to select a part number, but to establish a reliable switching solution that can be evaluated, documented and maintained throughout the product lifecycle.
Meishuo welcomes EV charging equipment manufacturers, energy storage system developers, PV inverter suppliers, UPS manufacturers, industrial automation companies, distributors and engineering teams to visit Booth 1B35 during CPSE 2026, November 25–27, 2026.
Visitors who would like to discuss a relay application in advance can prepare the following information:
Control voltage and control-signal conditions;
Load type, operating current and inrush characteristics;
Switching frequency and expected service cycle;
Contact configuration and insulation requirements;
PCB, panel or enclosure constraints;
Target market, validation plan and production schedule.
With these details, the discussion can move directly toward application matching and engineering evaluation. Meishuo looks forward to meeting industry professionals at CPSE 2026 and exploring reliable relay solutions for the next generation of electrified equipment.
