Mora AESPV32 ELR1 Solar PV DC Isolator Switch 32A

The Mora AESPV32 ELR1 Solar PV DC Isolator Switch is a 32A rotary disconnect designed for compatible photovoltaic array circuits. It provides a local means of isolating DC conductors between a solar array and inverter when correctly selected, wired and installed.

The enclosed design is listed with IP66 protection, making it suitable for appropriately positioned outdoor solar installations. Its four-pole configuration can be used for a compatible double-string arrangement, but the exact pole wiring must follow the product diagram and the solar system design. A qualified solar electrician should confirm voltage, current, polarity and cable requirements before installation.

• Designed for PV array and inverter DC-side isolation
• Compact solution for residential and commercial solar projects

Product Specifications

The maximum system voltage and current must be calculated from the solar modules and expected site conditions. Cold weather can increase PV open-circuit voltage, while irradiance and design factors affect current. Never select an isolator using inverter size alone.

What a Solar DC Isolator Does

A DC isolator provides a mechanical disconnection point for planned inspection, servicing and emergency procedures. It helps separate a section of the DC circuit when operated according to the system design. Solar modules continue generating electricity whenever exposed to light, so switching the isolator off does not make the array-side cables or terminals safe to touch.

This isolator is not a circuit breaker and should not be described as providing over-current or short-circuit protection unless the exact product documentation confirms those functions. Solar fuses, DC breakers and surge protection may still be required.

Suitable Applications

• Residential rooftop PV installations
• Commercial solar arrays
• Compatible dual-string or dual-MPPT arrangements
• Hybrid and off-grid solar systems
• Outdoor inverter and array isolation points

IP66 Installation Considerations

An IP66 enclosure rating depends on correct cable glands, lid sealing, mounting orientation and installation workmanship. Unused entries must be sealed, and cables should be supported so water cannot track into the enclosure. UV exposure, heat, standing water and direct weather conditions should be considered when selecting the mounting location.

Do not claim weather resistance if holes, glands or seals have been modified incorrectly. Periodic inspection should check the enclosure, handle, glands, terminals and signs of heating or moisture.

Solar DC Safety Guidance

DC switching requires equipment specifically rated for the circuit voltage, current and polarity. Using an AC-only switch on a PV circuit can create dangerous arcing. The installer must follow the wiring diagram and ensure all poles open as intended.

Installation and maintenance must be performed by a qualified solar electrician using appropriate DC-rated tools, test equipment and personal protective equipment. Confirm polarity before connection, tighten terminals to the specified torque and label the isolator clearly. Do not operate or open damaged equipment.

Complete Protection Coordination

The isolator is not a replacement for DC fuses or circuit breakers, a dedicated solar surge protection device, proper earthing, cable protection or inverter isolation procedures. The complete system should be designed so every component is rated for the maximum possible DC conditions.

Buying Checklist

• Calculate maximum string open-circuit voltage at minimum temperature
• Calculate maximum string current with the required design factor
• Confirm the number of strings and pole arrangement
• Verify cable size, gland size and connector compatibility
• Confirm the unit label and wiring diagram before installation

Mora AESPV32 ELR1 Solar PV DC Isolator Switch FAQs

Does switching the isolator OFF make solar cables safe?

No. Solar modules continue producing DC voltage in daylight. The Mora AESPV32 ELR1 Solar PV DC Isolator Switch disconnects the intended circuit section only when correctly wired; array-side conductors may remain live.

Can this isolator be used for every 1000V solar system?

No. The actual unit label, maximum PV open-circuit voltage at minimum temperature, string current, utilization category, pole arrangement and manufacturer wiring diagram must all match the installation.

What is required to maintain the IP66 rating?

Use correctly sized weatherproof cable glands, preserve the lid seal, close unused entries and mount the enclosure in the approved orientation. Poor drilling, damaged seals or unsuitable glands can reduce protection.

Who should install this solar DC isolator?

A qualified solar electrician should install and test the Mora AESPV32 ELR1 Solar PV DC Isolator Switch. For photovoltaic equipment and electrical-safety standards, consult the International Electrotechnical Commission and follow applicable Pakistani requirements.
