Solar Installer Range
Bright solutions
IMO is at the forefront of control component technology specifically developed for the renewable energy market and in particular solar energy. Whether meeting the demands of safe and efficient DC switching or delivering solutions that help to maximise solar energy conversion rates, you can be sure that IMO products have been developed to meet the highest technical and commercial standards. Our carefully selected range of Solar products have been brought together, to provide today’s solar installer with the products they require to keep Solar safe on all their installations.
Specifically developed for arduous DC disconnect applications, the IMO range of Solar Isolators features an operator independent trigger ratchet switching mechanism resulting in switching times of less than 5ms. High reliability knife edge contacts and long arc cooling chambers ensure safe and effective isolation of DC voltages within solar installations.
IMO’s range of mobile connectors are used to connect PV panels in series. They also link between lengths of cabling and allow connection to Branch and Panel connectors. Branch connectors are used to link multiple strings together allowing, for example, a 2 pole (single string) DC isolator to switch both strings at the same time removing the need to use 2 isolators. Panel connectors mount on solar string boxes, enclosed DC isolators and any other enclosed DC switching device allowing easy connection to the rest of the PV system.
Available in 2 to 8 pole versions in a wide variety of mounting and handle configurations, the IMO Solar Isolator range is suitable for most OEM or site installation applications.
IMO’s range of enclosed IP65 rated AC isolators includes 3 to 8 pole versions rated from from 20A to 80A. The design also includes an interlocked enclosure lid and 3 padlockable positions for safety.
Safety! The IMO SI is a True DC switch not an AC version de-rated or re-wired for DC operation. Features include: Operator independent switching mechanism High speed trigger ratchet switching (5ms max) IP65 rated enclosure with top and bottom M25/M20/M16/M12 push outs and rear cable entry Fully enclosed internal switch without additional wiring for maximum safety Knife edge contacts and arc cooling chambers High reliability rotary snap action mechanism Maximum 1Nm torque for easy operation Compact space saving design 16mm2 box terminals for easy wiring
WARNING
The IMO SI range has a switching speed that is independent of the operator. The mechanism is such that there is no direct linkage between the operator handle and the switch contacts. As the handle is moved it interacts with a spring mechanism which, upon reaching a set point, causes all the contacts to “SNAP” over thereby ensuring a very fast break/make action which means that the arcs produced by the constant DC load are normally extinguished within 5ms. Many alternative solutions, particularly those based upon AC isolator design, have a switching speed that is directly linked to operator speed. Slow operation of the handle results in slow separation of the contacts and can produce arcing times of 100ms or more. The SI range also features a “knife edge” mechanism so that when the unit is operated there is a double break on each pole with arcing effect occuring on the corners of the switch only. The main contact is made on an area where no arcing has occurred. The rotary nature of the contact mechanism also means that when the SI is operated a self-cleaning action occurs on the arcing points, thereby producing good contact integrity over the life of the product. A secondary advantage of this type of operation in photovoltaic applications is that, in the event of a supply to earth failure, the short circuit current pulls the contacts together thereby giving an extremely high short circuit current capability in the order of up to 1700A (product dependant). Completing the package for all your PV instalation requirements is the IMO range of Solar Connectors. Rated up to 1000V 30A for 2.5-6mm2 cables, the IMO connectors feature a secure easy clip and release system providing the installer with a time saving and efficient connector solution. As with all IMO PV products the connectors have been tested to the highest standards and come rated with IP67 protection, UL-94-5VA fire resistance and provide class 2 protection.
