One of the most common problems found with the operation of a solar PV system is the inadequate connection of MC4 connectors. This is usually an issue with the crimping quality of the connectors, but this can be addressed by the new tool released by Test Instrument Solutions, in conjunction with hand-held tools giant KNIPEX – the new TIS MC4KIT.
What are MC4 connectors and why are they important?
MC4 connectors are also known as solar connectors. They are very small components, but also very important, and are needed in junction boxes, inverters and for cable connections between components. The problem that can occur is that the connector can burnout, this can be due to the poor quality of the connector itself, ie. the component, or most commonly it is caused by poor installation. The installation issue is usually down to crimping quality.
The main purpose of MC4 connectors is to optimise the solar PV system performance, but they are also important in safeguarding the components of the system and ensuring safety during the installation and maintenance process. However, if you cause damage to the MC4 connectors through incorrect crimping, this can cause electric arcing and therefore presents a fire risk and a potential safety hazard to anyone in contact with the installation. In addition to the risk of arcing, poor crimping quality can also lead to reduced efficiency in the solar PV system and excessive wear and tear.
The importance of using quality crimping tools
So using the correct crimping tools during the installation process of the MC4 connectors makes this connection process more efficient, safe and compliant. A good crimping quality ensures a proper and secure connection and minimises the risk of loose or faulty connections, which could compromise the system efficiency. The connection of the MC4 connectors has to be secure, with no visible damage or deformities, and this can be achieved by using the new TIS MC4KIT.
The new TISMC4KIT comprises of a set of crimp system pliers for exchangeable crimping dies with multi-component grips, a set of mounting tools for solar cable connectors, a crimping die for solar cable connectors and a locator for the MC4 connectors. Designed and created in conjunction with the high quality tools manufacturer KNIPEX, the kit comes in a red, branded box for ease of transportation and storage.
