How To Install A single Phase Inverter

Let us take a 3.5 kva inverter installation for an example.

• Run A cable that will run from the Distribution Board of the building to the secondary Distribution Board that you installed for the inverter(in order to put in in Bypass mode if the machine has a problem) and also to the breaker. The cable is usually a three in one cable which will be labelled as the input(it charges the inverter), the output(it supplies the load) and the neutral.
• Assuming that there is a change over(learn how to install a change over here) before the distribution board in a building which switches between the mains and a generator; the out put of the change over usually has four wires consisting of three live wires and a neutral. So the three wires enter into the three holes in the distribution board and the last neutral wire goes where it is meant to be( learn more about a distribution board here)
• You should have already prepared the trunking which will conceal the cable connections and make your work look neat and perfect
• Now to distinguish the wires; the wire that is going to supply the loads on the inverter i.e the output will be inserted in one of the holes of the DB and all the lines associated with that particular hole or channel will only carry the loads that want to be on the inverter, or better still, after the load separation join the cable of the loads that you want to be on the inverter together and  attach them to the output cable. It is advisable to use a papertape to label the wires.
• The second wire that serves as the input will now be put in any other hole or channel of the DB, and it will be connected straight to a breaker (learn more about the materials needed for the installation of an inverter); from the breaker to the input of the inverter There are usually labels behind the inverter that lets us know which terminal to connect the wires to. The function of the breaker is to allow or disallow charging the inverter batteries.
• The Last Wire is connected to the respective neutral terminals both at the back of the inverter and at the distribution board.
• Now the last but not the least step in to connect the neutral and output wire through the second change over  to the inverter, it is usually labeled "bypass" vs "inverter". As far as the inverter does not have a problem, the secondary change over should always be on inverter mode.
