5kw Ongrid Solar Rooftop Installation


Now this is a five kilowatt system consisting of 16 panel. Here is a positive wire of one of the panels, which I have labeled it with a red tape. This is an MC for connector, so the other wire is connected in series with the other panels.

On the structure you can see, you know are in series connected knowledge into second row, and the wire goes like this and series and comes back from here so now here I have a negative end, which is a negative female mc4 connectors.

So I have two connector one positive and one negative on the structure which will be going down towards de inverter. So here I have PVC based plastic pipe one inch just die of the pipe which is going down from here safely.

It’s under the sort of baby, so there is no chance of water entering the spikes which completely safe and insulated. Here is the inverter mounted. You can pause the video and have a look at the specification of this inverted siglo, watt, inverter and see model number and other technical electrical specification is given and from here we have connected that single array to this inverter to one of the MVP t at a 16 panel connected in series: this is the DT box consisting of the DT fuse.

Normally, there is an output port is connected with a converter and you can see the positive and the label or the red tape. So there is no chance of confusion. This is the thousand volt at a glance DC fuse, and the negative pole is here.

This is a switch or you can call it a DC. Mcb or a regulator is a input, positive and negative port which will be connected later on. You can see. The labeling is here: output port, an input port from the DC box.

So these are the input force which will be connected from the solar panel, and here is the board for three-phase wire, which I am going to connect it now with the AC box over here. Now two wires are coming from the solar panels.

Positive and negative is connected with the DC fuse here, the positive and here the negative one, just deciphered. So now it’s, going down towards the DC surge additive. Here’s, the DT surge arrester same way.

We have the grounding wire homes so jealous to going towards the easy box. We’ll. Do the common grounding for these devices in case of extra voltage? It will be tripped so that all the other devices are safe.

It’s now time to turn it on now. The power from here is going inside the inverter. Now we’ll turn on the inverter to see if it’s working on solar power or not. Okay, now the inverter has started and see the model number of the inverter.

This now the status is a red kind of fault, because it is not connected with the grid. That is why it is not generating because of the and Iceland. In effect, what happens in this effect is when there is no power in the grid in water.

The solar PV inverter is not supposed to inject the power, otherwise the extra power generator from the PV will be directly injected into the grid, and there will be a it means. The power will be flowing to the houses, residential house is nearby and the load is not as such suppose the system total bond.

So in order to safe guard the system just anti-ice landing effectively. Me is here’s. The AC box is the 4 pole, 32 M and C B. So you can see there. There is no power just because of that ice landing effect.

So we’ll turn it off. We go three-phase wire connected from the inverter ryb and the neutral going now I’ll check the voltage, whether it is there or not. So there is no AC voltage right here, because then what is not injecting any DC current right now, since there is no current in the grid now I will check the DC voltage.

Okay, oh right! Now these it’s only AC mode. Let me turn it on the DC thousand volt DC. Now we’ll set the DC’s; none but Elmo; okay, now it’s in the DC mode, so it’s. Six hundred and thirteen fourteen volts in a series of sixteen panels that is 315 wah what each so the inverter is operating safely.

Now I explained with the single line diagram from the PV panels. The power is going to the DC fuse towards the grid-tie inverter, where the DC is converted into AC and finally, to the solar meter, which shows that how much you see that you have generated from the solar PV, then it goes to a consumer distribution panel from Where the load is connected and the extra power generator from the grid goes towards this net meter tour and is injected into the government’ll in case the load require extra power that comes from the bi-directional meter to the district distribution panel.

So the bi-directional meter shows both whatever you have imported and whatever even exported, so the electricity bill is modified. According to that in case, you are exporting more in the electricity bill that obviously go down.

So this is how this is a net metering system, that’s, how it works, and in case you have a doubt in this system, you can click on the link below on my blog and you get the complete detail of this project as to What are the specification of single single modules and whatever required to develop all these? So the yellow meter is the existing meter in this diagram, which will be used as a solar meter just to show whatever is produced from the solar PV and the green color meter is a net me.
