RE: Solar Electrical Learning Part-21||Week-21||Step by Step Troubleshooting of On Grid Solar Inverter(1.5 KW) in our office.
Good job on the cleaning aspect!
I just got a report today about a 5KVA system of someone. He complained that his panels were no longer charging the batteries properly.
I was suspecting two things.., it's either rats have destroyed his DC cables 😀 because he has stubborn rats in that environment or there is a breach in the connections.
I asked him to send me the pictures of the panels since it was accessible..., he did.
The whole panels were covered with dirts...
I advised him on what to do (cleaning), I sent two of my friends who are also installers..., they went there for the job. Now the panels are charging well. That's the feedback from him this evening.
Many people neglect this part, but it's very important.
The output voltage was 206 volts DC
Was that from a panel or the entire panels?
Does your systerm have a battery back-up?
Dear Sir,
Our company is manufacturing rod. Rods are produced through various processes from melting iron to making billets. So here a lot of iron powder along with the smoke gets blown over the solar panel.
The output voltage of all panels is 206 volts.
Yes, I have battery backup.
When the grid power supply is off, the 33 kV high voltage tripping devices are kept on through battery backup.
Dirt and bird droppings reduce the output of solar panels.
Now I understand where the dirt is from.
Much clear
Dear Sir,
There is an electrical panel that converts the DC voltage from the battery to 110 volts DC and sends it to the tripping device. 110 volts is converted through the panel in the picture below.
In the figure below, the tripping devices of 33 kV high voltage line are operational at 110 voltage. It is very important to keep the tripping device functional on high voltage lines.
Thank you so much for reading my post and leaving a nice comment.
