The mppt controller plus 2 mono 150w panels (series connection 24×2=48v) charge the battery very good in cloudy weather, inverter under the load about 1,7kw water pump.
This video covers off the majority of my solar system setup. The inverter has been shifted since I videoed it a couple of months back and it is very difficult to get a good video of it now, so that and the DC busbar have not been shown. The rest of it though, warts and all, is in this video.
Yes, it isn’t all ideal. I know that. This is a long term project and it is as always a work in progress. As I save up money I buy things but I do not leave myself short as going hungry is a bad idea.
Hope you all enjoy the system overview!

Please be aware that these videos are based on my personal experiences, opinions and lessons learned, and are not going to work in every situation. I am not a solar installer or expert. I have learned many lessons from YouTube people as well as getting professional advice. If you do not know how electricity works, you should always seek out the services of a qualified electrician.
