Apologies if I sound harsh but to DIY properly you have to equip yourself with the right information and tools. You can't *just choose one of the sides* - your panels ideally should be facing South and if South is not available then West or perhaps East and the ideal tilt/angle should be tending towards nearly flat in this side of the world. Please download a compass app on yoir phone and determine where your South is and relocate your panels to this direction. After getting the panel orientation right, please look to your cable gauge - you should be doing minimum 6mm at ~150v - I use 10mm as my minimum gauge - the thicker your cables the better Next check each panel to be sure it is delivering voltage and amps properly and make sure your panel to panel connections are tight. Finally please remove the SPD and see if situation improves - some SPDs malfunction or are miscalibrated and start shunting away power at too low of a voltage. It is possible also that your SPD is designed for a lower voltage application than you are using it for although I never studied the spec sheet you posted a while back. This are some preliminary checks you could do - you want to identify the root cause of your issues before applying any fixes or spending any money so that you don't throw good money away. ojeysky: 3 Likes |

ojeysky:Turn the load side off. Turn the AC out off. Does it do the same. As for zero watts your mppt on the inverter could be bad. It worked since you added the extra panels. Double check your connections if they are fine suspect the controller. If you have a spare controller test my theory. An breaker between the controller and the PV is a must. Turn everything off. Turn the PV off. Let the inverter power down. Then turn the inverter on and then the PV. See if the controller wakes up. We have blown à few controllers up connecting directly. We removed the batteries with the PV connected and we got a firework show. 2 Likes |

Hi guys. I have 8 panels of 300watts each, 4 batteries (12volts each) of 200amps each and a 5.5 kva inverter. Can I increase the number of batteries to 6? |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 1:16pm On Jul 07, 2019 |
ojeysky: ojeysky, the bolded explains why you initially got a high output on your panels in the morning and it later declined as the day went by. the sun rises in the east and sets in the west (every solar enthusiast should know this). by midday, the sun is directly overhead and after that it moves away heading west. if you have your panels facing east, you are more likely to experience reduced output anytime after midday. for my own installation, i have my third array facing east but it was a deliberate choice. firstly, my south facing roof space was maxed out and secondly, i wanted to take advantage of the early morning sun whenever possible. besides, i use stand alone charge controllers on all my strings so that voltage drop on one string doesn't affect the others... 3 Likes |

GeorgeD1: Sure at least that am aware of, actually if I had gotten above quite high output I would not have bothered much but like I said, highest I have gotten thus far is 450w. I am just waiting to get a few bucks to get the alone up and running for now I will live with the low output |

NiyiOmoIyunade: Lesson learnt and sure no offense at all it's fine to be harsh to get words out. Wish you were close to my location, would have invited you instead. Please download a compass app on yoir phone and determine where your South is and relocate your panels to this direction. I am using solarCT app though the app is suggesting that I tilt towards the North I will follow your suggestion. After getting the panel orientation right, please look to your cable gauge - you should be doing minimum 6mm at ~150v - I use 10mm as my minimum gauge - the thicker your cables the better Actually I made sure to use a good cable; it's a 2 core 10mm amoured solar cable Next check each panel to be sure it is delivering voltage and amps properly and make sure your panel to panel connections are tight. I will like to do this when I bring down the panels, but can I do the checks with a multimeter? What should I be looking out for? Finally please remove the SPD and see if situation improves - some SPDs malfunction or are miscalibrated and start shunting away power at too low of a voltage. It is possible also that your SPD is designed for a lower voltage application than you are using it for although I never studied the spec sheet you posted a while back. I have not even installed the SPD, waiting for my DC breaker to arrive before installing both. This are some preliminary checks you could do - you want to identify the root cause of your issues before applying any fixes or spending any money so that you don't throw good money away. Thanks a lot my brother, really appreciate the support and I hope this will be a great testimony for me eventually. PS: Just in case this has any meaning; today PV input voltage got as high as 197v but then it will sharply go back down to 160v or 150v at times. Perhaps this is due to the shadow thing

harizonal123: .. are you sure you're a Nigerian? lol Alaba is a place in Lagos; where you can even see a re-branded version of yourself. Lwkmd4h. Anyways, for 90k, look for Mpower Battery. it's a Chinese battery, but a good one. They're usually my low-end battery spec (my high end being Exide, Quanta) I have about 5 clients using Mpower for 2 years plus now and another 2 going for 2years Try and get it from Airwaves Ltd; they're the main distributors I know. Another good low-budget option for you is Safepower (Indian) @103k Cheers 5 Likes |

If you have a DC clamp meter you can do a quick test on the roof without taking any panels down. First eliminate mains or gen and run off solar and batteries and place a decent load on your inverter. Go up on the roof, set your multimeter to read DC amps and clamp around each panel cable in your string - each panel should be putting out thesame amps as the others in the string e.g with 18amps from the main PV to CC cable, each panel in your setup should be putting out about 3 amps each when you measure around the panel cables - if you see any panel reading close to zero amps or less than the others, first check that the cable connections are secure and if after ensuring a proper connection things do not improve, then such is a suspect panel that should be taken down for further testing. ojeysky: 2 Likes |
