mustaphagreens: If the CC is truly MPPT, check the specs to see if it can take the voltages of the panels connected in series, then connect them in series. This may be the solution to your problem. When I didn't know much about CCs, I once had a similar problem and I was corrected here and got better results. 1 Like |

mustaphagreens: Do you have a DC clamp meter? Fluke, etc Are they new panels? What brand and specs? Have you checked voltage from the panels? You should get the full voltage reading 36/38/41v if they are well positioned 1 Like |

mustaphagreens:u may have to check your settings and read input voltage from your panels too, 30v from a supposed 350w panel is totally off. dont return the cc yet, i just researched, it looks like it has heat sink underneath and it is sold for 45k too. 1 Like |
Re: Solar Energy, A Complement To FTA by mustaphagreens(m): 7:55pm On Dec 16, 2021 |
gadgetplanetng: Yes, they are new panels. The max voltage from the panels is 31v (I get 28v/29v/30v/31v). I don't have a DC clamp meter but I can get one. I didn't even note the brand and it's hard to check now that they are on the roof. I will call the engineer that installed them and provide more details tomorrow. |

mustaphagreens: while your charge controller may not really be the best for the job, i think you have to also look at other factors like panel orientation, cable size and distance. all this can contribute to your issues. besides, you didn't mention whether inverter is being used during the day simultaneously while battery is being charged. 1 Like |
Re: Solar Energy, A Complement To FTA by mustaphagreens(m): 8:07pm On Dec 16, 2021 |
Valto: The input from the panels never exceeds 31v. Sometimes, 28v, 29v, 30v. At this point, I am just confused. |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 8:09pm On Dec 16, 2021 |
mustaphagreens: Check the settings of the CC, i hope its set properly..bulk should be 15v or 14.8v...float should be 13.8v... 350w panel should produce above 31v,. Whats the Voc of the mppt cc?. If you dont know..send a picture of the specs.it shud b on the side or manual.. Powmr cc is a tried and tested cc, someone listed it for 50k sometime ago. If you can return this ur cc.do so and get the powmr....meanwhile confirm its set properly and send the spec sheet, so we can be on same page 2 Likes |

IYGEAL: The CC's PV max is 90v. If a series connection fixed yours, then, I will try that. See that attached picture

Re: Solar Energy, A Complement To FTA by gadgetplanetng: 8:16pm On Dec 16, 2021 |
mustaphagreens: Mine get the max voltage immediately there's a little sun so there might be an issue with position/angle. Also the factors like wire thickness and co GeorgeD1 mentioned might also come to play. 1 Like |
Re: Solar Energy, A Complement To FTA by IYGEAL(m): 8:24pm On Dec 16, 2021 |
mustaphagreens: Okay. With these specs, connect them in series. That would also go a long way to complement the wiring. Ensure you set up the parameters appropriately to suit the battery as @EarthRealm suggested. PS. Apparently the CC allows oversizing as the two panels already exceeded the power cap for 12V battery. 1 Like |
Re: Solar Energy, A Complement To FTA by mustaphagreens(m): 8:37pm On Dec 16, 2021 |
earthrealm: . There are two buttons on the CC, but I haven't quite understood their functions yet. The manual is gone but I have attached a picture that shows the spec below.

mustaphagreens: The specs show its an mppt. Budget type. 560w is max panel you shud put @ 12v. Since you have only 1 battery...most cc have allowances for exceeding the capacity..wch you are doing by loading 2 x 350w panels on it. But losses and improper orientation of the panels may keep you safe. You need to set the cc properly, i suspect.it isnt configured properly...if you have some diy skills .you can google for the manual and set the cc properly, or worst case do a video call and have a pro guide you set the cc properly. Lastly. Whats the distance btw cc and the panels. What wire size was used, 6mm , 4mm...or 10mm 2 Likes |
Re: Solar Energy, A Complement To FTA by mustaphagreens(m): 9:41pm On Dec 16, 2021 |
earthrealm: The wire is 6mm. The total length is about 26 yards. ![]() |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 10:12pm On Dec 16, 2021 |
mustaphagreens: Wow, 26yards is about 80ft, that may be why you are seeing only 31v @ cc. An original 350w panel would hv Voc of abt 45v to 48v, so under right conditions, expect about 35v to 38v at cc end. Try n confirm ur panel Voc, |
Re: Solar Energy, A Complement To FTA by ceaser: 3:11am On Dec 17, 2021 |
I noticed no one has really made comment on the cable gauge vis-a-vis the distance between the charge controller and the battery and even the battery tk the inverter sef. It appears to me that it's the same 6mm guage duo core used between the panel and the CC that is also used between the CC and the battery at such a long distance (that's like 3 ft distance between CC and battery). Also the wire between battery and inverter looks like an 8mm single. Of course suggestions mentioned earlier by other contributors still remain valid and should be considered too in trouble shooting. 2 Likes

ceaser: What should be the ideal thickness of wires from PANELS to CC and CC to the BATTERIES And also, What should be the best distance between the PANELS to CC and from the CC to the BATTERIES? Thanks |
Re: Solar Energy, A Complement To FTA by Valto(m): 1:32pm On Dec 17, 2021 |
mustaphagreens:in order not to waste resources, simply buy another 26 yards 6mm 2core and join the 2cores together and use as negative and positive then input the right settings on the CC and u are good to go.. 1 Like |

mustaphagreens: I feel you want to waste my Adding Wire, Instead Wire in Series and use money to add two more panels.. I have same the 6mm 26 yards, There is no Voltage Drop.. with 4 270w (2s2p).. at MPPT I get 60V and VOC I get 72-77V Also on your current setup Measure Voltage at the Panel, and at the end of controller without and without load to see if there is voltage drop or not 2 Likes |
Re: Solar Energy, A Complement To FTA by mustaphagreens(m): 7:29pm On Dec 17, 2021 |
Dam5reey: My roof is very steep o, not easy to access. I had called the guys that did the installation to rectify the issue today but they couldn't make it. I don't have the devices to run these measurements right away but I should get the clamp multimeter by tomorrow, with the device I should be able to measure the current and voltage at the panels and cc. I am looking to boost the current supplied by the panels, will a series connection not cause the current to drop instead? |
Re: Solar Energy, A Complement To FTA by Valto(m): 7:39pm On Dec 17, 2021 |
mustaphagreens:NO @ bolded. sorry i forget since your cc is mppt,u don't need to add wire. simply series the panels. a real 350w panel should be outputing 42V to 45V 1 Like |
Re: Solar Energy, A Complement To FTA by mustaphagreens(m): 7:42pm On Dec 17, 2021 |

Re: Solar Energy, A Complement To FTA by mustaphagreens(m): 7:58pm On Dec 17, 2021 |

Re: Solar Energy, A Complement To FTA by samnaija: 10:46pm On Dec 18, 2021 |
somebody02:Just decommissioned 4, my first of panels will do a voc test this week if you are still interested. |
Re: Solar Energy, A Complement To FTA by samnaija: 11:22pm On Dec 18, 2021 |
mustaphagreens:What is the brand of your panels and are they new. next time buying a panel carry a voltmeter and test voc before buying. Ideally your should output be 36 to 42v, without load. Since you have no access to the roof , test the wires coming from the panels into the cc with a voltmeter, this should tell you if your panels are okay. 1 Like |
