gifted65:Arent ur batteries undersized for this ur panels? The max panel watts for ur powmr is 1440w so ow did u combine urs? Do u only run a fan on it? Wondering why it wont carry ur tv unless its all those heavy power consuming type |
Re: Solar Energy, A Complement To FTA by gifted65: 5:14pm On Apr 12 |
Drgreatone: Installer said 2.5kva inverter requires lots of panel

Re: Solar Energy, A Complement To FTA by Drgreatone: 5:33pm On Apr 12 |
gifted65:Its ur loads/batteries that determines it moreso since u arent using an hybrid inverter 1 Like |

Drgreatone: During the day, it powers our freezer and other appliances which is cool. |
Re: Solar Energy, A Complement To FTA by HeavenlyBang(m): 5:54pm On Apr 12 |
Drgreatone: I'm actually very curious about this. What happens if your PV power supply exceeds the CC/Hybrid maximum pv power rating? On a hybrid inverter, for example? Let's say you have a 3KVA hybrid capped at 1440w (60A*24v). Do you also need to to limit your PV output to that? Cc: isangjohnson |
Re: Solar Energy, A Complement To FTA by Drgreatone: 5:58pm On Apr 12 |
HeavenlyBang:The danger is when the panel arrangement exceeds the VOC of the CC/inverter. Some ppl say u can still go above the max panels seeing as there are many over rated panels but never exceed the VOC of ur CC/inverter. Dunno a 3kva thats capped at 1440w. Even my 2kva12v hybrid can still take up to 2000watts of panels wit a max VOC of 400 |
Re: Solar Energy, A Complement To FTA by Drgreatone: 5:59pm On Apr 12 |
gifted65:Okay then |
Re: Solar Energy, A Complement To FTA by HeavenlyBang(m): 6:06pm On Apr 12 |
Drgreatone: VOC isn't much of an issue, as you can get past that with smart wiring. SRNE's 3KVA hybrid for example, is capped at 1440W. The popular Powmr 60A MPPT CC is capped at 1400W, even. How do people go about it?

Re: Solar Energy, A Complement To FTA by officialfestus(m): 6:32pm On Apr 12 |
Is it necessary to ground a solar panel? Or I should just install directly to my charge controller? |
Re: Solar Energy, A Complement To FTA by Drgreatone: 6:37pm On Apr 12 |
HeavenlyBang:Lolz, how's VOC not an issue? Dunno abt the srne so can't argue with you. Its fellow 3kva competitors like felicity, powmr and even sms can take way above 1440watts of panels connected |
Re: Solar Energy, A Complement To FTA by isangjohnson: 6:44pm On Apr 12 |
Last time, we deliberated on Catl cells and the results were very impressive. For three days now, I've been experimenting the bulk/absorption charging voltage pattern of Rept cells..... I'm currently carrying out the capacity test on them........ 2 Likes

odimbannamdi: It’s an inverter freezer which means it has no surge…I tried plugging it to a 2kva generator and the generator doesn’t change sound in anyway. |
Re: Solar Energy, A Complement To FTA by HeavenlyBang(m): 6:56pm On Apr 12 |
Drgreatone: Can connect in series+parallel to meet both voltage and current specifications with minimal power loss. Yeah, generally 3kva hybrids do better than 1440w, because they're equipped with 80A+ MPPTs. I'm more interested in the niche cases like the SRNE or people who use standalone inverters plus 60A MPPT CCs (Powmr's is capped at 1400W, Felicity's capped at 1650 W). |
Re: Solar Energy, A Complement To FTA by Drgreatone: 7:13pm On Apr 12 |
HeavenlyBang:We still saying the same thing. Whether u connect in series+parallel, the goal is not to exceed the device VOC or u wud be looking for trouble. Some ppl here oversize their panels with their CCs but keep a keen eye on the VOC to avoid stories that touch 2 Likes |

isangjohnson: Where do you base? Asking because I wanted to know if it’s close to Ekiti as Ineed some things there tomorrow and I don’t want to pay too much for waybill |
Re: Solar Energy, A Complement To FTA by TechGeek777: 8:00pm On Apr 12 |
Drgreatone: It can't be 12v 100Ah, as 12v 100Ah is even less than 350k if you check Valto's post. He stated 24v 100Ah. Am sure it might even be 300k/320k by then as dollar is crashing massively. Although no one is happy to see someone losing, but those who stocked dollars are regretting big time. Current rate is 1000 - 1130 per dollar depending on your source. It's expected to be around 585 - 790 by then. NB: Pls don't ask how I got to know about it! 1 Like |
Re: Solar Energy, A Complement To FTA by Drgreatone: 8:19pm On Apr 12 |
Valto:@techgeek777. That's why i had to ask if it wasnt an error by isangjohnson |
Re: Solar Energy, A Complement To FTA by HeavenlyBang(m): 8:33pm On Apr 12 |
Drgreatone: Fair enough. I've checked a bunch of forums online and the consensus is to keep your VOC within spec and the inverter/CC will just draw the current it needs to reach the maximum PV input wattage. |

Re: Solar Energy, A Complement To FTA by TechGeek777: 8:41pm On Apr 12 |
Drgreatone: Dollar was around 1608 when he posted that figure. Compared to current rate, you would know why @isangjohnson posted that price point |
Re: Solar Energy, A Complement To FTA by Drgreatone: 8:55pm On Apr 12 |
TechGeek777:Okay then, keeping my fingers crossed for his next price list. |
Re: Solar Energy, A Complement To FTA by obitobe: 9:03pm On Apr 12 |
HeavenlyBang: So you can over panel your system but ensure your connection does not exceed the specified VOC and Rated Amp for the charge controller. I have a 3600w pannel connection on a 60A, 145v Charge controller and my system is a 24v. what i simply did was to respect the charge controller specification and i have been running it for a year now without issues. The only thing is that the charge controller will limit the wattage been generated to the CC specified cap wattage and waste the others inform of heat. |
Re: Solar Energy, A Complement To FTA by HeavenlyBang(m): 9:24pm On Apr 12 |
obitobe: Thanks for clarifying. |
Re: Solar Energy, A Complement To FTA by odimbannamdi(m): 9:27pm On Apr 12 |
easyyoke: Wow! This is a pretty impressive feedback! I am completely sold. Can you share a pic of the one you have ? |
Re: Solar Energy, A Complement To FTA by odimbannamdi(m): 9:32pm On Apr 12 |
HeavenlyBang: Even though Powmr capped its 24v watt limit at 1440w, I think it does more than that. Someone here once shared a reading of 1602w. The max rating for 12v is 720w, but I used to do up 800w when I was on 12v. So, I think there is still some tolerance above that max threshold 1 Like |

Re: Solar Energy, A Complement To FTA by samnaija: 3:46am On Apr 13 |
HeavenlyBang: Thank God you have changed your mind. Voc is followed according to the cc specifications. If by chance you pass this specifications, some low end cc like power mr will give the magic blue smoke. While some other slightly highhend cc will just show error eg fangpusion, epiever till you correct it. 1 Like |
