Konnektions146:You can use as many controllers as you want. Make sure you make adjustments to the settings for your equalize cycle. Also most brands will allow you to parallel multiple controllers.

Konnektions146:bros please read the post again. I didn't in anywhere say any cc on 24v can produce 3200w. Anyways the one I have can accept 3.2kw solar panels but can only max out 1040w. I could remember Richmond has extensively explained clip off in this forum |

Re: Solar Energy, A Complement To FTA by monknaija: 7:22pm On Jan 04, 2016 |
you guys are great . have been silently learning from the gurus in house. now I have finally plunged in. house I have 12 poly panels 24v 280watts each, a episolar charge controller mmppt 60amps, my system is 48v 200ah. my question what is the best solar panel arrangement to maximise or give the best out of my panels. pls appreciate assistance want to get this aspect correct b4 moving forward.... |

Re: Solar Energy, A Complement To FTA by c0ogumo(m): 2:24am On Jan 05, 2016 |
monknaija: Since you have an MPPT CC, you should arrange your panels in a 3 x 4 configuration i.e 3 panels in series and 4 panels in parallel. If the distance from you panels to your charge controller is far, then you may consider a 4 x 3 configuration. Let us know the outcome this setup. |

AkoEja: Frankly, any reputable deep cycle battery which matches your budget. I use flooded lead acid batteries and favour Trojan (extensive research and availability). And the cost per kWh is perhaps the cheapest on the market (you have to consider cycle life). Hoppecke would do but seem a bit more expensive per kWh. Rolls Surrette would do fine but I've seen just one set in the country. I think it's more popular in the USA. For the "cheaper" AGM and VRLA batteries (they're not cheaper by the time you factor in cycle life), I think Exide and Zenith rule. Luminous seems quite popular and I've seen them work fine when used right. Sadly, occassionally a battery randomly fails and Luminous seems more prone to this. I've seen two Chinese brands work wonders over the past 2 years (most I've seen fail within 18 months) and I'm still watching them. Will give feedback when they clock 3 years. Ask GeorgeD1 about Zenith batteries. His testimony is inspiring. For Trojans, ask any major dealer here. Be sure to go for the 6V RE series. Those ones are engineered specifically for renewable energy cycling and use. Difference in cost is marginal. Trojan makes other long-lasting deep cycle batteries and their testimony is similar to what you might get with the RE series (but slightly shorter cycle life). If you've got deep pockets, give the Idustrial series a tryout. That's one set of batteries engineered to withstand abuse (so long as you neither overcharge nor undercharge them). They also seem to live forever. I use Trojan batteries. For the Exide (an Indian brand), and other good Chinese brands, find a reputable dealer on this forum too. I've seen too many imitations and repackaged ones to emphasize the point. Avoid untested brands unless your gut goes with it. Blame no one for the results, when you do. I hope I haven't confused you with the options. Making an informed choice is the way to go as individual needs vary. abunafiu: Bros, you're not alone o! Who no like good thing? ![]() 1 Like |

JUO: Boss, I think you misunderstood me, The guy said he needed 1pc CC of 160A rating because he has 32000w PV for a 24v System setup. You suggested 3 by 40A CC ( reason being his system voltage rating as limitation) He said he does not want to use more than 1pc CC on his setup for his own reason. my statement was actually to him which implies he should go with your option. cheers |
Re: Solar Energy, A Complement To FTA by Konnektions146(m): 7:45am On Jan 05, 2016 |
chris81964: Thanks Boss What i actually meant was that NO single CC to the best of my knowledge can do 3200W PV for a 24V system. See bolded below Liveair: |

[quote author=Saipro post=41436938] Well, it would be unfair to state that the functioning of the firmware of the EP Solar iTracer is not an exact science but thus it appears at times. It simply emphasises the fact that the SOC is a poor measure of true state of charge. I had to buy a reliable hydrometer to put my mind at ease. Having said that, the observations you've stated are weird. Unless you're consuming more than you produce in the early hours of the day (my electric kettle is fired up at the crack of dawn and sometime between 8am and 10amm the fridge then freezer start up in that order), your SOC should be rising not falling, regardless of the what's going on. It might be a fault in the CC but before we jump to that conclusion, try the folowing in this order (assuming you use FLA batteries): 1. You won't believe the sun changes its path significantly during the course of the year, even the tropics. Be sure your panels aren't deep in shadows in the morning. I noticed the iTracer somehow "feeds back" the solar panels during the dark hours up till early dawn. Results of extensive isolation tests and data collection. 2. Early in the morning, not the SOC then disconnect all loads from the CC (inverter inclusive). Monitor SOC every 30 minutes till noon. It should keep rising, gradually at first but more rapidly as the morning wears on. If it doesn't and it's not from [1] above, your device might have an issue. 3. Whip out your trusty hydrometer. Test a battery you're sure is okay and representative of the bank take SG readings every hour from 8am till 2pm. No load. IT MUST CONTINUALLY RISE TILL ABSORB VOLTAGE IS REACHED AFTER WHICH RISE THEREAFTER MIGHT OR MIGHT NOT BE NOTICEABLE, DEPENDING ON THE HEALTH OF YOUR BATTERIES. 4. If [3] above doesn't help, proceed to check SG in all your batteries. While an unlikely source, a single dead cell has been known to cause haywire readings. Multiple cells may decide to abruptly go bad. 5. Measure VoC incoming then after closing the circuit. See if it correlates (+/- 5%) with the display of the iTracer. Notice the Vmp on display and confirm likewise with your meter. 6. Seek a "professional" who would look over your system to give analysis and possibly diagnosis. Kindly give feedback. I at this point implore otherwise who've had more experience with iTracers to come out and render some counsel. Afterthought: I remember an issue I had with a friend's setup once. It's possible you're somehow reaching float by 10am and voltage falls thereafter. In addition, if you're simultaneously charging from another source (say the inverter or a second CC), you might have that problem too. The display merely shows what the iTracer thinks. 12.6V is okay as float and will show 100% but the same voltage might register 70% or less SOC during bulk (for a 12V system). Another instance I've seen that issue is with and absorb duration set pretty low (say 90 minutes? 60 minutes? Lesser?). What's your set absorb duration? What's your voltage for rebulk? thanks for the extensive explanation, 1. i jst hv a single cc, no multiple charging source[s] 2. the batts are ]sealed] thus cant check cc 3. the panels are never in shadow...full sunlight alll the time the major culprit could be a failing battery, 1 batt reads 12.5v, the other usually reads 10.5v when its running down/under load....luminous batt...i complained earlier b4....it sxeems luminous inverters usually kill the negative batt..as this is my 2nd experience with a failing -ve batt on luminous set up...will wait until i have good batts b4 carrying out the other suggestions you stated. note: i have a batt desulphator hooked up to the bank..for about 1 wk now......didnt take note if the issue was b4 or after the desulphator was hooked up........intend to remove the deslulphator and observe for changes..... |

monknaija: @monknaija 3 x 4 Configuration 1st step, you need to connect 3 panels in in series i.e connect the +ve of the first panel to the -ve of the second panel and then connect the +ive of the second panel to the -ve of the third panel. 2nd step, repeat the first step for panel 4, 5 and 6. 3rd step, repeat the first step for panel 7,8 and 9. 4th step, repeat the first step for panel 10, 11 and 14. Now you have 4 strings connected in series. 5th step, connect all the -ve in each sting together and then connect all the +ve in each string together. You now have just 2 cables one +ve cable and one -ve cable going into the PV terminals of your MPPT charge controller. Please see the attached diagram and let me know if you have questions. 1 Like

Hello Gurus, Good day all. Please I need an advice for a good friend ( an alternative energy freak) He has 4 solar panels with the following specs. Rated Power= 130W Rated Voltage= 17.5V Rated current= 7.42A Open Circuit Voltage= 21.7V Short Circuit Current = 8A Maximum System Voltage = 600V Cell Technology= Polycrystalline He connected these panels in series to the MPPT Charge Controller He has a 150V 50A MPPT that he is using. He recently acquired two more solar panels with the following specification: Peak power ( PMP) = 250W Open Circuit Voltage(VOC) = 36V Max Power Current (IMP) = 8.33A Max Power Voltage(VMP) = 30V Max System Voltage= 1000VDC CELL TECHNOLOGY: MONOCRYSTALLINE Now the big question is this, which configuration is best suited for this scenario? Series or parallel connection? Please explain as he is currently confused. Thanks y'all. |

Im2Busy2Bother: I would buy a second controller and call it a day. Less headache and not much in the thought process department. Should he decide he needs the headache, the voltage of his existing panels needs to be brought close to the voltage of the newer bigger one. He will lose some of the benefits he got from buying the larger panels after going through all that headache. My two cents. |
