Dam5reey:Does the highlighted mean battery connection should be in series rather than in panel as currently is? |
Re: Solar Energy, A Complement To FTA by Dam5reey(m): 5:21am On Jun 11, 2017 |
davodyguy: Yes, this will make your battery system 24 Voltage.. and capacity 200Ah.. Rather than your 12V 400Ah. however, you will need to change the Inverter to 24V.. Since your Panel is 800Watts.. you can use a 24V 40A MPPT controller, which will take 1040Watts panel at 24V |

Dam5reey: Good morning For now, I do not intend to change inverter How best should I go about my 1000 watts 12 v 400amps battery 800 watts solar panel Mppt 40amps charger |
Re: Solar Energy, A Complement To FTA by zeestone99(m): 9:03am On Jun 11, 2017 |
davodyguy: Jst check if ur mppt has a nominal voltage of 12v, if ur panel is 24v,u can connect ur panel in parallel or even series two 24v as long as it doesn't exceed the max input voltage of the cc(usually btw 100v to 150v).the Mppt ll tk care of the rest. Also check ur nameplate to mk sure u r nt exceeding the current ur controller can dish out |

DMerciful: I'm afraid DMerciful is quite right. Oshomo12: You would have noticed a similar difference even with professional roof mounts. Mine have absolutely nothing underneath them and I had the same experience as you had. What you did was bring the temperature down closer to the lab temperature of 25oC. I had posted a year or two ago the impact a brief rain has on them, in addition to the bright "flare" immediately after a midday shower. The margin will also reduce as your panels age and their efficiency drops. Believe me however when I tell you, you can have 80% losses from poor angling. In an experiment I conducted under non-standard conditions (but otherwise reproducible), the difference between placing them flat and angling them 30o due South is about 30%. Give it a try on a clear and sunny day, around midday. Mine are angled at 8o due South (they accumulate dust faster and pool water when placed flat). |
Re: Solar Energy, A Complement To FTA by Saipro(m): 9:27am On Jun 11, 2017 |
Dam5reey: PWM doesn't really do energy conversion. That's why losses might be great if there's a panel voltage:battery bank mismatch. And if they match too closely (to ensure max efficiency), you'd get pitiful charge on cloudy days - unless your bank is quite depleted (not good). Also, as others have mentioned, unless you have your panels and PWM controller sitting directly above your battery bank, your losses might be significant. And it's a waste of good copper buying cables as thick as your wrist, even if you could afford them. 2 Likes |

There must have been a huge power surge in my area overnight. I woke up this morning to discover my Midnite Solar Surge Protection Device MNSPD300 completely damaged. Thanks to the MNSPD300, none of my gears was damaged. The device was installed on the PHCN grid supply to the house 18months ago. You are all invited to the survival party. 5 Likes

Re: Solar Energy, A Complement To FTA by DMerciful(m): 7:26pm On Jun 11, 2017 |
I use stabilizer for incoming Phcn. Any over voltage is taken care of by the stab while displaying unusual with no output until d voltage is normalised that way I don't loose anything. I think that's a more cost effective option dapsyra: 3 Likes |
Re: Solar Energy, A Complement To FTA by mank1234(m): 8:45pm On Jun 11, 2017 |
You need both surge arrester and voltage regulator. They are for different purposes. Transfer time of relays in stabilizer is in milliseconds whereas lightening induced overvoltage occurs in microseconds. You're protected against overvoltage but not transient current when you use stabilizer. His surge arrester got fried from prolong exposure to overvoltage which a stabilizer could have prevented. On the other hand, a stabilizer may be fried from a single lightening transient unlike a surge arrested which will only deteriorate. DMerciful: 3 Likes |

zeestone99: 200 watts panels x 4 made by frames How many amps charge controller would work for a parallel connection for the 4 panels to charge 2 now 12 v 200amps batteries? |
Re: Solar Energy, A Complement To FTA by zeestone99(m): 11:30pm On Jun 11, 2017 |
davodyguy: My advice - buy a 1.5/2kva 24v inverter, one 40amps Mppt charge controller, sell ur 1kva/12v inverter. Connect ur panels 2×2 config. #cheers N:B you can get gud used inverter at affordable prices from pple that upgraded their system 1 Like |

Re: Solar Energy, A Complement To FTA by chris81964(m): 3:12am On Jun 12, 2017 |
davodyguy: If you have a good quality inverter keep it. You have 800 Watts in panels. Divide by your inverter voltage. That will give you the size of controller you need. 2 Likes |
Re: Solar Energy, A Complement To FTA by chris81964(m): 3:16am On Jun 12, 2017 |
davodyguy:If you can afford it a good quality MPPT. If your application does not require deep discharge of your batteries then a pwm will do the job. More tricky to work with but they do the job. |

Re: Solar Energy, A Complement To FTA by Saipro(m): 7:09am On Jun 12, 2017 |
dapsyra: The thing is all burnt up! Looks like a sustained surge (if such a thing exists/grid overvoltage). Or a direct hit by lightning on a line very close to you. You're one lucky man indeed! Party time!!! mank1234: You're right. AVRs won't protect against surges and brownouts. A fuse has a better chance (if the surge current is high enough; rarely ever so). In addition, there are instances the surge is so powerful, it freezes the AVR in "on" mode thus transmitting the entire surge/over-voltage through. I have an 2kVA AVR which is no more than than a mere 10V booster as a result of that. |

chris81964: I did the analysis already... On previous posts. He need 60A charge controller which would cost more that 40A MPPT.. it's better to have 24V 200Ah Bank than 12V 400AH.. |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 8:43am On Jun 12, 2017 |
Saipro: just a heads up, there are basically 2 types of refrirant the older r600a - toxic, outdated, gradually being phased out for domestic applications in most western countries, chills faster/more efficient and r134a - newer, genrally accepted, doesnt chill as much as the toxic r600a thats why older cars chilled better and faster than the new cars, even fridges and freezers, cos they used r600a back then, which is toxic/harmful and require careful handling, causes ozone layer depletion etc. govts had to step in to effect the change to the less efficient but safe r134a, thus r660a gas and components are a bit scarce and thus also more expensive |
Re: Solar Energy, A Complement To FTA by Dam5reey(m): 8:55am On Jun 12, 2017 |
davodyguy: It's possible.. with Epsolar MPPT controller... 40A.. however you will still loose power during peak periods.. Connect in 2 x 2 strings... Option 2 buy 60A, 70A MPPT controller as I stated earlier.. 800Watts will generate Approx 60A at 13.8 float charge... 1 Like |

Dam5reey: So the difference in cost between a 40 A and 60 A is more than the cost of replacing his inverter. Let me make sure I understand you. He already has an inverter. You want him to forget his inverter and buy a 24 V inverter to justify buying a 60 Amp controller. Is this what you are asking him or her to do? |
