dapsyra: hello dapsyra, thanks. i'm still experimenting with the midnite solar. i will try changing to the "legacy P&O" mode and see if it finally overtakes the tristar in terms of daily harvest. |

now, for my vote of thanks: juo is the man of the moment! it has really been a very tortuous journey for me. i set out looking for the best and most economical way to replace my tristar mppt-60 which obviously was undersized for my solar array and i searched in a number of places, contacted quite a few sources both here and outside the forum and ended up disappointed. i noticed that most sellers still carry prices of items calculated at an exchange rate of 450 to 550 naira to the dollar. over seven months after dollar has reduced to 365 naira and below, these peeps choose to bury their heads in the sand and pretend not to be aware of the current realities. in comes juo the life saver! here was i chatting with this unassuming seller on this thread via watsapp and narrating my ordeal to him and the next thing i knew he was already making arrangements to get me a midnite solar classic 150 at an incredibly mouth-watering price. initially i thought it was all a joke until i got that much anticipated call from him telling me that my cc was ready for collection. at the end of the day when i compared what i paid to the amount that a popular online store is selling their midnite, i just shake my head in disbelief. not only has juo proven to be a reliable guy to deal with, he has always been consistently delivering quality products at unbelievably low prices and this successful deal adds another feather to his cap. 15 Likes 1 Share |

all, so finally here comes the head-to-head comparison between midnite solar classic 150 cc and the tristar mppt-60. 1) build the tristar comes solid as a rock made of an upper cast aluminum and a lower steel body. so also the midnite. it looks rugged enough and its appearance exudes quality. a mere glance gives one the impression of high quality. -both charge controllers take this round equally. 2) installation both charge controllers are easy to install with both shipping with a battery temperature probe as standard. clearly marked positive and negative battery and solar pv terminals reduces possibility of error. - this round is also a draw. 3) setup setting up the tristar is a little tricky as you'd have to fiddle with the notorious 'dip switches'. from system voltage settings to battery type selection and equalization, you will do well to read your manual over and over to make sure you don't flick the wrong switch else you might just kiss your precious controller goodbye. the midnite classic on the other hand is a beauty to set up. the built-in wizard helps guide you through the set up process and you could be done in minutes without even opening one page of manual to read. it is that easy. -the midnite solar wins this round without contest 4) programming, fine-tuning, etc coming closely on the heels of setup is programming and fine tuning the charge controller. the midnite solar has quite an impressive list of user adjustable settings that you could carry out directly from the mngp (display unit). you could also use the wizbang jr add-on to achieve this. and this helps to make the unit very flexible and user friendly. the tristar on the other hand is not that easy to program. i've mentioned the dip switches already. to adjust the few settings available you will need to install the optional 'msview' software. -again the midnite classic wins this round. 5) connectivity, internet, etc both charge controllers connect to the internet when properly configured but it seems the midnite classic has a more seamless architecture. configuring the modbus for the tristar has always been a pain in the ass for me. - midnite classic wins this round 6) performance, solar harvest, ability to optimize yield even in cloudy weather i rotated both charge controllers from north facing panels to south facing panels over the course of two weeks and monitored their performance with the different arrays. i discovered the tristar always being first to wake up from night mode or 'rest' early in the morning and being the last to go to sleep in the evenings. also conversion wise (dc to dc) the tristar seems to shine. however what the midnite classic lacks in terms of its inability to wake up on time, it tries to make up for it by its superb solar algorithm - although it finds itself always trying to play catch-up for the rest of the day. for most days, production from both charge controllers were almost equally matched with only a little variation. - this round is a draw with the advantage tilting more towards the tristar. 7) durability, reliability, etc like i said in my earlier post, it's still early days yet with the midnite classic cc so i may not be in a good position to tell how durable or reliable it may turn out to be. however, i can vouch for the tristar as a solid and reliable unit able to withstand almost anything thrown at it. unless you deliberately set out to damage it, this cc is guaranteed to serve you for many years to come. - this round is inconclusive 8 ) scalability, ease of expansion, etc perhaps the biggest selling point and over-aching advantage the midnite has over the tristar is its ability to produce between 80 to 96 amps of charging current with a maximum solar array size of up to 4,300w at 48v. that means as a user there is more room for expansion. you can start with a few panels and continue building up your system on an incremental basis by adding panels after panels without worrying about changing/upgrading the charge controller. the tristar on the other hand maxes out at 60 amps which translates to 2,300w at 48v. anything above this and the current limit alarm set in. - midnite classic is the winner for this round 9) conclusion as can be seen, each charge controller has its own strong points and not so strong points. also, they seem to match evenly in quite a few areas. at the end of the day, its much like comparing ronaldo and messi - both are kings in their own rights - or comparing apple and android. while one is a closed system and difficult to manipulate, the other is flexible and easily configurable - but they both excel in what they do. 10 Likes |

now for the review (and i'll try to make it as short as possible): out of the box, the midnite solar classic 150 feels solid and well built. it's very much unlike the numerous cheapo charge controllers flooding the market these days. installation was a breeze partly falling back on past experience and partly referring to the manual that came with the cc. programming the controller was a piece of cake using the built-in wizard that comes with the mngp (classic display panel). performance wise the midnite classic didn't disappoint. from day one it didn't waste time before displaying the stuff it was made of. through the clouds and sunshine, it kept pulling in every bit of juice it could get. as for durability and reliability, it remains to be seen how long the controller will keep on putting up this type of stellar performance without issues. time will tell. next i will be comparing the midnite solar classic and the tristar. this is where things begin to get more interesting. |

Oshomo12: oshomo, wind turbines would be an attractive proposition down here in the south-south especially for the period between july-august. if i can lay hands on an efficient and reliable one with a cut-in speed suitable for the prevailing wind characteristics, what a boon that would be. |

bigrovar: hello bigrovar, you're very much on point. the july-august rain belt is proving to be an especially hard one to swallow most especially with the weather pattern this year. some days even with my over 7kw solar array i'm barely able to generate 5kwhr total production. i'm only now beginning to realize that i actually need more panels to tide me through the dark days. but again, like you said, oversizing has its limits. i was talking to someone early this afternoon and i said putting out more panels on a dark cloudy day with zero sun is akin to lining up empty plastic buckets to fetch rain water. even if you have 1000 buckets lined up, if there is no drop of rain you realize nothing at the end of the day. same thing goes with solar. a million panels stretched out on your roof with zero sunshine will yield zero kilowatt-hours! 5 Likes |

Nkdave: nkdave, welcome on board. even though its not really advisable using trailer batteries for inverters, since you say its a temporary solution, no problem. to incorporate solar power for your setup, here is what you need: 170ah multiplied by 1.2 (to account for system losses) will give you: 204ah this gives a total power output of 2448w (assuming you are draining down to a dod of 80 to 100 percent - which may not be practical. for a 5 hour average daily insolation, you can get by with a solar panel array of between 400w to 600w depending on cloud cover. as for your brother, you need to get back to us with actual nameplate power ratings for all the equipment mentioned in your list if you want proper system sizing advice and cost. 1 Like |
Satellite TV Technology / Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 10:39pm On Aug 13, 2017 |
prof, sorry for the loss. like dunka, i will advice you go for a steel tower this time. if you insist on erecting another concrete tower and you really want to do a good job, you will discover that the cost would be almost the same as setting up a steel structure when you quantify the iron rods and cement involved. 1 Like |

khanka, your budget should be able to get you a high end 24v inverter which incorporates all the mention features and much more. also, most inverter manufacturers now have local support within the country in one form or the other. for instance when i had issue with my magnum inverter, even though its an american product, i was still able to fix it through support from their local rep in port harcourt. |

dicksonadams: i had a similar experience like johnkester with my newly installed solar panels. after installation, i noticed one array was producing roughly half the power output of the second array and so i set out to troubleshoot. in the process i climbed to the roof only to discover that the mc4 connectors of two array strings were not properly closed. what that meant was that out of twelve panels, only six were producing thereby explaining why the output was half. i quickly reconnected them properly, climbed down from the roof, switched on the array breakers and voila! more amps than i could imagine started pumping into my cc. it was really a remarkable experience for me. 2 Likes |

DUNKA: dunka, my candid opinion is to get an independent tower to install your water heater. however, if you insist on installing it on your aluminium roof, make sure you consult your carpenter for proper reinforcement of your roof polines and beams. i had similar thoughts like yours when i was going to acquire my own 300l but after it arrived and i had it assembled, i was like "wow!" "there is no way i'm going to place that massive frame filled with water on my roof!" so, i instantly began discussions with my welder for a separate water tower. |

earthrealm: earthrealm, like i said earlier in the year, anybody can install a solar hot water system, be it a landlord or tenant.for the tenant, the major challenge is where to put your water tower in case you want a gravity feed system. however, that can be overcome by installing a pressurized system. with such a system, the unit can be installed anywhere on the ground facing the sun. all you need is a pump to supply the hot water on as needed basis. its really amazing what the human mind can achieve when you set it to work. |

pranil, i don't know what's happening but any time i quote your post i get banned for twenty four hours. anyway, i'm sure you already seen testimonials from johnkester who happens to be using a similar brand as mine from the same supplier. as for temperatures, recall that earlier in the year i did a comparison between the conventional (ariston) electric water heater and its solar counterpart. these days, depending on the degree of cloud cover, my water temperature still gets above 40c which definitely is more than what i need to take a hot bath on a cold day. believe me when i say that solar water heating is the next best thing to sliced bread - and if this coming from a guy who is not trying to sell you anything, it should speak volumes. 5 Likes |
