BetaTechnicians:
Quite useful information you've shared thanks.
But I'm wondering if the bolts head won't turn freely when placed upside down inside the slot, or is the space tight enough to restrict it's circular movement?

No, the bolt head won't turn freely... As long as it's size 13 bolt, it fits well and gives you room to slide it along the rail. By the time you tighten the nut, it'll hold firm and secure

Very important to note is the fact that the foreign aluminum is softer (as I've earlier stated). Hence, after placing the panel on the rail, be very careful when tightening the nut. You have to use your sense of feel to know when it's already tight and stop so you don't end up yanking off the bolt.

In addition, you can still add a small washer to the bolt head that goes into the rail slot, but it would now be a little difficult to slide the bolt across. But if you can find a small washer that fits the bolt well, you might be able to manage

However, just be careful and sensitive when tightening the nut

Cheers

Morning house,

Please, has anybody used this newer Epever CCs AN series...? Or any sort of feedback or reviews

They come in 50A, 60A, 80A, and even 100A

Bro, I need to use the improvised mount for panels for a project, budget can't allow for the standard mounting kit.
What's the name of the aluminium form to be used and price range per length? Any other tips would be appreciated. Thanks.

Hi BetaTech,

The first picture is what I'll call the Rail. Please note that there are two types (the Nigerian and the foreign)... The Nigerian version is harder and stronger compared to the foreign.

Normally, it goes in set but, depending on the where you're buying, the guys might be willing to always sell one part without the other.
I buy the foreign own at 2,500 for the full length (18ft) while I buy the Nigerian at 6k.... Here in AKS. Might be cheaper your end

The second picture shows the other accessories... The "rail holder" cut with a 2inches aluminum angle and the panel clamp also cut with aluminum angle... Though I've seen some people use washers as the panel clamp.

NB: I personally normally use the foreign Aluminum rail for roof mounts... Whereas I use the Nigerian version (which is harder and stronger) for standalone mounts.

I hope this helps.... Cheers

but it doesn't look like it charges it... I mean my system goes off as soon as theres power outage...and the battery feels cold even when d ups is warm.... Note :d battery is outside not inside d ups... Please what can I do.... My load is approximately 200watts

Is that actually 200W? Like, Two hundred Watts.... Or you meant to write 20W?

200W on 18ah Battery is a suicide usage.

Maybe, you've actually murdered the battery and that's why it goes off immediately at power outage

Are these monochrystalline panels?

But still looking at it, you can tell it's Mono; also indicated in the model type on the sticker

Hi Oshomo,

Yes it is authentic. I posted sometime back that Canadian Solar actually remodeled their panels.

This time, their junction box is of the IP68 Split type (at the middle).

Good performance, I must also say. Installed 2.7KW (9# 300W) last year for a client and have been seeing, at peak, over 3kw.

Abeg, In conclusion we should use MC4 connectors or Just cut and join wires?

I'm thinking of MC4 connectors oo,

I remember when my panels were producing less power, I had to rejoin the wires after the wires on Yachi panel became Rusty and burnt, but the Yingli panel with aluminum coated remain intact no sign of rust at all..

MC4 is a good option, provided it's a good quality one.

Personally, I do use a kind of terminal connector shown in the picture, as long as it's protected from any weather condition (rain or sunlight). I can easily screw and unscrew cables in it...

And I normally, after testing and commissioning, still properly cover/seal up the open ends of the connectors

Cheers

I bought those useless luminous batteries myself from Simba in Lagos and had them shipped to Anambra.

I was so disappointed with the batteries when I saw each of them drop to 9v during load testing.

I didn't bother calling the Simba even duh they muted warranty when I was paying for them but I know how warranties work in Nigeria so I have made up my mind to discard the batteries. I don't even have flight money to spare to go to Lagos.

My problem now is which batteries do I go for?

I have been researching about the claim that having batteries on float almost all the tym is not good for batteries
Even duh it discharges every nite to about 15% DOD

Lithium batteries are out of my option coz it's in a remote location and indoors wouldn't want to burn down my inheritance

Sorry for the loss... It's a very big one.

Though since this Luminous Blue came out, I've only been hearing bad reviews for it. Their yellow mode was a little better.
As a matter of fact, a Solar Company here in Eket carried out a capacity test on the Luminous blue and got about 87%.... Very poor I must say.

I also know a boutique that is using 1.5KVA/24V Sukam falcon plus with the Luminous blue. Loads are just the lights. No fan sef, just lights and they have never drained it to alarm level. After 9 months, another story... And two or three other negative feedbacks from users.
I've been discouraging people from going for this Blue model

I believe it's a factory issue. Same thing that happened to PRAG battery sometime. After they modified their battery and it started have early failures.

I might not be able to suggest the best battery, because I've not actually used or installed all. But Over 5 years now, the two batteries I can vouch for are Quanta and Safepower.... Both are Indian

From Chinese angle, I've also come to trust Mpower (distributed by AirWave Ltd)... I do use them for clients on low budget.

All the aforementioned are from my personal perspective.

As for batteries always being on float charge posing a problem, to me it's a fallacy. As long as the float voltage of the charging source (Inverter or PV) is within the recommended voltage of the battery manufacturer. For example, almost all inverters have a default float voltage of 13.7/13.8V. But Quanta strictly recommends 13.5V as the float voltage. So question is what happens when you have Quanta batteries that are being subjected to constant float voltage of 13.8V?
These days, people just randomly choose Inverter and batteries without any form of regards to conformity and compatibility.

Finally, looking at your setup, it can be seen that your battery arrangement calls for long battery interconnecting links at some point. I hope ALL the links are same length and same size. Not that some would be short and others long...

As for the Battery balancer, if it's HA02, then I believe it shouldn't be a problem. Unless it's all those Sukam and few other "unbalacing" balancers.

Once again, sorry for that heavy loss. 12 batteries no be beans, even if you're Chevron manager ( lolzzz)

Cheers

Nix insulation but depending on your location that solar array may not be able to effectively charge that Battery bank especially if the batteries are discharged below 50% DOD.

In PH the average solar sun hour is 2hrs but on some days gets to 3hrs.

A 3.6kw solar array will produce max 7.2 - 11.0 kwh daily.

Your 28.8kwh (which I'm assuming is 48v 600ah setup) can give u max 50% DOD which is 14.4kwh.

That leaves u with a shortfall of about 3-4kwh (basically ur absorption tym)

It's 19.2KWh (400Ah at 48V).... Mistake. Already edited. Thanks .

And going through the record last week, the lowest the client has woken up with is 49.2V

Thanks for the compliment sir... Location is AKS.

Installation was executed October last year... And battery bank floats every day since then. And I mean, EVERYDAY.

However, that challenge is definitely expected come rainy Season. And there's actually a plan to add 3 Panels to each stream later this year

Moreover, I actually noticed that Canadian Solar modified their PV modules (design-wise) which seems to be "over efficient", from practical monitoring and observations.

Thanks for the observation... Cheers

My brother, this might just be like most stupid Chinese and other (even Indian) substandard batteries that so flooded the market now... You'll see a conventional SMF LA battery rated 12V 200Ah being sold at 85k, but in essence, it's 150/160Ah.

Yes, but.... Any conductor can be used, but it will not be as effective as copper. The idea of a lightning arrestor is to provide the path of least resistance to the earth, that is why pure copper is used since it is the best available and affordable conductor.

thanks Adrusa...

but the cable in question is still pure copper, but the flex copper (the type used in DC wiring).

the typical stranded copper (for AC wiring) is usually used for grounding... wondering if the flex copper cable can also be used.

So decided to try out quanta battery.
Looks really well made and high tech.
Though observed slight swellings on the 3 compartments of the battery.....is this normal.

Abeg quanta users should chook mouth

2ndly the boost charge voltage spec on it is 13.8v, while float is 13.5v, this is about the lowest i have seen. And would spell disaster for folks fond of mixing diff batt makes.
My usual long batts hv boost of 14.6v and float of 13.7v

Hi Earthrealm,

its not really a big deal... just that the angle you snapped it from exaggerates it.

Quanta comes like that, with those "soft bulges". same with Safepower batteries... they're never smooth.

Topmost11:
I'm getting additional two 150watts panels before December.
Will someone pls tell me how many watts will charge 400ah battery conveniently in a day with 12v inverter and as an alternative, with 24v inverter. I am yet to grasp how to do the calculations.

400ah battery.
Whatever panel wattage that will charge it in a day
12v or 24v inverter?
That's my dilemma now

Hello Topmost11,

First of all, there's a general calculation used to determine the size of PV array for a particular system, and it has to do with using the average hours of sun in the day and other many scenario.

however, I'll show you how I personally do mine looo�.

secondly, I'll go the 24V way.....
so, for a 400Ah battery bank, you need a minimum charging current of 40A (10% of the battery bank capacity). However, some battery have exception to this: Quanta Amaron can take up to 25% of its capacity!

so at 40A charging current, you need 960W PV Array (i.e. 24V x 40A)

Nonetheless, there are other considerations like day loads, panel inefficiency, and cloudy moments....

if you decide to add 10A to take care of the day loads, you'll have 50A.

That'll be 1.2KW PV Array (i.e. 50A x 24V).

However, you should round it up to 1.5KW PV Array, to take care of inefficiency.

Note that the above is strictly my personal approach....

Cheers
