yuzedo: Wait, really?? grin

This is unadulterated FUCKERY! undecided

We are so used to misgovernance that a common borehole is commissioned/approved by THE PRESIDENT and people are commending him. WTF guys?! Water that is every student's right, even those that haven't paid school fees. IT IS NOT A PRIVILEGE!

Imagine Obama commissioning borehole in Howard or CUNY and it makes news, i mean, even a Mayor middling civil servant wouldn't flippin' do that! Chai... Nigeria, ndo!
Nigeria!, the land of the absurd. embarassed

@pdozie, smiley smiley congrats, I'm especially glad you're using all of your batteries. With some more panels and and increased battery bank, NEPA can get lost for even more than three days.
Well done.

Akanniade: Careful there so you dont blowup your meter. The current limit (usually 10A) your meter can measure is usually printed near the socket where you plug in your positive lead for current measurement. Ensure the current you want to measure does not exceed your meter range. Otherwise go for a clamp on ammeter.
@pdozie, Akanniade is absolutely right. I made the assumption you had an ammeter of the appropriate spec.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ilenaira:
bodejohn: But in the case of ile naira, they are different brands.
Que pasa? huh Me no understand

@pdozie, it is probably safer to use one set. For how long have you had both sets of batteries connected?. Did you notice anything about the batteries? You seem to have verified the voltage across the resulting bank, did you do the same for current? I feel your concern about seemingly wasting a set of batteries but whichever way you decide to go, your purchase is not a waste. If you're confident everything checks out, use them all as plannned otherwise, sell one set and buy more of whichever set you've retained.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ilenaira:
Thanks akanniade, I'll give Arthur a call.

@pdozie, it sounds like you're on the right track with the info. you've given. I'd be very wary of mixing old and new batteries though, the lowest common denominator usually wins, i.e. your new batteries will be 'dragged down' by the weakest . You may be better off with just the new batteries.
I also hope they are all of the same current and voltage rating.

edit:
If I read your post correctly, I think you just have one 'bank' rather than two. You have a set of new batteries(4 in series for 48v) and another set of 'old' batteries also of 48v. Left at that, you'd have two separate banks (at however many amps), but since you've then conected both sets in parallel to increase your amperage, they become one bank of 48v and the combined amperage of each set.

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ilenaira: 9:02pm On Feb 13, 2013
@bodejohn, the turbines in Europe are in vast open fields and not not built up areas, that's a big difference. Also, domestic installations in Europe may have a better chance of working due to enforced town planning laws.The same cannot be said of what typically obtains in Lagos for example.

By 'coastal' in my last post, I was referring to the sea rather than river. So countries with wide coastlines rightly exploit it. Scotland and Sweden for example, have huge wind farms because of their coastal terrain.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ilenaira:
@bing, compared to the relative certainty of the sun rising each day, wind turbines will always come second unless you're in a coastal area (even that offers no guarantees). As far as I've seen, domestic use of turbines has always been in conjunction with solar or hydro, rarely is it applied on its own. Large scale grid applications of turbines tends to be in high altitude or off-shore locations.

I don't know the average wind speed in Lagos, but I do know that a 3 storey building can spring up in a street designated for bungalows and nothing will happen. You might stand a better chance if wind flow is not blocked in such a way.

S-l-o-w-l-y getting there, more arrived today. grin

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ilenaira:
George, very good points and well-made, but the willingness to try other manufacturers is not down to price alone, at least not for me. Innovative small companies, new-comers and established but unpopular old-timers all deserve a chance and a second look.

You're right about some dodgy Chinese products but you might also be doing the honest Chinese Manufacturers a disservice by lumping them all together. I think it is always the case of buyer beware and if in any doubt, go for the devil you know rather than the angel you don't. Me, I never just look and buy, I always get evidence of on-field use and opinions of such users before parting with my hard-earned money.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ilenaira:
shocked @bodejohn, you may have spotted something I missed : the waveform. lipsrsealed Thank you.
In my excitement, I assumed it was pure sine wave. That's partly why I requested a spec sheet. I wasn't worried about batt charging, but an inverter is useless to me if not pure wave.
Damn, I have to forget that inverter and start looking again. sad

As for being scared of China/ the Chinese, the answer is yes and no. I have no problems with trade, friendship, partnership etc, but with a tilted balance of economic power and thieves in our government, I fear. Our continent and people have been through too much to sleep-walk or be sold into colonisation again. Anyway, this is not the politics section so I'll stop there. wink
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ilenaira:
George, if you need isolators or dc breakers let me know. I can pick them up as I get mine. The same for busbars and terminal blocks.

The inverters that I've seen are from China

(here's a not so great advert for it on you tube, the guy had wired them incorrectly)
https://www.youtube.com/watch?v=N8M9A8hd62E.

They are quite easy to set up and apparently have double their stated peak power as the surge rating. They can also be used individually if you want to dismantle your set-up or sell on in going to single inverter. I am just waiting for the specs first before I commit. The only downside I can see is that there is no display panel on them from which I can get feedback on power output /dignostics/ etc. I just cannot ignore them as the price for the 2-3 pieces I need will not even buy me one Xantrex or Outback equivalent, let alone 2.

If the specs don't convince, I'll stick to one inverter.

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ilenaira: 5:20pm On Feb 05, 2013
George_D: ................ i became relaxed when i saw that the roof structure was solid enough to withstand the extra loading...............

you may have to start thinking of incorporating periodic roof washing if you want your panels to continue performing at their best. just a thought.
It's good your roof is solid. I'll check mine If I can use the roof then I can have more panels and let the rain and gravity do the washing.

I found inverters that were designed to be stacked and the best thing is they are not the expensive Outback/Xantrex examples. I've asked for the specifications from the manufacturers. Still waiting. Oh, the first of my PV project material turned up today. cheesy A DC Isolator. I just need everything else to connect it to to arrive. angry

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ilenaira:
George, apologies for the late reply, I've been busy looking into my fears about the Lagos port and it's not good. I have had to let go of the 2v cells I was going to import. Everyone to a man said DON'T DO IT! Not with batteries anyway sad

On the plus side, I completely agree with you, I looked at my array design again and I've increased the voltage but reduced the current by tweaking the series/parallel layout.
I will not be needing an expensive 90 amp inverter anymore. I'd decided on 2 x 60A charge controllers anyway (to minimise damage risk and future expansion purposes just as you've implied). The charge controllers are fan-less like your Tristar which makes them smaller and less complex. I'll go and look at stacking two 3 Kw inverters too. Thanks.

Out of interest George, did you carry out any roof-loading calculations before mounting your panels on the roof?. The destination for mine is the flat roof of the car port (the optimum tilt for me is 5 degrees anyway). I could expand by using the main roof but I'd have to get up and have a good look to even begin to think about it.





George_D: ile-naira,
still on the subject of stacking, i want to chip in a quick note:


even with a well-planned forward looking system, stacking of charge controllers and inverters is never
out of place. this is so primarily due to the huge advantages it affords.

...........................
still following the example above, 2 sets of 3kw inverters stacked together will enable me continue to enjoy
power even when one of them is taken out for service. and then imagine if you had a single large 6kw inverter
that suddenly went bad! you'd be out of power for as long as it takes to get it fixed or maybe you'd switch
over to noisy generators for that period. but with 2 stacked 3kw inverters, the two cannot get bad all at
once.

same goes for charge controllers. if i had a single large 90a charge controller and it was affected by
lightening that will mean no more solar charging until it was repaired or replaced. but if i were to stack
2pcs 45a charge controllers even if one of them were to malfunction, i would still have one left to do
the charging.

so, as you can .....................................


another quick note: not all inverters or charge controllers can be stacked. it is very important to read
oem manuals for whatever brand you're installing so as to get a handle on what steps need to be taken for
proper and safe stacking and what accessories are needed to achieve this. this is so that you don't
endanger yourself and your property.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ilenaira: 7:00am On Jan 26, 2013
Thanks for the reply George. I happen to be out of the country for about 3 months a year so i can get most things and carry it in my bags. But panels and batteries?, grin grin

F.y.i, Apollo solar do the T100 turbocharger (100 amps) as do Microcare in South Africa but they are super expensive. I think I have to do the dreaded stacking as you've suggested. I just dont want to make a mistake and end up frying expensive equipment. I'm actually starting from a clean slate hence the reluctance to buy 2 chargers

Thanks anyway and I'll be sure to share the build once started.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ilenaira:
@all, can anyone help me with understanding the port costs of importing batteries? I have 24 2v cells ready to ship but I have no idea of what to expect to clear it in Lagos.

The same applies for panels, what are the charges involved, what have people paid.

@George_D, have you ever come across a >90 amp charge controlller? I intend to have panels in series (48v) and parallel in a string. The output current will be 84amps (including 1.25 safety factor). Buying two chargers and connecting them in parallel is a expensive but there are not many cheap >90 chargers that I've seen so far.

Thanks

CrimeRe: Lagos-Ibadan Express Way: Robbery Experience TODAY by ilenaira: 11:59am On Jan 11, 2013
@OP, It is not for anyone to judge your action or inaction. To me, your story is an illustration of the selfishness that is common in Nigeria. From the robbers who victimise others in the same boat, to the drivers who refused to stop and help, and arguably, yourself in leaving the injured man behind. The problem is that the unwillingness to help by the passing motorists and you, in leaving an injured man owes more to the likelihood of bigger trouble from corrupt police, suspicious public and hospitals where money comes first than anything else. That means, it will probably happen again. sad
