Nope has a password lock

But it is just an 3 pin plug so can be easily removed and plug directly inserted into the socket . But makes a nice loud alarm sound once the load goes above alarm value before tripping the output if the trip threshold is met ( has time to avoid peak spurious triipngs)

I even asked the company if they will make a wired version but no plans yet

if you have money to spend and don't mind tinkering the smart sockets like TPlink and Samsung smart things also have a power threshold alarm and a notification on the phone ( need full time wifi though in house)

Exactly what i meant by bypassed... A wired version would have worked best.
Anyways, I'm just conducting research for future reference... I appreciate your input

Thanks to Bigrovar . .

you would never get close to the panel specs . . at most 77%; if you're lucky

no matter how the sun shines . . .

as a matter of fact; too much sunshine + poor ventilation = too much heat = reduced panel performance

I consistently get above those figures on my ground mounted array made up of mismatch of different panels from MyHome to Solarland non a tier one provider 240w x2 + 250w x 2 connected in series parallel. With a combined functional output of 960w I consistently do over 750w to 810w on a clear sunny day between 11 and 1pm. I have seen occasional pick of 900w before too.. But standard generation is way north of 700w on sunny days. Part of the reason for this is because they are ground mounted and face true south at 81 degree vertical tilt. A 4500w system installed on a carport with clear view of the sky and installed flat yet picking at 2.5kw is not doing fine especially when total generation stuck at 6kwh.. My 0.96kw system does 4kwh on a regular. Before talk about load, remember he uses a high capacity battery drained to 50% dod that's a lot of kwh that need be replaced. Something ain't right. There are folks on here with 3kw array cranking out 10kwh daily, some of them even hit 2.8kw and have the log files to show for it. Proper real time minute by minutes log files.

makavele:


Let me break it down for you sir . .

What do you mean sun intensity to calculate . . ? LOL

You be confirmed olodo

I need real life answers . . . So i go to my lounge; hook up a multimeter and see what is coming in . . . How simple can it get . .

I don't even take into account what the Charge Controller is telling me, i check voltage and current and resistance manually . . .

That's an overkill for practicality . . .

Back to you: Let's be honest and serious for once . . .

Even with a Yachi, Yingli, Solarworld, CanadianSolar or brazilian whatever . . in real life specs; you cannot get 91% of panel specs . .

That is the answer he needs. So if we go back to why I told you all to discard the manuals, now you see it.

Under STC, a 100W panel should produce at least 99.9W of power . . . but if you are basing your judgements on STC, you are headed for an

epic world of failure or regrets.

He asked a question, f*ck the STC; give him a real life answer . . .

if he gets above that, good . . ; if he doesnt, then he won't be disappointed.

Let's watch how we talk to each other. Let's watch our language and explain our point with respect. You made a major goof about current flow between charger battery and load yet no one called you names we all took time to explain and correct your misconception. No one knows it all. The pride of this thread is that we manage to build a brotherhood, an oasis from the general ceaspet of insult and hate that NL can be. Let's maintain the decorum.

Egbon pranil abeg drop me your mail or mail me at bigbrovar on Gmail I have some questions on Ipowerplus. The unit we have randomly throws up error 52 taking AC out offline until inverter is reset. This happens mostly during switch over from gen to NEPA but not always. If u have experience on such issues or about fixing those inverters drop it here so bad bad it can be filed into the knowledge bank

1stly . . i didn't even type the bolded at first; until something rather, somebody made me laugh so hard; i had to come back and type it . .
I apologize

2ndly, that was no major goof; cos like pranil said and I stand with him; it depends on how the whole thing is wired.
and like my other colleague said . . its' more of blind men feeling an elephant . . to each own his own interpretation . . .

3rdly, i have never claimed to be Mr Know it All or Mr Sell-it-All

4thly, The pride of this thread is that we put a stop to the 'asslicking' and "virtual genuflecting" and stick to knowledge distribution in a formal manner; as it is with other foreign RE forums

And i take no pride in saying it; this thread was practically dead and heavily commercialized; and too familiarized ; until I came through with my tough controversy; which would definitely hurt some of y'all's pride . . . but at the end of the day, we all take 1 or 2 things home. . .

Thankx

nothing happened to him. i guess he moved on to other products
for business reasons.

wow. Wonder if any of our dealers here could try to import the Zenith batteries . I am sure it would sell well

In the first place Voc and Isc should not be used to calculate the power output of solar panels. They are safety specifications, for the safety of the solar panels or your setup. So using them to calculate power output is misleading. Always use Vmp and Imp when making your calculations.

2. As rightly said by someone, the intensity of the sun matters

3. Most of the solar panels and charge controllers that come to Nigeria are overrated. The truth is they will hardly ever deliver up to 75% of their rated capacity. Eg if you buy a 3KVA stabiliser or generator, please don't use it to power more than 2KVA equipment or 1.5kW if you no want make e spoil

4. Lest I forget, if you want to measure actual power being delivered to your house, please use a multimeter and measure at the point between charge controller and panels when the batteries are empty and just started charging(and not when they are already getting full because the batteries will not draw maximum power when they are getting full and you might not be able to tell the real power capacity of your panels)

So to answer your question at rated illumination of 1000W/m2, please hope for 75% max power. If you get 75% with equipment bought in 9ja, guy you don hammer. 80% and above, hmmm, no comments but e go hard, real hard. And don't rely on peak power always average over some minutes even if it is 3 - 5 minutes

I have been following the intensity of today's posts with keen interest and I must say I echo you BigRovar!

My MorningStar TS-MPPT 60A is connected to a 4.5kw (15 × 300 Mono Panels) array just like Mr Olagunju - my yield today was 17.77kwh in Lekki. Lagos State and this was an average day with quite a few cloudy intervals.

This underscores the importance of a solid charge controller as I routinely do 21kwh daily yield on a good day when my batteries are deeply drained.

Please bear the following in mind - my panels are West facing at a ~30° slope so by no means ideal yet I get these results with a solid charge controller - I made custom settings to throttle my controller max charging amps to 55amps - it will routinely hold 54.4amps from 1pm to 4:30pm with only brief rests at 40sumtn amps when there is a lot of cloudy skies.

When I had my chinco EP Solar on this same 4.5kw array I would get say 45 amps very briefly as peak but EP Solar would generally stay around 39amps - the only thing different between 39amps & 54amps yield is a solid MPPT charge controller!!! - 15amps improvement and remember I am throttling the morningstar controller output to 55amps via custom settings so as not to boil my batteries - I have seen it easily hold 58.sumtn amps steady for 3 hours plus.

So that's it - Mr Olagunju probably needs a proper charge controller if everything else checks out - currently I disconnected my second array of 1.8kw which is connected to the EP Solar - I am keeping it as backup for when the rainy/cloudy season comes.

Thanks, i hear you loud and clear. Unfortunately i bought the chinco one myself. No blame to the installer. I will arrange for another one

Many thanks Mr Olagunju and you are welcome too.

With the pictures you have shared most of the house would say your installer could have done a neater job with the wiring cleanup especially with the changeovers/knife-switches inside the house but this is just aesthetics in the end

I also observed that he did not use the modular MC3/4 connectors to connect the panels in series and then parallel - to my eye the way he spliced the panels' positive and negative cables to the main trunk lines may not make for a firm mechanical connection - just something to check - if you could isolate each series string of panels and see what they are doing with a volt and amp meter and see if any string is doing much worse or lower than the others - further in the evening or after disconnecting panels from CC, try pulling the spliced wires apart - they should give no 'play' whatsoever i.e shouldn't feel loose.

The good news is that panel heating up and reducing output should not be a big issue in your scenario - you will also enjoy a cool shade under the panels in the afternoons.

I think you are pretty close to getting to a good place with your system - with a few wiring tweaks and a solid charge controller you should soon be smiling and reaping the benefits of your system.

One last thing is to check if your batteries are behaving close to spec i.e 48v 600ah - do you have access to a battery monitor? or you can just run a known wattage load for x hours and see how the batteries hold up - it may be that your batteries are lightly cycled given such a huge bank and the CC is just floating most of the day - but again in the pictures I saw the battery voltage at between 48.sumtn & 49.sumtn which is not a good sign so early in the night as it means they were not fully charged during the day or have been quickly depleted after sundown.

Are you simultaneously charging with PHCN or Generator during the solar charging hours? Is the surface of the panels clean and relatively dust free (if not wash them). Is the house or other object overshadowing the carport and shading the panels?

Just looking for what random factors could be limiting your yield

Thanks a lot. There was no load this afternoon because the battery was drained to 45% this morning. We charge the battery all the day and was not in use when i took the picture. Please what model is your morning star? Thanks

I have gotten 802w out of 1000w installation..... Sunshine panels for that matter

makavele:


Still not gonna get past the 77% mark

Different brands of mppt works besbt at different Voc. Epsolar 60A works best around 120V input while fangpusun works best around 60V for a 24v battery system . In summary...do the research for d right input.... Almost all mppt are 97% and above efficient

You guys made my day.
It's been a while since the thread experienced EQUALISATION VOLTAGE.
Abeg make una drop to float voltage Abeg.

@Bigrovar, you did well as an unbiased umpire.
Me Niyi, thanks for stressing the importance of premium mppts.
I have a 4kw set up with classic 150 Mppt. I usually harvest above 9kw when by batteries are hungry.
My peak performance has been 2800 to 3000w. But on cool days, I record up-to 4kw plus and never last for over 1 minute. It's just a flash.
Ilorin Sun is been kind to us for the past 4 days. Afternoon cooking resumed. All extra energy has to be used up.

This another confirmation @ makavele more than 6 confirms Argument closed..

Now I know where to check sun intensity...

People should stop using Chinco products performance to make conclusions..

If a US brand make a product 1.2kw they will rate it to 1kw
But Chinco will rate a 500w products to be 1kw...

I will just save more to get Victron charge controller jejeli

I just realised I have been off grid for almost 18 months.

My Trojan T105 are still giving me the desired result. But I ensure I never drain below 47.5V.
I am not sure I am ready to find out the consequences of doing so. Since the batteries respect me, I equally respect them by ensuring NO DEEP DISCHARGE and regular equalisation charge.
I maintained an float voltage of 56v which Is to ensure I have full battery for as long as I have quality Sun. I am aware of the effect on watering but that's the only way I get the best from them. Myself and Saipro discovered this method and has been working for us.

My Trojans are now 3.5 years old. Purchased June 2014.

I pray the price of batteries drop. I am not sure I can afford replacing my battery bank with the current prices.

So to answer your question at rated illumination of 1000W/m2, please hope for 75% max power. If you get 75% with equipment bought in 9ja, guy you don hammer. 80% and above, hmmm, no comments but e go hard, real hard. And don't rely on peak power always average over some minutes even if it is 3 - 5 minutes
