Thank you for that reassurance. It was sent yesterday via DHL.
How was the charges, hope no DSS, FIRS, police et al issues?

No charge whatsoever.
It was delivered to my home address.

Better then, thanks for sharing

UPS got me very 'afraid', I try to avoid anything to do with those guys! Post office or nothing principle was activated over two years ago.

Installation I commissioned yesterday went today to find out that anytime the solar system try to charge it will be cut off n on n off at Interval resulting to non charging
The system is a 48v system and the solar panels re connected in 3 strings 12pcs 300w panels connected 3*4 with 8pcs 200A batteries
So the inverter display indicates 96v n 1.6kw from solar arrays but cut off n it shows 120v n 0kw indicating the battery not charging
The inverter is 5kw MUST Hybrid Inverter pls is there anything am missing or does it mean the inbuilt mppt controller cannot convert the access voltage? Pls I need help

Read the manual of the inverter very well, likely you are either missing the PV voltage range or the setup of the inverter is wrong

Good morning house.

Please how good is sunshine solar panel. Someone gave me 250w 24V for 35k.

they are quite good. I stuck to them (my sunshine dealers ) because they have changed 3 panels which got damaged at 2 differnt occasion during haulage.

Anybody here installed or using Mustpower PV3500 series before here?

DMerciful:
Read the manual of the inverter very well, likely you are either missing the PV voltage range or the setup of the inverter is wrong

The PV voltage is range 64-145v for 48v system which am installing
I have gone through the manual the only thing I couldn't find is where to select battery type as it's on SLA by default and am using AGM battery
I even brought another inverter same product from my shop n test it in the same client house it still cutting off charge from solar array
The electric charging system is perfect but something keep disrupting the mppt system
I have contacted Mustpower factory in China but I have to wait till Monday to get assistance from them

Hello, what is the maximum input current for the inverter(pv section, we know d max pv voltage is 145v, u need to know d max input current too)?
Go back there and start with 3*2 config and see what happens. If it works fine, go to 3*3. My guess is, maybe 3*4 config current is high for the pv input of d inverter. Good luck.

All in one street light is howmuch fir those that have??

Apologies my Oga.

It's lithium battery powered street light, and yes all you need is a pole or a wall (if wall is out in the open without obstructing the sun from getting to the solar panel). A friend contacted Schneider some weeks back for their pricing and they told her 676k for one

There are also some not that high...check the link below:

https://www.nairaland.com/390522/solar-energy-complement-fta/478#73202177

Apologies my Oga - my offline duties tied me down for a bit.

Please see the diagram below using a 24v example for simplicity - it is nothing revolutionary really.

The thick unbroken lines represent the standard connection any one would do.

Batteries A and B are in series same as batteries C and D. The two battery banks AB and CD are then connected in parallel to double the amp-hour capacity.

The new thing is those two broken lines connecting the +VE of A to C and the -VE of B to D - essentially putting the batteries in each matching position in parallel with each other. With these the fates of A and C are now bonded together same for B and D - they will maintain the same voltage with each other always and also banks AB and CD will also balance each other out naturally.

With this config, one may introduce just one balancer for the entire bank vs the one per bank people usually do - with this trick, I have successfully used one HA02 balancer for 24 batteries connected 4 in series and then each 48v series bank connected to make 5 sets of 48v banks in parallel with the added wires for balancing per the diagram.

The only caveat as Oga Saipro pointed out is that one battery failing could bring down all the others in parallel with it.

The balancing wires do not usually carry any current except one battery goes out of sync - 4mm gauge is the minimum but if you can match the gauge of the main DC cables then all the better.

I am still studying the longer term effects and some authorities will bring up all sorts of horrors and dangers and say fusing is mandatory. I am happy to hear all the critiques and any fors/againsts.

My solar journey so far.
( All connections were done by my humble self with good amount of knowledge gotten from this forum. )

Earlier this year I decided to add solar component to my inverter of 4 x 200A battery (48v 200A – 9600W).
So I connected 12 units of 250w solar panel (3kw) with 80a Flex Max Outback CC.
I later increased my battery Bank from 4 x 200A
To 8 x 200A bank (48v 400A) in April this year.

Mistake Nr 1:
When I was still using 4 batteries I noticed 1 of the batteries reading below 11v, so I changed that single battery and added the new battery into the bank. (March this year)

Mistake Nr 2:
I bought 4 extra batteries in April to increase the capacity, thereby mixing 4 + 1 = 5 new batteries with 3 old batteries Totaling 8 batteries.

I later increased the Solar component to 18 units of 250w panels (4.5kw) thereby maxing out the CC capacity of 4kw for 48v setup.

In November this year I noticed that the batteries drained to quickly, although the inverter had neva beeped, I decided to check the batteries in the morning and noticed the older batteries were around 10.8v – 11.2v.

Having learnt my lesson I quietly bought 12 new SMF batteries (6 Genus 6 Bluegate batteries) this December (48 x 600A), I also decided to buy battery indicators to know the voltages of the batteries at all times.

I have also increased my solar component to 24nr 250w solar (6kw)
18nr 250w panels (4.5kw) are connected to one Flexmax 80A Outback CC, the other 6nr 250w connected to the second Flexmax 80A Outback CC.

So basically I have a 6kw Solar panel array with 48v 600A battery bank; 2nr Flexmax 80A CC; 3nr 48v battery equalizer; 12nr battery indicators; 5kva Must Power Inverter.

Observations coming in the next post…

Pix 1: Solar Panel array
Pix 2 battery connection with equalizer and indicator
Pix 3: mounting if the CCs
Pix 4: Final installation

@NiyiOmoIyunade thanks so much for the diagram, I trust u will definitely respond


Note: I just noticed that, this is the way I wired most of my batteries bank. For the 24V setup, I use just one balancer and 2 volts reading indicators instead of 4.

you bought direct from the distributors, or from a seller here?
if dealer pls gimme their contact or link

Observation Nr 1:
Avoid the temptation of mixing old and new batteries u will eventually regret it.

Observation Nr 2:
Try as much as possible to have a battery voltage indicator connected to all the batteries so u can always see the voltage of each battery and know when one is under performing so as not to drag the entire bank along with it.

Observation Nr 3:
I am still wondering if one can truly sustain on solar. (My saving grace is that when PHED lite is on it can stay as much as 2 weeks without blinking but when it goes off it takes another 1 week for it to be restored.)

In Port Harcourt during the raining season harvest was very very low. My 4.5kw solar array usually puts out about 5kwh – 8kwh on good days and as low as 3kwh on bad days.

Initially I tot there was something wrong with my connections but on some VERY rare occasions when the sun shines all day it puts out about 14.5-15kwh with instantaneous power at average 3.4KWp - 4.1KWp.

Since the coming of dry season here in PH, my KWp has reduced to Max 2.6KWp for a 4.5kw solar array but the daily harvest moved up to about 14.5+kwh.

I am a little confused coz I was hoping that my KWp will remain high now that the sun is here

Pic 1 & 2: are from today and yesterday

While

Pix 3 & 4: are from early November during tbe raining season.

Is it safe to assume that Kwp is better during the racing season than during the dry season?

Regarding harvest, several factors affect yield.
1) The position of the sun in the horizon. The sun moves from tropics of cancer to tropics of Capricorn and since your panel is fixed at a particular angle, harvest will be affected esp if you panels are not facing the optimum angle of 6degree south.
2) During raining season, though cloud cover is more however the atmosphere is clearer from dust particles that affects the amount of light incidenting on the panels. So instantaneous harvest may be higher but average daily harvest may be lower than dry season. The panel's also runs cooler during raining season and cooler panels harvest more
3) The state of your batteries(SOC) at dawn also determines harvest. There is a possibility of consuming more during dry season from dusk till dawn due to running AC to overcome heat and as such creating room for more harvest.

I see that you still mix different brands even after the initial battery failures due to batteries of different ages..Kindly clarify

Watchout for the impact of those equalizers or balancers...I have a strong conviction that they cause more harm than good.

They are all new batteries.
Just that 6 are Nexus while 6 are Bluegate
All are SMF VRLA batteries and they charging profile is almost similar Absorb 14.7v; float 13.7v

(I basically choose the midpoint in the range of the batteries)

If one could,better to buy same brand, same batch cos they do have different internal resistance no matter how little

Yeah .good point on not mixing old and new batts.
Recall i planned replacing the 2 suspe ted bad batts in my bank.
Thank God for the led voltage display.

After changing out the batts .i observed the 2 new batts i put now had voltages of 14.5v and 15.7v respectively after about 10mins of charging on phcn. And the other 6 batts were abt 13.6v
Note float of Long batt is abt 14.6v...i just knew that the high voltage will dry out and kill the new batt in no time...so i quickly re installed my old batts...n kept the 2 new batt for another ops.

I also noticed 1 loose terminal on 1 batt..that particular one was reading 12.1v when all the others were at 10.5v and 11.5v respectively....hence i suspected the loose terminal may hv been the cause of the higher voltage and also why it wasnt contributing its all to the bank.

Am also considering removing the batt balancers after further observation..n install my copper bus bars.

congratulations on the bold step bro. however, after soaking the garri, you still made a mistake. Dmerciful just pointed it out

NEVER mix batteries of different brands; even if they are same capacity and technology. even if they were manufactured the same day and time. They can never ever have exact same characteristics.

few manufacturers do state it in the leaflet that comes with their batteries. Mpower just re-branded their battery. The new ones now comes with a leaflet with battery do's and don'ts. one of the do's is "always use batteries from same manufacturer within a bank of multiple batteries"

it would've even been a little bit manageable if it were maybe, 8 from one brand and 4 from another brand.
nevertheless, mixing batteries from different manufacturers, is just a NO NO

Also, most times, the suppliers doesn't help matter. If a client demands I supply him 12 batteries. if 12 batteries of same brand are not available at that moment, I'll simply tell him to either go for 8 or just wait.

But then, I've discovered that even most of them don't know any single nothing. They just know "pay and I'll supply". whether you're buying 5 different brands to use on one bank, they don't know the consequences

yet, even those that are fully aware of the consequences will still go ahead with the transaction... after all, what's their business. tomorrow when you start complaining, they'll put all blame on you. that's when you'll know that asking for warranty from our dealers is like asking PMB to resign...

It is well o
