Hello house,

Please i am trying to install a solar panel system for my parents, can you recommend a good solar installer in Ilorin?

Secondly, I want to ask if anyone can help with the schematic drawing for hybrid inverter connection. I am not an expert but I try to read up, and from my readings, it seems that the connection of solar hybrid inverter is different from the normal solar-inverter connection.

Thirdly, I assume I don't need a charge controller if I am using a hybrid inverter...please help clarify.

Lastly, what is the recommended cable size and type for connection from the panels to the inverter....this is so that if I don't get a recommended installer, I can at least monitor the one I can manage to get to ensure a good connection.

Thanks house.

wow,long time bro...you have been scarce.
only 4.5yrs, i tot these guys were indesturctible....not much difference btw them and smf
did they just die suddenly, or a gradual reduction in storage?. did you try draining all the electrolyte, flushing the internals with clean water, refilling with good electrolyte and charge??

yeah solar biz in naija is not that profitable, with 10 to 20% markup in prices, having to replace just 1 battery will wipe out all your profit, if care is not taken. and battery waranty is an iffy issue... cos the user may have abused it knowingly or out of ignorance, and blame you if it fails .you may consider listing out the equipment and let the client go buy them himself, and you charge a flat fee for installation

bigrovar:


The unit I got is the 225L single door. It uses about 50w peek power but that varies it settles to around 40w. The down side is it defrosts very fast... but the up side is that it can conveniently be left to run longer period without damaging your battery.

Good morning house,

Please which of this product is best for a 48V system (Total Voc of 132v)

1) Midnite Solar Classic 150 Charge Controller 150VDC Input MPPT
2) OutBack Power FM60-150VDC FLEXMax 60 Charge Controller
3) MORNINGSTAR TS-MPPT-60

Any other suggestion welcomed....Once bitten....!!!!. Prices are welcomed as well.

You nor see "It's just a flash" for there abi . . eyes dey pain you man
If i tear you something . . .

Dam5reey:


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 have been using the BLS 12/24v desulfator since 2011 - the advertised method of operation is some sort of radio frequency signal sent into the batteries to break up sulfur crystals - I doubt if it is the cause of the issues with your inverter - the kind of desulfator myself and Saipro were talking about were the electronic pulsers/desulfators which send out very brief high voltage jolts into the battery to break up the sulfur crystals.

The issue with your inverter seems more like something on the load side or an issue with the inverter board or some sensor on the board.

Have you considered that you might actually have an intermittent shorted wire or similar issue in your house making the inverter sense high load sometimes? One easy way to isolate this issue is to install a 10amp AC breaker e.g ABB or other good brand on the AC live/positive side of the inverter output - I am assuming here that your actual loads never exceed 2.4kw or 10amps at 240volts AC - if that breaker ever trips where your real load based on equipment you are running is under 2.4kw and allowing for surge current, then you definitely have a shorted wire issue or there is some load coming on somewhere in the house that you are not aware of e.g iron or microwave or heater inadvertently plugged to one of the power sockets the inverter is powering.

In any case, with the breaker attached, you have effectively set a load limit on your inverter - a 3 to 4kw load should trip a 10amps breaker, a bridged wire/short circuit scenario will definitely trip the breaker - with this you can easily eliminate/confirm the inverter as the root cause of the issue.

i have a 4kva 48v muspower inverter with a desulphator hooked to it. the fan only runs when the temp hits 64deg, and sometimes when desulphating.
yeah, it doesnt like being charged by then, probablly cause of flunctuating voltge or frequency....maybe diesel gen with more stable output wudnt hv the same effect.
8kva HT gen output isnt so clean jumps around intermittently from 212v to 235v...n that affects the inverter....what i do is to lower the charging current to about 22amps....and its fairly stable at this seting, if i get greedy and want higher amperage...the charging trips/fluctuates off n drops to 7amps, 2amps, 11amps etc..

my only grouse with it is the high internal consumption - wch peeps here say is upto 100w for the 4kva models and above

NiyiOmoIyunade:
For the 4kw/5kw and above the big fan on the AC end/opposite the battery end of the inverter seems to be always running. I keep mine on the outside balcony so the noise doesn't really bother me.

For the 3kw and below, the fan only kicks on when the internal temperature rises to about 60 degrees C and goes off as soon as the inverter cools down a little. The fan in these units is a lot quieter.

Considering its a chinco inverter, I am undecided which I should find more reliable - the always on fan or the one that kicks on only at a particular temperature - I can say though that I have some of them in service for years now and never yet needed to change a fan and of course the load carrying ability of any of the units is outstanding - I run a 2kw microwave and 2hp AC off the 3kw unit (not simultaneously of course but I do that for the 5kw sometimes ).

Where I find them very unreliable is the charging function from the mains or generator - very finicky and prone to spoiling in a short while - I have an unverified theory that the charging function fails very quickly when using a pulser/desulfator on the battery bank the inverter is connected to - perhaps the internal components are sensitive to the transient high voltage that the electronic pulsers/desulfators put out.

Hello House,

I have being following this thread for quite a while now. Finally decided to do my solar project. Intend to hit above 6kwh from start. I need a trusted vendor to do this with. After seen a lot of guys here. I intend to pitch with zeestone99 based on your recommendation on his work quality and after sale support.

Can anyone kindly advise on his commitment especially those he has worked for?

kiekie1:


Its exactly same Dam5reey posted above ... It actually reads DC voltages (120vdc max) .. I have few units remaining if interested !

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.

A blessing in disguise? Maybe. A terrible loss? Definitely! God will replenish your pocket and move you to greater heights (we Yoruba say, "aafin oba to jo'na, ewa lo bu kun" )
