Step up to 48v dc, and the current is halfed... 34A dc.
On a 600Ah battery bank, that draw is negligible

Haba shey that your AC na old model 2hp wall unit brand ? My AC dosnt take up that amps but I always emphasize more on Oversizing PV array & a well sized battery bank to AC users especially those who run theirs at night .. Cheer's !

Will this solve the problem for good ?

Is it an MPPT controller ?

How much ?

Haha its always like that sometimes .. I had serious headache planning on type of split AC's to purchase then ! I ended up using 1hp split available then for bedrooms and 1.5hp ×2 for the sitting room solely to run maybe 1 unit when I have guests under sunshine.. So far so good, all has been working superb ! My power inverters are splitted into 2 basically for major and minor loads . Cheer's

Reprobate:
thanks for the prompt response.
yes i hv powered a normal 1.5hp ac + 1hp inverter ac simultaneously b4..inverter shows 61% load..
i couldnt wait and powered the 2hp ac..load displayed was 11% with only the indoor unit blowing..and jumped to 56% when the outdoor unit kicked in..battery voltage dropped from float of 58v to 50.8v..cc input is btw 550w to 650w..not a sunny day..
intend to keep an eye on the batt voltage..so it doesnt go below 48v...batts hv been having an easy life..never gone below 49.2v on normal use.its a highpower inverter

There in lies the culprits. Roy solar.. Its you again ... Bro your inverter and solar charge controller have conspired to murder your battery. Even if you don't use those batteries they would still die. The inverter will never be able to charge those batteries properly. They won't be able to give it proper absorption charge (14.4v at the very least) and 15.3v for 2 hours of equalisation at least once a month. You won't get that from your inverter. The charge controller is even worse. Fortunately you have a tubular battery so the situation can still be saveged. Get a different inverter one of the powerstar series from Must or felicity if possible, get a tracer series charge controller and connect your panels in series. All this would set u back over a 100k. It is the price for bad installation. Solar is not cheap. You can't afford to make a mistake because it gets even more expensive.

Gurus in the house...i need your opinion and help please

i paid for solar plus inverter back in January this year at a cost of over N700000 for which the installer supplied a 2.4kv prag inverter plus two GDM 200Ah batteries and three 300w flames mono solar panel with a roy solar controller so its safe to say that the installer made a very very good profit on my job because if I had bought all that myself and called him to just install, the materials won't cost me more than 525k as at then and am sure he can't charge me 200k for just installation

but i wanted to avoid issues so I let him buy everything and avoid "i am not the one that bought it, i just installed it" issues but unfortunately those issues i wanted to avoid
all came back now making it turn out to be the worst purchase i ever did in my life.

first off...i knew that solar was fishy as its mostly reading arnd 7 to 11A even under bright hot sun.

from day 1..i hardly got 20A charging frm the solar(frm my calc..900w solar should give upto 40A at 24v)...so even at full sunny day..once phcn doesn't bring light for a full day..inverter goes down arnd 6 to 7pm..now the solar charging is so bad that if nepa takes light frm morning, the inverter goes off mid day arnd 1-2 pm when the sun is at its brightest

just 6 weeks after installation, the useless prag inverter gave up..thats when i knew something was fishy 100%...the inverter would be supplying light to mains when in battery mode..had to take it in to warranty repairs.

now the inverter hardly gives 3.5 hrs backup down frm about 9 hrs when it was new in january(same load)..this is something less than 4 months old and has never worked for more than 7 weeks at a time without going nuts

usually nepa takes light by 12 midnight and bring by 4am....now even b4 4am..dis unverter would be screaming low battery and shutdown anything frm past 3am...just dissappointing for a setup costing over 700k

the installer is very nonchalant because i paid him in full so he doesn't seem to care. always forming busy and like he is doing me a favour to even respond to my messages

lesson av learnt so far is never pay any technician/artisan in full upfront and also never ever buy a prag inverter...never..dat brand is just useless!!!

can u believe that after the inverter packed up just 6 weeks after installation, it took this idiot installer another 6 weeks to show up and take it to the service center?

later...dey will say its village people when its just deir stinking attitude thats killing their prospects

if i had been on installment with this proud fool that installed this nonsense..he would have been forced to fix all this

now to why am here..any suggestions on how I can at least get arnd 6-7 hrs backup regularly?

because as it is...the prag inverter is crap(i mean i knw many ppl on luminous that has worked for years)

the solar is semi crap

now it seems the battery too is giving up

all these barely 4 months after installation that cost over 700k

ppl just don't have fear of God in this country

load is about 4 fans, 3 energy bulbs, 2 lcd TVs and 2 laptops

any suggestions on how to remedy this pathetic situation highly recommended!

thanks in advance

Just finally moved to my own modest house. Decided to finally take a chill pill on the race for the higher wattage and settle for efficiency on the consumption side. This allowed me to set aside some funds for putting a roof over my head all glory be to God. My 1.84kw panel is all the electricity I need for now. I will connect to the grid once am done with some finishing touches to the house.. I generate enough to provide me 24 hours electricity that meets every basic needs refrigeration, laundry, light, TV, kitchen stuff.

The house runs on LED spot lights the highest being the single 12w kitchen lights. Over night amps draw before sun rise is 75AH from a 24v 200ah battery. I had time regig my setup.. Power drill was a life saver.

Malevonent:
These are great results KieKie

The question you seem to be so cleverly dodging is what is the exact size of your PV array that is very similar to @Durodee's? 1.5kw? or 1.6kw? or 1.8kw? or 2.4kw? that routinely generates 8.9kwh daily yield ?

If you have a 1.53kw array like @Durodee then we are looking at a superlative 6times PV array size daily yield which is superior even to the best known routine results from high sun intensity and long solar days areas like Australia.

I am asking you to tell us the exact size of your PV array not to throw shade but rather so we can put the yield results in perspective and any newbies can set realistic expectations.

If you are daily generating 6 times your array size on a regular basis then we all need to come learn at your feet and pick up pro tips and tricks to use in our own installs




ahha, good you spotted his carefully worded response , i noticed but decided to ignore, but as you hv broached the subject.................................

am fairly certain his array is oversized, why he refuses to state the full capacity of his array, am really clueless , makes no sense at all.
my array is 1500w on 24v inverter, hooked up on 60amp epsolar, hv been adviced by the house to ramp it up to 2000w or 1800w to squueze out the the remaining juice from my setup.

this i hv decided to do this easter, will add 2 x 250w panels and change my setup from a 2 strings of 3panels to 4 strings of 2 panels.
max instantenous wattage i hv observed is about 1320w, i must confess my installation isnt optimal,,,as i simple used the existing roof space, hopefully the extra 500w will take to to the promised land of squeezing out 1600w fromm my cc as kiekie

Oga Niyi,
Good morning , I hail ooo ! All this your long thesis sef ... All I said was simplified , you have been to my place and I have also been to your crib and I must say that in all solar calculations we have losses we must contend with ! Question you asked and expecting raw figures has already been answered by Oga George D few pages ago when he detailed about "Oversizing your PV array" against rainy days ceteris paribus & that was a major reason why he gets charge current even when his panels are dusty ! Juo also gave you some tweaks which most will say its unethical to load an mppt above its required wattage . we must not type about personal experiment or tweaks which worked for us here as it might not work for Mr B due to factors surrounding his mppt brand etc ...
Juo has also mentioned it in past but most will always argue its wrong but i just smile ... I discuss better with most who engage me in qualitative chats about their PV yield . Richmond will also tell you that "its most of us day to day business and we feed our family on this" ..
In summary, I replied my total PV array as MAX 1600w "loss inclusive" as I have always been a 24v fan like Oga Durodee and utilise my panels to peak ! I get 50-62a cc always and most sceptic pals will still tell you that your mppt might blow up on the short run due to operating at max , over heating et al but mine smiles daily at max .. Cheer's

^^^ Are those not brand new items you are selling up there? And you're saying *NO WARRANTY*

Jame, James, James, how many times I call you ?

Funny when at investment stage the wifey will be like why are u spending so much. But at the benefit stage they can't do without it

Mehn no sun here for days now.

Maybe cos live just about 1 minute from

the atlantic !

GeorgeD1:
today's sun is really something else.

i pray for more sun hours like this for us all.

20.8kwh and still counting!

chris81964:
Do you really want to go there James?

Buy from people with brick and mortar shops. I had a nasty experience with him too. I paid for new batteries and he delivered used batteries and then denied that he sold me used batteries. The batteries had scratches and broken vents. I have actually blocked him on my whatsapp. He has no shame or scruples. Lesson learnt.
