Thanks for the help. Would look into flexmax 80a . Any idea on price range

samnaija:
Are the panels on the large size. Because the epsolar states 1600watts for max power. And the 8 in number. Do you suggest I return them for smaller sized panels. Will appreciate need to make a decision.

samnaija:
The panels 320watts Voc is 45.07v. They are 8 in number. Tnks

DMerciful:

samnaija:
Guys a 24v 500ah system. What's the best panel configuration. If your are going to use12/24/48v epsolar mmpt charge controller 60a. The max power is 1600 watts for 24v system. Is it better parallel all panels or double the PV volts.

Hello team.

Found this, but not sure of it usefulness

zinaunreal:
everybody is focused. But ive noticed you people still don't want to ignore a few comments on quilox so continue showcasing your immaturity here. Rubbish. What would it take for you not to comment and move on. I cease to comment any futher. If una like start employing people on this thread like say na company. Na your forefathers get am

davodyguy:
Wow. Yours is super. I'm currently doing 200watts. Its safe to conclude that I'm losing batteries, cos the 10amps can't do anything.

My wife is on my neck and since we work to take care of the family.

If the batteries start showing, signs of being low, I'll put on the gen.

My aim is to increase my system by end of march, 2018.

I'll get 2 more 300 watts panels to take my system from 600watts panels to 1200 watts panel

Hello chief niyi and Dmerciful

It rained heavily last night and the effect is seen on the sun right now, very poor now in Lagos

My Panel is sending 3-4Amp to the batteries.

I want to use the inverter now and still allow the Panels to continue to charge. My question is if I load the batteries now, will the load be on the batteries by draining them or it would be like normal electricity that charges batteries and also supplies power without depleting my batteries?

I hope you get my question

NiyiOmoIyunade:
I saw your prior post RE: Flames panels performance but I decided to keep quiet on it as many factors from battery SoC, mounting angle to orientation to shading to ambient weather, temperature and cloud cover and as you rightly pointed out quaity of CC used e.t.c affect yields.

I have had several opportunites to compare the performance of MorningStar vs. EP Solar side by side and the MorningStar consistently gives about 30% extra yield but bear in mind it costs twice as much sha MorningStar will lock to a Max power point and maintain amps output even as cloud cover e.t.c changes but EP Solar would just be jumping up and down and picking a lower yield point to settle on.

I was able to sample the Fangpusun series thanks to JUO and they do give far better performance than EP Solar as per MPPT tracking and amps output but ultimately I decided to go with my trusty MorningStar of which I know it and its capabilities in and out and have also attended a lot of their technical training e-sessions. The Fangpusun interestingly comes in at a lower price point than EP Solar.

Talk to JUO for supplies of the MorningStar or Fangpusun as with him you are almost sure to get the best prices available locally. If you wish to import a MorningStar CC and save about 20k with a 2 week wait then I may be able to help you but you have to pre-pay

You will always do better with the premium vs. china origin CCs but don't forget price vs performance. Someone here also has been offering the Midnite Classic at what seems to me an impossible price so you may wish to explore that route... but before you buy a new CC be sure to eliminate other system bottlenecks that may be giving you poor performance

It appears the vaster majority of people here are Midnite CC fans and they swear by their Midnite's performance but as for me and my house, we will stick with the MorningStar we know and love and trust

Barezzi:
This is not entirely true, as harvest is proportional to usage.
You squeeze every juice from your array cos house energy usage far outweighs production, hence your fantastic efficiency numbers.

zinaunreal:
it would have been wise for you to keep shut and get on with the TB discussion rather than lecture us on what we already know Mr Minister of Education. Taking the heat off sometimes aint bad. Youre asking for correlation. When ever you drive from lagos to portharcourt don't stop to take a break and eat eba and better soup keep on driving till you suffocate. Coz you own a car and others use public transport doesnt make you a robot. You must divert to eat. Youre asking correlation

Youve actually dragged just a few comments that isnt even up to four peoples opinion and made it a case. Maybe na you own this thread i guess. You can eat the thread then.

NiyiOmoIyunade:
This then is the price vs. performance paradox that we face in deciding to go with the Premium or Value offering.

KieKie can attest to how many times we haggled bitterly over me trying to get a good price point for supply of Solar World panels over the last 2 years - the guy would give me a quote and I would squeeze him hard for more discounts until he would abruptly end the discussion in frustration.

Using advertised prices on this forum for the larger size 300w range panels, I estimate the price of Premium Tier1 to at least 260naira per watt and a good Value Tier2 to at least 180naira per watt.

If I give the Tier 2 60% efficiency and the Tier 1 STC 77% or let's just say 80% I am still looking at the Tier 1 coming out more pricey. Again I would say 10 years forward is the usage horizon for solar panels because one would always want to upgrade to the latest tech even if the product in use was still performing.

This is the dilemma I face every day in making buying decisions for myself and clients especially those with a large budget. I have come to decide that it's mostly an emotional decision in the end hence I bought two MorningStar units for myself because I believe I can rely absolutely on them even though one Midnite Classic 96A may have done the job at 60% of the cost but simply because of the remote possibility of fan failure in the Midnite I refuse to use it.

Pecca:
What integrity? Integrity entails sticking to your words. Tell me one thing this Mr Integrity has said and stood by it. Is it his boast about foreign hospitals? His asset declaration? Fighting Boko boys from the front and defeating them in 3mnths? The man na bad product jare!!

davodyguy:
Thanks

Kindly advice on the best position they should face.
I plan to get another 300watts Panel

davodyguy:
Yes, that's why I asked if what I'm seeing is at its peak

Inverter 900watts 12v
2nos 200amps Gennex Gel batteries
40A E-Smart Charge Controller
2nos 300 watts Panel

From 8:00am to 2:30pm with sun, the best I saw was 27amps dropping into my batteries.

Ha e I been scammed?

davodyguy:
I don't have this equipment

Ijeoma660:
Please who can explain this phenomenon.

I experienced this upsurge about two days ago before midday. It kept tripping my CC to Battery bank outgoing breakers. I kept closing it back, then it tripped the PV to CC incoming breaker. After which I allowed the system to relax.

PS: I looked out of the window and noticed the sun wasn't as bright as there were scattered low lying clouds in the sky. But the sun's intensity was so intense through the edge of the clouds with shadows showing clear and distinct outlines around objects!

Still wondering why...

NiyiOmoIyunade:
The plan is not to need new batteries for the next 5 years at least.

Fingers crossed on how the future will actually turn out!!!

If I can get battery longevity results like Oga GeorgeD then I will be a happy man indeed

NiyiOmoIyunade:
Your observations are correct same as Oga KieKie - Flooded batteries kind of have lower voltage profiles than sealed maimtenance free batteries and their Voltage vs. State of Charge charts typically reflect same.

I also noticed that this apparent low voltage is more pronounced in the Mercury Flooded I first had than in my last set of US Batteries for example but I have no hard data to support this.

Interesting that you also are getting disillusioned with Flooded batteries as a quite a few people have been on here - for me Lithium is the next port of call once I wrap my head around all the complexities of a BMS and battery balancing.

To eliminate undercharging issues with your Flooded battery bank please Can you confirm that you give your batteries a proper daily charge? What is your absorb voltage setpoint? How many hours do your batteries spend in absorb daily?

Currently I have 16 pieces of 12v 200ah Gel batteries in a 48v 800ah setup - my voltage generally stays around 50.6 worst case by 6am in the morning. If the Madam had used microwave a lot the night before or the 2hp sitting room AC then I could see 50.3volts - once on a cloudy day where I could not finish absorb and still had heavy overnight usage, I saw 49.75volts by 6am in the morning and mind you I ALWAYS use the 1hp bedroom AC overnight.

So I remove anywhere between 160ah to 260ah between 6pm and 6am daily from a 800ah bank and the voltage stays within the 70 to 80% State of Charge mark.

So far so good excellent batteries and they were sourced from ICelllPower through JUO.

kiekie1:
I typed 100% ! Its due to distortions you get especially when you load above 50% .. Its not really obvious for those running average loads , its ruggedity can't still be compared to transformer based pure sine wave inverters.. Thanks!!

kiekie1:
Ooo sorry for the disappointment on your konga supplies .. You are more safe because you paired up Gennex hybrid "par a & b" .. Its a bit more affordable considering the procurement cost of a 10kva schneider , victron etc without adding extra cost of mppt yet ! It exceeds a million to be factual ... If you operate within safe load range , your inverter system should serve you for years not minding its not 100% pure sinewave !! Cheer's

earthrealm:
wow, if a transformerless 5kva axpert system has 45w idle consumption, makes me believe the 135w idle consumption rating for the 4kva prag/mustpower.
the axpert is really a master piece, i wish it could handle my resistive loads, the wide input range is a big plus 85v to 280v ac, and massive charging current

Barezzi:
About 45w each if I remember correctly. When i get home next month, i'll confirm.
About 90w*13hrs=1.2kwh by daybreak. Not much, considering my pv array.

Hot water. This particular area nearly gave me high bp, until Dapsyra's tweak!
My house is fully off-grid.

How's your system treating you bro?

Barezzi:
Yes, I have 2 Genex Axpert inverters in parallel mode.
It carries everything i throw at it, no issues so far. 5 months and counting!

Each inverter has a 2.6kw array. They've been churning out amps like a demented coyote on heat.
