You probably need to oversize your array and perhaps tweak some other parts of your system too e.g go to 48v nominal

You have squeezed some spectacular results from a very lean system but at some point you have to just get more capacity to cater for the 'rainy day' literally and figuratively.

Of my 7.6kw PV array, only 3kw is enough for my day to day needs including heating and 24/7 refrigeration, the extra 4.6kw is a large allowance for poor weather and my almost compulsive desire to run two ACs nearly 24/7 no matter how good or bad the weather is.

I have plans to upgrade but they are some issues I have to consider. First I have 2 batteries that have refused to die.. There is the economic guilt of discarding batteries that are still waxing strong since I can't mix them with new ones. I also have limited roof space. Best I can do is a 2.4kw pv system which might still not be enough. Increase in capacity would lead to increase in consumption which would lead to another equilibrium and bring back to square one. There is no change I am increasing to 7kw.. Due to space considerations. For now I just have to use some of those nepa saving all year round to pay for fuel. 6 gen hours a day is enough to fill any energy deficiency.. I a week or 2 the sun would come back from vacation.

yeah, the rains are terrible, imagine seeing 100w/3amps from a 1500w setup..when its raining, so even if one has the funds..to get upto 10amps one needs to triple or quadruple his panels,the economics of doing that doesnt add up, as irritating and repulsive as it is to me, due to limited funds,, wud rather run a gen for 3 to 5hrs as need to keep my bank above 48v, like bigrovar said, i doubt this bad weather can last more than 2 or 3wks more

you could sell off the batts, am certain people would rush them if the price is low enough, its a miracle your 2 batt setup has survived this long, guess you aint married, or madam n the kids hv thoroughly understood the system, or you installed some non-human/emotionless control tech

Saipro:

In theory, never try that.

In practice, almost every solar enthusiast I know who's used AGM (and had dead batteries) would have either wondered about it or tried it. I've done both. Hit or miss, more misses than hits (let's say 15% success with limited extension of battery life and a very real risk of battery explosion). I witnessed poorly sealed caps pop off with such force as to displace a spanner.

At best, a risky experiment. I can't stop you from trying it but I can give one really good piece of advice: have 911 on speed dial.

Before I knew of this forum, I gave my set of 200amp telecom batteries to a battery charger for repair because they were not holding charge. He filled it with diluted acid and sealed it up. We first noticed the pervading smell of acid on return but worse with charging the batteries, later one could also dance to the music of boiling liquid inside the batteries!
It was a disaster waiting to happen. I learnt my lesson sha!

There is another key part of the puzzle which is having a suitably sized battery bank - one rule of thumb is to size for 3 days of autonomy - in an offgrid scenario where my daily usage (evening to morning) is about 150ah (incl. 1 inverter AC overnight) and I can generate 300ah to 400ah of power daily and on a bad day say at least 100ah to 200ah, I literally do not care what the weather is or what the sun is doing.

This size of system does not come cheap however and it may be more economical to run a Gen to meet any temporary power gaps. I am fortunate that I never had to pay for any solar panels I have, they were all paid for by my esteemed clients all I had to pay for were inverters and batteries and I got a super deal on my 48v 800Ah battery bank thanks to JUO.

The bold part is where the weakness of lead acid battery rears its head. I tend to ensure that a battery bank gets fully charged at least within a 24 hours cycle. This is plus shallow depth of discharge is why the battery is still doing fine and refusing to die. Keeping the battery in a partial state of charge for higher than 3 days will eventually cause sulphation little by little (this is just my fear sha so maybe I am wrong) I tend to limit my consumption to what I can sustainability generate back into the bank rather than storage capacity.

@Kiekie.. Do you have any client using these type of high voltage inverters. Just curious.

Three days autonomy essentially means you have enough battery storage for your average daily consumption for three days straight without any recharge or power going back into the battery.

Effectively, you are cycling the battery no deeper than 35% discharge daily and this without even considering what your solar panels can put back in.

Sulphation during PSOC (partial state of charge) is largely misunderstood - a battery that enters the 80 to 90% recharge window (1 hour or more in absorb) daily will suffer no sulphation damage at least not in 3 or 5 days. Most damage occurs when the battery is deeply discharged and left that way for weeks or months - anyone with properly sized panels will never be in this scenario.

The challenge is people not in the know acquiring lean systems undersized for their actual usage so that they only get a full charge on a very sunny day with light houseloads and their batteries are routinely or perpetually in a partial state of charge.

So the proper size for solar panels is the size that after allowing for losses will run your average day time loads AND fully recharge your previous day's battery depletion AND bring your battery into at least one hour or more of float on a daily basis. The proper size for a battery bank is one where your average consumption for one day takes no more than 30% to 40% out of your battery.

For panels, one must upsize whatever wattage derived from the above by a factor of 20% to 50% or even more to cater for bad weather and performance degradation. For batteries it is a delicate balancing act between maximum longevity/cycle life and the economics of battery replacement.

My philosophy is to perform all the above calculations assuming no grid availability - any power or assist from grid or Gen is entirely opportunistic and can only further sweeten the equation.

@Kiekie.. Do you have any client using these type of high voltage inverters. Just curious.

Yes Sir! I recently supplied Emzor pharmaceuticals the 10kva/180vdc spec . Its well known that solar hybrid designs are mostly within 12/24/48v design ranges nowadays but if you need longer backup for uninterrupted online applications or for higher rated loads and grid supply isn't really a critical problem, most organization/parastatals still use the Indian inverter designs because of lower cable guage and charge current for its batteries... I only advice they are installed with specified battery balancers for proper battery management and longetivity sake ! Cheer's

Hello house.

today I decided to give few weeks 'off-duty' to my fangpusun 80A and keep it against my upcoming upgrade from 24v (2250w) to 48v (4950w), I replaced it with fangpusun 60A earlier reserve as backup.

I was handsomely surprised that it output 3.5A over it's rated capacity for about 15s. before now, I always believe it is limited to 60A input / 60A output. however the inputs as at the time of instantaneous 63.5A was 42.5A.

And for fans of ff60 or ff80 (fangpusun flexmax)
I think we should be happy its doing it's job despite these horrible days of solar harvest.

I will like to know if any diy guys in the house has observed any other brands of CC with this over amperage mistake.

@ efuro,
I observed the same thing when i was using a 60A Fangpusun.
I have it secured in my box of critical spares...I may consider selling it soon.

Words on marble! Lemme quote it for posterity.

I always advocate:
1. Size Solar Panels for daily consumption+system losses weather (24hrs)
2. Size batteries for night time consumption only (5pm to 7am) This should represent about 30% of battery bank capacity.
From you submission below, i have reviewed (2) above.

I fear for my current bank as only once have I crossed 10% use. It's a paltry 200AH 48V but so efficient are my nighttime devices that fans, TV and lights still can't punch past the 10% mark unless I have guests.
Shallow cycles have a demerit too, particularly with tall batteries.

By the way, I made a harmless post right after durodee's own. Got banned for probably 24 or more hours and got my post hidden (not deleted). Sounds like the work of some overzealous moderator.

Impressive customer service. A few weeks ago I received an email, advertising the prices of solar panels. He had LG Panels at super competitive rates. I asked for a data sheet and he sent them. I told him I would buy. Last week I requested an invoice. On Thursday I paid rather late. At 4 am I got an email asking for a contact phone number. By 9 am Friday I got phone call asking when I wanted delivery. An hour later I got another phone call from the driver apologizing for disturbing me, he was on his way and wanted to confirm my location. On arrival he offloaded the vehicle, showed me every panel and put them in our warehouse. A few hours later the owner of the business Palette Business Solutions Mr. Charles Mezu called me to thank me for my business and trust. And asked if it was okay to come and meet me in person. I was so stunned that I gave him another order bigger than the one I had made.
This morning they delivered the next order and a few hours later he came to visit. Quality people and quality products. Please call them for your LG and Jinko panels. +234 803 373 1860. I normally beg for invoices and I had someone not only deliver but come to thank me
