Yes I know the max wattage for flex max 80 using 48v system is 4000 watts like u pointed out but from what I gathered from this forum is that a 4500 watts system will most likely not do above 75% - 80% (3600w max) from my pv due to inefficiencies.
So I think I will be doing just fine

I usually don't like commenting quickly on this kind of design posts for a couple of reasons. I usually allow others to do so first while I read. One of the reasons is that I don't usually comment is the fact that the actual applications from my experiences might differ very well from the theoretical designs.

Like Barezzi and c0ogumo has calculated for you, sometimes you will see that if you want to follow the actual dos and don'ts according to the theories you won't install solar.

As a man in the field, the truth is your configuration is perfectly ok for the real life practical application. You'll be shocked that you will hardly run your battery bank (which is theoretically incomplete) down to 50% as long as you have that amount of solar panels installed. This config will run off-grid without any stress. Reason being that you'll learn and adjust your load as time goes on.

Now for the question of if you have to use one cc. Just like I said before that if you want to do all that the solar theory says you won't install solar. The manufacturers of the CCs calculates the number of panels the cc can carry by the rated current carrying capacity and that is why Barezzi said you can load up to 15 panels. But the solar standards say you should leave a head room of about 30 to 40 percent on the cc current capacity meaning if you are using an 80A cc the max load on it should be in the region of 3kw as in your design.

In actual application, I have loaded 18 255W solar panels on an Outback FM80 charge controller (theoretically wrong) on more than one installation site and it works effectively. Why? The reason is simple, it is only very few minutes in very few days of the year that the power output from the panels will hit 100% and above (as in the case of Solarworld Panels) and in such cases the cc will simply clip the excess current and no harm is done to no one. Those moments are very few that they are insignificant. For the remaining larger part of the day/year the output power will remain within the region of 80% (that's about 76A) peak which is safe for your CC operating level.

In summary, you can install up to 18 panels on FM80 should you want to cut cost as you said.

Also remember to use professional accessories for all the stages to achieve a high efficiency.

Do not also forget to buy our Professional Solar Mounts (page 79 of this thread)

Hope this helps someone

Please I need a contact for solar water heater (100 to 200Litres) capacity for a building project. The Protek guy I found had only 300L tank capacities available.

Appreciate any help from the honorable members of the house

My gionee m5 started going off each time I plug in the charger so i took it to an engineer who tried to fix it. Initially he said it's charging point as it stopped charging outrighly. Today he told me d panel is bad and the fone can't work again.please who has experienced this? What is d way forkward? I couldn't locate a gionee centre here in ilorinI bought ds fone last year Feb I don't av money to buy anoda one.

How I recovered my stolen itel phone.....

This write up is to sound a sterling warning to serial phone thieves and people who are accustomed to buying stolen phones.

I bought my Itel 1516 android phone, just 27000, after three month of use, one early Saturday morning i went to popular wine bar shopping plaza at Atekong junction Calabar to catch up with Saturday morning bet. As I was busy handing out my coupon code to bet attendant in that crowded shop that was how my phone disappeared before my eyes.......

I raised alarm, called the attention of the cashiers, and that of the teaming guys hustling to get breakthrough but to no avail.

we immediately called my phone number but no response. One of my friend Mr frank Udama advice me to report to state housing police station which happened to be the nearest police station to book my case incase the phone is used to commit crime afterwards.

I was truly frustrated because of the important document there in, memorable photos, free access to my social media, and my ATM pin, all my passwords are much exposed. i wasn't the type that locks phone.

After two days, that was Monday, the guy who stole my phone have started updating my socials, reply my messages. I quickly visited GLO office at Marian road calabar but the company seems not to have any plans with respect to tracking numbers rather I was advice to go to police which was the option I never liked. I don't like the bottle neck with Nigeria police

One week gone, i was sharing drink with my good friend in a bar, Mr felix Obasi who told me that his neighbor stolen iPhone was recovered. wow!!! he give me his neighbor's contact who also linked me to Mr Bassey Ogah the head of a small unit in the governor s office specialized in tracking stolen phones.

Fast forward, I met Mr Bassy Odey, I paid then sum of 90,000 being the cost of tracking and arresting of the person who stole my 27000 itel phone. I was foolish to my neighbors, friends for spending such amount to track cheap itel phone especially to my good neighbor Mr Roland Odey who was unaway of my reasons considered my action stupid.
However, my reasons for tracking are the following.
*to recover my photos to keep memories
*to protect my passwords
*to recover personal work documents
*to be sure that the phone tracking thing works in naija
* to behold the face of the guy who put me through stress.

furthermore, after somedays Mr Bassey called to show me the exact location of the phone, the sim cards that are in use as well. Immediately his team went out to arrest the dude who was using my phone.

surprisedly, my phone was stolen by one of the cashiers in the betting shop mr William who was close to me, he often call me big uncle. He was arrested and brought to the office with my phone. All information in my phone wiped out, couldn't believe my eyes.

I was advised by Mr Bassy to contact police to arrest him, I resort to peace. My request were to collet my phone which was still in good condition, and to get my 90k from Mr William. His family were contacted, my 90k and phone given to me, case closed in police station.

I was glad that my curiosity paid off. I'm grateful to all who provided me with the information.

Note. before my phone was tracked, I was asked to provide proof of ownership. eg receipt or phone pack.

I have some used batteries for sale @ 30K each.

4 units 12v 200AH AGM and 4 units 12V 220AH Flooded Tall Tubular.

Batteries are sold "as-is". No warranty stated or implied.

Send me PM or email if interested.

JUO has still not yet solve the battery issue and I'm getting very disturbed by the client's call.
If he refuses to get this done this week, I will go diabolical and make sure I ruin him and his business.
He will live in regret and losses for countless years, I can do that very easily... I'm only trying to be good with him so far.
I give him only 7 days ultimatum. I won't make a single post concerning him on here again I promise.

Braaad:
Thanks very much for the encouragement sirs. And a big amen to your prayers @efuro.

I'll do a proper analysis video on it soon. But I can tell you it has all the protections imaginable and standby consumption is very low. This particular one is a 48v low frequency inverter. I use high power mosfets for my designs (some people call it igbt). It runs like a beast. It is very affordable and I give 2yrs warranty on it.

chinexex:
It depends on the factors you are considering.

Higher rate offer, Customer service, Transperency etc.

Make your choices based on these factors.

I settled for ARM after factoring in the above points.
