As I was reading your post I remembered something the Ariston water heater rep kept emphasizing - pressure!!! - he kept trying to get us to buy the more expensive pressurised water tank instead of non- pressurised insisting that the non-pressurised could not withstand anything above its rated limit at all and would soon start leaking at the seals.

Did you eliminate pressure above the Protek's rated capacity as a root cause of the leaks?

I am glad that at least you found a work around to deal with the leaks.

GeorgeD1:
all,

after getting banned severally for the past couple of days i have finally decided
to go the attachment route. let's see if the botman can read attached files too

so, finally there you have it.

niyi,
that's one of the things they claimed happened. at a point after installation
i decided to remove the assistant tank and connected the cold water inlet
directly to the tank. i did that because i noticed it always took like forever
to fill up whenever i drain the tank for whatever reason. but after the leaks
started and i called them to complain, they advised that I should put back
the assistant tank saying that the main water tank pressure was likely one
cause of the leakage. well, I re-installed the assistant tank and noticed a
slight improvement but that was it - the leakage was still there.

My "hack" still works though it's got an ever so annoying and irritatingly persistent problem.

Good to know you are seeing some improvement now - is it possible you have some shading/shadow on your panels in the evenings from around 4pm? e.g tree line, tree branches or tall building, fence, water tower/tank casting shadows on your panels?

Please check and revert

Thanks for the input Oga Niyi.
there are no shadow casting of them at the time I checked.
I had to reset the pv input breakers and the voltage returned to 36volts
I guess some thing has smoked in this Epever, I think I would get a pwm while I get somebody to take a look at it for me

A regular 1.5 HP air conditioning unit will consume about 1500 Watts
So it would be 5 x 1500 Watts = 7500 Watts.

You might want to leave some headroom for other loads; so you should be looking at nothing less than a
10,000 Watts inverter i.e. 12.5KVA or more. A real inverter not some chinese disguise

Even with this, you cannot turn on all units at the same time due to surge current. You'll probably have to set them on a timer
to turn on, say between 10 - 30 seconds, after one another.

1.5hp is actually about 1125W(i.e 1hp is about 750W). So 5 x 1125W = 5625W (let's say 6kW rounding it up).
So a premium 8KVA inverter (to compensate for inefficiencies) with at least 30% 5seconds surge headroom is adequate. And yes, avoid turning all units on at the same time as rightly noted by makavele.

nope sir, you are wrong, makavele is right, the 1.5hp written on a 1.5hp ac is actually just the rating of the compressor at 100% efficiency, the energy consumed by the internal components arent stated, such as the blower fans, and inefficiency of the ac etc, so its safer to assume 1500w,, my 2hp ac has 2800w as max energy consumption and 1800 as avg abi min consumption, so looking at that you can see its way over the 2hp energy nameplate.

@op, get a good inverter with a good surge rating, 5kva mustpower has a surge rating of 12kw, as a 1.5hp ac has a surge load 3 to 8secs duration in excess of 4500w when starting

I earlier today acquired one of these MUSt units, as advertised. Many thanks, kiekie1, for the sale and very prompt delivery service.

Dear forumites, let me in a way come out of my small DIY closet, lol... this acquired unit is part of my ongoing ensemble that includes an MPP Solar PCM60X CC, 1.320KW of panels (soon to be upped to approximately 3KW) and 800AH of AGM storage (not yet in place, but planned to be 400AH @ 24V.)

In all of this, I must mention here that NiyiOmoIyunade, davodyguy, as well as others have kindly provided me with most of the education, technical support and encouragement I've needed in the background. And for that, as well as the amazing posts on here that I've seen, I'm very grateful, guys!

I look forward to reporting back on here, as this project gets off the ground, and possibly goes into production and harvesting.

You and Makavele are right... Only the compressor is quoted. I bought 1hp thinking its 750w only to power and it's consuming 1125w....i was like wtf!

Op should get a Mikano generator as that kind of load is not economical with inverter

Yes yes, you are right. I didn't account for those other components. That's why the saying "Two good heads are better than one" is very true (as long as they are not on thr same shoulder ).

Please what is the Inverter capacity that can power 5 (1.5hp Air Condition) at the same time. Thanks

Waoh......... Thats a heavy load. I'll advice a 15Kva(>=180v DC), and at least 2 strings of battery bank. And just like as earlier advised..... All a.c's cannot start at the same time, there's gotta be some 1-2 minutes delay in between.

Am loyal Sir .. Remain blessed !

If you are on a budget then do the ZHC battery equalizer which has been reviewed several times on this forum - one single unit will do four batteries or even 8 or more sef if you know what you are doing. Costs ~$60 for one unit.

https://www.amazon.com/dp/B01JJ4X8CO/ref=cm_sw_r_sms_apa_i_BJhbBbYN5XEM5

Premium is the Victron battery balancer - you will need 3 units of these for a 48v system - each costs about $72

https://www.amazon.com/dp/B01DH6B2D2/ref=cm_sw_r_sms_apa_i_EGhbBb7SJQHKM

There is also a Fangpusun unit which is an exact Victron clone - JUO sells these on this forum - everything I said for the Victron applies except that it's cheaper and made in China.

We will keep trying to improve in customer service .. I won't advice you use balancers on set of old batteries or different brands/ahms of batteries. Its best applied on new set of batteries . Charge batteries one after the other before hooking them up with a balancer of your choice ! Cheer's

Thanks for the swift delivery

I am not aware of any reason why one cannot use a battery balancer on old batteries. It is common for one battery in a series connected bank to age and weaken and drift apart from other batteries in the bank over time and this is the very problem a battery balancer is designed to solve by shifting power from the stronger battery to the weaker battery.

With new batteries, one may not get all from the same production batch and if you do, each battery would still have differences in its internal chemistry and behaviour hence balancing would be required in most deep cycle usage scenarios. Lithium seems to have caught up to this reality faster than Lead Acid because nearly all good BMS have some sort of battery balancer mechanism built in.

People have even used balancers to successfully combine different ages or types of batteries with good success - this is however not an excuse not to follow the standard battery setup and usage best practices i.e. using only closely matched batteries of similar ages to make up a battery bank

Good morning , you quoted my advice about the use of battery balancers on old or already sulphated set of batteries but I had strong reasons for saying that as battery balancers don't do MAGIC on dead or sulphated cells. I hope you remember we are dealing with lead acid batteries and not lithium batteries which can be discharged below 50% dod under higher number of cycles We have clear youtube videos stating how the battery balancer works having in mind that it works on general12v battery set up and not individual 2v cells which might have been sulphated due to constant abuse before the application of a balancer ..

NOTE:
-Sulphated battery is sulphated
-A battery with lot of internal resistance or bad cell won't always give you good results.
-A battery that has been under / over charged on regular basis and showing signs of weakness due to excessive heating, premature shedding of plate oxidation material, loss of electrolyte etc might not show the efficacies of battery balancers ..

You have done a lot of experiment I believe with BLS desulfators etc and see it dosnt do fast magic before you decided to apply the zhc balancer on your new set of 48v 38400wh lead acid batteries at an early stage which is best ..

Summary of my initial post was to start from an early stage if you must use a battery balancer

I reserve space for more opinion from forumites who has used the battery balancer on old systems already showing serious signs of reduced back up time . Cheer's

Oga KieKie - we all know that battery balancers do not perform magic on batteries - they simply shift power from stronger to weaker battery and by this method they would buy you a few extra hour(s) of backup in a scenario where you had one or two weak batteries in a larger set of four.

You have expanded your post now to cover dead cells, sulphated batteries, loss of positive plate active material and other matters which you didn't mention in your original post. All in all a mish-mash of matters which I don't even understand their relevance to the OP's original question except perhaps you have an insider's perspective since you may have sold/sell batteries and other equipment to him

Going back to the original question, I have used balancers in battery banks where one battery was going weak and drifting relative to the other batteries in the bank and recorded significant success - people can get a balancer to get maximum mileage from their existing battery bank and simply migrate the balancer to their new batteries whenever they are ready for a change/upgrade.

To be clear you must apply the right treatment to the right problem so a battery balancer such as the ZHC was never designed to fix battery sulphation or dead cells e.t c so if that was the stated problem, then other interventions up to and including battery replacement are indicated.

Good morning , you quoted my advice about the use of battery balancers on old or already sulphated set of batteries but I had strong reasons for saying that as battery balancers don't do MAGIC on dead or sulphated cells. I hope you remember we are dealing with lead acid batteries and not lithium batteries which can be discharged below 50% dod under higher number of cycles We have clear youtube videos stating how the battery balancer works having in mind that it works on general12v battery set up and not individual 2v cells which might have been sulphated due to constant abuse before the application of a balancer ..

NOTE:
-Sulphated battery is sulphated
-A battery with lot of internal resistance or bad cell won't always give you good results.
-A battery that has been under / over charged on regular basis and showing signs of weakness due to excessive heating, premature shedding of plate oxidation material, loss of electrolyte etc might not show the efficacies of battery balancers ..

You have done a lot of experiment I believe with BLS desulfators etc and see it dosnt do fast magic before you decided to apply the zhc balancer on your new set of 48v 38400wh lead acid batteries at an early stage which is best ..

Summary of my initial post was to start from an early stage if you must use a battery balancer

I reserve space for more opinion from forumites who has used the battery balancer on old systems already showing serious signs of reduced back up time . Cheer's
