May God protect our investment as we hand over everything and ask Him to take over from where our knowledge stop.

I love your submission.
This is exactly the strategy I'm using with my 4 x 230ah tubular battery.
I've 100% confidence of making greater use of my battery while hoping to join lithium club in the nearest future.
Then, every controversies about it must have put to rest and the price must have come down.
Happy Easter Solar Enthusiasts.

Does anyone here have Victron bmv 712 smart battery monitor for sale?

Hmmmm. Let me remain in my village for now with my primary education.
I'll visit Lagos, island area/Lekki/banana island when I graduate/return from nysc.

[quote author=Penuelseun

Can't we do this thing without top balancing?
I'm not just comfortable with this balancing of cells.
If there is lithium battery that doesn't require balancing of cells, please let us know.
Until I see a lithium battery someone fixed and stayed for two to three years without balancing anything, I'll continue with my 50% DOD battery.

Please, I need an installer that can install raspberry Pi to my system so I can monitor it online.

50" tv gives out 36w.
This is very good. Is LG or Samsung Products?
If brightness is adjusted, it watts could further be reduced to about 30.
I'm interested in 55".
Can we get it locally at affordable price?
The waiting time is my concern.

It's what I'm using. I've not had any issue since I installed it.

A friend is urgently looking for TriStar Mppt External Meter to buy.

[quote author=blockgeek69 post=110397388]I recently installed a solar inverter system with the following setup:

1. 4 solar panels (each 300watt) = total 1200watt
2. 24v inverter system
3. 2 units of 230amp battery
4. 60amp PWM charge controller

My load at max capacity is 500 watt and could go as low as 300watt during midnight hours.

But I noticed that my battery charge depletes faster than its charging, is it supposed to be so? What i mean is, my battery could be 26v after fully charged with no load, but after 4 hours of use, it falls down to 24.5v even when the solar panel is still charging the system.

So I am beginning to wonder if this is normal or there is a problem with my system configuration or the charge controller itself since i am using a PWM cc.

I guess your batteries are tubular. If it's, then worry less as this issue has been discussed here repeatedly.
Tubular battery experiences sag voltage..

After floating, say 13.3v or thereabouts and the charging source is removed, it will rapidly dro to 12.6v or 12.7v with no load. This is the normal float range for most of the tubular batteries. From here, it will start to drop slowly depending on loads placement.

My advice for you: Try and charge the battery to float stage first. Place loads of about 300 to 400va during the day (when the sun is still smiling). When the sun is off (after removing the charging source), reduce your loads to about 120va or less ( this may be your night loads).
From the time the charging source is removed and light loads are placed, start monitoring your battery voltage drop. If you see 12.1v or 12.0v in the morning, then you're good to go.
Again, focus more attention on load management. Do not overwork your two batteries.... 100 to 120va night loads will keep your battery alive for long.
I used 4 x 230ah and my night loads do not exceed 120va.

ENJOY YOUR INVESTMENT

I bought this freezer three months ago from LG and I thought I was getting reliable product from reputable seller.
If this is truly a non-inverter freezer from the original manufacturer, then I see no reason it shouldn't retain fros. My former conventional freezer retain fros for about two to three days once it blocks.
It's well with Naija!

This my chest Inverter Haier Thermocool freezes faster than the regular non-inverter freezer but doesn't retain fros.

Is this one different from the one you guys are talking about?

[quote author=Namzy

That's great

Namzy:
I use felicity too, and my batteries get fully charged although my setup is 24v with 2 luminous batteries and 340w x 8 solar panels. I'm still waiting for an adapter I bought to fully check if felicity can track daily harvest since its a clone of Pcm60x and has a RS232 port hidden inside the unit (not mentioned in the manual)

You mean you're using 340w x 8 panels (2720w) to charge 2 luminous batteries?
I'm trying to imagine the type loads you use during the day that will be limiting the charging power of your batteries. Excess power/overcharge of the batteries is my concern here.
Please, let me know your logic.

[quote author=Bolatitodavies

Please, worry less about the charging status of your system and see how you can readjust your home appliances power consumption. I used a similar setup and wake up in the morning with 70% power left with my batteries. I made sure my night consumption, idle power consumption inclusive, do not exceed 200va. In this case, topping 30% even with bad weather and other opportunity loads will be very easy.
Once you wake up in the morning to see 50% in your batteries, you'll be struggling to refill it (especially with bad weather and those that do not oversize their pv).
Just as others had pointed out, try and clean up the panels, get timer or manually switch off the heavy loads appliances once the sunset. Oversize your pv if you've the cash but if you do not have the cash, management of loads can still give you daily battery float even with bad weather. Again, look for multimeter and measure the actual voltage of those batteries and focus more attention to management of loads in the house.

How do you guys deal with Amazon?
I wanted to place order for TriStar Mppt External Meter and the company refused to tell me the expected delivery date.
I'm very sceptical about the whole thing.

[quote author=samnaija.

No matter how bad the weather is, my battery usually get to absorption stage every day but getting to float is difficult this day.
I was thinking not floating the battery at least every two days might affect the life of battery.
Thanks for your advice sir

QUESTION.
If I float my battery today and I wake up the following morning to see 60% left,
charge it again and the battery get to absorption by 3am or refuse to float due to dull weather. I now use it again and wake up the following morning to see 60% left, what effect will this have to the life of the battery?

In this case, the flooded battery hasn't been fully charged for about two to three days but 50% DOD hasn't been exceeded.

I mean 14.4v each and 14.3v each. That's 14.4v, 14.4v, 14.3v and 14.3v from the digital meter.

[quote author=mctfopt

The batteries are in absorption now. I've taken the measurement three times now with digital Meter, two batteries read 14.4v and the other two read 14.3v

Voltmeter reading now are 14.4v, 14.3v, 13.9v and 14.3v.

The digital meter reading and that of voltmeter should be the same, but they are not.

I'll charge the battery individually and check it again tomorrow.
Thanks

This is the system.
Please, I really need your help

PLEASE HELP!
3.5kva 48v Felicity Inverter, 60A TriStar Mppt and 4pcs of 230Ah Genus tubular batteries with balancer installed.
Since the batteries has been on ground for months, I knew the batteries will be suffering from sulphation. So i decided to set 15.7v for equalisation and 15.1v, 14.9v, 14.5v and 14.7v were shown on Voltmeter.
After 3hrs, the readings returned to 14.4v, 14.1v, 13.8v and 14.1v.
This readings maintained till 5pm due to dull weather.
I went out by 5pm and returned by 6pm to see the readings 12.3v, 12.4v, 11.9v and 12.3v.
I've Not placed any load on the system since morning.
Though I don't know the idle power consumption of this inverter but I'm worried about the sudden drop in voltage.
Is it because the battery wasn't floating?

Could battery deviation has a role in voltage sudden dropping?

Since I've equalised it today, do I still need to equalise it again tomorrow?
