Your illustration on the performance of your battery once load is applied is called voltage sag. Those ones with severe voltage sag may not easily return to the previous voltage when the placed load is released, though still depends on the running time of the said load.

Mine is working fine for now be that. The load doesn't stay past 1 hour tops. Na emergency usage things when the grid is down. Thanks

And you equalize monthly?

Merry Christmas house, may the new coming year harbour better climes for RE. Clear sky's, brief heavy non-windy rains to keep the panels bright and clean, less static electricity etc etc
And money enough to meet our needs and sane government in place!
All in all , MERRY CHRISTMAS ONCE AGAIN!!!!

Nothing to add than to say in his case his battery is among the better I have seen.. although depends on state of charge and amount of load.

From all the literature I have read about tubular and from over 5 years of personal experience with an average discharge of just 30%. TUBULAR (which are flooded acid batteries) does need constant top up at least once in 2 months. If yours hasn't been topped with water going into a year then something is wrong somehere and it is not good for the battery.

Not topping up your flooded acid battery like TUBULAR simply means you are charging it at a voltage that is lower than recommended for the battery chemistry. Tubular is designed to be charged at 14.4v per 12v battery or 28.8 for 24v etc (based on all the documentation I have read about them from Indian sources) 14.4 is the absorption voltage and it is best to maintain them at this voltage for at least an hour or 2 to ensure they are properly charged and reduce the risk of sulfation.

They are also expected to be "over charged" at least once a month in a process called equalization. This equalization charge helps to mix up the electrolytes to prevent concentration of acid at the buttom and it also helps to balance all the cells within a battery and bring them to parity. Ordinarily you want this equalization charge to happen at least once a month. Not all inverters support equalization though so you would need to ensure your inverter suports it.

Equalization voltage is about 15.5v per 12v cell or 31v for a 24v bank. Some chargers can do this for you automatically if you ordered program them. You might also want to get an hydrometer to check the gravity of each cell during equalization process.

I would suggest you review how your battery is being charged to ensure it lasts as long as you want it to.

Do you have solar panels with your system, try get more and do such heavy cooking when when the sun is high.

Experienced folks in the house, i have a 1.8kwh agm battery (12v) x 6.

From the information gathered, I need a 5kw hybrid system (i have not made up my mind yet, but considering felicity hybrid, sorotec, growatt for now). the inverter are detailed as 48v. Does it mean that the battery will have to configured to output 48v (?s?p) in other to function.

What are the implications of this configuration and inverter spec on feature solar panel purchase.

I have a 5kw SPF 5000 ES Growatt 6months used and decommissioned already. Working in excellent conditions in case you're interested in Growatt. Thank you.

Hi mango,
Kindly note that you can't connect 6 number of 12V batteries in a 48V configuration.

Depending on your load, either you get a 24V inverter and connect the batteries in 2x3 (2S3P) configuration or you add 2 more batteries to make it a total of 8 batteries and then connect for a 48V system in 2x4 configuration.
Cheers

Yeah I do have solar panels. I only use my air fryer when there's power supply from the grid..the inverter is just standby should in case NEPA strikes as usual

I just dey encounter that term now. I'd have to contact the inverter installer for that one abi?

Mctrinity thanks for the response. If I go 48v inverter, how will this likely influence future solar panel configurations? Does it mean like the battery, I will have to ensure that the panels are also configured to have 48v?

Most inverters I know especially the budget category do not have an ability to auto equalize every X number of days. This does not mean they cannot be adjusted to get to equalization voltage just that a human being has to take care of that process.

Most decent charge controllers have an auto equalize function built in.

Check what your existing equipment is capable of and respond as appropriate - at least now we know one reason why you have never needed to top up your battery water levels.

Would be nice if you could state what brand and spec of inverter you use and what (if any) charge controllers you have

I will still advice get more panels , with a charge controller that can equalize your batteries regularly. There is no excuse for your dryer not to be on your inverter.

The more panels you have the Earlier you can use your drier. My hotplate and deep freezer comes on by 7.30am while the dryer 11am.

Hi! One of the best home appliance products today is GE Appliances. The company is constantly innovating and improving its products, so you can be sure that you are getting the best product.

Topup is in response to low water levels in a battery cell.

If none of your cells are short of water after a careful visual inspection then there is no need to topup.

Beware that any flotation based battery water level indicators are indeed working correctly and not deceiving you hence I said after a careful visual inspection of the water levels per cell.

Once the above checks out and you satisfied yourself that you are charging at a proper voltage for your battery then you are good to go.

That floatation thing sometimes get stuck. Then you are O.Y.O

I haven't been frequent here for quite a while so maybe there are context to this question which are not obvious to me.

On the surface though, it is hard to give an answer without additional information.

What battery capacity, size of solar array and size of freezer in question. State all the details so that you can get an informed answer. There is no universal answer to this question.

I read up battery equalizing and it looks like so much drama with plenty risk for a novice. I use a 5.5kva 24v famicare inverter with built in pwm charge controller and four 350w solar panels

[quote author=samnaija post=119438930][/quote]

I have 4 350w solar panels and if I'm not reading wrong my inverter can only support up to 1200W from the solar panels (maximum pv array power)

I've ordered for one of those auto switch plugs that enable you set when to run your appliances so I can be running my fridge and freezer from 7am to 7pm only.

I have l............
The only mod I would make is that flooded batteries do better at 14.6v per 12v as the minimum for the absorb voltage target. Anything from 14.6v to 14.8v as a regular charge is good. Then the periodic equalization at or above 15v.

@NiyiOmoIyunade

Just want a little clarification. If the manufacturer specifies 14.4V as the absorb voltage for flooded batteries. Is it safe to go the 14.6V as you asserted above? Will it not, on the long run, degrade the battery?

NiyiOmoIyunade:
Dear Boss,

In our private backchannel thread, this same matter has come up for discussion with other users sharing similar experiences
The ones marked pass are the ones I have found to go the distance. The more complex ones with multiple pages of functions including delay and recovery settings and notably a voltage calibration function easily go off kilter and become unreliable.
See pics below - first one is a pass - the others not so

Hmm. Thanks for this. The both looked the same.

If they are not placed side by side, it will be difficult to differentiate between the two.

To add to that, I also noticed the 'Chike' abi na wetin sef written on the other one.

In addendum, dem don change COMPRESSOR before?

So these are usually generic Chinese products coming out of at most 2 or 3 factories. They can put any name on it for you if you are buying sufficient quantity.

What matters is the quality spec or standard the item is made to and the components used.

In general, I have found the versions with several pages of functions to be of low quality.
