In trying to understand what 50% DoD for a 24v norminal system in Volts... Eg, from 29v to 20v, 21v,22v,23v or 24v use? considering that at rest, a Lead Acid battery would always drop to 26.xV without trickle charge (Float),

I got this unsatisfactory info:

what is 50% DoD for a 24v norminal system in Volts... Eg, from 29v to 20v, 21v, 22v, 23v or 24v use? considering that an rest, a Lead Acid battery would always drop to 26.xV without trickle charge (Float)

ChatGPT
If the nominal voltage of a 24V system is assumed to be 24V, then a 50% depth of discharge (DoD) would mean that the battery has discharged half of its capacity, which would equate to approximately 12V.

However, it's important to note that the voltage range you provided (from 29V to 20V) is a bit wider than what would typically be expected for a 24V battery system. Additionally, the resting voltage you mentioned (26.xV) would likely only be applicable after the battery has been fully charged and then allowed to rest for some time without any load or charging.

In general, the voltage of a lead-acid battery will vary depending on a variety of factors such as temperature, charge level, and load, so it's difficult to give a specific voltage range for a 50% DoD without additional information about the specific battery being used and the conditions under which it is being operated.

Can we have more indept info better than the above please from any member in the house...

The scenerio above is considering an off grid instance where at 5pm, the sun is completely out and loads depend on the backup till next morning

With the small knowledge I have, once your batteries hit 24V, that's 50% DOD.

Without load and solar/PHCN, my fully charged batteries sit at around 25.1V to 25.3V.

Guys abeg, I need your help and clear advise - preferably from those in the know.

I urgently need to set up 10Kva solar system and I need your advice abeg.

My needs are simple: power 2 inverter AC at least for 24 hours. Lights and TV, occasional water pump use.

I have narrowed things down to using LiFePo4 batteries due to have a longer use life, but picking a reputable brand seem to be a minefield. I'm leaning towards Felicity but I am not even sure anymore due to all I have read about them etc. Please advice.

You can get an 8kw hybrid inverter or simply get 2 unit of 5kva 100a inverter that is parallel compatible and parallel them to get 10kva 200a mppt.

You can contact me for your hybrid inverters.

Sonoff still available for sale 8500 per unit

Still available

If you have a 24v hybrid with low VOC mppt for sale do quote me with price

There are always choice to make when it comes to setup like this

for inverter there is a choice to go for all in one system AKA Hybrid DEYE, GROWATT, AXPERT, SRNE or a normal separate inverter VICTRON, ANY OTHER INVERTER with torodial transformers and match it up with other necessary accessories

your estimated energy is in the range of 53KWh and above with matching panels that can pump that battery up daily in good sunlight.

A recent project delivered all the way south Nigeria.

Pls can i add a 12v 100ah or 12v 200ah lithium battery to my already installed 12v 220ah flooded luminous battery?

not advisable as their charge profile is different

Oga o!!!

Neat job.

I have a 3pcs 306watts solar panel
I have a 12pcs solar batteries of 12V 100Ah
A 2.5KVA inverter
A Charger Controller of 20A.
Please what can this batteries carry and how long can it be used.

Wat kind of panels, are they new?
Wat kind of battery, are they new?
Wat kind of inverter
Ur charge controller amps is too small, b it pwm or mppt, so u don't av a charge controller.

Good evening all. What are your opinions on these types of inverters?

Bad for:
Smart tv
Fluorescent bulbs
Freezer/fridge
Fans

Do you mean I shouldn't use them on these devices you mentioned? Because I use them for my 10watt bulbs, charger, rechargeable fan, and TV. Is it safe?

Hello guys. What's your thoughts on the use of voltage equalisers on batteries connected in series?

I am considering buying one to use with my setup.

I strongly believe you've already done your energy consumption calculation to arrive at 10kva inverter. I'm sure your plan has exceeded two units of 1hp otherwise 5kva inverter would've taken care of it but for the sake of people like us who may have an intention of powering our ACs with solar too, I'll like to know the two AC horse power you intend to power with 10kva inverter sir.

Oga thanks for the reply.

This area isn't my strong point but the 10kva calculation is to cover for additional needs. E.g Supplemental flood lights (I find that solar powered one lacks the intensity of brightness as Electrical powered ones of same wattage)

There are then the occasional use of washing machine, water pumps, iron and other miscellaneous. I am open to your views if you feel a smaller Kva is better.

Just a quick recap, 6 ACs in the house but only 2 will be in use at most point in time. The ACs are all 1kva inverter types. Fridge/freezer will be on 24/7, flood lights (400watts or so x 6 points will be on from evening)

I look forward to your analysis.

Thank you. I added a few of those names to my list and I have been actively looking and reading around small small.

You estimated 53Kwh, abeg how much is that in Kva?

Well, energy independent is all about personally satisfaction. If you have the fund and you're not on budget go for it but if you're on budget, go for 5kva inverter and 15kwh lifepo4 battery with sufficient pv and reduce the running time of the AC especially at night.
Someone posted here few months back that 1hp inverter AC consume about 487w. Running two at the same time will consume 974w, freezer might be 150w, fridge might be 110w, iron might be 1200w... Total 2,434w. Sufficient pv will take care of this during the day and charge your battery to float. You may also choose to alternative other appliances like pumping machine and washing machine.
Switch off the freezer in the evening when the sun is off and by this time, things has already blocked inside. You may allow the two ACs to run on battery for 9hours at night (8,766wh).
I'll advise you go for standalone floodlights and do not attach them to your system. I've 8 standalone floodlights in my compound running for two years now. They are all in sensor mode, turned on at night by itself and turned off when day break.
If you still need a bigger system, 8kw deye inverter might be a good option with 28kwh lifepo4 battery and corresponding pv.
Our big boys will advise better.

I need 1hp and 2hp inverter AC. Olopan said 1hp inverter AC is 480w while 2hp is 2100w. Please, what is the name of these products?
Does anyone here have better options? I'm more interested in energy efficient products as I intend to run them on solar.
