24v system
I'm willing to get bi-facial jinko panels and also hybrid inverter. I can still do like 700k
I need a setup that will charge my battery well and also supply light during the day well without consuming much of my battery. Only things connected to my setup are light bulbs, 3 ceiling fans and 2 standing fans, 2 TV, one game console

Good day my fellow comrades. I joined the solar energy generation path due to NEPA aka PHED showing me too much shege, especially sleeping in darkness for several nights due power outage. I don't have much knowledge about solar energy. I was just asking grok for most info and suggestions about my intended setup before now.
- I have 4 pcs of jinko 535w bifacial connected in series
- I have Jsdsolar pure sine wave 4kva - 3.6kva continuous rating transformerless inverter (hybrid)
- 1 pcs of Itel 24v lithium batteries
- We couldn't install the thunder surge protection device as my apartment has no earthing rod.

My installer installed the solar panel on the roof and did the wiring and tried activating the inverter and battery but couldn't. He got exhausted and left promising to come back later.

I however read through the inverter Manual and configured the inverter settings which was about 44 different settings in total. The system came on and was running on steroids during charging and testing on home loads.

I later disconnected the mains supply line to the inverter as I observed that it like charging the battery rapidly through the mains as I don't want my NEPA unit to be spent charging lithium battery. Also the Inverter self consumption with no load on NEPA or solar panel is ranging from about 70w to 100+ as monitored Via inverter and calculated using measurements from digital multimeter meter.

The inverter is actually very smart and will cut it power off if it detect abnormal condition, wrong connection, surges etc... Sha I de try de careful I know wan roast the machine...

My concern in this my setup is that
- I couldn't set the BMS protocol settings, all attempts to romance and try different protocols was abortive, I had to latter switch off battery monitoring via BMS protocol with ethernet cable unplugged for peace to reign.

- I am unable to know how much I am harvesting from the sun via logged meter interface and to see the performance history of the system over time.

- How do I reduce my inverter high self consumption when solar panel input or mains input is active.

My battery float settings was initially 27.6v and I later brought it down to 27.4 volt though AI recommended 27.2V. My battery cut off is 23.9v.

My house load is
- 4pcs of 15w bulbs
- 4 pcs of 5w bulbs
- 1200w akai microwave
- 43 inch Samsung tv
- 1000w Phillips dry pressing iron
Samsung small fridge running load is about (100 - 120)w
Pumping of water from borehole once in a day for 30mins (pump capacity monitored from inverter is 1.1kw with a rewinded coil.

I need input from this community on how I can maximise the use of the system, my goal is to run on full battery mode for at least 2 days without NEPA or adequate sunshine. I want also to be able to monitor the system performance down to if possible battery BMS behaviour in real time or near real time..

Pls inputs and advise from Everyone is welcomed.

CuteMaro:
If you're able to set up float from inverter you should also be able to set up charging current from the inverter interface. Kindly pick up your manual to see how to set up grid charging current and adjust to your taste. What is the capacity of your battery?

eddycurrent:
Battery capacity is 24v 100AH

Grid was preset to 50A, I refuced it to 20A then later 10A. I later disconnect the grid supply due to prior mentioned high standby consumption and inverter fan running continuously when grid or panel power is active.

The charging max input current from all sources during charging is set to 40A Vs 100+ Amps that the inverter can support

Drgreatone:
Solar alone wont be enough to adequately charge ur batery cos of its chemistry. Reason u didnt notice like u said was because u had NEPA. Tubular batteries take longer to charge so the daily 3-4hrs of peak sun might not suffice.
MPPT would have to be a high voltage one which is rare and expensive compared to just getting an hybrid. The common blue powmr needs a max VOC of 105v for 24v battery which u may overshoot with ur 4 panels as one doesn't know their VOC

CuteMaro:
I have a 1.5kw 24v Welion hyrbid inverter unboxed going for cheap. I think it's suitable for your load in this condition and you won't have to buy an external charge controller. Indicate if you're interested.

Betnomore:
If I'm to upgrade my inverter, I can't do 1.5kva anymore due to the panels I'm buying. Si it has to be from 4kva upwards

CuteMaro:
The pv input for this inverter is about 1.2kw so yes your 4 pieces 300w panels can still go with it but I doubt if it will be very efficient in charging your system especially on cloudy days. My understanding is that you're on a very tight budget.

Betnomore:
Only if I can just remember that moniker that drew socket for me for paper and posted the picture here when my luminous inverter socket was always burning. Na that guy go fit explain to me well well

favouredbymercy:
I don give you headway sinceeeee.

Contact Dam5reey for Haisic 24v Inverter, and get 4 Jinko panels. Use your Tubular for now till you are able to upgrade.

Cheers

Betnomore:
Will this scenario work perfectly for my setup.
1. Getting four 590w jinko bi-facial panel
2. Getting a 4.2kva hybrid inverter (powmr or any other affordable and good brand)
3. Still using my tubular batteries
If I do all the above, will I enjoy light very well during the day and will my batteries charge well enough to cover me throughout the night.

dollarnaira:
Why u no wait for response before you climb up? Pele

Haykay2001:
That should be dollarnaira I believe

Betnomore:
I specifically asked you to please contact me on Whatsapp so I can ask some more questions. I guess you either didn't see that or you're not comfortable contacting me. Either way I appreciate your input. Which size of 24v haisic inverter do you recommend for 4 590w jinko panels. Also am I over panelling with the four 590w and is the haisic better than powmr. Thanks for your input.

Betnomore:
Na him oooo. Thanks a lot

Haykay2001:
What ever you choose, Do inverter way get service center boss..I know haisic get, but don't know if powmr get sah

Haykay2001:
His number they hin bio..

At end of the day, anyOne who's getting started in Solar journey and spending from 2 million naira and above ought to start on good footing ELSE sooner or later, they realize their mistake(s) and would want to make amends ONLY at such stage, they would incur losses.

Might have misCalculated last night due to my mental state (there's only how far one could cheat nature) BUT that doesn't change the fact you're better off with a battery of 48v 200ah THAN 24v @ 400ah especially since the switch from 12v to 24v; or from 24v to 48v ain't about changing the battery alone.

When you get the foundation started this way, chances of having to sell off things to UPGRADE later on would be less.

One could always add more or replace the battery in other to get (much) bigger capacity BUT if you have to upGrade, you must change some other things which ain't cheap.

They might tell you for such a small system, 12v or 24v system is OKAY but what no one seem to be saying is - is the MONEY also small ?
if 12v or 24v system is SMALL but the cost of acquisition is +2 million naira, then it's NOT small to most of us. Yea I know ₦2,000,000 is like ₦200 to some people BUT that population is a lot LESS than most.

Another thing is, most times we tend to overSize our battery bank unnecessarily which though seem good BUT could lead to diminishing returns when done without adequate knowledge. yea having a batteryBank of 800Ah would give more peace of mind than 400Ah in certain situations BUT a lot of times, we do it the wrong way WHILE at other times, we need first invest those funds elsewhere to help make the system more efficient.

I currently got extra 3 pcs of RiTAR 150AH battery which are not in use BUT for sake of preserving the batteries so they don't go bad, had to pair them with another hence now having 4pcs of 150Ah batteries in series giving 12v 600Ah BUT guess what, I only had to do that because leaving those batteries lying around would affect the batteries, not that I needed 300Ah let alone 600AH.

Most of the power we need happen during the day and at Night, except those who use heavy appliances at night e.g AC , electric cooking stove, water heater, etc; we really don't need much at Night.

Even to run heavy appliances more efficiently, you 're better off with 48v than with 24v. i personally run both 12v system and 48v system. The 12v system I run is because of specialized purpose and reasons.

Marketers and those who wanna collect your moneies would tell you how Tubular or Lithium batteries could last for so so so number of years BUT they fail to give you the other variables involved.

Like I often say in here, there's ever 1 looser and it's hardly the installer or the marketer or the seller or the whatEver; it's always the one doing the spending which is the customer most times.

Most times, anyOne starting on clean slate with 24v system could almost always afford a 48v system.

My 12v system is currently 600Ah but I don't need more than 200Ah for almost the entire day (assuming weather is so poor) because the bulk of the task are done during the day time and at night, when the battery is about 95% filled, rarely do I need up to 100amps the entire night. And mind you, I still have 12v system because of specialized needs + I don't even use an inverter for the 12v system, just solar panels + chargeController + batteries + load.

See eh, you buying things and later selling them off in other to do what you ought to have done initially is actually a Good thing for the Frugal ones among us because it means the number of USEd items in market is high enough to keep prices down.

the advantage of being in midst of people who have fallen and made mistakes in the past (ELDERs) is so you learn from them in other not to repeat such mistakes BUT either way, you learn the normal or hard way; na your choice

Betnomore:
It's not there. I've decided to go with the haisic but the person they referred me to I don't like his response when it came to to us agreeing on how to go about the sale. Or maybe na just clash of egos shaa. I don't want to go into details but if I can get someone else here to buy it from, no problem

Ahhhh.. His a very very very very good guy ooo.. I done buy same haisic from him although 12v also 15kwh battery his a very nice guy oo seriously..

Seunmuham:
please I need input. My sister is trying to set up a phone charging business. Her budget is 700k and she needs a lithium batteries for peace of mind. Abeg how do we go about achieving this

Haykay2001:
Make she manage am reach 1.2 or 1.1M ... So that she go fir run am 24v and upgrade small small later.. That 700k will only get her 12v system..
