For 5kva 48v with 18w/12v solar panels,u will use 8 of it each cost 50k and a 48v charge controller(25k), plus inverter...everything sums up 2 700k

jaz:


thanks bro. that's within budget

oblo:
A friend has used 6kva inverter for immediate sale. Working condition and very good for those of you who don't want to break the bank to get a 6kva inverter.

Location is abeokuta.

Hi,
Your replies and inputs are highly informative.
I have a 5KVA and a 3.5KVA inverter used to power different sections of my house. Each is having 8 numbers and 4 numbers 200Ahr batteries respectively. What is the minimum rating of a generator set that I need to charge these inverters separately and also together?

ify7:
hi can you share details. I have an issue with my "2000W must power inverter" and have not been able to get support. i don't mind in home service (if possible) as the inverter is wired to the house

My final question. I have a load of 1.5 kW that I would want to power for 10 to 11 hrs. I have a 3.5kVa inverter (48V) and 4 12V 200AH deep cycle batteries connected in series. How long would it last?
PS Talking through how the answer is arrived at would be very helpful. I might want to play around.

Hello roomies,......I need an inverter that could power my hp laptop (14 inches) + a standing fan + 1 energy bulb!.....I'm thinking about purchasing a portable generator but also concerned with the costs of fuel!.....I'm a student, and I could charge the inverter with my school gen!.....needs reply

Please i want to know if it is possible to use the LG gen cool inverter V air conditional on gen mode of 0.9kva on my Prag 2.5kva inverter with 4 prag 200mah batteries? I expect your response house.. Thanks

Deluxe8000:
i have 20ah battery charger to charge my 200ah battery but it seems it discharges when main phcn source is off cos its meter reads even when phcn source is off. pls wat can i do to stop it from discharging?

femiolorun:


as a student i guess you generator will be i pass my neighbor, if that is what you have and there is no regular PHCN, charging will be difficult for you most especially when its down. at times it takes 12 hours to charge a battery to full. think twice

femiolorun:


pls clarify the above character

folamingo:


ok, I have a 2.5kva prag inverter with 4 200A batteries. I recently heard about an LG 1HP AC that can work at 0.9kva using a generator mode feature on it. In order words reducing the start up power consumption that normal traditional AC exhibit.

My question is does the generator of 2.5kva and the inverter of 2.5kva operate in the same manner, and would it be safe to connect the LG 1HP AC that has the feature of Generator mode to the inverter?

Thanks

It's been quite a while but the thread keeps getting better

With a load of 1.5kW your draw at the dc side is 31.25A, if you continue with this load for one hour, you'd have drawn 31.25Ah out of your 200Ah bank. Neglecting losses due to battery discharges and cabling and assuming you want to maintain a DoD of 50%, in order to lengthen your battery life, then you can only run this load successfully for 3hrs or 5hrs (worse case scenario & jettisoning DoD) before your inverter shuts down.
To achieve your goals you would need at least another parallel string of 200Ah 48V to bring your storage Ah to 400Ah minimum.
Alternatively you may work on your load, take lighting and some other load to dc with very low consumption, so that your overall consumption is considerably reduced.
Remember power at the dc side of your inverter=power at the ac side (theoretically speaking and assuming minimal losses) consequently current draw is a ratio of rated power to voltage. hope this helps

My 3 5kva luminous inverter backed by 4 batteries usually powers my fridge, tv and fans dor two days when fully charged. Now it doesn't power all these items for 24hrs except the fridge is off. What could cause this.

I have had the inverter for 8months.

Ultimate AGM
Hoppecke (I hope I got d spelling right) -dis is a German product and its badass
Hipower Lithium -this is another very good battery.
Haze Solar
Lifeline
Trojan
Synergy

Pls note batteries on this list last btw 5-10yrs depending on its use. 100Ah Hoppecke 4 instance equals 2-3 chinese equivalents
