Pls bell my curiosity. For 2 colleagues installations, curious as to which would be more efficient. A 2kva12v hybrid inverter connected to a 12v200ah lithium battery and a 4.2kva24v hybrid inverter connected to a 24v100ah lithium battery. Both using 2 415watt jasolar panels. Would there be any difference also in the charging time and discharge rate assuming same loads? Thanks

thats maybe an inelegant way of solving a problem, throwing high hp at an issue. recall his major constraint was power- using his inverter to pump water. a 1.5hp sumo would require minimum of 4kw inverter to power it. unless its a dc sumo...then he would require minimum 2kw of panels to have a chance at it working ok.

any sumo has a ''head' as you rightly pointed out, this is written on the spec sheet of any decent submersible pump...and tells you the depth and flowrate of the pump. so a pump with a head of 200ft will work ok, be it 0.2hp or 10hp.....the 2nd consideration now becomes the flowrate, a 10hp might have a 100liter/minute flowrate while a 0.2hp pump might have a 20liter/minute flowrate.............so you then calculate your water tank capacity and usage to arrive at the hp that is optimal for your use case.

the inverter sumo i talked about has a head of 210ft/70meters and flowrate of 35liters/minute...and its being deployed for a single house with 2000liter overhead tank. works ok for that use case. deploying a 1.5hp pump there may deliver water faster, but would be useless as they just have a 1.5kva inverter which cant power it and totally offgrid

1.5hp is the power of the dc pumping machine.
this pumps comes in various design ranging from 48v upto 120v dc (the amperage vary).
a 1.5hp might 48v 10a

earthrealm:


Yes, thats the specs am talking about.
Only thing i dont understand is 600w and 1.5hp tag.
1.5hp is about 1kw...hence the 600w tag is confusing.the flowrate is healthy, though i expected much more.. 1m³/h is about 16liters per minute..that is about 1000liters per hour

Obnoxious2001:


this is the power the pump will consume while working.
using 48v dc as input, you will need 13a to run this pump.....
you can always twerk it to get good result

so technically, his 1.5kva system can run the pump



aside that, who has experience with solar ceiling fan moving the other direction when is about to start
until you push in the right direction before its able to rotate properly

earthrealm:


His 1.5kva system is 12v....no way it can run the pump. @12v..he wud need about 55amps...assuming the pump can even accept 12v.

@ fan, was told its something going bad in the fan.will get worse with time till the fan fails.

Please can anyone give me review on affripower 2.5 kva hybrid , i used it with 3.5kva generator but it does not charge and we hardly have public utility.

try to reduce your charging current. Check ur present charging current

obitobe:


I don't think you can change the charging current, what he needs to do it tune the generator up a bit for it to be able to charge.

Attention to detail is what makes the difference and is a big differentiator when it comes to troubleshooting, both as a hardware and or software engineer. Back in the day, I would boot a client system with Ubuntu (my preferred Linux distro at the time) to access hdds that were corrupted, especially by viruses, then copy the necessary files from my various Windows versions to replace the corrupt files ( i had 3 ex hdds, with 3 partitions each that I had installed windows on for this purpose). To date I don't use any antivirus app on my devices, I use Ubuntu to delete any virus on my system (I had a nasty experience with Avast antivirus). BTW, I love you already. Matter of fact I've sent a dm.

I don't know much about the hybrid, the only thing I know is that it's not a MPPT charge controller but a PWM.
I use the 2.5kva non hybrid and I must say it is very rugged and durable.

I have finally resolved never ever to buy any inverter named by or produced by SOROTEC again! It is truly SORROW TEC(HNOLOGY)! Anytime I think of the inverter I cannot think of a SINGLE good thing about it. it is that subpar! First, the finish is far below the name.
I strongly believe also that the self-consumption is higher than similarly sized inverters. I was not able to measure this though.
The fan is noisy and the inverter failed woefully where Gennex and MUST inverters of similar capacity have thrived. Despite my misgivings, I paid 120k for the useless inverter to be repaired a few months back. I then relocated it for domestic use in my weekend house where I am completely off grid. I tend to visit the place every fortnight ( spending the weekend only) and put a total load of a small fridge, a 22-inch tv and six light bulbs on it. I made sure it was only INVERTING, no other task. Yet, the same error has resurfaced. I am not sure the bloody thing has worked for a total of 30 days before showing its true colours again!!!

By the way, I live alone there before someone will say it was mis-used behind my back!

oga don't mind them, they get what they pay for

Thank you, 2.5kva is mppt while 1.7 and 1kva are pwm

Post-mortem of the plug
@TechGeek777 and Valto thanks

dollarnaira:


If it is from Alaba...e go hard small o.
But definitely not Canadian. Na sticker dem put and e no reach 300w probably 200 or 190w. If the set up is for client DO NOT but na personal use go for it. My opinion.

dollarnaira:


Buy it as used, leave the Canadian parts. There many good panels out there. If it is cheap buy it and use. No matter how, it will serve you in its own capacity especially if your load is small.

Valto:
from the pics this is 200w to 220w solar panel baptised with 300w Canadian solar sticker. don't buy any used panel pasted Canadian solar, jinko, yingli, panda, and the rest, they are all alaba stickers.. close eye buy brand new authentic panel.. u can get real 370w for around 90k

PowMr is a better controller compared with Yohako controller.

That's like saying "PDP is a better PARTY compared with APC party"
