George_D: teamman,

how many hours on daily average do you run each of these equipment?

George_D: teamman,
so skipping your houseload (since we have little information on that), we go straight to your
battery bank size.

you have two battery banks of 500 amphours each at a system voltage of 24v. but you're only allowed to
discharge this up to eighty percent of capacity (80 percent dod for deep cycle). so this becomes 400
amphours available (useful) capacity.

400 amphours at a system voltage of 24v becomes 9600 watt-hours.

given a solar insolation of 5 hrs (which is usually the average for our geographical location), you
will need a total of 1920 watts solar panels.

but, solar modules are not 100 percent efficient, so factor in module efficiency, and this becomes

2688 watts.

therefore you will need about 2700 watts of solar modules to effectively charge each of your battery
banks.

also, consider installing two separate charge controllers, one for each battery bank as it is not
acceptable practice to use one charge controller to charge two separate battery banks.

hope this helps?

earthrealm: if i get u right..u are using 2v 500amphr batteries?..if yes..then it implies that u have 12 pieces of the 2v battery connected in series?. doing the maths 24 x 500 = 12000w factoring in losses/effieciency factor of 0.8 .implies that ur total available wattage is 9600watthr. so divide this 9600/[ur load in watts] = inverter run time in hrs, lemme assume u hv a total of 600watss load..then ur inverter will work only for 16hrs b4 it needs recharge.

on the issue of solar panels assuming u hv 10hrs sunlight per day thus ur total capacity/10 = 960w, so ur combined solar panel need is 960w, adding efficiency factor of 0.8 implies that u need 1200watts of solar panel...so the minimum nos of panels u need is 200w x 6 units solar panel, or 250w x 5 units solar panel etc....
note: this is the minimum nos of panels you need...its always advisable to have more than the minimum.

other members pls feel free 2 correct me if am wrong

radeniran: Auto Guru in the house i need your help to sort out the overheating problem i have with my car (HONDA ACCORD 97 MODEL L4)i have done a lot of changes to the cooling system of the car (Changing of radiator, changing of hose, adding of coolant flushing of the radiator) all to avail.
I noticed the problem after i did my routine servicing of the car and my auto technician changed the lubricant i do use for the car though the lubricant is from the same manufacturer but of different grade.

Water now leak from the Injector that is what i noticed this morning i cant drive 2km without the thermometer not reaching the climax.

What is the way out of this problem

mutter:
Go there personally and thank her for standing by you all these years. all the above are super ideas.
You need to say the words yourself and possibly public.
That would touch her.
Thanks
