I know it is old thread but I have a masoom sa question why is it written 65 watts on my al sheikh ceiling fans? Are they really that low consumption? I personally doubt that.


#223

it could be average lower consumption, or rated power, or power before PF conversion... or it could be a smaller slower rpm model which consume less by default..

Marketting by companies is a ver shady practice..

Thanks Farhan Bro. That helps me understand something about fans “quoted” consumption. :D

Burning mosfets were the reason I moved form desi to china made Homage. Working ok till now. It is 2 years old.


#226

I am planning a similar setup.

Can someone please confirm if it is correct?

Where can I add switch that switches from wapda to solar and vice versa for charging.

@Forum, That is correct. I am using the exact circuit with a different ups. How much PV watts (panels) are you planning to install and what appliances do you want to run on this?


#228

Can anyone help on this? I am also looking for a similar automatic switch.


#229

I am planning 400-500 watts.

My usage is 2-3 fans. 1-2 laptops , 1 tv occasionally and 2-3 lights. Fans increase to 4-5 at night.

dear whatever the benefit you will get from solar, it is sure your desi ups is gonna screw everything up. but to answer your question, yes the solar charger should keep batteries on a level.

can you share with us the model numbers of the equipment you have then you will get more precise info.

Thanks for your valueable info. how the desi ups screw everything. please explain.

i don't know the model number of panels. model number of charge controller is LandStar LS1524. battery is flooded AGS 200AH

Thanks

There is basically no charging curve for desi ups so it heats up battery and mostly over charges it hence the life time is reduced. while solar chargers usually have 3-step charging curve and good ones have 4-step charging curves including, bulk, absorb, float and equilization. This gives battery more life and keep battery withing safe limites.


#233

the guy who sold the ups, told me that it has 3 step charging kit.


#234

if it is desi i doubt it has. usually they go up a voltage level and then stop charging. normal UPS does not keep battery on float.

Hello everybody,

Hope everybody is fine.

i would like to know, does my setup over charging my battery. here is the setup

200watt solar panel => charge controller => 200AH battery <= 1200va desi ups

now my question is when battery is full ups stops charging it, on the other side does solar panels keeps on chaging my battery. will it ruin the battery or charge controller stops charging when the battery is full.

reply awaited

thanks

If you only have one panel, of 200W only, i highly doubt you would get anything above 3-4amps at peak.. so you have nothing to worry about your battery overcharging...unless you wrote your information wrong.

you should add atleast one more panel to your setup.

your AGS battery should get charged at an average rate of 10-15 amps.. since your panel would be providing a lot less, so chances of your battery being undercharged are a lot more than being over charged..

the charger of UPS is waaayy inferior to the landstar charger, and indeed the charging of the landstar will keep your battery in fit great condition as long as it receives enough power from sun..Landstar are good enough CC for majority small setup/

do you have a switch in between the ups and battery which shifts charging between wapda and solar? and most importantly, what is your load on your ups.?

Thanks farhan.

theres no switch in between the ups and battery which shifts charging between wapda and solar. what type of switch is this? should i install it? is it necessary? benefit of it?

the total load is 10 x 23w energy savers and 2 fans. sometimes i switch on the tv also.


#237

do you only have one panel?


#238

I have 2. Dont kniw whether these are of 100 or 200watts


#239

post pics of your current setup so all of us can understand your current situation..

I'll post 2mmorrow
