Where can i buy epsolar charger cantoller Mppt model Tracer-4210RN 40amp

Hi

where i can buy epsolar Mppt model Tracer-4210RN 40amp...in pakistan also what is the price this model..i want to buy orignal epsolar..

thx

Rs 25K buy Tracer 4215RN not 4210RN. both nizam solar and beon solar had it.

yousif thx ur support..its true MPPT cantler increase energy 30%?

can u tell me why i buy TRACER-4215RN MPPT?

marry pass 3panel 100wat k hai aur 2 panel 150waat k hai..kiya yah cantroler work acha karyga es system p?

i will add more 300wat in my system in 2month

Yes, MPPT tries to keep the Voltage and current of the solar at the maximum power point at that particular time. different mppt charge control work at different speed or in other word they sweep at different rates.

4215RN support VOC upto 150 while 4210 support only 100V

you haven't posted the electrical specs for your 100W panels.

If you can find Tracer4215BN http://www.epsolarpv.com/en/index.php/Product/pro_content/id/573/am_id/136 it is even better.

4215Rn and 4215BN can support a maximum of 520W on 12V (single battery) or 1040W on 24V( 2 battery) systems.

a even better controller is Midnite Kid http://www.wholesalesolar.com/products.folder/controller-folder/MidniteKid.html

It is 30A only but does support 48V systems and have quite good support. It can be overpaneled but the current will max out at 30A.

Two Midnite Kid can also be paralleled for total of 60A.

Explanation 1

Cost saving in wiring

[quote="yousaf465, post:6, topic:21295"]

Yes, many people have imported their own Panels and related equipment. For upfront cost you can start with Large MPPT controller and a 1-2 panels. You can add more panels later on whenever your budget permits.

Thick cables are only required if you are using PWM type of charge controller with a large array, which in my view is just waste resources, both your money and solar output.

Array larger than 400W must use a MPPT charge controller. What it does, it allow you wire your panel in series for voltage upto 150V( normal MPPT charge controller) or 250V-600V(only 2-3 models do so). and convert this extra voltage to charging current. This way you can use a cable which good enough for carrying current upto 9Amp (the maximum IMP of most Solar is much less than this) with just 2-3% voltage loss(usual expected voltage loss, you can reduce it further with higher gauge cable but that is not recommended).

If solar panels are wired in series the VOC is added up and allowance is given for increased voltage in winter. The maximum current from Solar panels to the Charge controller is the IMP of single panel.

e.g a panel has VOC 45 and IMp 5.43.The distance from you solar panels to charge controller is 20m :

you can wire 3 of these panels in series for a total of 136.2V VOC and Imp for the string will be 5.43A while VMP will be 113V. the wire sized required will be 2.5mm2 or 14AWG.

which is many times cheaper than 70mm2 or 00 AWG required if you wired these panels in parallel with a PWM charger!! http://www.solar-wind.co.uk/cable-sizing-DC-cables.html

For multiple string you can use either of these calculators http://www.midnitesolar.com/sizingTool/index.php or http://www.morningstarcorp.com/string-calculator/

Explanation 2

30% saving

Consider you total 900W system.

30% of 900 will be 270W.

Multiply that by the rate at which you bought the panels say Rs86/W

you will lose Rs 23220 on your system if you don't use a MPPT charge controller. :)

Explanation 3

MPP or Maximum power point

A PWM charger controller brings down the voltage of solar array to charging voltage of that battery. While a MPPT charge controller will convert that extra voltage into current which is used to charge the battery.

A 30V VMP solar panel connected to a 12V battery using a PWM will operate at 12-15V while the same panel connected to a 12V battery with a MPPT will operate at it's MPP voltage which will be around 25-30V depending on conditions at that very moment.

all are 40A. 22k is good price.

any warranty ?

it is good, but do get at least 1 year warranty.

don't buy without warranty.

iam confused abt cantoller...i want to buy mppt cantoler in display but epsolar no in display...any other good brand mppt in display...

epsolar pw model avlble in display..but u told me do not buy pw..

my budget is 22k

You will need a EpSolar Remote meter MT-5. It is sold separately. You can mount it some distance from the Charge Controller using the Ethernet cable. which you can't do with built-in display ;)

It is available with Saheen Solar.

Dear Yousaf,

I did not find epsolar charge controller in lahore. BEON solar is selling this product of 23500 rupees and nizam has not this model they have 4210 model so please guide me from where i can purchase this product in lahore with in cheap price.

Thanks

Sikander
