I Want Learn How to Install 1.8 KW Power Pack

[athar.walile]

Hello Every Buddy

This is Athar from India. I have purchased Solar Photo Voltaic Modules of 1.8 KW. The SPV specification is as follows.

Number of SPVs : 15
Pm (maximum power) in WP : 125
Voc (Oper Circuit Voltage) in Volts : 21
Isc (Short circuit Current) in Amps : 8.4
Vm (maximum Voltage) in Volts : 17.1
Im (maximum Current) in Amps : 7.3

I have 2500VA (@ 0.8 Power Factor) Grid Tie Inverter. DC input of inverter is 48V/36V.
I have four 180AH 12V batteries.

How can i connect these SPVs to my inverter? Can any once help me creating circuit diagram for this project? Do i need Charge controller in this scenario. How many SPVs will be connected in series and how many will be connected in parallel.

Please help me in this project.
Thank you

Welcome onboard and thanks for joining.
I just read your post today.
Yes you need a charge controller to connect your panels to the batteries. So it can controll the charging.
We need to know how many wh or kWh you use daily and
we can calculate the system.
We need to know is it for grid tied or off grid (to calculate baterry)?

hi, this is saifi, i did not find place to post my question, pls dont mind and reply, since i also have same question.



Number of SPVs : many
Max system volatge: 600 volts
Pm (maximum power) : 22.058 watts
Voc (Oper Circuit Voltage) in Volts : 21.56
Isc (Short circuit Current) in Amps : 1.50
Vm (maximum Voltage) in Volts : 16.54
Im (maximum Current) in Amps : 7.3

I have 500VA Inverter. DC input of inverter is 12 /24 volt
I have four 180AH 12V batteries.

daily consumption of power : 400 watthour

How can i connect these SPVs to my inverter? Can any once help me creating circuit diagram for this project? Do i need Charge controller in this scenario. How many SPVs will be connected in series and how many will be connected in parallel.
Thanks
plzzzz help.

Huh? Why bother with such a small power usage? All you need it 1 panel and 1 battery.

Huh...hahahah!
