I have a load 15000 W,running time 09:00 am to 05:00pm in day ,I will use MPPT charge controller ,what will be the battery bank size? Batteries will be either required here or not? please guide me

you will need battery pack as both the PV generation and consumption are not uniform during the day.

Dear Ravinder :
yes i need battery pack as both the PV generation and consumption ,advice??

Hi Yasir,
On basic grounds you would require a battery, but
Have you checked the system size?
Do you know the exact consumption on hourly basis?
the information provided seems to be too less to analyse.
Kindly send the details on kapil@rkvgroup.in

Hi, Yasir, so you want a solar& battery hybrid energy storage system? Do you need an off-grid function for this system?

Yes GMDE
I need have available only solar and batteries ,there is no grid

Yasir, were you able to get a response on the battery configuration that you would need? If not send me an e-mail at aaron@paradigmsolarllc.com

please refer to our SGS150 at our website. You will get everything you are looking for.

Hi, Yasir, if you can send more detailed information like the annual irritation of your instalation, the more specific requirments of your system, we can recommend a suitable system design and PV/Battery configuration to you. As you see, there is no grid, the total power consumption is 120kWh per day, all those energy are produced by the PV. But the PV power is influenced by the irration timely, so without the site irritation, it's hard to decide the battery size configuration.

Hi,Yasir .According your information , this system is a off grid system , so I think you need batteries to store power. As we know that solar system generate power at peak sun radiation , almost 4-5 hrs per day , but you need to use it at 9am to 5pm , so in the early morning , the system can't satisfy your load , we need batteries to store power to supply your load .
According my calculation , your load 15000W , need at least 28KW to 30KW solar panel to afford your consumption. For batteries , I think you need 30%-50% of your consumption ,it need around 40 pcs 12V 200AH Gel batteries .
If you need more discuss , pls contact with me , sales09@bldsolar.com
We are manufacturer of solar module , off grid solar system .
Best regards
Roger

according to the load, we advise using 96V system, you need 10pcs 96V 200AH battery
