PV-Battery - comercial "electricity load from battery"

Good day.

this is to ask for advice about the use of battery storage and battery dispatch in within an modeled pv-battery comercial system. 

I using a photovoltaic system together  with its respective inverter that generates 2.900 kWac output, in order to deliver that energy to a charge that in practice is a motorbomb. I make the calculation, select the chemestry and set the parameters, so that the battery has 1.792 kW/h (DC), 51.2 V and a capacity of 35 ah. I configurate the battery dispatch with the data you see in the attached image and use the manual dispatch in order to use the battery at the specified times as you can see in the image. However, when simulating, the system when delivering the results shows that the electricity to charge the battery only delivers 0,3 kWh as maximum peak at the set time and I need to deliver at least 60% of the total value of the battery’s power capacity for an extended time. 

I ask you to help me to resolve this doubt, I would be very grateful.

Hi Giovanny,

Perhaps the battery discharge is being limited by the Max C-rate of discharge. If you use the "Set desired bank size" option to size the battery bank, then the maximum C-rate of discharge is the bank capacity in kWh divided by the bank power in kW. If you use the "Specify cells" option, then you set the maximum C-rates of charge and discharge as an input.

Please feel free to attach a copy of your .sam file for me to review if you still need help.

Best regards,
Paul.

Good Day Paul.

Thanks to given me that advice, i will work with that information and expect better results, thank you. 

I attach the .Sam file to you. So you can do me the favor of reviewing my work and helping me with that problem if I can’t do it on my own. Thank you very much. have a good day.
