MSP430F5132: MPPT PMP7605 programming issue

Vishnu,

Un-commenting the code you mentioned will add code for Battery Charge Profiling for lead acid battery (code tested on lead acid batteries).

Hi,

Thanks for your help.

I am testing this program with 24V panel, and i am using 24V, 26AH lead acid battery. So i will test with un-commenting that code which i have mentioned above. and what changes i have to make for getting 24V, 6A output in below mentioned constants.

#define CC_LIMIT 350
#define CC_TO_CV_LIMIT 610
#define FLOAT_VOLTAGE 590
#define BATTERY_CUTOFF 440
#define BATTERY_RECONNECT 480

Thanking you.

Vishnu,

The numbers are dependent on the voltage and current ratings you want to implement and also on the hardware components you are using. You can calculate appropriate numbers are replace here.

HI,

 Am using the same schematics and same components mentioned in TI site.

Need to charge 24V/26AH battery. with 10% current of battery AH. Panel is 24V panel.

Is there any changes that need to be done in the schematics or code side?

Thanks.

Vishnu,

This hardware design supports 20A currents which means for your levels, you will be operating at lower levels than it was originally designed for. You will lose accuracy because of this (assuming keeping the hardware as is). 

For code, you can look at the comments against the #define numbers and change appropriately. 

Thanks, Jasraj
