PV have maximum power 1250W, Battery 48V 100Ah. MPPT algorithm is P&O. Charger works with three mode : CV, CC and Floating. In this model we use Floating mode to store all of PV energy into battery.

Hi, whenever I run program it shows this error " Error evaluating parameter 'SampleTime' in 'CC_CV_Charger/Controller/I_CHARG/PID Controller' ". please help.

Please review the file because it has its mistakes

Hi, whenever I run program it shows this error Error evaluating parameter 'SampleTime' in 'CC_CV_Charger/Controller/I_CHARG/PID Controller'

Undefined function or variable 'f'.

Hi, how can I check if the system is operating at Maximum Power Point?

ReyTech

Thank you, the model is working. But there is a problem with the CV mode. It did not maintain the voltage at 58.4V (full charge) during CV mode. The boost converter duty cycle during CV model is always 0. Maybe you can have a look at it.

BTW. Thank you for sharing this model. It was helpful.

Hi,
I have the same error,
"Error evaluating parameter 'SampleTime' in 'MPPT_charger_V2/BATTERY CHARGER/Controller/I_CHARG/PID Controller'

Caused by:
Undefined function or variable 'f'."

Can you help us, please.
