Experimental results

In order to test all the functionalities regarding the MPP tracking, and battery charging

capability, the following parts are used:

●

Two SLA batteries (12 V, 4 Ah), connected in series

●

A solar array simulator (SAS), that allows total emulation of a PV panel electrical

behavior

●

Four multimeters, to check the voltage and current values in the input and the output of

the STEVAL-ISV005V2, to evaluate the MPP tracking efficiency, such as the power

efficiency, and obviously to trace the battery charging curve.
