Data brief
Description
The STEVAL-ISV021V1 is a demonstration kit
which consists of a complete energy harvesting
module based on the SPV1050 ULP energy
harvester and battery charger, having the purpose
to show the electrical performance of the power
converter and many other fundamental electrical
quantities related to the overall system.
The power manager is configured as a buck-
boost converter, fitting the electrical
characteristics of the mounted PV panel and
battery.
A power monitoring board along with a software
GUI are used to monitor and to graph both of PV
panel and battery voltage and current, and
system performances like MPPT accuracy and
conversion efficiency.
The STEVAL-ISV021V1 represents the
standalone harvesting module that can be
interfaced with a wireless sensor node to provide
the microcontroller, transmitter and sensors with
the energy scavenged and stored into the battery.
Furthermore, the STEVAL-ISV021V1 embeds an
extension connector to interface and to monitor of
some of SPV1050 input and output signals
through a microcontroller based board.
