Harvesting module and power monitoring board

The harvesting module can be used both: as a standalone device or with the power

monitoring board.

In the standalone mode, leave the CN1 open and connect the jumpers as described below:



Close pins 2 - 3 of the J4 and close pins 1 - 2 of the J5 in order to supply the SPV1050

device by the on-board PV panel.



Close pins 1 - 3 of the J6 in order to connect the on-board battery.

It is possible to monitor the system behavior and efficiency by following the listed steps:



Place a voltmeter between pins 1 - 2 of the CN1 (VIN)



Replace the short on the J5 by an ammeter (IIN)



Place a voltmeter between the TP16 and TP8 (VBATT)



Replace the short on the J6 by an ammeter (IBATT)

The STEVAL-ISV021V1 kit includes the power monitoring board, and the related GUI which

runs on the Windows® XP and Windows 7 OSs.

The power monitoring board and the related GUI allow a quick and intuitive way to monitor

the system performances.
