Photovoltaic (PV) panel, and can minimize energy losses and extend the operating lifetime of a PV system. The Raycap ProSMS 8 string monitoring solution has some unique and innovative features in comparison to basic string monitoring solutions. These include: •...
Page 7: Installation
ProSMS has an advanced built in mechanism that recognizes settings change and sets internal parameters to match the settings immediately when settings are changed. This also applies to baud rate and parity change. 2017 ©Raycap • All rights reserved 130 620 300 Rev.C 171116 www.raycap.com...
Page 8: Cabling Recommendations
• Cables with lower cross-sectional area may be used for installations where less than 20A per string can be expected. String output connections (COMMON) • When ProSMS 8 is operating at full capacity (30A per string, 240A total), four 16mm tinned double insulated fine stranded cable (without ferrules) is required •...

Page 13: Prosms Settings
• Any valid MODBUS address between 1 and 247 can be selected using the on-board DIP switches. The switches are 2 binary coded. Address on each ProSMS 8 is factory preset to Nr. 5. • Address can be changed during operation, no restart or power cycle is required.
Page 14 • Settings can be additionally locked. When locked an accidental change of switches has no influence on the configuration. System reset (DIP Switch 8) • Hardware reset of ProSMS device (does not effect any settings or saved values). 2017 ©Raycap • All rights reserved 130 620 300 Rev.C 171116 www.raycap.com Page 14 of 24...
