4. Solar panels
4.1. General instruction
The solar panel should be put in direct sunlight, absolutely no part of it should be shaded, even partially. Ensure the panel is
placed in a location where no shading will occur at any time during the day.
The solar panel should be cleaned regularly; the dust can have a significant impact on performance. It can be cleaned using a
wet cloth or sponge.
The controller will operate only if the PV voltage exceeds the battery voltage (Vbat).
• PV voltage must exceed Vbat + 2V for the controller to start.
• Maximum open circuit PV voltage: 24V
All panels connected on the SHS 200 must be identic with the exact same specifications.
4.2. PV connection
The SHS 200 exists in two different versions: barrel and MC4 connectors. The difference stands in the connectors used to plug
PV panels. The SHS with barrel connectors is easier to install and more suitable for smaller PV arrays. The SHS with MC4
connectors enables to use of a larger range of PV panels which is useful for more powerful configurations.
