Struts
When installing modules on struts, select struts and module mounting brackets that can withstand the expected local
wind. The struts must have a solid foundation.
Ground
Select an appropriate installation height for ground installation to prevent the lower part of the module from being covered
by snow for a long time in winter. Install the modules on a support of an appropriate height. Do not lay the modules directly on the
ground. In addition, ensure that the minimum part of the module is not less than 900mm to avoid being obscured by plants or trees,
to avoid being damaged by blown sand or being obscured by soil splashed by rain.
Wiring
Hyundai Energy Solution provides recommended connection modes for customers. If the connection modes required by the
installation personnel are different from the recommended connection modes, please contact Hyundai Energy Solution commercial
personnel to evaluate the feasibility of connection modes.
Photovoltaic modules can be connected in series to increase the series voltage, and connected in parallel to increase the series
current. Please select a reasonable connection mode according to the electrical parameters of the inverter selected by the
photovoltaic system and the maximum system voltage of the modules.
When connecting cables, pay attention to the polarity of the positive and negative terminals of modules.
For different types of components, Hyundai Energy Solution provides optional wire lengths to match different system
wiring methods. The following table describes the recommended system cabling methods.
