  • When installing in series or parallel strings user and installer must take precautions to ensure that the series model chosen can operate in this configuration. The user must follow Power Sonic’s recommendations for series and parallel installations, and it is recommended that the user or reseller contact Power-Sonic applications engineering for guidance. The warranty shall be voided if these actions do not take place or if the user does not properly maintain the string as recommended in the installation guides.
