When matching solar panels to a water pump system, the specific brand of the panel is secondary to its electrical characteristics. The critical engineering goal is to ensure the total Vmp (Voltage at Maximum Power) of the solar string falls within the inverter’s peak efficiency window, and the total string Voc (Open Circuit Voltage) remains safely below the inverter’s maximum DC input at the site’s lowest recorded temperature.<\/strong><\/p>\n

1. The “Panel-Agnostic” Advantage<\/h2>\n

Chez HOBER, notre technologie de solarisation des pompes \u00e0 courant alternatif est con\u00e7ue pour \u00eatre Ind\u00e9pendant du panel<\/strong>. Que vous utilisiez des modules monocristallins, polycristallins ou les tout derniers modules bifaciaux \u00e0 haut rendement d'un fabricant mondial de premier plan ou d'un fournisseur local, les performances du syst\u00e8me sont garanties tant que le dimensionnement de la tension est correct.<\/p>\n

Conseil de l'installateur\u00a0:<\/strong> This allows you to source the “glass” (solar panels) locally to save on shipping costs while relying on HOBER for the system’s “brain.”<\/p>\n

2. Le ratio de dimensionnement : pourquoi 1,4x ?<\/h2>\n

Une erreur fr\u00e9quente consiste \u00e0 associer des panneaux solaires de 7,5 kW \u00e0 une pompe de 7,5 kW.<\/p>\n
