Product overview
This bifacial 400 W set uses two 200 W N-type modules in a layout promoted for improved shade tolerance. Separate modules provide flexibility for roof placement and for configuring the array within a compatible controller’s input limits.
Suitable applications
RVs, vans, boats, home rooftops and off-grid systems designed around the modules’ verified Voc, Vmp, Isc and Imp values.
Before ordering
Confirm Voc, Vmp, Isc, Imp, dimensions, weight, connector type and mechanical-load ratings from the current datasheet. Size the series/parallel array so it remains inside the charge controller or power station input limits in all temperatures.
