Overview

Why this product

The Callsun 450W is a full-size, double-glass bifacial panel with 25.4%-efficient N-Type cells, for backyard ground mounts and larger off-grid setups. Its anti-shading layout keeps part of the panel producing when a corner is shaded, and the bifacial rear side adds output from light reflected off the ground.

Using it with a power station

One 450W panel (about 35.8V open-circuit) suits a 60V solar input. Two in series reach about 72V, which needs a high-voltage input such as the DELTA Pro 3's high-voltage solar port. At nearly 16A, the panel can also exceed the current limit of smaller inputs; the station will simply cap the current, so you get less than the full 450W.

Match the panels to your station's solar input before you buy: add up the open-circuit voltage (Voc) of panels wired in series and keep it under the station's maximum input voltage, and check the station's input current limit. Many stations need an MC4 adapter cable to connect rigid panels. Not sure what fits? Ask us and we'll match panels to your station, or browse our portable power stations.

Using it with the EZ1-LV microinverter

For plug-in solar, connect one 450W panel to each of the EZ1-LV's two inputs: two panels (900W) per microinverter, a close match for its 900VA output. Don't wire two 450W panels in series on one input; at about 72V they exceed its 60V maximum.
