4.3.2 Ventilation Design
The upper part of TC500K3US-O is the air inlet for cooling air to go into
and the lower is the air outlet to discharge hot air.
The air inlet of the head cover is equipped with a removable
dustproof net and insect net, which need to be cleaned regularly.

4.4 Circuit Introduction
Direct current generated by PV array is converted to alternating current
through inversion in the inverting module of TC500K3US-O, and then
becomes sine wave through the filter and is then fed to the grid via the isolation
and step-up of an internal three-phase transformer.
