NEW DCDC's crazy hot. Low output.

Brand new out of box. 3196s. Software is up to date. Two DC dcs Orion tr smart 12 12 30 providing only 36 amps in bulk (combined) to lithium batteries at 20% soc. Batteries are fed by over 150 available amps from two alternators. Input voltage is 14.5 output is voltage is 13.3, Case temps are over 150*F easy and ambient temp is 73 degrees. All wiring is oversized. What needs to happen here to get the rated output I paid for?

When these units overheat, output is derated.

Assuming wired correctly.

Are they mounted vertically with good ventilation?
