I recently installed a Charger 1 in the bed of my truck (Ridgeline) to power my EB3A and pass thru to power a small ICECO GO 20 frig. It’s all under trim fold tonneau cover. Worked fine when was cooler but when the Texas heat started the EB3A would give a temp notification and shut off DC charging. I installed an Inkbird wireless thermometer to monitor the temp. EB3A specs say max charging temp is 104 degrees. Temp gets higher than that. Any ideas how to work around it. Leaving the last fold of my tonneau cover up didn’t help.
The EB3A is quite temperature sensitive. I have mine in a cabinet as a UPS for my networking equipement, and when I left for vacation and turned off the AC in the house, it shut down because it over temped and stopped charging. It was around 27C in the house at that time, but perhaps 35C in the cabinet. I realized that this cannot be used as a Ups (despite how it was promoted) because if the power is out, and this runs out of battery, it would not reactivate DC/AC output when power comes back on and it recharges.
I eventually solved this by gluing a USB fan plugged into the USB plug on the vent so it continually blow air into it. Requires 2-3W of extra power, but seems to have done the trick.
Is the fan running? Can you position the EB3A in somewhere that isn’t as hot? Maybe you can plug in a small USB fan into the USB port and run it to circulate the air with the last fold of the tonneau cover open?

Hi @rcarlson1957, Generally speaking, during operation, the internal temperature of the power station will be higher than the ambient temperature, which may cause it to shut down due to overheating.
We appreciate @snowstorm’s advice, they are very helpful!
We recommend that you take heat insulation measures, turn on the air conditioner, or enhance heat dissipation. We hope this will be helpful.
Great idea! I’ve stalled computer fans in camper for my 3-way refrigerator and they really helped. Using a USB fan on side of EB3A sounds like it should help it keep cooler. I’ll give it a try.
