On our boat we have a Victron phoenix multi plus inverter 12 2500 120 and seem to have a random fault which cuts it out maybe once a day - all three red LEDs come on at once - Overload, Low Batt and temperature. It is in the engine room (not ideal, I know) but has not been over 40 °C since last summer. I plan to rig a fresh air duct to feed air in below it before this summer. I don't see this fault in the manual I have downloaded (can't find the actual manual on their website): https://www.victronenergy.com/Manuals/PhoenixMulti/UKISM010004000-rev08.pdf
Anyone have experience of this, please?
