Yep that's exactly what it does. lol. Always amusing when people make the comment.. "But my engel ran for.." Best thing you can fit if you have or buy an engel is a low voltage cutout to protect your battery. If it is drawing it that low you need to look at alternatives such as more capacity solar/gen set etc.
We have had a few engles pass through with the same issue, around the same vinatge. Perhaps a batch that weren't quite right, who knows.
As said before 90%+ of the times we get a "My *** fridge doesn't work" (pick whatever brand you like) it comes back to the wiring, often despite several discussions along the lines of... an auto electrician fitted mine, nah can't be it's all new/good/properly done etc etc. Not uncommon to then find there is a 1-2 volt drop on the circuit, especially under load.
