Customer Questions & Answers

is this heater recommended on the mighty mule automatic gate opener solar kit where no AC power is available?

I'm concerned that If I hook this heater up to my solar powered gate opener batter that it will actually drain the batteries power
Asked by: miike
It is not recommended for solar applications. I suppose you could get around that by installing a much larger solar panel though. Here in Iowa, I gave up on the idea of using solar power for the gate opener and ran wire to the house instead.

It has worked so far (November, 2016) and our temps have been freezing at night. The reason for 4 starts is that it was rather difficult to get this to fit against by batter and have them both fit in the plastic housing.

Rated 3 out of 5 by from Tight fit but easy to install The battery heater doesn't really fit into the housing without bowing out the walls but other than that it is easy to install. Will have to wait for the temperature to drop to see how well it works.
