The reason your inverter (not converter) will not power up your electric heater, is because of the wattage of the electric heater
verses the output wattage of the inverter, without looking at your electric heater, I am guessing your electric heater
requires more wattage than your inverter is putting out. Most electric heaters are require at least 500 watts and many of them
go above 1000 watts depending on the size you are using.
If you look on the back of your electric heater, there should be a tag that lists the input- output power.
Your inverter should be running at a minimum of 250 watts over what the stated power consumption of the electric heater requires.
Also, you might want to consider running two deep cycle marine batteries as opposed to regular car batteries, the deep cycle marine batteries hold
a charge much longer than a car batteries do, they also do better in cold weather and have a higher crank output for starting cold engines on sea vessels.

Just a question to the group. Does anyone use electric heaters in there surveillance vans? If so can you recommend one. My surveillance van gets might cold in the winter. I have a chevy mini van and purchased 2 extra car batteries that I keep in the rear with a 300 watt 12Vdc 30A Max convertor. So far I tried 2 space heaters that would not even turn on. Any advice could be very warming. Thanks in advance, please email me off line.
