Rainy day in NH.
Thought I'd make some measurements of Inverter current drawer. As most know an Inverter takes 12 volts, typically from your battery
, and converts it into 110 Volts AC. 110 Volts AC is what you find at most home outlets.
My goal is to measure how much the Inverters devices draw from the battery
under no load conditions, with nothing plugged into their AC outlets.
We have five Inverters; 2 of them are 100 watt Inverters
Interestingly the 400 watt Inverter, the biggest of the three I tested, drew the least when attached to the battery
and nothing plugged into it's AC outlets. (It is not presently easy to test the 1200 watt Inverter but I will when I get my watt meter.
100 watt Inverter draws 0.3 amps
200 watt Inverter draws 0.35 amps
400 watt Inverter draws 0.1 amps
1200 watt Inverter draws ???
After looking at their current draw with nothing plugged into their AC outlets I loaded each Inverter with our LCD TV, electric blanket and Dish satellite receiver to see what the Inverter draws from the battery to run these devices.
Our Sylvania TV drew about 3 amps from the battery, indicating it uses 36 watts.
Our Sylvania twin electric blanket drew about 5 amps when fully on, indicating it draws 60 watts when fully on.
Our Dish Satellite Receiver draws about 1.2 amps when fully on, indicating it draws 15 watts.
15 inch Sylvania TV draws 2.9 amps from the battery.
Twin Electric Blanket draws 5.5 amps from the battery.
Satellite Receiver draws 1.2 amps from the battery.
For comparison an individual LED lamp draws about 0.2 amps from the battery.
All 7 LEDS 1.4 amps from the battery.
