So what is the draw when the compressor is running and what percentage of the day is the compressor running.
Until we have a fair estimate for that, any numbers being thrown around are wild guesses that may or may not work.
Let's run some sample numbers and you can update based on your real life numbers:
- Assume 3amps at 120v when the compressor is running
- Assume 50% duty cycle
I realize this wasn't intended to be realistic, but it's worth noting that modern fridges do not use anywhere near 3A running. (Starting power is a different matter altogether.) A not unreasonable rough estimate, lacking any better data, might be around 1 kWh per day or so for an ordinary sized, fairly basic residential fridge. Often the dorm sized fridges do not use very much less energy, despite being much smaller.
An absorption fridge running on AC power uses significantly more energy, maybe around 3-4 kWh per day.
