I just recently got a 1200 watt power inverter as a temporary backup for my 1/3 horsepower sump pump. The sump pump is rated 8 amps at 105 volts so I believe the max power it uses is 960 watts. I used a kill-a-watt meter on it and found that when it is running it is using on average 580 watts although I'm sure its much more when it is starting momentarily.
I was wondering, would I be able to use a pair of jumper cables to connect the power inverter to my deep cycle marine battery? I mistakenly believed that this power inverter would come with a pair of cables but it did not.
Edit: Also, I see that there is a voltage and overload protection built into this power inverter so I was wondering would I still need another fuse or would that not be necessary since the sump pump will be the only thing connected to this inverter and it would only be used temporarily in the case that I lose power.
