Can the Power Inverter 1000 Watts with Three AC Receptacles Be Used to Power Equipment for 10 Hours

Question:

Would this be a good choice for me? I have a 2018 Jayco Jay Flight SLX Trailer with two Interstate batteries, model # M24DC Lead Acid. I need to know if these two batteries along with the WC3720 could handle a 60 watts/hour load for 10 hours a day for 3 days total with no recharge. Needed for medical devices at night. No other loads will be added to this inverter., although the LED interior lights will also be pulling 12 volt power off the batteries for a couple of hours a night, apporximately 36 watts. Batteries are rated at 81 Amp/Hour. They are wired in parallel so the voltage remains at 12 volt. I am concerned that I have enough power in the batteries to run both the inverter and the stated load for the time stated without fully depleting the batteries.

The Power Inverter 1000 Watts with Three AC Receptacles # WC3720 seems like it would work for your application. But, you will need more battery power to accomplish what you are needing to do. You can only deplete your lead acid batteries 50% before you start to damage your batteries.

Since you have 12v batteries you will be using 5 amp hours every hour (60 watts divided by 12v = 5 amp hours). Since you are needing to run this for 10 hours, that equals 50 amp hours, since you can only deplete your batteries to 50%, you are looking at about 1-1/2 days of run time. In order to have the proper battery power, you would need to add two more batteries in parallel to accomplish what you are needing.
