often the fridge/freezer will have heaters around the door openings to prevent condensation while running. I believe these are independent of the defrost function. they often can be turned off by a switch inside or on the front labeled "energy saver" or something similar. this features controls condensation around the doors on the exterior of the unit. needed in humid enviroments(outside, garage, porch etc...) often not needed inside homes with airconditiong. thee heaters will make it feel warm to the touch.I remember you giving these figures in a previous post and being amazed at your amp hr usage. Please remind me what size your battery bank is and the actual amphrs. used in a 12 hour period. We typically use 225 amphrs. in a 12 hr. overnite, in a cool 60deg environment, to mainly power our 120v 10cu.ft (225 liter) fridge and 120v 5cu.ft. chest freezer. I did discover that our fridge seems to always be on defrost-I can constantly feel heat around the freezer door opening. I attribute this to the defrost timer not playing well with the modified sine wave inverter and being one of the reasons I am switching this year to a pure sine wave inverter. I tried disconnecting the timer, but this played havoc with the air circulation system becoming clogged with frost in just one day.
Thanks, Tator
I would not expect the defrost to warm up the freezer enough to make it warm around the doors.
