Hello georgelesley. I have not seen any reference to a battery cutoff switch in my documentation. Nonetheless, I will look again. Could you be more specific as to the location under the counter. I have a 70X but I have not noticed any such switch. As well, could you please expand upon your comment about the inverter. Should the inverter be turned off when not in use. Should it only be used to run TV and the dome satelite attached.? I am obviously a Newby and having problems understanding the proper use of the inverter as well as the purpose and linitations of the generator. Thanks again!
