Just purchased this unit brand new. Charged it over night and I am now running my computer and monitor off the unit. Only one hour in, I had two events a couple seconds apart. The unit switched to battery for a second, then back online, then back to battery and back online. I'm only drawing 120-180watts. The house is old(built in 79). Can this be an electrical problem? I never had my PC shutdown unless there was actual power interruption. So what does this mean?
