Here is my setup I have two deep cycle 75amp hour batteries wired in parrallel (12volts) powered by a seperate 100amp Ford Alternator. This system was working fine for the past couple of weeks. I am running a 14" lcd (3amps at 12volts) and a anthlon 2200 with a 250watt power supply off a 300 watt continious inverter. Tonight the inverter started squeeling really bad and had problems delivering power to the computer. .... strange the inverter is old so I went out and bought a new 750watt continous inverter wired DIRECTLY to both of these deep cycle batteries and it starts squeeling and giving battery errors tooo!!!!!! but only with the computer on...?!?!?! very strange so I figure cheap power supply since hte power supply buzzes even with everything is off but the inverter. I have replaced it with a 425 watt $99 power supply , haven't tried it yet... ideas? is it the power supply? what is causing this, the computer works fine inside (off house power) even on that old crappy power supply... I have run many power supplies off "modified sine' inverter with NO problems for years? is this one just super cheap?
No announcement yet.
Low power alarm, kind of
