You gotta be in Australia right? I got the exact same inverter from dicksmith elec a week ago and I was very happy with it. I use it hooked up to a second battey in the boot, connected in parallel with the main battery and an ITPS as startup/shutdown controller, with bypassed the regulation. My computer now survives cranks for the first time and I was getting very excited. I set the power management to laptop/portable computer and it did an excellent job. Last night however I had no computer in the car,weird enough, and this morning i couldn't even start the car!!! drained batteries... I always left the inverter running 24hrs and it was probably pushing the batteries too much(not too sure about this).Originally Posted by coma
A guy told me at work that even the voltage does NOT go below 10 v (inverter shuts down/protection -10V) it still draws a lot of current and not leaving enough power to star the car engine..
A quick solution is to install a remote switch from the inverter built in switch to the dash.
Apart from that, after having the switch, i'll be able to run a lot more devices that the opus very easily. I would recommend the inverter over the opus. Noise can't be an issue when you have a noisy car and a sub woofer anyways.
