Hiya Guys,
I have recently installed a 2000w modified sine wave Inverter in my van to operate my Air Conditioning tools (Sick of running out cable power)! I have the usual, vacumm pump, recovery unit etc.
The thing is...everything works fine apart from the recovery unit! On start up it fails to initiate to fire up and run, just a kind of slow clicking motor sound.
I have read up on some articles on the net without any success. I`m guessing due to the recovery unit being motor, pump operated it is sapping too much battery from the installed 110ah battery source that runs from the van battery in turn to the inverter by means of switched relay.
I have read that tools of this nature require a pure sine wave inverter but do not understand how it does in fact operate the rest of the tools including the vacumm pump.
The recovery unit operates at 480watts max output drawing 4.2 amps so I would think that the set up I currently have would be more than sufficient to operate correctly.
The inverter does for a short time supply 4000watts peak for a couple of seconds.
I have looked at calculations on line and the inverter once again does indeed appear to be capable of operating units of this nature taking into account the output of the inverter.
It is the pure sine wave thingy that is putting me at a bit of a loss.
It would be good if anyone with onboard power could direct me in making attempts to resolve this fustrating issue!
All the best!
