Thought I would start a thread on this subject.
I found from experience that when you install an inverter
you need to consider how you want to use it. If you want to be on all the time and powering your outlets steady at a cost of amp hours added to your daily usage. Pure Sine Wave Inverters take between 2 amps and 7 amps to do there job . This is what it takes the inverter
to change 12v DC to 120V ac @60hz . This is without any load . So 24 hours of being "on" could cost you between 48 and 160 amp hours a day .
You really want to keep these things in "Sleep mode" !! In this mode most units send out a pulse or a low level ac signal looking for a load to turn itself on . We are talking milliamp's.
This is the tricky part most appliances
have electronic circuitry thats needs a constant ac source just to be able to turn itself on . I discovered this when I tried to use my inverter to power my domestic water
pump . I use a Headhunter Mach 5 pump , which is great but it is controlled by an electronic pressure switch . So if I leave the inverter in the full on mode it works , if I let the inverter sleep the pump will not wake it up and not work.
To solve this I moved to a mechanical pressure switch that will wake the inverter as the pressure in the system drops and turns it off when it has reached the desired pressure.
I also had to buy a microwave that had mechanical controls , or dials / knobs.
So it works like a switch, on and off , no clock , no electronic controls .
This allows the inverter to be in sleep mode 24hrs a day using milliamp's and only powering up when I have a big job for it .
Any one have similar experiences ?
