Inverter refrigerators and their interactions with search mode energy conserving DC /AC inverters
A question was recently asked [email protected] Parkinson about the search mode of inverters and their interactions with a LG inverter refrigerator, although mine is a Panasonic the tests I conducted may relate to some/all inverter appliances.
Including others, such as switching transformer led drivers.
The experiment proved, in my case, that the refrigerator would not wake up the inverter even if the wattage was set to its lowest setpoint of 5 watts and the widest pulse of 25 seconds, other settings were tried. At 10 second pulses the interior light remained on at all times, obviously powered by capacitors, at 25 sec. It would turn off momentarily.then the pulse would change the capacitor.
To increase the load I turned on one led light fixture, it just illuminated during the pulse, turning on 4 did nothing no illumination and the inverter remained asleep. Which is a bummer, all these wonderful energy saving devices and they don't work with an energy saving DC/AC inverter
The experiment was using a Schneider SW 2524, so the results may differ with other brands, so for now I'll just program a block invert time say around midnight to 5am, until a solution, which I will come up with, sooner or later, is found.
