the 2:1 transformer also offers ac isolation. im not so sure id want the hot line of 120vac, via a diode, on the dc part of a system. this configuration (known as the "DT Kludge") was a common (and expensive) workaround for outback fx series inverters which unfortunately only had one ac input

HI Jerry, Just a standard bridge rectifier, with correct amp rating. AC to diode to CC, thats it. All regulation is via CC. jay On Dec 15, 2014, at 7:30 PM, Jerry Shafer wrote: > Very interesting, what diodes did you use to rectify the AC, it sounds > similar to the wind machine designs I h

Very interesting, what diodes did you use to rectify the AC, it sounds similar to the wind machine designs I have worked with. Do you use a coil to regulate the AC amps to the diodes, it seams like you would need a "throttle control" the current someway besides the diodes them selves or the CC. Jer

Hi Kirk, If you use a 200vdc midnight CC you'll have no issues. When you rectify 120vac its up around 166vdc ( uses the peak vac which is around 170vac.) For a 150vdc max controller ( midnite 150) or a 144vdc ( outback FM) then a buck transformer or standard transformer is the trick to reduce t

My challenge is determining the correct 480V configuration so I can use a 3-phase Solar Edge 1 for a 12KW commercial system. The SE10K requires a 480V Wye configuration. The main 480 panel looks straightforward. L1, L2, L3 come from below grade to three separate busbars in the panel. A 4

Larry, I have not found a battery charger nearly as programmable as the chargers in inverters are, and I've sold a number of inverters over the years which were destined to be used strictly as battery chargers. This is actually a great use for modified-square-wave inverters. The Magnum RD2212 has

This has been discussed on this list in years past. It is possible to use an outback charge controller as a battery charger. You need to put the 120 AC into a bridge rectifier, then feed the 120 DC into the controller’s PV input. So you’ll have an 80 amp battery charger. Kirk Herander VT S

The way I would do this if using outback (really what I'm familiar with) is to set up the aux relay on the inverter to trigger an AC relay that connected the grid to the inverters ac input using the "load shed" function.
