My old converter was only 1 stage, so thought I would upgrade to help extend the life of my batteries in the RV.

The instructions could have been a little more detailed, but were adequate. It fit in the place of my old converter very easily. Most of the problems were with trying to get the old converter out. All the DC wiring was soldered to the circuit board, on the old unit, which made it a pain to take apart. The new board has screw lugs, which made the job of connecting the old wires very easy. After letting it run for a day, I thought the 4 state converter was not working properly. After checking what the lights meant, and waiting for 15 minutes, it switched into the correct state. Apparently, I just caught it at the right moment, when it was in DESULFATION mode. It has been working fine for several weeks now. Have not had time to take it out on the road yet. Wanted it for a two month cross country trip this fall. I would definitely recommend this to anyone replacing their Magnetek/Parallax 6300 or 7300 series. The charge wizard should help keep the batteries from stratification, with its DESULFATION mode. The RV is now parked outside, and last week it was around 100 degrees, and I still have not heard the fan come on, so cannot comment on its noise level. It came well packed, and actually arrived 1 day early.

The PD-4645 converter only took a few days to arrive. Instuctions were clear other than they mentioned removing a red wire and I did not have any red wires. There were two black wires. Installing the DC Districution board was easy but getting the smaller gage (thicker) wires) branch circuits into the connecting slots was difficult.

Installation of the new converter would have been easy if I had read the tag on the leads. What were DC + and -, I read as AC and I hooked it up that way. Tripped breaker. I thought unit was defective and got a new one, in fact two, one from the manufactfurer. After the third unit tripped the breaker I knew it had to be me or my circuits and then I realized the leads were maarked DC not AC. Dumb and lucky! Once I had that figured out the unit worked perfectly. Easy to install.

I have not had the opportunity to see how unit works but it is very quiet.
