Re: PIP-4048MS inverter

I don't think changing the minimum solar voltage (if possible) would make any difference to the situation. I still think there may be a setting's conflict that tells the the relay drivers to stay on. (expecting soler power to still be available) That is the situation I had, I also had an fault code ...

Re: PIP-4048MS inverter

Had a similar experience. I have used the PCM60X charge controllers for years now, as I use it along side the 5048HS And have had no problems with them on (custom settings) with the lithium battery bank. Just a few times where I disconnected the solar panels late in the afternoon just before a storm...

Re: PIP-4048MS inverter

HI Coulomb I had an idea there would be many different factors involved on different applications, anyway I'm still learning these things. The other night I had a look at the IGBT gate drive on the PIP4048 main board using a microscope and found either a crack or short across the resistor (R139) tha...

Re: PIP-4048MS inverter

Yes around the active and neutral leads together, there may be other ways to do it but that was quick and simple for me at the time, I think its to do with spikes from PWM controlled devices. (affects other types of inverters as well) Anyway I have to say thanks Coulomb, Weber and others for the inf...

Re: PIP-4048MS inverter

Hi All Today we fired up the new PIP-5048, working good the fans run all the time unlike the earlier version's And they have finally put the fans in the other way round, now they draw the cool air in through the bottom and the heat comes out the top, As it should. The IGBT's on the High Voltage side...

Re: PIP-4048MS inverter

Well overheating would be a possibility if you were charging on a really hot day? I have measured 60c air temp coming of the fans last summer. However i think there may be something els going on. It looks as if it just shuts off without regulating properly We use a PIP4048HS and PCM60X MPPT charge c...
