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

Hello again guys, is there any way to change the min.solar voltage from 40 vdc to 55 vdc? What do you mean by the min solar voltage? What makes you think it can go down to 40 volts? My understanding is that the minimum voltage on the solar inputs that the PIP's SCC can maximum-power-point-track, is...

Re: PIP-4048MS inverter

is there any way to change the min.solar voltage from 40 vdc to 55 vdc? There are only half a dozen commands that the main processor sends to the SCC, and none of them affect the minimum PV voltage, at least not directly. So you'd have to patch the SCC code. Possible, but a lot of work. Why do you ...

Re: PIP-4048MS inverter

But I think that you're saying that the SCC relay coils (there are two in parallel) are turned on somehow. That would require of the order of a watt, which is some 20 mA at 50 V, and would require more than that (a few watts) to drive the SCC processor and associated electronics as well. But I can'...

Re: PIP-4048MS inverter

or the scc? Oh , and it seems that i find another bug // When pv panels are connected , in the normal way , when a heavy load occurred , the scc , disconnect the panels, and then reconnect them , but now , is making some strange relay noises and the pv panels stays connected , even when heavy load p...

Re: PIP-4048MS inverter

any idea how can i stop this ? or, where to start ? If you have the ability to inject commands to the PIP, and since you are using patched firmware, I'd try this pair of commands: MNCHGC0500 <CRC><CR> MNCHGC0499 <CRC><CR> This sets the dynamic charge current to zero, then sets it back to the EEPROM...

Re: PIP-4048MS inverter

Ok so i understand that -1a in bypass mode is not necessarily a problem , but the leakage is real , do you have any idea how can i stop this ? or, where to start ? Thank you ! ps i use the firmware ( 73.00c) , should i update ? and i have updated after the problem with the pv input , but no fix .

Re: PIP-4048MS inverter

And measured with a multimeter , even with the pv switch off , i have that 46v there , By "there", do you mean at the PV input terminals? Is it possible that this is leakage across your PV switch? For example, can you ever see this 46 V at night? so , somehow is taking dc current from another place...

Re: PIP-4048MS inverter

And , this night , in bypass mode , i have a 1 amp battery draw .... so , is like somehow , the same thing is drawing this current it takes it to the pv input .

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 stor...

Re: PIP-4048MS inverter

Is there any way i can change when the pv input to turn off ( like under 60w or something ) ? Thank you guys !

And measured with a multimeter , even with the pv switch off , i have that 46v there , so , somehow is taking dc current from another place . I have found another way to turn it off ( the panels ) is by setting the max charge to 0 am and then back to desired amp . After it disconnect that relay , is...

Re: PIP-4048MS inverter

Yes, I have a Pip4048ms .... the problem remains even when the battery is removed. the relays seem to work well in the mppt card but not released under the 60v photovoltaic input Hi , did you solve the problem? I have the same issue , He worked great , until now .Thank you ! If you mean that the re...
