Re: PIP-4048MS inverter

With parallel inverters the current settings are not linked I have to set charge settings on each individually in a way I can see some reasoning behind this The SCC may have different numbers of panels The AC chargers may not all have grid/generators attached But it could have been another command f...

Re: PIP-4048MS inverter

Just in case anyone doesn't know, our patched firmware for the PIP also fixes that problem. Not totally it is indeed much better, but it will cut off if a large load is applied to the inverter for a period of time thus spending too short a time in bulk , whereas the eSmart remembers its not been at...

Re: PIP-4048MS inverter

If you just want more solar charging there is the option of two solar chargers in the new PIP series or you can do the same as I have and get another external charger , I have the eSmart 3 130volt MPPT charger working with my PIPs it provides 40 amps and is working well with the inverters , it is ev...

Re: PIP-4048MS inverter

Computer control easy I can do that already , you only need a relay with 4 poles less than $5.
Do you want control with a web page so any device can be used eg smart phone?

I would use a 4 pole switch and 8 wire cat5 cable you can do 4 that way.

Re: PIP-4048MS inverter

I have been running the Pb version of the patched software on my two parallel PIPs for a couple of months. They still tend to go back to float a bit early. I have just installed the 130v version of I-Panda 40a MPPT charger on the battery so now I have the two PIP 60A chargers and the I-Panda 40A The...

Re: PIP-4048MS inverter

The description sounds like something shutting down due to heat. Now I know that the heat sinks get to over 50c and this caused me to install external 120mm fans to keep them below 43c and I also think the capacitor failure is due to this heating them. So do you have any way of getting more air thro...

If you are going to bench test the board before replacing into case and have access to a CRO would be good to see the ripple on the caps.

I will add to Roberts use Grid or Generator not AC look at what terms they use in the hand book.
Also do not use other abbreviations F/W and do not write long sentences.

Hello Robert welcome. How old is your 4048 do you know what went wrong it may be repairable. Also how old are your batteries what are they? As far as reliability for the PIPs the newer ones should be better they have made a number of changes. I have found 18 x 250 watt panels to be the minimum on my...

You also need to look at what the power factor is with the generator
How old is the generator?
Also if you can get to it without too much trouble test the capacitor in the generator they have a habit of slowly dying.
Having an oscilloscope across the output it would be good to see the waveform.

I watched your video 54 hertz is a bit too high and it appeared to drop the load on the generator when the frequency dropped, with the grid a 1 hertz drop would be a big problem.

The problem I see all the time is the poor understanding of how sealed lead acid batteries are to be charged and discharged. Most people think they can treat them the same as flooded batteries so they charge and discharge at too high currents drying them out. I would be wanting to know the size of t...

I now have the ESR meter and Howards 4 caps They measure close to 2700uF on my capacitance meter and between 0.026 to 0.024 ohms on the ESR meter. Now the question is are they really 3300uF very strange they all measure very close to 2700uF , my meter is home made but is accurate. Will be interestin...

I have a ESR meter on the way. I will measure the various caps and see what the results are. Note it can measure at 100kHz Looking at two cases of smoking caps high current is involved.

I still think they need more cooling the fans were slowed down too much, my units (the older ones with external black heatsink) get to over 50C on the inverter heatsink inside the units, so I have external temperature controlled fans to keep it below 40C

I tried the induction unit today- It is not harmonics causing a problem its the on/off switching of the load the PIP has to try and keep the voltage at 230v with a load that is going on & off so it goes over/under voltage while trying to keep up.
