PIP-4048MS inverter

As a quick fix maybe http://www.lowenergydevelopments.com.au ... -Regulator
Check with them that it does not go above 60volts when it charging
After looking at the instruction sheet it seems you can set the max charge voltage so this unit should work OK

PIP-4048MS inverter

Here is some of my observations over the last 12months I put a temp controller onto one of my units to watch the temp and the heat sink was at 50deg C so as I had a few 48v 125mm fans I screwed one each side of the unit at the top over the air inlet and set the controller to come on at 42deg and off...

PIP-4048MS inverter

Firmware 52.30 compared to the older one that had the fans running flat out under a light load Note I have a number of inverters have not updated any firmware just have one with the older version before 52.30

PIP-4048MS inverter

I now have a temperature probe in the fins of the 230v inverter it gets to 48c with a light load of 300watts I think they may have gone too far with the fan slow down.

Re: PIP inverter repairs and hardware modifications

I have a question for those that have taken their units apart and looked closely at the circuit and components as I still have warranty I have not completely pulled my ones appart. Other than the 63V capacitors is there any reason it could not go to 62volts ? I know its firmware will not but what ab...

When you loaded the new firmware exactly how was your inverter set up I want to update my ones.

PIP-4048MS inverter

Looking through the posts I do not see mention of M.E.N http://www.eece.uwa.edu.au/students/safety/elec3307/earthing-cpd I just wonder if those with these units have paid attention to this. Here we have an example of what can be required as the relay switching in the units leaves the neutral floatin...

Re: PIP inverter repairs and hardware modifications

It looks like a different MPPT unit I wonder if the older ones are capable of much higher currents. All the rest looks the same. You sill have not said what type of battery, is it lead acid or something else. The two caps that have gone would be across the battery and at 63volts I think there is a n...

Re: PIP inverter repairs and hardware modifications

My ones are the units with the heat sinks on the top but only get warm even at 60amps they are MPPT units.

Re: PIP inverter repairs and hardware modifications

My unit is not getting hot at all even with 60amps of solar so the heat sink has to be overkill.

PIP-4048MS inverter

Keep away from those USB to serial cables when up loading to a micro controller. Your symptoms are the cable dropping in and out of the system. Try and find a computer with a real serial port, should be able to get one for free with XP on it. I write software for Atmel AVRs on a windows 8 system and...

PIP-4048MS inverter

I have been following this for number of months. I have two systems running one has 12 x 240w panels 225AH battery T105s the other at present 20 x 240w panels 1000AH VRLA this one is not finished as its only running with one inverter but will eventually have two and 24 panels. I have months of data ...
