Re: PIP-4048MS and PIP-5048MS inverters

Hello erland82 You could turn the inverter on/off with switch when you get there but the MPPT stops as well Best would be to keep your 4860 MPPT working. For heating before you get there why not use a 48V heater it can easily made A length of zinc coated steel wire wound into a long spring like coil...

Re: PIP-4048MS and PIP-5048MS inverters

Hello erland82 Remote monitoring is easy to do by using a RS232 to TCPIP HLK RM04 module no programming knowledge required they are ready built just need a box and 5volts I use them for my two systems that are 250Km apart so I can monitor both from either location , settings can also be changed. Wou...

Re: PIP-4048MS and PIP-5048MS inverters

"that respectively force an inverter into standby mode"
Can units in parallel be shut down say one of a pair.
What happens with paralleled units if the load goes up will the standbys come back on?

Re: PIP-4048MS and PIP-5048MS inverters

I think you may have misunderstood it was not a 240V ups I had, for over 15 years a 48v DC system
and I still have it running 48v to 12v for various gear and some that runs straight off 48v.

Re: PIP-4048MS and PIP-5048MS inverters

Actually 6 inverters 2 spares got them early at a good price. Big battery bank second hand 2nd home battery bank was new but it replaced a previous 48v ups before I thought about getting solar so not ideal. If I just wanted to reduce power bills I could have just got grid solar installed but there i...

Re: PIP-4048MS and PIP-5048MS inverters

I have my ones two homes , four inverters mounted on ply wood I do not see a big risk of fire
They could be mounted with fiber cement board behind them which has a good fire rating
If mounted on a metal surface earthing and insulation need to be considered

Re: PIP-4048MS and PIP-5048MS inverters

I also found on my units the heat sinks were getting to 50c and above which does not fair well for long life from the transistors and more so for the capacitors my solution was two 120mm fans over the vent holes at the sides controlled by a ST-1000 controller with its probe in the inverter heat sink...

Re: PIP-4048MS and PIP-5048MS inverters

I have AC voltage and current meters on the input and output of the inverters so far all are 3 volts out just wondered if this was a common thing since I know its not a problem if it had been a simple fix I would have tried to do it but will just live with it. The only thing that bugs me is not havi...

Re: PIP-4048MS and PIP-5048MS inverters

My inverters read the AC voltages 3 volts higher than actual as its all of them (6) has anybody checked to see if they have the same
and can this be changed to be accurate?

I have all my panels as strings of three tested at two's it worked but only with good sun little cloud
went to strings of three my max voltage has been 119v and it works much better with cloud

Re: PIP-4048MS inverter

Seems like they have implemented most of the recommendations I sent them , just need plug in connections for the battery and AC so replacement of units is not a major task. Note if you send recommendations to them make certain it comes with hard data eg flooded lead acid needing 62V for equalization...

Re: PIP-4048MS inverter

Yes with two you get double everything so you could charge at 120amps.
Note both units charge amps are set interdependently solar and grid/generator.
Yes the price of the other brands is eye watering even after buying spare inverters (which is what I did) you still have change.

Re: PIP-4048MS inverter

Replacing a failed 4048 in a parallel set is a problem people will increasingly be facing. I do not have a solution. My solution was to have a spare infact I have two, one for each location. When you consider the difference in cost compared to say a victron unit a full set of spares is still cheaper!

Re: PIP-4048MS inverter

I would look into warranty return before opening.
Note I had more panels on one unit at one point but it maxed out at 61amps even though more power was available so it should not have overloaded.

No its not windows or linux its all written by me its a 64k AVR and it just sends what it gets on serial one to serial two which puts it onto the terminal on my PC and I have given it a 256 byte buffer so I increase that too see. It also does the CRC and will print crcbad to the lcd so I know. I gav...

So the idea is that if you accidentally connect the battery in reverse, nothing blows up, and there is no great splat. In later models, they must have a large diode connected across the battery
Or maybe a fet and diode

Re: PIP-4048MS inverter

My batteries are mine cadmium nickel with KOH electrolyte 48 cell x 150Ah They will need a different charging process to the lead acid I do not think the inverters will do it correctly see below: Charging Flooded Nickel-cadmium Batteries. Flooded NiCd is charged with a constant voltage to about 1.5...

Re: PIP-4048MS inverter

I have two 1Hp pumps running off my inverter but they do not have start capacitors only run capacitors more than a year 4 times a day no problems.

Now an update on LCD remote control:
I have the infrared remote working and any old remote can be used it learns the buttons.

Re: PIP-4048MS inverter

Now the display of the second parallel inverter with the QPGSn command
Image


So that is two of the commands now to get the rest working and to enable changes to settings with infrared remote control.
