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?

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

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

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

Re: PIP-4048MS inverter

I have a number of AC voltage protection varistors here I am thinking I might put a bunch on the AC downstream of the inverters. I think we need to keep the semiconductors and capacitors cool in the pips so fitting 120mm fans to the grills at the sides and inserting the temperature probe of one of t...

I have 72.70 running on the systems and the battery performance appears to be much better but note I also have the 9 panels with the e-smart3 as well. The battery is staying at a higher voltage for much longer while under discharge at night, the balance of the current from/to the banks is much bette...

Re: PIP-4048MS inverter

Have a problem with 72.70 the Max. Charging Current setting has become a max current setting for solar charger so if you set it at 30amps that is all the solar charger will put out instead of being max charge to battery. Only found this out because I loaded them up to 4500watts and was getting a bat...

Re: PIP-4048MS inverter

Please note on the RJ45 of the inverter there is a +15 volt power output to drive the remote control unit this is provided by a small transformer on the comms board which also provides this 15 volts to the RS232 so be careful not to short this out. I run the HLKRM04 RS232 to TCPIP converters from th...

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?
