PIP-4048MS inverter

The parameter settings have to be done with the two AC outputs still separated. Did you check on the LCD that the settings you made from the computer had stuck, before paralleling the AC outputs? I had a look at a YouTube movie. After making the program changes to parallel they had to cycle the pow...

PIP-4048MS inverter

It seems I wasn't clear enough in my previous long message re the standards the PIP must meet. There seem to be a number of misunderstandings I will try to clear up here. 2. I know of no reason why the PIP's AC input cannot be connected to the grid. I gave links to the manufacturer's test certifica...

PIP-4048MS inverter

Thanks Webber, The way I see it I can use my PIP-4048MS inverter in a stand alone power system to charge my PIP (plug-in-Prius). But it would be nice if this inverter became CEC certified so I could then connect it to the grid legally and then it would be OK with Endeavour Energy and claim STCs http...

PIP-4048MS inverter

Hi Weber, The Australian Standard for Stand Alone Power Systems require the PCE or our PIP-4048MS to have isolation/separation between the DC input and the AC output. Since according to the WatchPower PC monitoring program the PIP-4048MS is transformerless. Do you know how the PIP-4048MS achieves is...

PIP-4048MS inverter

I don't understand why anyone would take much notice of this graph when we have no idea of its source, which clearly isn't a peer-reviewed journal. And nor do we have a description of the experimental protocol or any explanation of what it means by "recovered" or why it should be accurate after ext...

Thanks lopezjm2001. Can you link the full article that came from?

It comes from a datasheet. I am not at liberty to say which specific Lifepo4 cell. Just to say that one Lifepo4 cell is the same as the next.

PIP-4048MS inverter

I'm not sure if the cells being charged is the issue. My understanding is just having the cell stored at a elevated temp results in shorted life regardless of then being charged or discharged. I understand charging the cells increases the temp. Though very little at the rate we are charging them at...

PIP-4048MS inverter

Hi Weber, Simply because my BMS (brand is miniBMS) does not have serial comms. The other reason is that at the moment the unit is losing and restoring communications between my PC and PIP4048MS, I would not want a HVC event occur whilst it keeps charging/cooking my Lifepo4 cells because it lost comm...

PIP-4048MS inverter

I just got a reply from Maximum Solar: Hi John thanks for your feedback. that's right as you already know the challenge is that inverters run on DC so disconnecting battery will inevitably trigger a fault and possibly lead to shut down of inverter. I don't know how difficult it is to implement the f...

PIP-4048MS inverter

Hello All, I have just joined this forum after reading this great thread. I bought this PIP4048MS two weeks ago and have asked Maximum Solar the following. Dear maximum_solar, You need to improve the design of this item to be used with Lifepo4. To function properly with Lifepo4 battery bank the inve...
