PIP-4048MS inverter

Well that's a pain. Haven't powered up yet so don't know what it has. So I noticed some changes in the new board. Let's play: what's been removed and why? http://forums.aeva.asn.au/uploads/4186/rps20160916_212303.jpg Both appear to have been filtering of the 230v, one on the input and other on the o...

PIP-4048MS inverter

I'm about to receive a new main board. I assume it will have later firmware and will already have lifepo4 as an option? So I just need to update the scc firmware? Can I do that without the main board?

OK, so 10 days passed since I emailed mpp the diagnostics results. Fed up, I contacted the eBay seller of mpp (who I bought from). Within 2 hrs, I received an email from mpp saying I would be sent a new main board. Lucky I have grid. For someone off grid to be jerked around that long is unacceptable...

Of those who have had an MPP SOLAR product develop a fault, what was your experience with them? I have found them to be evasive and uncooperative. Back in January I noticed a little smoke, so I filled in one of their forms and supplied the extra information. No response. The inverter kept working so...

PIP-4048MS inverter

In our case dinner is done by 6pm. Breakfast 8am. So that's 14hrs. Over a 20 year period that's 3883kwh. At say 25c per kwh (actual cost of panels/inverter/battery) that's $970.90. Will buy you a new inverter. Or $48.55 per year. People here were discussing reducing the contactor current by 100ma. T...

That is interesting.

I used a fluke to measure. Confirmed it with another dmm. Puzzling. Has anyone tested power consumption with scc, comms board and display disconnected? I found on the PIP802HS current fell to 2.5A

PIP-4048MS inverter

So I was installing my lifepo4 cells, decided to measure the idle current for my PIP802HS (12v 800w). And got 2.8A at 13.4v. Didn't think much of it at first. Then I did the math in my head and alarm bells rang. The whole point of me having a separate 12v system was to reduce the draw on the batteri...

I happen to be familiar with these Omron relays; they are used in Elcon / TCCH EV chargers I mentioned the pip relays and when you said "these relays" it was safe to assume that we were still discussing the pip relays. But now it appears you have not addressed my point at all and used a different e...

PIP-4048MS inverter

My impression is that you are considering using a device with no DC rating, and arguing "what's the big difference anyway, at these voltage and current levels?" You are trying to theorize your way through a debate, while discouraging real world testing. I on the other hand have demonstrated by way ...

Overly dramatic and misleading. 1mm per volt is utter nonsense. If that were the case, one time when I forgot to switch off the pip before disconnecting the battery terminal it should have arced 56mm. But it didn't. In fact I recall very little light and sound when it happened. The speed of separati...

I had a look at coms board discussion but my board is different. Definitely no transformer on it.

Sorry, I don't recall being hostile. You asked "why not use this?" and I explained why. Because it's only a design, not a tangible product I can use.
