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

Tejota Have you tried each inverter on its own not connected as parallel ? I dont understand what you say. I have changed parallel boards and can wires. Error 80 goes on. Then, problem is inside inverters. Hardware o Software?? I have noticed that error 80 goes when hot conditions are present (Temp...

Perhaps a board parallel is faulting ?
Yes. Or it could be a CAN cable.
WTF... But which one? I think fault board throw error 80 the first, after the others?? Is it correct?

CAN cable is very difficult to fault.

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

Restart units solves problem but why happen? Have you checked the current sharing cables? (The wire pairs that terminate in small green plugs). These have been known to work loose (or were loose from the start but only played up long after installation), and have caused this error in the past. Anot...

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

Hi folks...

A question? What means error 72 on parallel setup ? Manual says : current sharing fault

Restart units solves problem but why happen? parallel setup has got few watts on load when error 72 started, about 100 Watts per unit more less.

Regards.

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

Model type: stand alone !!!!!

You have to put in parallel mode. Be careful if join AC OUTPUT of two PIPs without parallel card and parallel setup.

Re: PIP-4048MS inverter

It's true that for models that came with firmware before 73.00, there is no connection from inverter neutral output to earth under any conditions. However, in the models that come with 73.00, there is a new changeover relay that connects the inverter neutral either to earth when in battery mode, or...

Re: PIP-4048MS inverter

Weber and I have finally finished testing our patched firmware based on factory firmware version 73.00. Hardware that comes with factory firmware 73.00 has a neutral to earth relay, which is active only when the inverter is in battery mode. I noticed that neutral to earth relay is active only when ...

I assume that the slaves would have been Axpert 4 048s, being 4 years old now. Yes, the same as pip4048 old version, heatsink on top. Manufactured on Mars 2014 but in service from December 2016 (one year and two months working ). PIP4048 new version without heatsing on top (master) was working with...

Re: PIP inverter repairs and hardware modifications

There is a special-order model of the PIP-4048 that allows up to 64 V of charging, I assume it has different MOSFETs and higher voltage capacitors, and different firmware. MOSFETS in PF1 5kW up to 64V charging are TK100E08N1 I have seen them through the grid of holes. I dont know if there are 16 or...

@TonyB Has this invertert got both usb and serial connector ?? I have got 3 of them (same model but only serial connector) in parallel with pip4048ms and I could flash firmware without problems. I used this cable And laptop with W7 32bits. No problem with flash both firmwares (72,60b and 4.10). My i...

PIP-4048MS inverter

32 param is bulk charging time. Options: Automatic (default) or time (5-900 minutes) Tejota, I'm interested in how parameter/setting 32 is supposed to work. My reading of the firmware is that it is intended to be a *maximum* absorb time. So if you set 20 minutes, the absorb phase could last for any...

PIP-4048MS inverter

What does automatic do The same as previous firmwares. 32 param is only setup if param 5 is in USE mode. Time in 32 param is to equalization batt. If you want to equalizer batt bank manually you can set up param 5 to USE, param 26 to equal voltage and param 32 to time to equal voltage. Of course pa...

Old type scc can be connected to new type main pcb. New type scc can be connected to new type main pcb if the spade connectors of one inductor are removed and joined to 2 longer wires.

Re: PIP inverter repairs and hardware modifications

after looking at your photos again Thanks for the photos, they're very helpful. That black box is a relay ( see here ) and it looks to me like they're routing it out to the RJ45 on pins 3,4,5 although it's difficult to see clearly with all the silkscreen. http://forums.aeva.asn.au/uploads/3980/2013...

PIP-4048MS inverter

Problem solved: Param 29 is not configurable when you put AGM in param 5. Ah yes. Well found. Params 26 and 27 (absorb and float voltages) aren't configurable then either. The same occurs when you put Fld in param 5. Would you change to USE mode instead AGM mode? Yes. But you must then make sure yo...

PIP-4048MS inverter

Problem solved: Param 29 is not configurable when you put AGM in param 5.

Why? I dont know.

If you put AGM in param 5, param 29 is automatically configured at 42V.

All of that occurs on every firmware (52.11 to 72.60A)

Would you change to USE mode instead AGM mode?
