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 ...

Re: PIP-4048MS

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-4048MS inverter

Well sleuthed! Maybe an optic fibre camera next? 😎 http://www.tejota.net/media/k2/images/Solar/Inversores/5048PF164V/Mosfet.jpg Is there a special firmware revision number? I imagine they would want to distinguish the high voltage versions from others, yet indicate what other features and/or bug fi...

Re: PIP-4048MS inverter

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...

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...

PIP-4048MS inverter

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. New type scc cannot be easily connected to old type main pcb. Do you talk about different comm board?? I think com...

PIP-4048MS inverter

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?
