Re: PIP5048MG: 3Phase Configuration: Fault 08 and anomalies.

Hi dRdoS7 I'm thinking of having a Latronics ATS installed soon, that has a 12ms transfer time. Iv'e used a CHTCC device (single phase=ZHRV2-54T and 3-phase=ZHRV2-S45). These are quite handy little devices with a display - great for making a pseudo ATS. Lots of features and you can set over-voltage,...

Re: PIP5048MG: 3Phase Configuration: Fault 08 and anomalies.

Hi dRdoS7 Not sure if I want workaround to work, I'd rather have a fix. But I'll try that on my MG, but set it at 2A, and I'll use 10A if 2A doesn't work. It will charge the battery up to "back to battery" point, then discharge again, 10A is pretty much what our load is overnight. Trouble is, it onl...

Re: PIP5048MG: 3Phase Configuration: Fault 08 and anomalies.

Hi coulomb 3. On the 'faulty inverter", Change program #11 to 10A (Max utility charge), Change program #16 to CSO (Charge Source Priority) - only on the 'faulty inverter'. My theory was that if there is at least some demand on the bus it might keep the bus voltage regulated to some extent. That's an...

Re: PIP5048MG: 3Phase Configuration: Fault 08 and anomalies.

Hi coulomb dRdoS7 Ah. I wonder if you have a pesky load that you use rarely. One that has a half-wave rectifier in it for cheap and nasty low power operation, such as a hair dryer, heat gun, etc. Some of these also do cycle skipping, which can upset the control systems. One of these systems controls...

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)

Hi coulomb Any suggestions on how to get started with 'flashing'? Read the reflash instructions carefully. The most important thing is probably a USB to serial adapter that is likely to work; see the link to the post about the PL2303 chip. Read the last paragraph, re "bricking" the inverter. It's ra...

Re: PIP5048MG: 3Phase Configuration: Fault 08 and anomalies.

Thanks again coulomb As there is no PV at night and the loads are using utility (SOL) I am assuming the DC-DC converter creating the bus voltage is the one connected from battery to bus. If the battery voltage is high enough, yes. Otherwise, the free-wheeling diodes in the inverter may set the bus v...

Re: PIP5048MG: 3Phase Configuration: Fault 08 and anomalies.

Thanks weber You could try swapping inverters between phases, to see if the problem stays with the same phase or the same inverter. I'll see what happens over the next few nights and if fault 08 comes back I will move to another phase and see what happens. Good suggestion. coulomb The original poste...

Re: PIP5048MG: 3Phase Configuration: Fault 08 and anomalies.

Hi coulomb weber The "bus" is a pair of wires with roughly 400 V between them. It powers the inverter proper (the thing that generates 230 VAC), and is fed from either the PV boost converter, or the DC-DC converter connected to the battery. When the battery is charging, this battery DC-DC converter ...

However, we are in communication with a German forum user who may be able ...

Re: PIP5048MG - Earth and Battery

The 3-phase RCD is on the Utility 3-Phase input - then that branches to the Inverter AC Inputs - no more RCD's in the way. OK, but didn't you say you made the change to put the AC-ins of the inverters directly to the 3-phase breakers, i.e. before the 3-phase RCD? Erm no. We have a main Utility brea...

Re: PIP5048MG - Earth and Battery

So the RCD that trips is between the outputs of the three inverters and the loads? The 3-phase RCD is on the Utility 3-Phase input - then that branches to the Inverter AC Inputs - no more RCD's in the way. The RCD is there because there is a 3-phase machine attached to the Utility. There are also o...

Re: PIP5048MG - Earth and Battery

Hi coulomb RCDs on the AC-in are often nuisance triggered by the EMI neutral and active to earth capacitors. It's best not to have an RCD at the AC-in (connect the AC-in before any RCD). You want RCDs on the output, of course. This morning I moved the 3-phase AC Input circuits directly onto the inco...

Re: PIP5048MG - Earth and Battery

Thanks again coulomb Always valuable responses. So with the power off, all the relays are off, so the neutral and earth would be connected. Great - wish this was documented. When the load is cut off, that's a different relay (again, presuming similarity with the 5048MS). In line mode, the neutral ou...

PIP5048MG - Earth and Battery

Hi all, Question 1: When the 5048MG is totally switched off or disconnects load as a result of going below the battery Cut-Off (program #29) does the inverter connect Neutral and Earth?

U1 on the inverter is 71.70 - when I use WatchPower it gives me a CPU version of 72.90. With the 4048 I can see U1 and U2 on the inverter b...

Hi @coulomb
See also this post. I don't know what to make of it, but I don't have paralleled machines.
My PVA arrays are separate estates for each inverter - as instructed in the manual. A rather obscure instruction I must say.

Welcome to the forum. Many thanks for the welcome and the response coulomb Looking at the 72.20 firmware, I see that this is triggered when the battery power is less than (more negative than) -1200 W for 3 checks in a row (10 ms apart), or less than -2000 W instantaneously. So that's some serious r...
