I have axpert king 3.2kw inverter, it starts normal but upon 500watt load it shows fault code 52.i replace the bus side IGBTs with new ones but shows the same fault.any body please how to solve this? So fault code 52 is "bus voltage too low". I suggest the next step is to measure the bus voltage, a...

I've read newer imiev's have an extra small electronic module mounted on top of the charger, which might act as a go between for the EVSE and the chargers CAN bus. I wonder if it might be possible to order a part from Mitsubishi and retro fit that? You'd still need the Gelco wiring harness with all...

Should/could this topic be moved to “charging infrastructure”

Done.

Perhaps this topic could be moved from “the lounge” to “charging infrastructure” group ?

Done.

What about the two battery voltages PBCV and PSDV? Is the battery voltage always tested against both voltages? The battery voltage is always compared to the higher value of the back to utility (PBCV) voltage setting, or the battery low voltage (battery low cutoff setting (PSDV) plus 2.0 V (0.5 V fo...

I just found out that I can set decimal PBCV (Battery voltage back to utility) values: Huh, well spotted! The manual says the value should be an integer between 44 and 51. I'm not sure if the value will really be tested for if it is not an integer. It's not actually tested for integer-ness, at leas...

Connection G-12 as I read the circuit connects a grey wire from the pilot pin on the charger inlet socket to a blue wire to pin 9 on the E-03 connector at the back of the charger/DC-DC converter. Yes. I expanded the image back in this post to highlight that connection in red (upper red connection),...

What could potentially, worse case, happen if tied the neutrals in terms of safety while relay is shorted ? All I can think of is something like this. Your neutral connection to the grid goes high resistance, and you have a non-inverter load running (oven, hot water system, etc). That brings all th...

I have the floating AC output issue where half the voltage is on the neutral when running off batteries. Linked to the above is the RCD issue on AC in. With no earth bond, the (incomer) rcd is happy. If I have the ac out N-E bond in place, the moment the inverter switches over to bypass, the (incom...

Where did you see "MK2"? I've not seen it. I would say it's the same thing. On the sticker on the side with the serial number. Model Name: RCT-AXMK2-5K-48V. It could just be that RCT slightly altered their part number on their batch? It's not clear to me. Does your model have the round bottom to th...

I eventually got it to talk to my iMiEV. Cool! There are areas where it brings up an error saying the car is not connected or other reasons. Did you disconnect the diode [ edit: and resistor ] from the aftermarket harness? That should be provided only by the charger itself now, via the equivalent o...

Is it possible to parallel an Axpert 5K (145V SCC) with an Axpert MK2 5K (450V SCC)? It's a tricky question. I found this on the forum: "** Firmware version 71.71... I've updated that today to include some more recent firmware version numbers. Sorry for not keeping that page up to date. Is the MKS ...

Welcome to the forum. Do you think that it is possible to modify the firmware of the 5048MS to send via rs232 the remaining available PV power. No. The only real way to discover how much power is available is to pull as much power as possible, and note what that value is. If you happen to have a ful...

It seems that the fan speed control output from the control board is on pin 40 (FAN SPEED/). I've trace pin 40 and it leads to an IC labelled U18 but not much after that. Ah. You seem to have a Growatt inverter-charger, which bears remarkable similarities to an Axpert, but is far from a copy. I hav...

Please tell me what do you think about chinese MOSFETs and IGBT parts for my inverter... Sorry, I've never bought power semiconductors from Ebay. I once bought an unusual IC for an EV charger that I could not find anywhere else, and it seemed to work OK. Personally, I would buy from Farnell/Mouser/...

I am not sure about its condition, I don't see any visual problems on those IGBTs but when I am measuring E-C and C-E on diode attribute then on QB2 and QD2 I've got 0.0V in both directions, That's definitely not OK. The two 2's (QB2 and QD2) form one half-bridge; they will be shorting the DC bus. ...

so if i live off grid i also can't use these inverters? As long as all your loads are 230 V and don't have any 115 V loads or any expectation of balanced voltages with respect to earth (called ground where you are?), it may be possible to use an inverter designed for line and neutral in your situat...

Hi, can somebody tell me if i can use the automatic transfer switch in the PIP 5048 230VAC if i have 2X 230 line supply. I mean L1 and L2 without neutral wire. between wires i have 230V, from L1 to earth 115V, and L2 to earth also 115V I don't think you can do it safely, because there is no way of ...

It seems like very good value for money, if it really does have a new battery, and of course depending on condition.

Odd that they don't show a photo of the actual car.

Will the values be written to the EEPROM every time it's changed?

Yes, but the effect on lifetime is minimal, as per this post.

Is there any way to make it exit this funk as you suggest below using setting changes over RS232/USB? Once the dip has started, I'd say there is no chance to exit it with a command. The SCC is resetting, and/or the controller is in zero charge state. So this can actually be fixed by issuing command...

........... And yes, it WORKED !!!! Now I've sniffed all communication so I can try to write a better flasher software. Martino.Q , well done! https://forums.aeva.asn.au/download/file.php?id=2450 I just noticed: unless your inverter is different to mine, or your local wiring colour code is differen...

Edit: have not figured out yet how to post a document or image... I have a post about that here . BTW, I meant to say that since you have all 5 pins in your J1772 inlet, and you have a 2015 charger, you definitely should be able to get the pilot signal control. It's a matter of what mods were done ...

Could the mod be to add a connection from pin 3 (assuming it's pilot pin on the inlet socket [G-03]) to pin 2 of [G-12] that connects to pin 9 of connector [E-03] respective to pin 5 of [CN-101].** I assume you mean would the change required to achieve pilot signal control be to add the connection ...

Sadly I now think it may be impossible or very difficult to modify my car so it can use a variable or reduced Amp EVSE. Yes, it looks that way, unless you can find a cheap 2011 or later charger/DC-DC unit. [ Edit: I realised later that you already have an updated charger, yet it's still not honouri...
