Re: PIP inverter repairs and hardware modifications

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...

Re: 2010 Imiev charging question

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...

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

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...

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

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...

Re: Conversol A9 3KW 24v

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...

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...

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

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...

Re: PIP inverter repairs and hardware modifications

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...

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. ...

Re: PV dips and freezes

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...
