I assume that the KettleKomp™ voltage is tested against PBCV and raw battery voltage against PSDV. Am I right?
No. All comparisons related to either low cutoff voltage (PBCV) or back-to-utility voltage (PSDV) use the compensated battery voltage. That includes the low battery warning that appears below the low cutoff voltage plus 0.5 V, and goes away above the low cutoff voltage plus 1.0 V.

Hi. I'm having trouble to connect with my inverter with the com board. I used pin 1 and 2 for tx and rx and 8 for ground. But it doesn't want to connect via a USB RS232 adaptor. What is the problem to connect it straight to the 6 pins connector on the board? Why is the opto coupler so important? I bought the inverter second hand and there was no cable and that's the reason i have to fiddle around. What could happen if i connect it straight to the white connector?
Thanks for help

I assume you've made a cable from the pin-out in this post.

It's not clear to me, but I believe that the power supply common ("digital earth") is essentially connected to the negative end of the DC bus. This alternately connects to neutral or active of the inverter output, depending on whether the output is active-positive (one half cycle) or active-negative (the other half cycle), respectively. So for 10 ms it is at neutral potential (a few volts AC with respect to earth, depending on wiring and loads), and for 10 ms it is a negative half-cycle of 230 VAC.

In short, I believe you'd fry your interface, possibly also your computer, and there is a chance of shock and/or fire. Plus, the signal would not get through. But that's about it :shock:

This is what makes the PV input connections on the 450 V and 500 V max PV input models lethal, even at night. It also seems to be the cause of a bus over-voltage problem when there is leakage to earth from wet solar panels in the PIP-5048MG / Axpert MKS II models, resulting in fault code 08. It seems that the voltage from the negative end of the DC bus (where you want to connect, in effect), is getting rectified and fed into the bus capacitors.

So you absolutely need the opto-couplers; either those on the communications board or your own. But it seems to me that you may as well use the ones on the communications board.

Lots of people have trouble connecting to the comm port at first; read through the relevant posts and eliminate all potential problems.
For example, is your USB to serial adapter one that uses the known-compatible PL2303 chip?
Can you see your commands coming through on the PIP's RXD pin (pin 2 of the 8-pin RJ-45 connector)?

Hi to everyone here.
I 'm new here in this blog, neverlless, I have checked already all what was written about the fault code 08 here .
This is probably question for one of the members with similar problem or maybe for Coulomb directly.

What is the problem: I have ORVALDI MKS5K MPPT 3000W, 48V, 4/5kVA, installed originally back in year 2014, with lead acid battery's 48V system- 180Ah, solar panels on roof 3,6 kWpp. All operated by line or from solar/batterys. All was OK until in year 2017 when I have problems with the TX6, D62 and souroundings on main board, only solution then was to change complete main board in July 2017 and since then up to 1 month ago, all works as need to.
Then sporadically starts to happened fault 08, which could only be reset by hard reset (battery off) and after restart it works OK until to another fault 08.
Mainly fault comes out, when in the morning between 8-9 AM at very high sun in this days, battery charge reach 52,0V (setup in parameter) and when unit want to change the supply of house loads from line supply to battery/solar supply.
Fault 08 comes out very sporadically, one or two - three days with no fault and then (especially on days with strong sun already in the early morning) happened last days every day.
Just today I have encountered, what really happened in that moment: when battery voltage reach 53,9 or 54,0 V and charge step up to upper charge setup of 58,0V , suddenly starts to charge the battery's with very high current (setup max is to 60A) - at that moment it could be heard the bubbles in the battery's. Of coarse (thank's good) the fault 08 comes out imidiatelly (otherwise probably the battery would explode).
After restart (hard reset) unit works like never has nothing happened, but it is busy to do that all and all again.

So on first view, mine problem is not like any similar what's already described here in this forum happening around fault 08.

Just for info: PIP operates still with original software version U1= 52.20 and U2=01.24 ( I was not upgrade it when it was not needed at all, when all works ).

I still have old (original main board with missing TX 6 as upper described) and maybe somebody could help me to trace, where this battery charge control is located (is it on the main board or it is somewhere on the SCC or other boards).

My intention is to repair the unit in any case, first need to locate the electronics parts, after then would order possible problematic parts and then reassemble all needed when spare parts will be in hand.
Otherwise I' m dealing with hobby electronics and have all needed instrumentation and parts around, but anyway

Please help if possible

Many thanks in advance

Yes. Though you should first check that your present firmware is version 74.XX.

I just upgraded my old PIP4048MS (purchased September 2015) with a Victron Energy MultiPlus II Inverter Charger 48 5000 70-50 IP21.
The SCC in my PIP4048MS smoked itself about a year ago and MppSolar will not supply me with a new SCC as the inverter is too old. ... 2749.l2649. I was amazed how compatible the connections are. Also needed a seperate Smart MPPT solar charger. This inverter can export power to the grid or it can just be setup as an off-grid inverter. And this inverter is actually designed for lithium batteries. Weighs a ton (29kg) compared to the old PIP4048MS. Built in India and designed in the Netherlands this inverter feels like quality. And this inverter is CEC approved which means you can get solar panels installed by a CEC Accredited solar installer and the cost of the solar panels will mostly be covered by STCs (government rebate - Australia only).
Below is my CCGX monitor setup in my kitchen.
Below is a picture of my VRM portal. Everything can be viewed or settings can be changed over the internet anywhere in the world where you can get a WIFI connection.
I am posting this for anyone who is looking or considering buying a better designed inverter and is willing to spend more then this is a good replacement.

The victron units are good inverters but the cost difference is enormous if I had used their inverter then purchased all the MPPT chargers needed that are part of the mpp solar units it would have cost me 4 times as much if they brought the price down and made them competitive they would sell a lot more. As a person who could design and build an inverter I do not see the extra cost in them, for a commercial installation I can see them and similar units installed due to warranty etc.

For those that need a COM port number changed to allow a flash update to an inverter firmware, here is a step by step guide for Windows 10.

Before you start this, make sure that the problem isn't that Watchpower is still running in the background. Merely closing the GUI window doesn't stop the background task, which keeps the COM port in use. You have to exit using the system tray, as per the firmware upload instructions. This is probably the most common problem preventing a reflash. The symptom is that the COM port for your USB to serial adapter doesn't appear in the Ports drop-down box on the reflash tool. Other monitoring software that runs on your PC probably also keeps the COM port in use as well. ICC usually runs on a Raspberry Pi, so that won't be a problem, unless you are running a very old copy of ICC for Windows.

Step one is to run device manager. I just start typing the name in the "Type here to search" box at the bottom of my Windows 10 machine. Windows 10 can be configured many different ways, so use whatever method you need to run device manager. It's part of the system, it should always be there. It will look like this:

Look for the Ports section (highlighted in blue above). Click it to show your current ports. Note that if you have nothing plugged into a port, it won't appear in the list of active ports. If your USB to serial adapter doesn't appear, check that it is working, plugged in properly, and that the USB port is working (try some others if necessary). Here is my list:

Redefine com port 2.png

Your USB to serial adapter will probably have a similar, perhaps not identical name. Double click on that entry to bring up the main dialog box for COM ports:

Redefine com port 3.png
Redefine com port 3.png (39.5 KiB) Viewed 45 times
It will probably open in the General tab. We want the Port Settings tab (highlighted in blue). Click on that:

Redefine com port 4.png

Click on the Advanced button:

Click on the Com Port Number drop-down list box:

Redefine com port 6.png
Redefine com port 6.png (55.73 KiB) Viewed 45 times
You may have to scroll up to see the early port numbers, as I have above (use the button outlined in orange). Note how several of them are marked as in use; avoid those (though I suspect you could force them at a pinch). I'll choose COM port 2; COM port 1 if available might be a better choice for those rare occasions where you need to update the SCC firmware on a PIP-MS (Axpert MKS) machine. The reflash loader for those is different to the others, and insists on using only COM port 1. If you need COM port 1 and it is in use, you can temporarily redefine that port to some other number, then move the USB to serial COM port to COM1. With the desired port (COM1-9) highlighted, press OK. That's it. Just close all the device manager dialog boxes by pressing OK.

If you have an earlier version of Windows, and following the above doesn't work, you might be able to find instructions like these inside one of your update .zip files; these are often for older versions of windows.
