We have a couple of 2424MSD here. Reason for swapping out the serial board is, that it is crap.
Oh. My misunderstanding then. Sorry.

I thought you could get the serial boards, and other spares, from MPPSolar.

Re: PIP-4048MS inverter

where can I order a serial/RS232 module for the inverter? We mention Jaycar for the serial to RS-232 board. However, see below. Mine has the USB-only board... Ah. As far as I know, no models that have the USB-only board can use the firmware (factory or patched) found on this site. I don't understan...

Re: PIP-4048MS inverter

any idea how can i stop this ? or, where to start ? If you have the ability to inject commands to the PIP, and since you are using patched firmware, I'd try this pair of commands: MNCHGC0500 <CRC><CR> MNCHGC0499 <CRC><CR> This sets the dynamic charge current to zero, then sets it back to the EEPROM...

Re: PIP-4048MS inverter

Hi , and thank you again for all the help , I have disconnected the panels , but the problem remains, Ok.

And measured with a multimeter , even with the pv switch off , i have that 46v there , By "there", do you mean at the PV input terminals? Is it possible that this is leakage across your PV switch?

Re: PIP-4048MS inverter

When you say it uses the battery current at a certain voltage, do you mean when the inverter is on it can guess the SOC because of the voltage at that load? No, it's all based on total battery current. What happens when the inverter isn't on, what current is it using then? Sorry, I forgot to mentio...

Re: PIP-4048MS inverter

Coulomb, do you know if your custom firmware would work on a 'POWER MPS-5K, Model: MPS 5K-48VDC'. It's difficult to know. These inverters are identical to the Axpert. As long as they are genuinely Voltronic Power made, it should work. Do you have a link to the Ebay advertisement? I could not find it.

Re: PIP-4048MS inverter

so in "bulk" mode you will see a rise to 56v and then it is in absorb. Yes. I guess the thing which seems weird to me is aren't the batteries full at ~52v for AGM . Battery terminal voltages are a bit weird. 52 V (13.0 V per 12 V module, or 2.167 V per 2 V cell) is indeed a good 100% SOC voltage, b...

but I saw in the last firmware update that I can set maximum charging from zero, is it not true? Sigh. I'd forgotten that patch; it's one of the earlier ones.

Re: PIP-4048MS inverter

But I have only 40Ah remaining cells Ah. So that's why you only want one unit charging. I believe that even with no solar connected, you still can't set the maximum total charge (setting) to less than 10 A, so they will still contribute towards the total maximum charge current for the system. This ...

Is there a way to disable battery charging for 4 pcs from 5 parallel connected inverters? Sure, don't connect solar to the four, and they won't charge. I don't know why you'd want to do this, however; why not spread the charging load? Charging current limits are separate for paralleled inverters. Y...

Re: PIP-4048MS inverter

Is it normal for the PIP to not have a float or bulk/absorb voltage ? No. It should be aiming for either float or absorb voltage, depending on the mode. Check the charge LED (middle, green LED) to see if it is not charging at all (dark), bulk/absorb (flashing), or at float (solid green). Shouldn't ...

Re: PIP-4048MS inverter

As far as I can see, this matches the "Charge termination conditions" you mention in your post. If using a timed absorb period rather than automatic absorb terminated by charge current I would prefer it if the absorb period was not terminated by charge current but by time alone. This is the origina...

Also worth noting. Both HRC fuses had blown. Has anyone had this experience? I'm assuming the pip developed a short?? It's not uncommon that when a PIP goes faulty, that it blows its MOSFETs, which fail shorted and present a short circuit across the battery. Surprisingly, this rarely results in bat...

it will still use solar but there is something else im going to do Solar insolation is about 1 kW/m² peak, and solar panels are roughly 20% efficient, so 200 W/m². So perhaps 400 W on a typical vehicle. Compare that with typically 20,000 W for highway cruising, 10 kW for low speed level driving, an...

In this forum, we obey the laws of physics! I'm afraid that "self charging" is going to provoke comments like this. Do you perhaps mean wireless charging?

The SCC firmware is showing as 00000.00 and PV volts=0 and PV watts=0 during the day. It's like the SCC is dead. Under these conditions, I don't think you can update the SCC firmware.
