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

do you see any issue with the battery if its already charged up and still receiving 55.2V Once it's fully charged, then leaving it at 55.2 V is just going to slightly shorten its life, while not providing any more energy. You talk as though it doesn't start the day in the bulk charge stage. If that...

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

I have added 2 pictures to explain this, at high voltage of over 190v I was basically not generating anything (no mppt) ... Actually, I didn't realise at first (the second post is rather blurry), but the icon that is missing isn't the MPPT, it's the battery . So perhaps by 5pm your problem is overc...

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

Hi, first time posting Welcome to the forum. And thanks for providing details of your setup first thing; it really helps. I have set them up with 56V as Bulk and 54.2V as float. Those are possibly a tiny bit high for the longest life. Weber and I also use 16S LFP, and we use 55.2 V and 53.8 V. But ...

Re: Prelude conversion project - some questions

Re: PIP-5048MK inverter

... I found that mine was actually built in November 2018! so the BMS port didn't function! Even worse, if the inverter is a 24 V model, it won't talk to the battery anyway, no matter how recent! I think that perhaps the 48 V model has an extra processor compared to the 24 V model, and the Pylontec...

Re: PIP-5048MK inverter

Well I do not know if inverter measure that load side right. I don't know the PIP-5048MK / Axpert King very well, but it's a fair guess that it uses the same current transformer to measure the load that the other models do. It seems to be pretty accurate and reliable. Similarly, the LEM seems to me...

Re: Idle and Load consumption - PIP 3024GK

It consumes (wastes) more power when the inverter is powering a load, but then it's not idle, so it's not idle consumption. Most of the PIP series have about 93% efficiency on the inverters, excluding idle consumption. So about 7% of the load power is wasted as heat. So for every kilowatt of load, s...

Re: Thunderstruck charger. Time for fun

if it will do type 2 or stuck with type 1 .. It looks like a type 1 (J1772) setup, as is common in the USA with their single phase preference. But all you probably need is a cable like this one to adapt a type 2 EVSE to what I presume will be your type 1 socket: https://www.aliexpress.com/item/3272...

Hack it.
But @Jeff Owen tells me that if I do that, there is a chance that some type 2 sockets won't engage fully, and will either be loose or perhaps won't allow charging.

Can someone speak from experience: will a shortened type 2 socket work with the vast majority of type 2 EVSEs?
