Re: MPP SOLAR PIP-8048MAX

Wonder if they have corrected any of the bugs? I can confirm that the main premature float bug is still faithfully and firmly in place. They really believe in that thing. Or, introduced new ones. That's much harder to tell. On the one hand, any version one product tends to have more bugs. On the ot...

Re: PIP-5048MK inverter

So there is no way to make it work correctly without any additional controller?! No. The inverter has no way of knowing the real SOC, unless it talks to the battery's BMS. When it does, they didn't change the logic to respond to SOC instead of battery voltage, as the Growatts do. So an additional c...

Re: PIP-5048MK inverter

How can I configure the 5048MK so that it switches to utility once the battery is empty/below a certain SoC level? Using the voltage settings for switching between utility and battery mode does not work reliable. Presumably you've been using the back to utility setting (setting 12). I guess that wo...

Re: Hyundai NZ recalls 700 Kona EVs

I'm not sure if it's technically feasible, will have to do a bit of research on that, unless one of the other admins (@coulomb, @weber ?) happens to know off the top of their head.

Re: Chargers being turned off

It seems to me that the only difference between type 1 and 2 chargers is the shape of the plug and that Type 2 supports 3 phase. I've had a bit of time to read the article you linked to, and I'm starting to agree with you. The two values type 1 uses for the switch (150 and 480 ohms) seem to be care...

Re: Chargers being turned off

I have visited a lot of chargers in the NSW/ACT region since I bought the car last year, and have never come across an untethered charger. Admittedly the vast majority of chargers are Tesla ones, but chargepoint and others all seem to be tethered. Some of them have a cable provided, but the cable i...

Re: Chargers being turned off

The proximity pin seems to have the same function in the type 2 protocol. I modified my own Type 2 plug with a switch and resistor and it works very well in shutting down the charge current and releasing the security latch on the connector. Huh. I find a fixed resistor in my type 2 to type 1 adapte...

Re: DIY 51.2V 100Ah Solar Energy Storage Battery System - All Kits Included.

I don't like the output terminals (looks like battery current goes through the screw). [ Edit: and it looks like the terminal screws aren't copper or even brass, though they could be tin coated. ] Is that a 4 mm banana socket at the front of the terminals? It seems weird to have the presumed BMS all...

Yes. Only the control pins of the AC part are used. They probably don't even have holes for the phase pins, so you couldn't even plug in an AC type 2 plug.

Re: Chargers being turned off

I'd be interested to know whether the advice to not turn a charger off 'at the wall' applies when they are delivering lower current. For instance when my TC Charger is in its final charging stage, which takes quite a few hours but delivers very little current. The main problem is the energy in the ...
