Re: Modified PIP-4048MS and PIP-5048MS firmware with Dynamic Charge Current Control

I would need to send a MNCHGC0### command at least once a minute (otherwise it will stop charging)? Yes. It will behave as if an MNCHGC0500 command has been sent, setting the current limit to zero, except that the clock icon will appear next to the flashing dot. There will be no relay clicks or EEP...

Re: Tesla PW2

What is the bus voltage to where the solar panels feed to? I'm only familiar with the Voltronic Power inverter-chargers. There are two different Solar Charge Controllers (SCCs) that come with these. In the PIP-5048MS and similar, there is a buck converter that takes the 60-130 V panel voltage and b...

Re: Making a conversion J1772 / IEC 62196 capable

I wonder if the AVC2 is a bit too simple for the average charge point? Surely the whole idea is to be completely compatible. Maybe it's timing of one of the resistor changes, so the AVC2 should work with most EVSEs that aren't too picky. Jeff Owen has posted about some EVSEs needing proper timing, ...

Re: Solar day parking with AC charging

Utilise a signal on the grid, similar to off peak, that signals ev charge points to turn on when there is excess feed in. I like that idea. And it could even use the same signal that is already deployed widely to turn on loads as needed, just that those loads were usually at night, and usually wate...

That won't be too much current, under 40 A, but it might be a bit weaker than 3S2P in shady conditions. I'd say it's your best option.

This 3 phase inverter is 10kW, is that a 3333w per phase limit, or can it shift output from one phase to another as required to a max of 10kW? It's 3.33 kW per phase, so no one phase can be transferring more than 3.33 kW at any one time (with allowance for short term overloads). However, within tho...

For a Leaf, I assume that 3 phase charging is overkill though seems not much in it for pricing. Three phase or not would be decided by (1) if you car can use three phase (I assume that Leaf 2.0 can as it uses type 2 connectors, earlier models can not as they use the J1772 type 1 connector), and (2)...

Re: 3 phase outlet, what is suitable for EV charging?

22 kW is 32 A per phase (230 x 3 x 32 = 22,080). And 240 volts X 1.732 (square root of 3 (phases) ) = 415 volts Sure, 415 V phase to phase. But with 3-phase loads, either the voltage or current gets split such that the load only sees 1/√3 times that voltage or current. So either the 415 V is split ...
