Re: Climate control mod to turn off heater

out of curoisity, does the car throw an error code if you physically disconnect the heater element? It would seem so. From the Method 1 post: "Caution: You should avoid leaving the connection open or shorted out while the car is turned on. This will cause NO damage but it will log an error (DTC cod...

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

What do you recommend as an appropriate battery settings for a VRLA 24v battery set-up because I feel that "back to battery" at 27v may be too low? Settings 12 and 13 are about "rescuing" the battery when it gets quite low in SOC. So setting 13 is supposed to be when the battery is back from that s...

Climate control mod to turn off heater

One of the niggles with the early Leafs is there is no separate button to turn off the heater. So it's a hassle to just get the fan circulating air, without using main battery energy to produce heat (and it's a resistive heater, not a heat pump, in the early models). Weber kindly pointed me to this ...

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

My GK series has a settings called battery discharge voltage, mine is at 27v and I have noticed that the inverter will switch to battery once it gets to 27v. Is this a normal behaviour? What is the setting number or abbreviation? It it's setting 13, this is usually called the "back to battery" volt...

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

From the above are you suggesting that equalization should not be done with AGM/VRLA batteries? Pretty much. I can see some value in a very gentle equalisation, but just one or two tenths of a volt over the normal bulk/absorb voltage. You want to stay away from the gassing voltage of 14.4 x 4 = 57....

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-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...
