Re: Electric Car (EV) Home Charger - 32A - Options?
I recently bought an Ioniq and I'm very happy with it. I also bought the Delta home charger / EVSE to go along with it (purchased from Hyundai and it comes from JetCharge). After getting the EVSE installed on its own 32A circuit, I am only getting 4.5kW charge rate so I went back to the supplier an...

Re: PIP-4048MS and PIP-5048MS inverters
@weber PIP-5048MGX = Axpert MKS III See solarpower24.it And don't forget PIP-8048MAX The MAX series are very much like the MGX. They both have the new feature to program timer settings for Output Source Priority and Charger Source Priority Thanks for those. I already had the PIP-8048MAX in the spre...

Re: MKS-II-5KWB Repair Please help
... I think even if you install new inverters the cause of this failure may still be there, I feel it could be a voltage spike on the incoming grid/generator to the inverters and with that blue capacitor (but is it a capacitor maybe its a MOV so can we have a picture of them with the writing on the...

Re: MKS-II-5KWB Repair Please help
So I managed to contact with MPP solar & Voltronic and it looks like the new versions of the inverters are quite different from this old style. They didn't send you a brochure for the inverter model that yours are clones of! It is the PIP-5048MG, as I mentioned earlier. See https://www.ebay.com/itm...

Voltronic Zoo Update I just updated my spreadsheet of the "Zoo" of Voltronic Power 230 Vac off-grid wall-mount inverters, including the specs that distinguish them from each other, and equivalent model numbers from MPP Solar , when they exist. It only includes current models, not all the past model...

Re: MKS-II-5KWB Repair Please help
Like paulvk, I worry that 9 of your panels in series may be sailing a little close to the wind, with regard to the maximum open circuit voltage of 450 V. How many cells are there in your 360 W panels? I see most with 72 cells, but some with 96 cells. Assuming 72 cells, I see Voc's of around 48 V at ...

Re: Aftermarket iMiEV battery upgrade project
That's great news. Am I correct in saying that you've shown you can access 80% of the capacity of the new battery? What was the lowest cell voltage it got down to? Do you have any hypotheses as to why you don't need (a) current unspoofing or (b) cell voltage spoofing? Surely that horrendous circuit ...

Re: How to tell a kilowatt hour from a kelvin week henry
This may also be of interest: Battery capacity is called C . This is in italics because it is a quantity symbol, not a unit symbol. Its units are amp-hours (Ah). In the case of lithium-ion batteries, we are concerned with the maximum rate (i.e. maximum current) at which they are allowed to be charge...

Here's something I wrote for a battery course for Electricians, about the relationship between amps and amp hours. It could easily be reworded to refer to watts and watt hours.

Re: PIP inverter repairs and hardware modifications
Not necessarily across the 15 V or 12 V supply, but at least involved in producing those supplies. Possibly the electrolytic across the supply pins of the PWM chip involved in making those supplies.

Re: Low cost BMS
That sounds good 4Springs. Although I've never felt the need to use explicit PWM, because when you just turn bypass on or off at the threshold (e.g. your lowest + 10 mV, no hysteresis), they will balance as quickly as possible, and when they get close to balanced they naturally enter into a sort of ...

And most importantly, the protection device closest to the battery must have a kA rating (interrupting capacity) that is greater than the maximum short circuit current of the battery. Otherwise, in the event of a short circuit, it will not go open circuit but will continue to arc over and will not p...

Re: Solar panels in series / parallel
If the 190 W panels have 72 cells and the 250 W panels have 60 cells, as is usually the case, that's a 6:5 ratio. That means you will only be able to match voltages if you have a string of 5 x 190 W panels in parallel with a string of 6 x 250 W panels. Or a string of 10 x 190 W with 12 x 250 W. If y...

So that means: 1 string - no fuse. 2 strings in parallel - no fuse. 3 strings in parallel - fuses on all strings. Correct. Because in the case of three strings in parallel, if one string had a failed diode in a panel, the other two strings would have enough potential to push current back through th...

Re: Solar panels in series / parallel
As to the inputs of those MPPTs, generally there's no problem with putting two separate arrays of equal voltage in parallel, but any more than three strings in parallel will need fuses on each string. I think that's right @weber ? No. Any more than 2 strings in parallel requires a fuse in each stri...
