Re: V2H with Chinese offgrid inverter

Well, if it weren't for the 3 kW power limit which wouldn't support cooking on more than one plate. I was wondering about increasing the limit by running two or more in parallel. Probably not the best design plan I'm guessing, though not an expert and my background is more pharma QC & AR&D ...

Re: Off-grid inverter feed with a 12Volt alternator

Can DC energy produced with a 12 volt alternator be converted to AC energy with an inverter? The alternator is variable speed. The operating voltage is fixed at 13.5 volts and the current produced varies between 45-110A depending on the alternator speed. Well yes... especially if the alternator out...

Re: Car inverter as a 3 phase inverter ?

You definitely need filtering, I have destroyed a laptop power supply when I omitted the filter. Also transformers tend to transform the nasty spikes as well. I'd estimate the magnetics to be heavier than the inverter if you're looking for more than 10 kW. Is the LLC Resonant Mode Converter Design ...

Re: Car inverter as a 3 phase inverter ?

The main problem I see here is that a car inverter outputs PWM, not a sine wave. I'm not sure how problematic this would be, but I'd be hesitant to run household appliances directly from such an inverter without putting some thought into filtering it. I was under the impression the output of a Priu...

Re: Does Anyone Have a Prius Gen 3 Inverter, A DC Power Supply, and Some Way of Measuring Output Voltages of The Inverte

From what I can see on the Toyota gen3 specs they use the boost circutry on the 208vdc battery and outputting over 50KW on the motor so the boost circutry should be able to cope with around 250 amps if I understand this right. But something is definitely limiting power, so continue investigating. A...

Re: Are there Gen 3 Prius inverters to avoid?

Larry, where in the world are you? I *think* some of my cables are for a Gen3, but were mis-identified when I purchased them. In the USA Toyota had a recall on the certain Gen3 inverters, I would certainly avoid ones from the models affected; that may be moot as they are about 3x the cost of the Ge...

Re: Free rev3 boards

You didn't! Oh man... what little I've read... sounds like these are what I can use maybe for the Gen 3 inverter-converters I invested in... as well as maybe the one Gen3 CVT as well?

Time to find the BOM and ask you what shipping looks like to the States, i.e. Michigan.

Re: Using the Prius Gen 3 Inverter Logic Board to go off grid

I've done a single phase version of it for the Gen2 inverter: https://github.com/jsphuebner/stm32-island It uses phase 1 and 3 and also the boost converter to keep DC link voltage constant. So it requires a battery voltage lower then mains peak, say below 300V. You need to attach quite some magneti...
