JFY JSI-2000 inverter failures

posting here, because notes online are google searchable and much less likely to go missing than if I put them on my laptop somewhere I have a JSI-2000 that reported a failed output relay. JFY accepted my warranty claim and then fell off the face of the earth (though this happened right before chine...

Re: Antiscab's NWH10 Prius plugin Lithium conversion

My thinking was, the capacitor pack acting as the traction battery and a constant drain of 40 amps once the voltage exceeded (?) volts and that fed into the 40Ah aux LFP battery in the spare wheel well. If the LFP cells were swapped out for LTO cells, could they be charged faster? I can't imagine a...

Re: Antiscab's NWH10 Prius plugin Lithium conversion

optimal ICE sizing in a hybrid application is a bit of a balancing act. peak efficiency (which is what matters in a hybrid) improves as engine size goes up. energy lost to maintain temperature also goes up too. That's one of the reasons the engine size in the prius has been getting bigger as time go...

Caps in parrallel would help mask a bad traction battery.

Re: Antiscab's NWH10 Prius plugin Lithium conversion

a very long overdue update on the second prototype. I'm using 200 x headway 38120s cells for 320v 20Ah nominal The cells are built into 5 x 40 cell modules (64v 20Ah each) with wires for 2 x zeva EVMS 12 cell monitors each, and a separate set of wires to go back to the cars original battery ECU IMAG...

Re: 240VAC to 370VDC variable charge rate charger up to 5KW.

I imagine that most if not all production EVs do provide that isolation, but since the battery is always hidden away, perhaps some don't. LEAF and iMiEV on-board chargers do isolate. Zoe is the only production EV I know whose charger isn't isolated input to output (motor windings are used as an ind...

Re: 240VAC to 370VDC variable charge rate charger up to 5KW.

I have a few dead TC Chargers on my shelf. The input PFC stage boosts to 370vdc natively, and from what I remember, it's not overly smart. I'll see if it works from 48vdc - that may be your cheapest solution. They would only be good to draw up to 15A from 48v though you would only have the option of...

Re: Feedback/Conversation on Preferred Smart Charger

Another option, according to SolarQuotes, is to install an additional 1kW of panels to offset any emissions caused by charging an EV over the grid. Although, in WA, and Synergy's restrictions on inverter sizing, this isn't much of an option at the moment :) in WA, with a battery, you can install mo...

Re: 240VAC to 370VDC variable charge rate charger up to 5KW.

the elcon/TC Charger will also work with an input that's as low as 90vac or 100vdc, albeit, at significantly reduced power

There's also openEVSE that can do solar limited charging, though that is not as well documented What battery setup do you have? That will affect what will talk with what - I'm assuming the idea here is to prevent the house battery discharging into the car battery? some also give the option of contro...

Re: Grid Tie inverter / charger with AGM batteries

Re: what is peoples thoughts on Active Equalizer Balancer Boards?

That looks cool. Might be worth testing with second hand cells? More benefit on cells that have more variation to start with. Though I do worry that if it's always balancing on voltage, higher resistance but higher capacity cells get charged at the expense of lower resistance lower capacity cells. I...

Re: Grid Tie inverter / charger with AGM batteries

I just realised I didn't actually answer your question - the 48v inverters have traditionally worked with lead acid natively, getting them to work with lithium has been the real trick.

The default is usually a 3-stage lead acid charge profile (voltage and current limits configurable)

Re: Grid Tie inverter / charger with AGM batteries

Where are you based? you would likely get more bang for your buck taking some loads off grid using a large 96v UPS and adding more (offgrid) solar to support using second hand gumtree hardware, assuming you have space for more solar. That solution is several $100. Do you have an export limit? What i...
