Grid Connect PV systems

Cheaper in the long run to put an extra panel out? (Extra cells cheaper than regen argument :-) Exactly, given relatively exceptional aussie insolation endowment thanks to it geo position the tracker is not worth it. The direct route of adding extra panels seems more plausible, exceptions might app...

Thundersky battries on there side?

Even though the situation improved by finally making available assembly blocks to hold cylindricals by other means than fragile contact points, I'd say they are still somewhat less sturdy form factor in comparison to large capacity prismatics. Mind you this is automotive application, you are expecti...

I'll post it when/if it comes, there is some preliminary ballpark figure on those Emrax motors around $3k quoted as base for US customer. However, pursuing multiple inquiries is welcomed as it will send a message to the factory there is building up of interest.

Vehicle weights post EV conversion

Sorry for highjacking the thread slightly. Richo, I'm wondering why didn't you opt for the Tuarn/Mal method of braking the packs via contactors into smaller ~48V divisions? Was it because of the factory BMS from Headway, which you modified? So, you are using only two -ve/+ve EV200s then? Or am I mis...

Fuji variable speed drive any good?

Interesting similarities there, 12000rpm multi-lol; however ACP introduced some dielectric inside their ver. of emotor - so it worked as charger with their inverter as well. Also they supposedly outsourced the manuf. based to asia few years ago, not sure if that meant both emotor + inverters.

That's true, but the market for clean/not rusty MGs and Minis will be drying up with progressing time and that's the factor I tried to address here.

There should be on the market already a new gen "the grey series" of Calb batts (part of "Thundersky" holding) which are specific ev-conversion form factor ready, i.e. upstanding connectors but not those high cases anymore, these are wide and short.

Always read the fine print, it sais EVO tested on 600VDC inverter, so how severe would be the derating on WaveSculptor or any other lower sitting "mid" voltage inverter, matter of minus (1-3%) from that 96% or more?
