Re: EV comparisons (UK)

Two motors increases your power losses which are generally considered to be around 20% (in this case x2 for the dual motor) and confirmed by the EPA’s figures......it’s basic physics. That depends upon whether core (magnetic) or copper (resistance) losses dominate going to two motors doubles the (u...

Re: Insurance coverage while charging

sometimes with insurance, less is more.

Good that Budget direct are going to state that they definitely do cover in that situation
At present it's more an assumed situation (same as when a petrol car catches fire and burns a building down - which happens quite often)

Re: Prelude conversion project - some questions

check the 12 cell module attached to it - the shunt may have failed on (0.1A * 300 hrs)
it's probably not, but easy to check when you first crack the battery open.
would also mean you could just charge the cell group back up instead of bypass

Welcome Kingglade Hopefully the local branch can help you in the engineer sign off department On your proposed components: the Curtis 1231C is a very old analogue unit. unless you already own it, I would suggest getting something more modern.

If it really does support pylontech batteries, then you could use a BMS that uses the same communication standard

Re: How DC chargers work

Round trip efficiency on compressed air is pretty bad, around 45%, gets worse when trying to go higher pressure to get the volume down. Not terrible for storage between seasons in the right circumstances. Energy density is terrible too, both in weight and volume. Worse than hydro. 100kwh usable you'...

Re: How DC chargers work

I wonder if lead acid would be a reasonable option for this situation. at 160kwh, deep discharges would be rare (unless it's part of a VPP) 50 x 300Ah Gel batteries would be around $25k with a 50kw DC fast charge, that would only be a C/3 discharge rate (more like C/3.5 or C/4 if the grid is contrib...

what if you used a battery charger as the load? there's heaps of cheap 48v chargers out there - and then it doesn't matter if you leave it on the whole time the generator is running or not

Re: How DC chargers work

what if you were to scale things down a bit? maybe go for a DC not so fast charge a couple of old leaf batteries would get you to 30kwh, keep the 13kwh of solar (obviously this isn't the expensive part) you could 50kw fast charge till the battery is dead, then slower charge at the combination of ava...

Re: New Kona Owner: home charging advice sought

Why wouldn't the 3-phase version of the zappi be able to work on 2-phases (also, I've never heard of a 2-phase connection in Australia, is this on a SWER line?)

The zappi would measure each phase independently, so the 3rd phase would just be treated as 0 power all the time

Re: iMiEV charging, J1772 testing

Getting 130km to show on the guessometer, and actually getting 130km are two very different things. A battery with all 16kwh remaining can do it.

Re: jonescg's home battery storage system

However I am a bit perplexed as to why it can take 6.6kW of solar but only charge the battery at 2.5kW and output 2.5kW. I assume that it can do those simultaneously so, 2.5kW goes through to the inverter while it uses another 2.5kW for battery charging. Or even better would be to use 2.5kW for cha...
