Re: Solar panels in series / parallel

Not likely, the mppt just moves away from maximum power point if the actual power gets too high.

More likely that unit wasn't well designed from a temperature for back perspective

Re: Solar panels in series / parallel

Ah ok. I was hoping to have a 190w string and a 250w string in parallel (with a diode ?) and that the inverter would just see that ~4A and 6A as 10A combined at whatever voltage they averaged out to. It sounds like I need to source another 10x 250w panels with near enough the same voltage and curre...

2011 Ford Focus Conversion $8k (ex EV Trial)

Hi All, I recently got my Ford Focus working again. Brief recap - A previous owner let the original battery go flat (0v). The car was subsequently sold and the original battery binned. I acquired the car sans battery, and have now installed a new (to me) battery. Details: looking at 50km range (mayb...

Re: Charging failed

Hi Dave,

I do know the Zoe is extra picky about the resistance to earth (likely because there's no isolation between mains and battery)
not normally an issue in winter (when the ground is damp and the resistance at it's lowest)

do lets us know how you go with Renault.

Do you mean that Australia uses also J1772 Type 1, just like the US and Canada?

Re: We developed a charger. Please advice

I concur, looks pretty cool.

For a plug that you would keep in the car for the odd opportunity charge, this is way better than keeping one of every conceivable adapter.

My only suggestion, would be to add a J1772 type 1 input, as Australia has both forms rolled out

Re: tractor conversion

Yep, more or less. Do measure the rpm the motor spins at when the field is separately powered, and the motor controller is full on. If the motor is spinning faster than this when you connect the 2v battery to the field, the Regen current may be too high for the motor controller, which may damage the...

Re: tractor conversion

ah, what you are asking is very difficult with a series wound motor to achieve speed regulation would mean powering the field winding directly (ie 2V or so at 500A). you might get away with doing this with a 12v controller, powered off your 12v battery, though you would be controlling this manually....

Re: tractor conversion

The zappy h1 controller I remember being able to do Regen from a series wound motor.

You would need to move the brush timing back to neutral, and run a lower voltage.

Tbh, it's not worth trying to get Regen out of a series DC motor

Re: Soyachips’ Electric FZR250

That's some pretty thin wire, no wonder the voltage drops. The solution is to go to a 4 wire setup. I would trace out on the circuit board where the voltage measurement is, and connect that to the tabs separately. The other alternative is to lower the low volt limit by 0.3 to 0.4v, assuming the curr...

At 20A, the change in terminal voltage shouldn't be measurable

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.

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
