Re: Small wind turbines

I have a 40 acre property 200kms west of Sydney. It is totally off grid. I have had PV panels and a 400watt wind turbine for over 10 years. acmotor's post above very accurately reflects my experience with PV and the turbine. The PV works less well in winter than in summer (no surprise there!) Becaus...

Re: Damn Chargers!

I will investigate the TSM chargers with OzDIY. I have met Graeme before.

Maybe the only plus the Zivan might have is that they have a distributor not far from me.

Thanks

Re: Damn Chargers!

Having had a "gutfull" of chargers blowing I am investigating buying a Zivan NG3 charger. The firm I emailed in the USA advised me: "Paul, We have the 240VAC 144V 18A Zivan NG3 chargers in stock. They sell for $1029 USD plus shipping. They can be programmed for 140.4VDC output." I wasn't sure if the...

Re: Damn Chargers!

Sorry guys but it turns out I gave you a "bum steer"! Got my brother over to help with the charger problem. When I hooked up the light, the cleaner and the heater, through the car, NONE of them worked. (Unlike last time when they all worked except the charger). And of course the charger didn't work ...

Thanks very much Richo and Johny, I will get my electrician brother over to help me (or more correctly - me help him) with an "electrical diagnosis" during the week. I will show him your opinions. Of the three things I tested, the 10 watt lamp and the 2400 watt heater had earth pins. The 150watt cle...

Re: Damn Chargers!

Thanks Richo

Just before I go have a bo-peep at the breaker I am confused. While the controller and the breaker are both part of the vehicle's wiring, they are not part of the charging circuit? Or are they? I don't understand.

Sorry - just showing my lack of knowledge!

Hi people, After having two chargers blow simultaneously I bought two new KPES chargers. I installed one and hooked it up to the existing wiring in the car. The existing wiring consists of 3 prong connector under the petrol cap connected to an on-off switch connected to a 15amp circuit breaker conne...

Re: DC - DC Converters?

Thanks Johny,

My pack is 140v at it's max but normally sits around 133v. So what your saying is that a 144v converter would have no trouble working off a 133v pack?

Thanks

DC - DC Converters?

Hi people, I have been continually adding cells to my EV to the point where my original 96v pack is now 140v (40 cells). Almost all components have been replaced to handle this increased voltage except for the 96v motor and the DC - DC converter. The converter is run in parallel with a solar panel t...

I have always bought the enable option to keep things simple. I did purchase two of...

Excessive heat seems to be a common thread in some of your replies. I don't know how hot the chargers beco...

Two chargers blow simultaneously.

G'day people, I am not having much luck with chargers! About 18 months ago I decided to fit two chargers to my car. Use one by itself for 10 amp circuits, use the second one for 15 amp circuits and use both together when charging from 32 amp public charging stations. I bought 2 of the new small TC C...

Re: Solar Panel output: Rating versus Reality

Just a bit of a warning. About 3 years ago I purchased a flexible panel to put on the top of my EV to keep the aux battery topped up. Saves me having to use the DC-DC converter. The panel conked out after about 2 and a half years. When I purchased the panel I also researched methods of attaching it ...

As a reconfirmation it is the panel you could measure with a DMM the PV output before charging then after the 20min when panel cuts out.
Yep Richo it was the panel.

I better start hunting around for a new one.

Hi people, My investigations were somewhat interrupted by the flu so I didn't want to visit anyone and pass the flu along.

Re: Aux battery charging problems

Thanks Richo, I managed to check on the wiring yesterday. My multimeter showed that the controller's display was accurate. I then stripped some of the insulation off the two wires where they come out of the panel which eliminated, as possibilities, voltage drop or some sort of hot spot along the len...

Re: Aux battery charging problems

Thanks Richo and Coulomb 1. Did it ever work? I think it did a year or two ago. The previous controller didn't give me an instantaneous figure for current charge or pv voltage. I replaced it because I assumed it must have become faulty at some stage. It wasn't until I recently bought a new controlle...

Re: Aux battery charging problems

Thanks Richo, Can you actually charge your aux battery to 14V by any other method eg lab power supply? I have a 12v charger which charges the battery up to 13.5v at a rate of 1.7 amps. The battery then sits at 13.4v until I use the car again. The controller will go into what the manual calls "Bulk C...

Thanks coulomb, Is it 4 LiFePO₄ cells? Or some other lithium chemistry? The battery is marked as a Fusion Lithium battery V-LFP-12-26Ah so I assume it is LiFePo. How are you measuring the charge current? It sounds to me like a voltage drop issue. What wire do you have from the charger to the battery...
