  1. Re: Main battery getting fried in Toyota Landcruiser Bakkie

    Yes the voltage can go up if the regulator is causing overcharging. Bear in mind a regulator can also undercharge and then the voltage will stay lower than normal.

    Re: Average working time for solar

    Power generated per day works out at about 901Wh per sq m of solar panel in my case.
  3. Re: Main battery getting fried in Toyota Landcruiser Bakkie

    To fry a battery in one day seems to be some kind of fault. As a regulator for the Denso alternator is less than R300 I would go that route if someone cannot actually test to find the problem. I...

    Re: Average working time for solar

    Thanks.
    Funny that I have never generated 1kW/sq m yet the inverter gives the 5h52m value.

    Average working time for solar

    I wonder if someone can shed light on the way Average Working Time from the inverter is seen as 5h52m when in fact it is generating power over a 10 hour period (07h00 to 17h00) as per the graph...
  6. Re: Connecting Different Solar panels in Series or Parallel

    Great article. Thanks for sharing. If one looks at the examples one will find by using a MPPT for the flexible 24V panel it could yield about 9A by itself. A PWM would restrict the current to about...

    Re: Battery Behavior

    Interesting the device you have to up the volts to 24V for the starter.
    The better reading would be to measure the actual volts on the starter during cranking. This should be around 18.5V min for a...

    Re: 12v pressure pump

    You could try the Shurflo I think 2190 as a lower pressure 5.5L/min pump. Not sure about the noise but pressure is good. I have seen it at Silver lakes Camp world. Cost about R1300.

    It is also a...

    Re: Best solar yield yet

    You are getting a really fantastic yield.

    Can you perhaps share what make and Watts of panels you have installed?

    What make inverter?

    Re: Best solar yield yet

    3x270W
    Solis 4G grid tied.
    No storage.
    System size to cover base load and not to export. Suddenly the daily yield went up from 3.5 to 4.4kW.

    Best solar yield yet

    After 3 days of lower yield than during winter today was a turn around and my total yield shot up to the best level in 13 months.

    How did others find the yield today?
  13. Re: How do the ridgid panels fare on caravans and canapys

    The problem that is alerted to is that your panels will be able to supply more current on the battery side than 15A. You will be limiting your charge rate to 15A.
    100/20A will be a better option to...

    Re: Inverter and charger combination

    I would pass this inverter. Too many false claims as it is not pure sine a lot of things will not work as claimed. Also claimed as 12/24V?
  24. Re: 12V Battery Charger gives you a small electric shock on the charge leads?

    Does it have a 3 core supply lead or only a 2 pin. If 3 core check earth back to socket.

  33. Re: which solar regulators can be used in vehicles??

    My take on this would be you can use any 20A controller BUT the 2nd battery must not be earthed.

    It would still control on the negative side without a problem. Also if you use the load output of...
