    Lights Flickering when on Battery Mode Axpert

    Yes Chris, exactly my point when I asked the question in the beginning, does the neutral remain earthed when in inverter mode? It should be.

    One other question, Rick C: Is your neutral still connected to your appliance earthing system when you are not running on mains, i.e. running the inverter? Without your neutral being earthed properly at the supply (in this case the inverter), the system is prone to all sorts of interference.
  3. Apart from the advantage of having the sun shine perpendicular to the panel, a flat lying panel will "see" a longer day in summer due to exposure to the arc of the sun which can be more than 180 degrees from sunrise to sunset.

    The high pv voltage usually feeds the mppt. The MPPT works like a DC step-down Transformer and this lower voltage matches the battery voltage for which the inverter was designed. With a system like that, there is a lot more flexibility in that the input voltage may change significantly without affecting the output voltage of the MPPT. E.g., to charge a 48V battery with a low PV voltage, would mean a change in Mppt output a lot quicker than if the PV voltage was higher. In general the efficiency improves with a high PV voltage. A further advantage of high PV voltage, is the fact that the current is low and the cables can be thin.

    The value of a good monitoring system

    This makes perfect sense. Is it solved now? What have you done to create the required isolation?

    Where on the Axpert can I get any logic output only while the inverter is running?

    "Quote": then ICC will switch the system to supply loads via the grid....... Does this mean some external device, or is this an automatic feature of the Axpert? Thank you for the info Pilotfish!

  11. Welcome to the forum! I am sure someone will have more info on the Infini, but as far as I understand, it is similar to the Imeon 3.6. which means that it can feed back to the grid, a feature that you will have to block if you are using a pre-paid meter.
  12. Hi Plonkster, I'll PM you later with more details.
  13. Good evening all forum members. I have a strange request.

  14. Hi Jason,

    I've been absent for a while due to a lot of unpleasant circumstances. Chris-R contacted me recently, I replied a number of times, but now it seems to me that he is absent from the forum. How can I contact him please?

    Kind regards,

      Thanks Jason! I did send him some messages, but without success. Let's hope all is O.K.

  15. I am a little more enthusiastic about supercapacitors. If used in conjunction with for instance LP type Ni-Cad or Ni-Fe, you could have the best of both worlds, so to speak. Long life and very deep cycling characteristics of the LP types (with no or very little harm). Now you can run a "soft" load for very long periods AND have the punch when needed to start and run heavy loads, especially in daytime. Just my thought......
