    Re: Fronius Inverters

    You are correct.
    To not lose the panels potential, you need a hybrid grid tying inverter.
    Fronius/Victron inverter is also more expensive than a Victron MPPT/inverter combination.

    I agree 100%. Each of us has our own issues to handle, as all is not equal ito supply by Eskom.

    Re: Talk to me about solar panels.

    Your sums can go either way, and all the way. Each home is different.

    For example, we are seldom above 500 units in winter and in summer like <200, and that is heating 2 x 150l and 1 x 50l...

    What must also be factored in, is the replacement costs of parts like inverters, batteries. They don't last indefinitely.
