    It takes 10 seconds for my inverter to rebalance itself, if watching for the constant red light to turn off on the importing meter, is to be trusted - perhaps it is the fancy electronic importing meter that takes 10 seconds to work out what is happening?

    The inverter is a "Power - one Aurora".

    As a matter of interest John, which energy monitor do you use? I have the similar Aurora Gizmo as you; have you thrown your desktop gizmo away? :)

    I still have the desk top gizmo - it sits on a shelf in the living room.
    I have had a go at "playing" with it (big mistake - I got it into a right muddle and had to mess about "restarting" it) but I now keep it on the standard setting.
    The graph and the wattage being produced is really useful as a guide to what is happening today (it currently displays something that looks like a light house on a saucy seaside postcard.)
    However the update cycle is minutes not seconds and it turns itself off again PDQ.

    My wife has a spare bedroom/office, which she likes to be hotter than the normal back ground temperature of a bed room - it so happens that if the "office" door is open and so is the the hall cupboard, then her 1,500 watt "comfort" oil filled radiator aligns with the electronic importing meter and its constant red light.

    The radiator has three settings presumably 500 watts each. So I was demonstrating that the 500 or 1000 (or even 1,500 in theory) could be run on maximum thermostat for free but turning on 1500 and turning the thermostat right down was counter productive and not the most economical setting.

    [As the old saying goes "You can lead a user to a manual but you cannot make then think"]

    The "office" is in the part of the building that has been cavity-filled recently, using nucleated graphite filled expanded polystyrene, as well as being double glazed a few yeas ago - so even on the 1000 setting "the office" was heading towards "sauna" classification by 14:00.

    As you know, I have a similar make and model Inverter, I also had a similar DeskTop monitor, until it had an accident with a brick wall (useless bit of kit); what do you mean by 'inverter to rebalance'? I take it you have a Gen meter + an Export meter (import meter) fitted to your system? Getting confused here .com. :question:

    Back to the office for what it's worth.....1kWh today.:eek:

    3.8 today, turned out quite nice. 1.6 yesterday, not so nice.

    Good weather ahead (hopefully) for the next week or so, so hopefully pull back a few lost units, but probably below Nov target.

    Not too bad though.

    Mart.
    Mart. Cardiff. 5.58 kWp PV systems (3.58 ESE & 2.0 WNW). Two A2A units for cleaner heating.

    For general PV advice please see the PV FAQ thread on the Green & Ethical Board.

    Perhaps I should have said "system" to rebalance.

    My electronic importing meter has two red lights (because it is "economy 7 and incorporates a time clock). If the meter is importing it flashes 1 red flash per watt. If electricity is being exported the red light glows constant red.
    If one turns on something one know must convert the system from exporting to importing, the result is not instant. It takes 10 seconds for the red light to turn off - this ten second delay seems to be constant regardless of the size of the load imposed to exceed the generation from the inverter.

    Thursday: 1.3kWh
    Friday: 6.0kWh
    Saturday: 0.3kWh
    Sunday: 5.5kWh
    Monday: 2.4kWh

    Generation so far this month is 126.8kWh, so we've just nudged past the PVGIS Classic estimate of 126kWh, thanks mainly to the good start to the month.
