display panel

 Hi just required new solar panels fitted and they never fitted the display
unit, which tell me if its working. Does the panel tells me that unit is
working and when its not. I haven't got the unit, so that is why I am asking
you. I have looked on the web and they looked complicated to understand, and
are they? if I buy one will they record MY panels. he governmant scheme is
that get free electricity when its light and what I do not use the Nat Grid
as the rest, as I have said I do not know when its producing or not

display unit... is that an inverter without a display, or something else?
(Extremely cheap inverter if it is!!).  Explain more

Does the panel tells me that unit is working and when its not.

Panels don't tell you anything -they just produce electricity
(that's if I've understood what you mean by "panel" - or do you mean "display
panel"). Again - more explanation, please

I haven't got the unit, so that is why I am asking you.
What do you mean by "unit"?  The inverter?
Or are you referring to a separate monitoring unit like a Watts Clever, Efergy,
Current cost, or other monitoring system

I have looked on the web and they looked complicated to understand, and

No - very easy to understand (if you're referring to an add-on system)

if I buy one will they record MY panels.

Depends on where you connect it to. If it's your system, yes, YOUR panels.
If you hook it up to the next-door neighbour's solar array, do you think it
would monitor YOUR array?

If you're referring to an inverter, no, they only display voltage, current,
grid-lock, error messages etc - they don't RECORD anything.

That's left to the electricity meter, albeit it would only be the DIFFERENCE
between what you're using and what you're producing. Some time during the middle
of the day, when the panels are producing the most power, it could be recording
what you're feeding back. (solar power less the power you're consuming). At
night, it WILL be recording what you're using (no sun!!)


he governmant scheme is that get free electricity when its light and what I do
not use the Nat Grid

Now you've got me - I think I need an interpreter

If all this is about some sort of monitoring on the DC output of the solar
panels, then find a friend who is an electrician. He'll explain what a
multimeter is, and what it can do
