[MLB-WIRELESS] Solar power system

I'm hoping they have some zenners in that circuit, or the inverter
drawing 2 much will be very un friendly for the poor charge circuit,
sadly there is normally no protection on it. (As there is normally large
banks of batteries to take any slack)
You might also want to look at this issue,
The money you get back from this is negligable compared to the amount
they charge for there energy, so the most ecconomical thing to do, is
either detatch from the grid, or make the amount going back into the
grid quite small (by using it yourself),

If anyone needs and help / advice, feel free to let me know as I'm

Ahh no offence but what the heck do zenners have to do with this ???????

At last check , the normal function of a zenner diode was to limit a
voltage to it's
designed depletion zone break down point.

Not to mention the biggest zenner diode power rating I've seen is 1w ,
hardly suitable for a 1000w
solar system unless properly designed into a regulator.

There are **NO**  batteries, it's a grid connect system **ONLY**

The configuration is that the panels connect directly to the grid
connect inverter as per a NORMAL
grid connect system which is a much better way to do it in metro anyway
!!!!!!!!

Why waste your time, money and energy on batteries ?????  Get a UPS if
power interruption is a concern to you !

Unless your an off grid user in the bush the losses and massive cost
involved in charging / discharging 
batteries make them a waste of time.

And the thing that really pisses me off with batteries,  they are a crap
energy storage medium for cyclic use.

The recommended discharge on a cyclic system is something like only 30%
of their capacity !!!!!!!!!!!!!

I mean WTF !!!   Bring on super caps please !!!!!!!!!!!!!!!!!

But there are other rebate programs to cover that scenario if there's no
option anyway.

This system's advantage as per most grid connect systems is by reducing
your power bill by 
an average 4kw hours per day where your not drawing that power from the
grid.

(based on Melbourne's average 4hrs a day ish  of sun hours)

Ie , with this size system it's unlikely you'll put power back into the
grid 
but you'll get the saving regardless as .long as your using the power
normally 
during the day.

But the Govt announced a credit system, so you'll get the credit for the
power 
against your bill even if you don't use it during the day.

At the end of the day it's a great deal , and it's up to you to claim
your 8k gov contribution for this
if you see the value or miss out !

Cheers

Peter

	I / we make no endorsment of this but thought we'd share the
	opportunity,

	Some of you may have heard some of us talk
	about a deal on a 1kw grid connected solar system,

	Well they're running the promo again this Saturday

	(althought the deal seems to have change slightly)

	The current deal as I understand it ,

	Get a 13k grid connected solar system for $2500 upfront with
	$1k post installation cash back.

	And bring a friend and get an extra $250 off.

	This Saturday only 10 , 12 or 2pm at Clear Solar , 1/137 rooks
rd,
	Vermont

	Take your rates notice with your name on the to prove ownership
	of the property and a drivers lic

	It's being advertised on Gold 104 atm

	Quite a few of us opted for the larger more efficient 2kw
inverter too
	so you can
	Add more panels later without inverter replacement.

	Enjoy,

	Cheers

	Peter
