Should I put a battery backup on my existing solar system ?

To determine the correct answer to this question we need to ask some questions !
Q: How much of your electricity consumption does
your existing solar system cover?

A: Depending on when the system installed and
whether or not you have/had a feed-in tariff,
your system may only generate enough power to
meet a small portion of your electricity needs – or
it may generate more than you actually need. This
will dictate the best approach for sizing your
battery storage. If you need advise give us a call
about how to retrofit a system to optimise value.

Q: What energy storage system size would best suit
your needs and budget? Do you want to go off-grid
at all costs (possibly to spite your utility), or do you
view energy storage as an investment to
complement your solar PV?

A: Your answers to these questions will help you
determine the best system size.

Q: Will the system provide you with back-up power?

A: This is not a given with battery storage systems.
Only certain battery storage systems will allow you
to access your battery power when the grid is
down – make sure you ask.

Q: Should you install batteries now, or just get a
battery-ready inverter?

A: If your system is over 5 years old and due for an
inverter replacement, this might be a good time for
you to consider installing energy storage – or
perhaps just a battery-ready, hybrid inverter. Even
if you don’t install batteries right away, a hybrid
inverter will ensure that batteries can easily be
installed at a later date.
