Battery Bank Discharger

[Snake00x]

Hello Im new to this type of thing but maybe someone here can help me with this question:

Is there a way for me to discharge my battery bank to my grid-tie inverter so that the power goes to the grid?

Thank you

What type of Grid Tie do you have?

Well Im looking at upgrading for my business, and Im looking at this one PowerGate Plus 500kW 480/3.

The bank that I am looking at is about 24 forklift batteries: 36V 2100Ah capacity in parallel.

Im just not sure if that will work, and those solar companies arent much help, plus asking the utility company is out of the question because I know that will be a dead end.

Thank you

Yes, those kinds of inverters are very common. They're
designed to take the power from Solar Panels at some
specific DC voltage and synchronously inject it into the
grid.

The control system needed to perform the synchronization
is quite sophisticated and rather costly.


You may need to arrange your batteries for a higher voltage
in order to make the system viable.

If you are using a GRID TIE inverter then there is no where for the power to go except into the grid. (as long as YOUR voltage supply is high enough)

If you can supply (overall) more power than you use then you can run the meter backwards .....
BUT...

How are you charging the battery bank ?

The least difficult way to put power back into the grid is
by means of an "Induction Generator." An ordinary induction
motor will function as a pure sine wave generator when
driven by a DC motor at about 110% of its rated rpm.

It will maintain synchronization with the grid 'automatically'
when properly driven and does not need any sort of
controller system other than simple switching.

It is also possible to use an induction motor as a stand-alone
alternator.
