are two types of grid connected battery options
when connecting to a solar system. One is called AC-coupled
and the other
is DC-coupled. The AC connected system is easier and less
costly to add
to an existing solar system. The DC connected battery
you current solar inverter with an inverter that manages both the solar
batteries, however it is a bit more efficient. In my opinion,
worth replacing your existing solar inverter, however, there may be
advantages depending on your situation. Here is an article
discussed these two options and here
is a good video.
is an article
provides some information on inverter selection. For example,
for the SMA
SunnyBoy, you would typically install the SMA Sunny Boy Storage (the
version of Sunny Boy Island) although some batteries include their own
such as the Tesla Powerwall and Sonnen.
Here is an article
comparing different battery options. The
article is from Australia which has a lot of experience in this area
of the information on the major batteries such as Tesla, LG and Sonnen
valid in the US as well.
prepared to have your main
service panel redone so that it can isolate the loads in your house and
solar system from the rest of the grid during a power
outage. This is
called a critical load center. The system also needs to ensure that no
can leak onto the grid while the power lines might be getting worked
the system cuts ties with the grid, it can incorporate any connected
system and trick it into thinking the grid is present by basically
own micro-grid using its battery pack.
solution is portable
generator either powered by gas or one that has a
battery and can be charged by a regular outlet or by a solar panel.
These batteries that can be charged by solar
are often called a "portable solar generators". Here
are a couple articles that review the
pros and cons of these options. There
also a new option from EcoFlow called the Delta 1300.
