Connecting The Batteries In Parallel
Why connect in parallel?
You are able to connect multiple EG4-LL batteries in parallel to increase the capacity and
current of your power storage system. When you connect multiple EG4-LL batteries in parallel,
you maintain the same voltage. For example, if I have two 48V 100AH EG4-LL batteries wired in
parallel, the output voltage will still be 48V. However, when wired in parallel, the capacity and
current limits are additive. In the previous example, you would have increased the storage
capacity from 100AH total to 200AH.
How do you wire your batteries in parallel?
Note: When wiring in parallel, you must ensure that the rest of your system can handle the
increased current limits. Signature Solar recommends that you verify the fuses and circuit
breakers downstream of your batteries can protect any components or appliances from current
spikes or short circuits.
1. Identify the positive and negative terminals on your batteries. These are color coded
red
for positive (+)
,
and
black for negative (-)
for your convenience.
2. Make a proper connection to the positive terminal of your first battery. Ensure that you
have followed directions to properly connect the cable to the terminal. Improper
connections can cause severe damage and may void your warranty.
3. Connect the other end of your positive cable to the positive terminal of the other battery
you are connecting to. Repeat step 2.
4. Repeat steps 2-3 for the negative connections on the negative terminals of your
batteries.
5. For additional batteries in your system, repeat steps 2-4 until you have connected all the
batteries together properly.
6. From the positive terminal of one battery on the end of the string of batteries, connect
your cable leading from your battery's positive side to the rest of your system.From the
negative terminal on the battery at the
opposite end of your battery string
, connect
your cable leading from your battery's negative side to the rest of your system.
