Voltage Protection
The EG4 battery is designed to monitor the voltage of each individual cell and ensure that they
do not become overcharged or undercharged. It constantly measure the voltage and will ensure
that each cell does not exceed a specific voltage while charging, or go below another voltage
while discharging.
Current Protection
The EG4 will measure the current at all times, and has built in protections against exceeding
specific currents while charging or discharging. These include built in timers that will shut off
quickly in an event of an extremely large amount of current, and be delayed for a short period
when the current is only slightly over the allotted amount. This ensures that the battery shuts off
quickly when there is a possible short or other issue, and prevents the battery from turning off if
there is only a minor current spike that would not result in damage or unsafe conditions.
Integrated Communication
Each EG4 is built with the user in mind, and designed to show you as much information as
possible as easily as possible. We include an option to connect to your battery and software to
monitor the status of your battery. This allows you to see and understand exactly what your
battery is doing, as well as allowing you to troubleshoot if you run into any issues.
Battery Communications
The EG4 line of batteries from Signature Solar offer a communication system that you can
utilize in order to monitor your batteries remotely, as well as to communicate with compatible
inverters. This system will allow you to program your system for optimal performance, and to
further protect your investment by allowing you to make changes depending on how you plan to
use the battery. Signature Solar fully supports assisting customers who have purchased an EG4
battery and compatible battery on making sure this communication is configured correctly.
Additionally, we have provided downloadable software from our website that can be installed on
a local computer and allow you to manage your battery or make changes directly. This software
can be located on our website at (
). We strongly recommend
watching our videos on how to configure this software. If you have any questions or trouble
while setting up your communication, please contact our customer service team for further
assistance. As a general guide, we have included step by step directions below that will work
with most systems.
1. Looking at the front of your battery, you will see 4 RS485 ports (these look like ethernet
ports).
2. To connect to your inverter, you will use the CAN or RS485 port. To connect to a
computer, you will use the RS485 port. To connect between batteries, you will use the
BATTERY COMM port. Insert the plug into the desired port.
3. Connect the other end of your communication cable to the device you are connecting to.
When connecting, ensure the main battery has the right dipswitch settings. For EG4-LLs,
this will be (Down, Down, Down, Up).
