ROAMER 24-230SMART3 User manual

A) Check that your phone is within range of the battery (approximately 5m). If in doubt,
place the phone on the lid of the battery for maximum signal strength. Check that your
phone/tablet’s Bluetooth is enabled, and you have allowed all permissions requested by the
Roamer BMS App. On Android phones this includes GPS. Click “scan” at least twice and if
that still does not work, force close the app on your phone and reopen it. Check that another
phone/tablet is not connected to the battery as this blocks any new connections. Place your
battery on charge, a completely flat battery may not be able to connect correctly.
A) There are a few reasons this could be, the first step is to determine if this is an internal
battery issue or an external cabling/equipment issue. You can verify this on the Roamer BMS
app home page, look to see if either charging or discharging button is turned off (button will
be greyed out if off –this means it is in protection mode). If it is in protection mode, then
check the protect state page for the corresponding error code. If all is functioning normally,
the only buttons to be highlighted orange would be CHG (charging allowed) and DSG
(discharging allowed). Please see app section of the manual for error code descriptions.
A) The Roamer BMS App estimates the remaining percentage based on the current flowing
in and out of your battery. On the first charge of the battery this Ah remaining value may be
out of calibration and show a figure that is much higher than should
be possible for the battery capacity. The battery will therefore require a full cycle including
discharging down to the Pack Low Voltage threshold (10.8V for a12V battery, 21.6V for a
24V battery), this will reset the app to 0% and 0.0Ah remaining and it should count
accurately after this. Please note that the app reading for the battery state of charge has no
effect on the operation of thebattery, BMS protections for over charging and over-
discharging are based on voltages only. Even if your app is out of calibration and incorrectly
reporting the state of charge, the battery will still operate normally and all protections will
remain in place.

A) Inverters have large capacitors to smooth the current flow in and out of the equipment,
on first connection this can cause a surge current from the battery of up to 4000A. When
this happens, the BMS will go into protection state with a protect code of ASCD (Automatic
Short Circuit Detection) and both charge and discharge will be switched off. The solution is to
isolate the battery using the main battery switch (or remove cables) and wait for protection
state to reset. You can then pre-charge the
inverter and reconnect the inverter. Please see ‘discharging’ section of the manual for tips on
pre-charging.
A) The parameters page contains important settings that control your battery’s operation.
We do not allow access to this by default as it is possible to cause damage to your battery if
parameters are set incorrectly. Accessing the parameters menu without Roamer’s permission
will invalidate your battery’s warranty. The password will be provided through a support ticket
if there is a need to change your parameters to resolve an issue.
A) Please get in contact with the Roamer Support Team on [e-mail] and we will
be more than happy to assist. Please provide your battery model, serial number, and order
number along with adetailed description of your system and the nature of the fault. Where
possible, please also provide screenshots of the home page of your Roamer BMS App, full
details page, and the protection state page.
