Error Codes
5.1 Function Checks
It’s recommended to periodically check if the system is operating correctly, and
ensure that it hasn’t gone into fault mode. In addition, end users are encouraged to
get an understanding of the operating principle, enery behaviour patterns (whether
battery charges to 100% daily, extent of discharge overnight, house loads etc) to
ensure your monitoring data aligns with your actual energy usage. If any unusual
behaviour does occur, contact your system provider or manufacturer for further
support.
5.2 System Faults/Errors
The Battery alerts the user to operational status using a wide range of Error &
Protection codes (as described below). Please note that the system is capable of
self/remote diagnosis whilst operating in Protection mode and is expected to return
to normal operation thereafter. Please contact your system provider or Alpha ESS if
the protection code persists for an extended period.
If the system displays an Error Code (as shown below), please contact your installer
or system provider urgently for further resolution. Do not attempt to resolve the
error by yourself or with the help of an unauthorised (non-Alpha ESS) technician, as
this may void the Warranty of the product.
