Function / description
The unit of measurement of electrical current.
Electrical current that changes direction several times per
second, such as supplied by utility grids & inverter output to
load current.
Incompatible with batteries directly.
The unit of measurement of cell capacity. For this and other
reasons, battery capacity is not specified in Ah, but instead Wh.
An electronic module developed for the purposes of
establishing serial communication (or improve the quality
thereof) between most BlueNova® batteries and capable
peripheral devices. Includes Wifi connectivity which, by
extension, allow for the remote monitoring of battery
performance & health variables via the BlueNova® Live Web
Platform –

A composite electronic system designed primarily to extend the
operational lifespan of batteries. Minimum core functionalities
of a BMS should include cell voltage balancing well as
countermeasures against adverse operation/conditions. The
BMS in BlueNova® HV batteries include additional non-
standard functionalities such as serial communication capability.
(where n = the number of hours required to hypothetically
recharge the battery from 0-100% SoC at constant current)
(where 1/n =
the number of hours required to hypothetically
recharge the battery from 0-100% SoC at constant current)
A serial communication protocol designed to allow for the
transmission and receival of serial data to/from multiple
interconnected compatible devices via a single common bus.
Internationally recognised & used.
Electrical current that flows in one direction only at any given
time, such as battery charge & discharge current and solar PV
supplied current.
The central component from which input energy is distributed
from one or more energy sources to the various connected
loads in electrical systems of a certain size. Apart from being
the primary distribution point in such systems, DB's also
promote overall safety by extension of the breakers & other
protective components they should be fitted with.
A system consisting of several different hardware and software
modules based control measures infrastructure typically used
to monitor, regulate & control the generation & transmission of
energy from a centralised operating system in large industrial
and/or utility-scale applications.
