Why do I need a starter kit not just the CellMons or WatchMon
We sell the starter kits to help customers procure the right components and avoid missing parts . The raw components are also available for those that are generally repeat customers.
Whilst the cell monitors (i.e. LongMon) will work without a supervisor "
When the Watchmon detects that the cells are outside their limits it will attempt to notify the connected remote system with a warning to alter operation. Ideally warnings brings the battery back into its operating limits. If the condition escalates the supervisor will trigger a critical event and attempt to interrupt the battery with a contactor / circuit breaker.
All the cell monitors need to be activated/commissioned using the supervisor to configure their operating parameters.
Part of the commissioning procedures also provide a method to verify that the cell monitor has been installed properly and should be completed prior to unsupervised use.
