This reads data from Multi-RS systems (and potentially also others in future) and combines/summarises data for three-phase (and later parallel) units that are part of the same system.
Right now it keeps the ESS parameters (minsoc, mode) the same for the whole system. It keeps the AC input limit the same. It can be configured with a Custom Name.
This (mostly) mirrors the paths from the Multi-RS service. In all cases (except where noted), the setting is simply mirrored to all the units in the system.
Notes:
- In the current version, the AC power setpoint is simply divided by the phase count and distributed to the individual units. A better implementation will be added to the Multi-RS firmware in future.
- The ESS mode values are:
- 0 = Optimised with BatteryLife
- 1 = Optimised without BatteryLife
- 2 = Keep Batteries Charged
- 3 = External Control
- The MinimumSocLimit is simply copied to all individual units so they all start/stop discharging at the same SOC.
/Mode <--- Switch position, sent to one RS, RS already syncs this
/Ess/AcPowerSetpoint <--- AC power setpoint
/Settings/Ess/MinimumSocLimit <--- Minimum SOC limit for ESS
/Settings/Ess/Mode <--- ESS mode
/Settings/AlarmLevel/... <--- Disable, warn, or only alarm.
The following summary data is calculated from the information provided by the individual units.
/State <--- Summarised state of the system
/Ac/In/n/CurrentLimit <--- AC input current limit for input n
/Ac/In/n/Lx/I <--- Total current drawn on phase x, input n
/Ac/In/n/Lx/P <--- Total power drawn on phase x, input n
/Ac/In/n/P <--- Total power drawn over all phases
/Ac/NumberOfAcInputs <--- Number of AC inputs
/Ac/NumberOfPhases <--- Number of phases
/Ac/Out/Lx/I <--- Total current drawn on output
/Ac/Out/Lx/P <--- Total power drawn on output
/Devices/x/Service <--- List of service/instances that make up this service
