Pulse asks /pulse/available-capacity for the site's headroom: the sanction minus the safety margin minus the site's total load right now. Pulse adds DC60-002's own output back in to get its charging limit. A negative headroom means DC60-002 must come down. When our meter data is too old, Pulse gets an error instead and falls back to its backup limit.
