a new status is needed to communicate that no update was sent to the inverter because its power limit is still valid. in this case, calculating a new power limit is delayed by an exponentially increasing backoff. the maximum backoff time is ~1s, which is still plenty fast. the backoff is actually necessary for another reason: at least currently, a lot of debug messages are printed to the console. printing all that information in every DPL loop() is too much.
