If your UPS supports writing battery\&.runtime\&.low, the new set value is to be entered in minutes (up to 99) but the reported value is reported in seconds (set value * 60)\&.

If your UPS supports input\&.transfer\&.low and input\&.transfer\&.high, those values are used to create an allowable output range\&. The UPS will do what it can to keep the output voltage value within the defined range (for example: tap change or switch to inverter)\&.
