...llo, I have a Best Ferrups 3.1KVA and I noticed that the percent battery voltage reported from upsc never gets above 69.9%. I believe there is a mistake in the driver. The battery percentage is calculated based on the High Battery Alarm Setpoint (59.6V) instead of the Ideal Voltage which is about 54V (4 batteries x 13.6V). I examined the source code and found that the variable fc.fullvolts is the result of querying parameter 67 from the UPS. This parameter is defined per Ferrups Tip 503 as: "The battery voltage at which the UPS sound a High Battery alarm" A better value to use in d...

...91.9.I SMART-UPS 3000 XL D1 82.9.M SMART-UPS 2200 RM Note: The voltmeter in the ups depend on the correct setting of the region code. After the "Big Reset" (^Y), my European 230V SmartUPS 2200 thought it were an US Smartups 450; suddenly the battery voltage read 27V instead of 54V, the expected input voltage became 110V etc... I suspect that an overloaded converter might go undetected if the model version is incorrectly set (haven't verified that theory, for obvious reasons). m: Manufacturing date, actually arbitrary string (8 char) n: Serial number, actually arbitrary...
