UU lowvoltage error code residential generator
Could be the battery voltage. If your battery is not charging properly, the controller on the unit can do some funky things! Exactly how long does it run for? Is this in auto or manual mode?

My Kohler 17RES has stopped doing it's scheduled
On your Automatic Transfer Switch ( the little gray box you see on the right in the picture above) you have two blue buttons. One is a Manual test switch. The other has a clock on it and this is your exercise set button. Hold it down for a FULL 3 seconds if you want it to excercise without a load (not powering your home) Hold it down for a FULL 6 seconds if you want it to exercise with a load every week. Your generator will start and run for 20 minutes, and then shut down. Now every week your generator will exercise at the time and day that you pushed the set button.

Electrical cable size requirement
This is an answer to your question only. The safest thing to do is hire an electrician to do it. There may be factors you don't recgonize that a skilled eye would pick up on.
The proper size wire is #4 copper or #3 Aluminum. THHN is the most common and most versatile type in conduit. a #6 ground wire is ok. Stranded pulls a lot easier than solid and do yourself a favor and buy some wire pulling lubricant just in case.
Make sure to obey all manufacturer's instructions. If you use aluminum make sure to place anti-oxidation compound or Nolox on your lugs in the panel. Please write back with anymore questions.

Running when in standby mode
Are you sure this is not normal?
Read your manual.
Most of the larger generators do a test run once a week or so to make sure everything is working ok in case of a power falure.

Kohler 5ecd generator giving high battery voltage alarm
Fault code is displayed if the engine starting battery voltage rises above 16 VDC for a 12 VDC system or above 30 VDC for a 24 VDC system for more than 2 seconds when the engine is not running. This fault condition does not inhibit engine starting. The fault condition clears when the battery voltage returns to a voltage within the limits for more than 2 seconds
Check the battery rating and condition.

Kohler House Generator powers up when our electricity goes out but then powers right back down?
That is an engine running issue, not a battery issue. :>D The first thing to check would be fuel supply. Can you start up manually and keep it running. If you can, it is the contactor that senses your loss of mains power and switches the generator on. It is not maintaining the connection, or is is misdiagnosing the power from the generator as power from the mains.
