You can easily clear this suggested maintenance reminder using the generator's control panel!

As I've written nigh previously, we purchased a 22KW Home Standby Generator from Generac a few years ago. Big standby generators similar this require maintenance to ensure they're functioning properly. Sometimes it's required maintenance (like replacing the engine oil) and sometimes it's suggested maintenance (like checking the battery is working well).

If y'all see a partially dark-green and yellowish light on your Generac generator, this is just a suggested maintenance reminder. There is absolutely nothing wrong with your generator, and information technology will still start automatically and run. These suggested maintenance reminders are time-based, and occur once a certain interval of time has been reached. Every year, for instance, you'll see this green and yellow light come on as a reminder to check the status of the generator's battery.

When a suggested maintenance interval has been reached, a Generac generator's light turns partially dark-green and partially yellowish.

Here I'll evidence y'all what the suggested maintenance reminder looks like on the generator and in the Mobile Link app, and how to set it so you only encounter a fully green light on your generator!

I first noticed the suggested maintenance reminder via Generac's Mobile Link app. After opening the app, I saw a xanthous triangle next to the typical greenish checkmark in the upper righthand corner of the home screen:

A yellow triangle is visible in the Mobile Link app, which indicates a suggested maintenance/service interval has been reached.

If you click on the Condition History page of the app, you'll see a detailed message regarding the maintenance reminder (in this instance – circled in cherry-red – the message says "Inspect Bombardment maintenance interval reached"):

If you lot open your generator, the control panel interface will explicate the maintenance reminder (in this case, a yearly "Inspect Bombardment" reminder to check the condition of the generator's battery):

If you lot get a light-green and yellow lite for battery inspection, the main affair you would want to do is check the voltage of the battery. Fortunately, you don't even need to exercise this manually with a voltmeter anymore! Just open the Mobile Link app, and you'll see the battery voltage displayed at the bottom of the screen:

The generator's battery voltage is displayed in the Mobile Link app.

Big standby generators essentially have 12V motorcar batteries in them, so every bit long equally the battery voltage is displayed in light-green and is somewhere between 12.6V to 14.6V, the battery should be fine!

How to Articulate the Maintenance Reminder from the Control Panel

Hit the grayness ENTER push button once, and you volition see the following screen request if service was performed:

The generator is at present dorsum to fully automatic arrangement operation (allows the generator to automatically beginning and exercises the generator according to the practise timer).

The control panel should look like this:
