Frequently Asked Questions

How can I make sure my generator works in cold weather?

A cold weather kit or battery warmer helps a lot. Generators can be a little grumpy in the cold, so these accessories help it start easier when the temps drop.

Can I use the same accessories on different generator brands?

Some accessories are universal, like inlet boxes or covers, but others—like maintenance kits or monitors—are brand-specific. Always check the model details before buying.

What’s a transfer switch, and why do people keep saying I need one?

It’s a must if you want to safely connect your generator to your home’s electrical system. A generator transfer switch switches your power source from the grid to the generator without you having to mess with extension cords or risk frying your appliances.

Is there a way to check on my generator when I’m not home?

Yes! Remote monitors like InfoHub or Mobile Link send alerts to your phone or email. Super handy if you're away often or just like peace of mind.

Where’s the best place to buy accessories that actually fit my generator?

Go with authorized dealers like Engineer Supply, generator supply stores, or the brand’s official site. These places offer the best generator accessories, from transfer switches to maintenance kits, for all kinds of setups—including portable and whole house generator accessories. And if you’re not sure, ask their customer support—most are super helpful.
