What customers across Hawaii say

★★★★★

Generator transfer switch installed properly. The last guy had wired an extension cord setup that could have backfed the line.

Ken A.
★★★★★

Smart switches through the whole house. They added neutrals where the boxes didn't have them instead of telling me it couldn't be done.

Jodi N.
★★★★★

Level 2 charger in a detached carport, about eighty feet from the panel. Quoted the run honestly up front.

Frequently asked questions

What size generator do I need in Hawaii?
It depends what you want running. A critical loads setup covering fridge, lights, fans and a well pump is far cheaper than whole home coverage. We size it from a load calculation.
Do I need a transfer switch in Hawaii?
Yes. Running a generator through an extension cord or a backfed dryer outlet can energise the utility line and is genuinely dangerous. A transfer switch isolates you properly.
Automatic or manual transfer in Hawaii?
Automatic starts and switches on its own within seconds, which matters if you are away or have medical equipment. Manual costs less and is fine if someone is usually home.
How long does generator installation take in Hawaii?
A manual interlock or inlet box is often a single day. A standby unit with an automatic transfer switch typically takes one to two days plus inspection.
Can you service a generator already installed in Hawaii?
Yes, including transfer switch testing, load testing and fixing installs that were not done correctly the first time.
Where does the generator go on a Hawaii property?
On a level pad, clear of windows and vents, with the manufacturer's clearances respected. We will walk the property and show you the options.
