I have a customer who is concerned about surge protection for his appliances and computer when he get's his new generac generator installed. He already has a UPS on his computer but no other protection. What do y'all believe to be the best cost effective solutions and do you believe power spikes are real a concern? He will be getting the 16kw generac to handle his small home that has a 2 ton AC and gas furnace. Thanks in advance for your feedback.

Is this a concern about potential spikes from the generator?

The generator can not produce the same surges as utility power, but the best Type 1/2 Surge Protector for residential/light commercial is the Eaton SP1-240S

My vote would be for the Midnite Solar SPD products.

I cannot find any specifications on that SPD, which is concerning because I have no idea what the level of protection that device provides.

The Eaton SP1-240S provides 50,000 Amps of surge protection per phase, many big box stores ones are only 10,000 Amps. The Eaton SP1-240S has a 20,000 Amp discharge current rating, and has a short circuit current rating of 200,000 Amps.

With surge protection devices it is very important to compare apples to apples! There are a lot on the market that are complete junk.

Midnite is good stuff, I know the company.

Still, I wonder exactly what he is trying to protect against. I wonder if he knows. What kind of surge, caused by what, and what do we propose to do about it?

Installed the Siemens First Surge in all of the panels for whole house protection from the power company or close proximity lighting strikes. With the prior loss of a few electronics, installing a whole house surge protector is far cheaper.

Surge protection has many different levels......here's what I have for my house:

#1 SPD on the transformer can on the utility pole..installed by POCO as SOP for the last few years.

#2 SPD mounted under the meter, also installed by POCO at my request something like this... [url]https://www.amazon.com/Leviton-50240-MSA-Secondary-Arrestor-Protective/dp/B0019F6X3I[/url]

#3 number of panel SPD's (whole house) Leviton 51120-1 at the main and 5 Midnite Solar AC SPD's at each sub-panel

#4 control circuit SPD protection for my Generac [url]http://pspproducts.byethost11.com/control-wiring-surge-protector/?i=1[/url]

#5 DC SPD's at each solar array and each inverter... total of 7 all together.

#6 point of use SPD's at each critical use site ie entertainment center, desktop computer, workshop tools, any sensitive electronics

Most people think it is overkill but after losing thousands to side strikes over the years I know better. Since I installed the above no losses but keeping my fingers crossed.

I consider SPD's anywhere as cheap insurance. Every appliance in your house now has a electronic board. Those boards blow out in a heartbeat and they are not cheap to replace.

Dan, where can you buy the PSP surge protector for the control wiring? I’ve looked and can’t seem to find it anywhere.

I bought it directly from the manufacturer...PSP Products. That was a few years ago, they may have distributor near you by now.
