Intermatic Compressor Defender
Compressor Defender™ vs typical surge protector:
Defender protects 3 ways: Undervoltage (brownout), Surge, and Short Cyle
Resource: Compare AG3000 with Compressor Defender
NEC 2020 (Article 230.67) States that all residential dwelling units shall be provided with a Surge Protective device ... applies to New and replaced service equipment supplying dwellings are now required to be protected by listed.

Type 1 or Type 2 Surge Protective Devices. The compressor defender is typically used for HVAC installation, while AG3000 is installed at the service panel (breaker box).
Note that the closer a surge protection device is to load, the better it protects. Multiple surge on same circuit gives greater protection: so AG3000 and Compresser defender can both be installed.

How do brownouts impact the average U.S. Household?
44 percent of homes experience brownout or low voltage event each year
12 percent must replace major appliance.

How to identify brown-out... Incandescent light bulbs dim.
You can be on a dual transformer from power company that causes voltage drop each time compressor turns on.
Or overtaxed grid lowers power to certain areas to keep grid online during very hot days
Ice storm causes downed power lines that can cause disturbances.
Power company transformer can malfunction

Appliances and electronics – including air conditioners, pool equipment, pumps, and power vent and hybrid water heaters etc - are susceptible to damage from low voltage if not protected.

What goes unnoticed after a brownout is the wear on appliance motors.
Low voltage causes motors to get hot, reducing life of motor
Loss in power deteriorates the chemical makeup of refrigerants.
Momentary power interruptions that last five minutes or less can be more costly than sustained interruptions.

homeowners need to protect appliances such as air conditioners, furnaces, refrigerators and washing machines to avoid costly damages.
expensive systems like central air conditioning units, which would cost thousands of dollars to replace, sit completely unprotected from surges, brownouts and blackouts,”
86 percent of homeowners are at risk of incurring significant replacement costs because their air conditioning units are not protected from power surges

voltage monitor Voltage monitor
The problem of low voltage does not affect resistance loads like, light bubs or electric water heater, except to make them burn at dimmer capacity... low voltage does affect inductive loads like contactors, relays, motors, pumps, HVAC causing problems such as lower rotation speed on motor, causing higher temperatures, and burning out the motor.

Voltage monitor Protect motors and equipment from low voltage.
Adjustable voltage range
Caution: select monitor voltage to match incoming Line voltage
Select amp rating of contactor to match amp rarting of Load
Select matching contactor voltage and coil voltage range
Undervoltage on contactor coil will cause chattering, Overvoltage on coil will melt coil.

Surge protection
Compressor Defender is Type 2
AG3000 shown below is Type 1 Type 2
Type 1 permanently connected, hard wired SPD surge protection device installed before or after main breaker box or main disconnect. Type 1 is located between secondary on service transformer and line side of service entrance (main breaker box or main disconnect). Or anywhere on load side of service entrance including at equipment location (HVAC disconnect etc).
Type 2 is installed at the main disconnect or at breaker box or at the equipment location (HVAC disconnect etc), May or may not be connected to overcurrent protection (connected to circuit breaker or disconnect) depending on listing..., read instruction manual
Type 3 is used in addition to Type 1 or 2, especially when location is farther away. Install as surge outlet or surge protection strip or surge supressor at your computer, or at any location farther than 50 feet away from main surge protection. Type 3 is connected to ground and not to overcurrent protection.

Surge protection that is rated Type 1 is considered Type1 Type2 and can be installed anywhere within the distribution system. Multiple surge protectors can be installed, and will protect better as distances increase... because surge, such as lightning, can enter wires anywhere.

Bond solar panel to ground rod Correct grounding can help prevent surge damage (but cannot protect from brownouts or low voltage events)
Ground wire
All phone, satellite, pool equipment, solar systems and electric pnaels must be grounded. Check local electric codes.
What does this mean? Drive ground rod 8-10 feet into soil. Bond #6-8 bare copper wire to ground rod and to solar panels and pipes on roof.
Do NOT ground electric system to water pipes. Ground must be connected to ground rod. Stray current corrosion can cause pipes to deteriorate. Uncertain bond to ground because of plastic pipes.

Bonding lugs
Bond all ground wires together to help prevent surge & lightning damage
Bonding all grounds together will help prevent damage from lightning strikes beyond 100' away...
Strong lightning strikes within 100 feet must be handled by lightning rod
Local code requires bonding: this includes all ground rods for satellite, TV, phone, solar, electric panel, subpanels (within 100 feet) etc must be connected together and bonded to main electric panel ground rod driven into soil at correct depth to meet local code. Consult local electrician.
Codes for grounding depth vary: loose rocky dry soils are less conductive than dense wet soils
No system other than lightning rods will protect against direct lightning strike or strike within 100 feet.
Move indoors and do not stay on roof, or move metal ladders, or touch anything made of metal when lightning is within 1 mile or can be heard or seen.
