What This Product Is Built For

The 75-Foot Solar Panel Extension Cord is designed to connect your solar panels to your Grid Doctor solar generator while allowing the two components to be placed as far as 75 feet apart.

In a typical setup without an extension cord, the solar panels must remain close to the generator in order to charge it. That usually means placing the generator outdoors next to the panels. With this 75-foot extension cord, you can keep your solar panels outside in the sun while the generator stays indoors, where it can safely power appliances and devices.

This configuration also allows the generator to charge from solar power throughout the day while still being available to use inside your home.

Choosing the Right Option

This 75-Foot Solar Panel Extension Cord is designed specifically for use with Grid Doctor 3300 and Grid Doctor 2200 solar generator systems.

Because the connectors are designed for these systems, this cable is not intended for use with other solar generators or solar setups.

If you own a Grid Doctor 3300 or 2200 and want more flexibility in panel and generator placement while solar charging, this extension cord provides that capability.

How This Fits Into Your Power Plan

During a power outage, a solar generator is most useful when it can charge throughout the day while still powering the appliances and devices inside your home. This extension cord makes that setup possible.

  • Keep solar panels outside where they receive full sunlight
  • Keep the generator indoors where it can power appliances and devices
  • Keep your home secure by routing the flat section of the cable under a closed and locked door

Designed to Work With Your Existing Setup

The 75-Foot Solar Panel Extension Cord is designed to integrate seamlessly with existing Grid Doctor solar generator systems, including setups that include multiple panels or expansion batteries.

The cable connects one solar panel directly to the generator, allowing that panel to remain outside while the generator stays indoors. From there, additional panels can be connected using the shorter daisy-chain cables included with the panels, creating a multi-panel charging setup while maintaining the extended distance between the generator and the panels.

If expansion batteries are connected to the generator, they automatically receive power as the generator charges, so the extension cord supports the entire expanded power system without requiring any additional connections.

Availability & Fulfillment

Why People Choose This Product

Many Grid Doctor owners want the convenience of keeping their generator indoors while still charging it with solar power outside.

Without an extension cable, the generator often has to sit close to the solar panels during charging. The 75-foot extension cord solves that problem, allowing panels to stay in the sun while the generator remains indoors powering devices.

Disclaimers & Notes

Store the cord in a loosely coiled manner in a dry, cool place. Avoid sharp kinking, crushing, or storing in areas of extreme temperature to protect the jacket and internal wiring.

Use only the cables and accessories provided with your Grid Doctor Products or those explicitly approved for use by Grid Doctor. The use of third-party cables or accessories may affect the performance of your Grid Doctor Generator and could pose safety risks. Grid Doctor is not responsible for any loss, damage, or injury resulting from the use of the above mentioned non-approved accessories or cables.

Reliable and effective!

"The other night while my wife and I were sleeping, the power went out (about 1:30 am we figure). When I got up for work at 3:30 am my wife said "no coffee this morning"! I said "wanna bet!" I got my my 3300, plugged in the coffee pot and had a great morning! If you can, get one of these. You won't regret it!"

Disaster preparation

"After surviving the Joplin Tornado in 2011. I decided to get prepared. The Grid Doctor Solar Generator 3300 is an item I have been saving to buy. I feel ready with food, water and basic needs thanks to My Patriot Supply."

Sandra B. (5/5)

Great service!

"We were very impressed with the knowledgeable sales people who answered any questions we had regarding how this cable would benefit and connect to our solar panels for the new generator."

Dawna S. (5/5)

CAP was the best!

"Worked with “Cap" on the phone and he was the best! So helpful and answered every question I had. He called after my order was delivered to check to see if I had more questions. How’s that for Customer Service!"

Marphy B. (5/5)

OMG!! So Cool!

"I first decided to pull the trigger & get the 3300 and was excited about the solar panels. Worked great!! That was all I needed to go all in & get the expansion battery, 2 extra solar panels and the solar extension cable that fits under the door threshold!! I had 700 watts coming into the system and felt like a Star Wars character, "UNLIMITED POWER!!!" I have not used it while charging yet but, if that works as well as everything else, I mean, I will probably get another expansion battery. LOL! But seriously. Somebody stop me!!"

Purchase and use

"My purchasing experience was excellent , but I haven’t used it yet."

Tracy L. (5/5)

Must have

"If you want to run the generator in the house close to appliance and charge it with the panel you really need this extension cord. Lets me charge the generator with the panel on the garage entry and have the generator close to the appliances I want to run. Eliminates a lot of long extension cords inside."

Ron K. (5/5)

Works perfectly, as advertised.

"I have ordered from Patriot Supply over the years. Their service, promptness, and quality of products are outstanding."

Q&A

With an extension cord that long don’t you lose a lot of power going from the panels to the generator?
Thank you for inquiring about the 75-foot extension cord for the 3300 & 2200 solar generators by Grid Doctor. It is made specifically for the Grid Doctor and you will not lose power.
Do i need a separate cord for each panel? If not how many panels does the cord attach to.
One of the 75 ft extension cords attaches to one solar panel, but you can daisy chain the remaining solar panels with the 3 ft provided cords as well.
Does this work with Anker generator and solar panels? Is it waterproof/cold and heat proof? It doesn’t seem too thick?
We do not have information on whether or not this works with other generators and solar panels.
Is there a car-charger cable (or car charger extension cable) available of similar length (50' or longer)?
We currently do not carry these, but our expert recommended checking Amazon for one.
Can this extension cord be used with the car charger that comes with the 3300? (just in case there is a problem with the panels, or a need to charge at night, or on very dark days)
This is the same as the Solar Charging Cable.
