From Joanne Myers

I searched for several days to find a local store which carried the connectors that were needed for the panels that I bought 5 years ago. I was very happy to find exactly what I needed at your site . The price was reasonable and delivery was prompt. I was able to complete my project . Thanks for being there.

Solar Cable connectors

Came in as described. Not hooked up yet just received them but have had good luck with past cables.

Great stuff

I live in a cabin tent all summer. Last year I added an Eco-Worthy 100 amp battery to my solar generator system. It works so well I’m adding a second battery and two solar panels to the system. I don’t think I will have to run the gas generator at all this year. Eco-Worthy is so economical and easy to set up I recommend it to anyone looking into solar power.

Super easy

Connectors finished the addition of panels to the hybrid greenhouse project

i have to use a parallel connection to be able to combine multiple panels to charge 1 battery pack, and these connectors do the trick… almost completely foolproof, they make it where the male connectors go together, and the female connectors go together, and ne'er the twain shall meet… they work so well, i have ordered another set… using these to combine 2 of my eco-worthy 195w bifacial panels is just what the battpack 3 requires, and they cut the charging time almost in half… and, yes, time is definitely money!…

Good product.

Good product. Works as it should. Poor communication from eco-worthy. My credit card was compromised with this purchase.

Exxcellent Service

order delivered promptly - very pleased with the product - will be ordering other items in the future - steep learning curve but will eventually be off grid.

Impressive

I was very happy to receive my y connectors. Appear to be high quality material and well made. I am looking forward to installing them on my first string of my solar project.

I am not at home at the moment I haven't connected any of it I'll gladly leave a review later

System Complete

Great day! Today I received my 6 Eco-worthy bi-facial solar panels I've been waiting on and Good Friday I'll be attaching to my Eco-worthy Dual Axis Tracker previously purchased and my Eco-worthy system will be complete! Stay tuned for my over all review.

Looks great!

I got these to use in my sailboat and can’t wait to head south and hook them up!

Solar

Worked perfect easily K’NEX and disconnects

Owner

👍👍

These connectors sure made it easy to connect my 3 100 w panels on my camper!

Excellent option

With the "Y" connectors they provide an excellent sustainable connection, plus their bendability enabled me to have four 100 watt solar panels over the cockpit of my sailboat (serving as a bimini too)!

good quality and fast delivery

Frequently Asked Questions

Are Eco-Worthy batteries safe for home use?

All Eco-Worthy Batteries Built with premium Grade A LiFePO4 cells, one of the safest lithium technologies available. Built-in BMS protection prevents overcharge, overheating, and short circuits—making it ideal for residential energy storage.

Will it work with my inverter/solar system?

Yes. Our batteries are designed to be widely compatible with most 48V inverters and solar systems used in U.S. homes. For best performance, we recommend checking your inverter’s communication protocol or contacting our support team before purchase.

How much power do I actually need for my home?

It depends on your usage: 5–10 kWh → essentials (fridge, lights, WiFi); 10–20 kWh → partial home backup; 20 kWh+ → whole-home coverage; Our systems are scalable, so you can start small and expand anytime.

Can I expand the system later?

Absolutely. Eco-Worthy batteries support parallel expansion, allowing you to increase capacity as your energy needs grow—without replacing your existing system.

What kind of warranty and support do you offer?
