Frequently Asked Questions

Are Eco-Worthy batteries safe for home use?

+
All Eco-Worthy batteries use LiFePO4 chemistry, one of the safest lithium technologies available. Our Cubix 100 batteries are UL1973 & UL9540A listed and meet CEC standards, 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?

+
We provide up to a 10-year warranty on key battery models, along with U.S.-based support. Our team assists with installation guidance, troubleshooting, and system planning to ensure a smooth experience.
