Frequently Asked Questions

Can this battery system work without solar panels?

Yes - the battery can be charged from the grid and used as a standalone backup power source, though pairing it with solar maximizes savings and energy independence.

How long will it power my home during an outage?

Runtime depends on your energy consumption. Essential loads (lights, fridge, outlets) can typically run for 8-24+ hours depending on battery capacity and usage. Contact us for a personalized estimate.

Is professional installation required?

Yes - battery storage systems must be installed by a licensed electrician or solar professional. Solwel can connect you with certified local installers in the Houston and Dallas areas. Contact us at (346) 432-4228 for a referral.

What warranty comes with this system?

Warranty terms vary by manufacturer. Please refer to the product documentation or contact our team for specific warranty details.
