Home battery backup for existing Houston solar
Most grid-tied residential solar systems shut down when the grid loses power. That protects line workers and does not necessarily mean your solar system is broken. If you want power during an outage, the system needs compatible backup equipment that can safely separate the home from the grid. Green Star Restoration adds batteries to existing residential solar systems in Houston and surrounding cities. We begin with the equipment you already have and the loads you want to keep running, rather than assuming any battery will work with any inverter.
Plan around what matters at home
Start with a list of essentials such as refrigeration, lighting, internet equipment and selected outlets. Larger appliances have different power requirements, and the length of an outage matters as much as the list of devices. A battery has both energy capacity and a power-delivery limit, so whole-home backup cannot be promised from a product name alone. Tell us what you want supported and any priorities that affect the plan. Backup equipment is not a guarantee of uninterrupted medical support; follow device-provider emergency guidance and keep an appropriate independent contingency plan for critical needs.
Book a Houston-area solar service visit
Choose an available visit tomorrow or the following day, in Central Time. A technician checks your system and provides a written quote before any work.
Compatibility with an existing system
Battery options depend on the inverter, electrical setup, available space, communications and the backup configuration. Some solutions connect on the AC side; others pair with specific inverter equipment. The technician checks what fits before recommending a path. Green Star Restoration is SolarEdge certified and services existing systems from other installers too. If your solar monitoring is offline or production is already low, we can identify that service issue alongside the backup assessment. A battery does not repair a failed panel or inverter merely by being added, so the condition of the existing system matters.
Outage operation and everyday use
Stored energy may support selected circuits during an outage when the installation includes the required switching and control equipment. Available runtime depends on the chosen battery, the loads running, the starting charge and whether the system can recharge under the conditions. Everyday storage use also depends on settings and the electricity plan. We do not promise bill elimination, a savings amount or a particular outage duration. Your written quote explains the proposed work and backup scope, so you can evaluate the equipment for your home rather than relying on a general claim about batteries.
Prepare for a backup assessment
Have the inverter brand, monitoring information and installation paperwork available if possible. Keep passwords private and do not open equipment to retrieve a model number. Tell us whether the system is owned, leased or under a PPA, because authorization may be needed from the system owner. Share the essentials you want backed up and any existing equipment concerns. Online booking offers available visits tomorrow and the following day in Central Time. For a later date, leave your details and we'll reach out within 1 business day.
