Battery Repair & Installation

Home battery work — Tesla Powerwall and equivalent storage. Diagnosis and repair on systems you already own, and installation sized to what you actually use.

Top Four Reasons Batteries Fail

  • The Gateway Fails More Often Than the BatteryOn most home systems the cells are fine and the gateway, a breaker or the communication link is what actually broke. The battery gets blamed for it.
  • Backup Circuits Were Never Set Up RightA battery only backs up the circuits it was wired to. Plenty of Texas homeowners found out during a February outage that the fridge was never on the backup panel.
  • Heat and Garage PlacementBatteries have a thermal operating range and an uninsulated Texas garage in August sits at the edge of it. Sustained heat costs you both capacity and lifespan.
  • Firmware and Connectivity DriftA new router, a changed wifi password or a stalled firmware update will take a battery off the network. It keeps storing power and stops telling you anything about it.

Top Four Solutions to This Problem

  • Test the Whole Chain, Not Just the BatteryCells, gateway, breakers, transfer switch and comms. We find which link failed before anyone quotes you a new battery.
  • Fix What Your Backup Panel Actually CoversWe go through the circuits with you and move the ones that matter, so an outage protects the fridge, the well pump and the room you sleep in.
  • Repair and Reconfigure Before ReplacingGateways, breakers and wiring are serviceable and firmware is recoverable. Replacement is the last option, not the opening quote.
  • Install and Commission It ProperlyNew batteries get sized to your real usage, placed where the temperature will not cook them, permitted, and commissioned so the backup works the first time you need it.
