Battery
Tesla Powerwall and Huawei Backup Box when the grid drops
Storage without a backup gateway is a cheaper bill. Storage with a Backup Box is a house that still cools, cooks, and connects.
A battery that only shaves the evening tariff is a financial product. A battery that keeps the house alive when the street goes dark is a resilience product. On the Algarve you usually want both, and they are not the same install.
Powerwall as the store
Tesla Powerwall takes surplus from the array and gives it back after sunset. For most family homes that is the daily rhythm: cool through the afternoon on sunshine, run the evening on stored energy, sleep on a quiet grid.
Backup Box as the switch
The Huawei Backup Box is the piece that islands selected circuits when the grid fails. Without it, many solar-and-battery systems still shut down — inverters are designed not to back-feed a dead street. With it, the house can keep refrigeration, a chosen indoor unit, and communications.
We sit with owners and mark the consumer unit together. Trying to back up the whole villa including the pool pump is how you empty the battery in forty minutes.
Who this is for
- Houses used as primary homes with office or medical loads
- Hospitality kitchens and guest-wing cooling
- Rural plots at the end of a brittle feeder
