How many hours will my TAICO battery last in a power cut?

Estimate the backup hours of a TAICO battery, understand why the real figure drifts, and measure it during actual cuts.

  • Usable energy is the capacity times the share you allow the battery to use, minus inverter losses.
  • The inverter’s own consumption matters a lot at night, when the house draws little.
  • Measured hours during real cuts beat any estimate, and they show you when the battery starts to age.

    Simulation of a sunny day for a house with 5 kWp of panels, a 10 kWh battery, a car that needs 10 kWh and a water heater. The energy delivered to each appliance is the same in both scenarios; only the timing changes. Your figures depend on your system, your tariff and the weather.
