Equipment Required For Off Grid Systems

Equipment Required For Off Grid Systems

An off grid solar kit requires more than a few panels that soak up the sun.

Here are the essential components of a solar power system for your home:

Battery Storage

Devices manage the flow of energy from the solar panels to the battery and they ensure that the battery is charged correctly without any overcharges occurring.

Solar Inverters

Inverters (AC) or MPPT solar charge controllers (DC) – these charge controllers are different from the battery inverters because while they control the battery charge, the input voltage from the solar panels needs to be at least 30% over the voltage of the battery.

Battery Bank

The battery bank is where all extra power and energy is stored for use during nighttime hours or for those days that are overcast.

Solar Panels

The panels are installed onto the roof of the home or placed around the home to ensure the correct wattage. These little cell-filled squares are joined together to harness the power of the sun.

Generator (Optional)

A generator is optional. If you want to use a generator when running a solar panel system, then you can. The devices provide a secondary source when power failure strikes, however, they require fuel to run.

Off Grid Batteries

  • Lead-Acid – the lead-acid battery there are different battery options and can be the more cost-effective option. Necessary maintenance is absolutely required to ensure that this battery is working properly and supplying the home with the right amount of juice to avoid power failure.
  • Lithium-Ion batteries are more expensive but a lot more convenient as they do not need to be charged to be used and they can easily be stored without ventilation. They require no maintenance at all and are desired for a pre-set number of charging
