    FAQ

    • 1. Can off-grid inverter work without battery?

      +

      Yes, it’s possible to use a solar panel and inverter without a battery. In this setup, the solar panel converts sunlight into DC electricity, which the inverter then converts into AC electricity for immediate use or to feed into the grid.

      However, without a battery, you can’t store excess electricity. This means that when sunlight is insufficient or absent, the system won’t provide power, and direct use of the system may lead to power interruptions if sunlight fluctuates.

    • 2. How long do off-grid batteries last?

      +

      Typically, Most solar batteries on the market today last between 5 and 15 years.

      ROYPOW off-grid batteries support up to 20 years of design life and over 6,000 times of cycle life. Treating the battery right with proper care and maintenance will ensure a battery will reach its optimal lifespan or even further.

    • 3. How many batteries do I need for off-grid solar?

      +

      Before you can determine how many solar batteries are required to power your home, you need to consider a few key factors:

      Time (hours): The number of hours you plan to rely on stored energy per day.

      Electricity demand (kW): The total power consumption of all the appliances and systems you intend to run during those hours.

      Battery capacity (kWh): Typically, a standard solar battery has a capacity of about 10 kilowatt-hours (kWh).

      With these figures in hand, calculate the total kilowatt-hour (kWh) capacity needed by multiplying the electricity demand of your appliances by the hours they’ll be in use. This will give you the required storage capacity. Then, assess how many batteries are needed to meet this requirement based on their usable capacity.

    • 4. What is the best battery for off-grid solar system?

      +

      The best batteries for off-grid solar systems are lithium-ion and LiFePO4. Both outperform other types in off-grid applications, offering faster charging, superior performance, longer lifespan, zero maintenance, higher safety, and lower environmental impact.
