Deep Cycle Battery Bank sizing

Deep Cycle Battery Bank sizing


As we know, many renewable energy (RE) systems incorporate batteries, and so does solar system. Deep cycle batteries can be used in all types of systems including:

  • Photovoltaic or solar panels
  • Wind Power Systems using Wind Turbines
  • Hydroelectric generators
  • Hybrid Renewable Energy Ststems
  • Other power sources


The energy stored in the deep cycle batteries can then be used directly to power DC loads or it can be inverted to power loads. The batteries recommended for RE systems are deep cycle batteries. To ensure you have enough reserve capacity to provide the electricity you need (without running additional generators), invest the time to size your deep cycle battery bank properly. Because of the various conditions affecting battery bank sizing, this process may be one of the more challenging calculations you’ll have to do when planning your RE system.


Before tackling the calculations, start by identifying a few key pieces of information:

  • of electricity usage per day
  • Number of Days of Autonomy
  • Depth of Discharge limit
  • Ambient temperature at battery bank


Electrical Usage


The first thing you’ll need to know is the amount of energy you’ll be consuming per day. It’s worth the time to do a careful evaluation of exactly what loads (appliances, electronics, etc.) you plan to use and for what lengths of time. Keep track of this information on a loads list; you’ll refer to this list often for sizing other components as well. Your final tally should be expressed in Watt-hours (Wh)
