Building Blocks of Solar Part 8-Battery Maintenance

Battery Maintenance

Today we will discuss battery maintenance.  It is one of the big differences between a grid tied and an off grid system.  A grid tied system just sits there and generates electricity either for your home use or to be fed back onto the grid.  The battery bank in an off grid system adds a whole new level of complexity.  We have previously discussed the types of batteries but for the purpose of this conversation I am going to focus on lead acid batteries.  Here are the primary topics for discussion:

  1. The Chemistry behind discharging and recharging batteries
  2. Standard Maintenance
  3. Charging Cycles
  4. How to measure Specific Gravity and Equalization(overcharging)

After listening to the podcast if you have questions please email them to me at or add them to the comment section of the blog.  Additionally you can go to our Facebook page to get more information or to ask questions.
