   * keeping your bank as charged as possible will let the panels produce the most power for conditions
-In other words, the lower your battery voltage gets the worse the system works.  There are two courses of action to take that will help reduce this effect.

   - **Cycle less deeply** - Instead of cycling to 50% state of charge (12.2v) consider cycling to only 75% SoC (12.4v).
