 Many smaller units have quite restrictive solar input limits.
-  * **voltage** - 24Voc is a common voltage limit, effectively limiting one to [[electrical:solar:panels#panel_voltage|12v nominal]] panels. **Input voltage limits must not be exceeded**.
+  * **voltage** - 24Voc is a common voltage limit, effectively limiting one to [[electrical:solar:panels#panel_voltage|12v nominal]] panels. **Input voltage limits must not be exceeded**.  Note:  some very large units have high input //minimums//, like 50v.
   * **current** limit - 3A is a common input current limit on smaller, less-expensive units.  8A is a common limit on larger units.
     * With PWM controllers the max power harvestable will be 3A x [internal battery voltage], which can be as low as 9v.  9v x 3A 27w.  **PWM input current limits must not be exceeded**
