* **rating (or "size")** - this is usually the maximum output the controller can produce (charging + loads).((for technical reasons with PWM this will also be the *input* current limit)) | * **rating (or "size")** - this is usually the maximum output the controller can produce (charging + loads).((for technical reasons with PWM this will also be the *input* current limit)) |
* **12v/24v/48v** - this refers to the nominal voltage of the battery bank it will be charging. | * **12v/24v/48v** - this refers to the nominal voltage of the battery bank it will be charging. |
* **Maximum input voltage** - the highest voltage the controller should //ever// see from the solar array.((it is common to leave ~20% margin)) NOTE: a 50v input max does //not// mean a PWM controller can make efficient use of a 24v panel / 12v battery combination. See how to choose below. | * **Maximum input voltage** - the highest voltage the controller should //ever// see from the solar array.((it is common to leave ~20% margin)) NOTE: a 50v input max does //not// mean a PWM controller can make efficient use of mismatched panel/battery voltages; that requires MPPT.
