The best panel match for a PWM controller:

The best solar panel matching  for a PWM solar controller is a panel with a voltage that is just sufficiently above that required for charging the battery and taking temperature into account, typically, a panel with a Vmp (maximum power voltage) of around 18V to charge a 12V battery.  These are frequently referred to as a 12V panel even though they have a Vmp of around 18V.

Choosing the right solar controller/regulator

The PWM solar controller is a good low-cost option:

• for smaller off grid solar systems

• where the efficiency of the system is not critical, e.g trickle charging.

• for solar panels with a maximum power voltage (Vmp) of up to 18V for charging a 12V battery (36V for 24V battery, etc).  

SYSTEM CONNECTION:

1.Connect the battery to the charge regulator - plus and minus.

2.Connect the photovoltaic module to the regulator - plus and minus.

3. Connect the consumer to the charge regulator - plus and minus.
