Solar Charge Controllers
- They allow PV to operate at its maximum power point voltage
- Controller drops this down to battery voltage
- Current is boosted by doing this
- So panels deliver full power to battery
- Panel voltage doesn’t need to match battery voltage
- Can use high voltage string configurations
- Smaller cable can be used
- PV can be sited further from battery
- Better for larger systems (>200Wp)
- 60 cell panels are better value than 36 cell 12V panels so the extra power delivered can justify extra cost of the controller even for 12V systems

Morningstar Communication Adaptors
Morningstar’s PC MeterBus Adapter converts a controller’s MeterBus RJ-11 to a standard RS-232 serial connector for connection to a PC or other equipment. The MSC may be used with any Morningstar controller or inverter equipped with a meter connection that does not also already have a RS-232 port. Communications link enables monitoring and logging of data as well as customizing of set points.

MPPT Charge Controllers
These are needed for use with larger 60 cell PV panels in order to match the PV output voltage with battery voltage.
They allow a PV array to deliver up to 30% more power to a battery than it would if it were connected directly to the battery.
The current from PV modules varies with sunlight levels but is fairly constant over a wide range of voltages. This means they can operate at higher voltages than the voltage of the battery bank which they are charging.
Advantages
PWM Charge Controllers
These work by gradually reducing (or tapering) the flow of energy into the battery as a full charge is reached so achieving a more complete charge. Very fast solid state switching technology is used for this, known as pulse width modulated (PWM) control.
