What device decides when to stop charging the battery
bank?
Inverter
Charge controller
Micro-inverters
Transformer
What device decides when to disconnect the battery bank
from the loads?
Charge controller

AC-DC disconnect
Solar pathfinder
What piece of equipment protects the batteries from being overcharged or undercharged by the array?
Inverter
Transfer switch
Charge controller
None of the above
What is “autonomy”?
The concept of electric autos powering the economy with solar.
The capacity to make an informed, un-coerced decision.
Another name for a self-driving car.
How long a battery system will provide the necessary power before needing to be recharged.
What type of controller is needed if you have a stand-alone PV system and a wind-turbine?
Hybrid
Non-synchronous
Asynchronous
Series charging
Setpoints are used if you have different types of batteries than what a controller is preset for.
What are “setpoints”?
Points that are set in order
The desired or target value for an essential variable, or process value of a system.

None of the above
A self-regulating PV system does not need a charge
controller.
Why not?
It's a system that has less than 24 batteries.
It self regulates without the need for a charge controller.
It's a system that has 500 watts or less.
All of the above
What happens if a charge controller is far from a battery bank and no compensation is made?
Nothing
The batteries could explode.
The batteries could under-charge.
The batteries could over-charge.
If a battery bank is in a colder or hotter location than the controller, what effect does this have?
Batteries could over or under charge
Batteries could freeze or boil over
The solar array would not provide sufficient power to charge.
Nothing happens
A certain charge controller says it does MPPT.
What is that?
Multi-preset power testing
Maximum power point tracking on an inverter.
Maximum panel power test
Maximum power point tracking on a solar panel.
