DETAILED ANSWERS WITH RATIONALES || 100%
GUARANTEED PASS <RECENT VERSION>
Proportional Relationship ......ANSWER........When current goes up
and resistance constant, then voltage also increases.
when measuring dc current with a clamp on ammeter, make sure
that you are either ......ANSWER........clamping on the negative or
the positive but not both
With PV and batteries, In series connections
......ANSWER........Increases voltage, positive to negative and
increase voltage
,age 2 of 47
In parallel ......ANSWER........All of the positives are connected to
one place and all of the negatives together. The current
increases
solar power measured in ......ANSWER........watts per square
meter
anti - islanding ......ANSWER........the inverter cannot operate
alone as an island of power. The grid tied PV system have to be
able to disconnect from the grid whenever the grid is down or
not within specifications.
Main components of a DC coupled system, the most common and
simple off grid systems. ......ANSWER........Solar modules, charge
controller, battery, inverter
Battery inverters ......ANSWER........Create voltage
,age 3 of 47
Grid Tied Inverters ......ANSWER........Work when there is no
utility
Main components of an AC coupled system, complicated and less
common system ......ANSWER........solar modules, grid tied
inverter, off grid inverter/charger, batteries
Voc = ......ANSWER........OPEN CIRCUIT VOLTAGE
ISC = ......ANSWER........SHORT CIRCUIT CURRENT
Vmp = ......ANSWER........MAXIMUM POWER VOLTAGE
Imp = ......ANSWER........MAXIMUM POWER CURRENT
The inverter size is based upon the ......ANSWER........size of the
PV array
, age 4 of 47
Grid Tied Battery- Backup (GTBB) PV systems can
......ANSWER........operate as grid tied systems and off grid
systems
What are loads? ......ANSWER........Devices that consume
electricity
Direct, Direct Coupled PV System ......ANSWER........The simplest
type of PV system, the only components are PV and the load.
A self regulating PV system ......ANSWER........is a stand alone PV
system without a charge controller, designed so that it will not
charge over 3% battery capacity in an hour
Building Integrated PV or BIPV ......ANSWER........a part of the
building and is not as efficient as regular PV because it is hotter
