Solar PV Installation and Batteries Exam Questions and Answers Latest Update 2025/2026
what type of batteries are used - Answers valve regulated lead-acid
what is the additional safety margin on Fuses and AC Breakers - Answers 125% on Fuses and
AC Breakers
ISC - Answers Short Circuit Current
Voc - Answers Open Circuit Voltage
Inverter output designs - Answers Sine Wave and Modified Sine Wave
Kwh to Watt hours - Answers x 1000 = Watt Hours
Electrolyte and how to use it - Answers liquid or gel in batteries that contains ions. If frozen in a
battery do Not charge.
Flooded Open-Vented Batteries need what - Answers Equalization. Short Period over charging of
batteries to refresh cell capacity.
Parallel battery connections should be limited to how many strings - Answers 3-4 strings
Soiling - Answers accumulation of dust and dirt on an array that shades and reduces electrical
output.
Deep Cycle Lead-Acid batteries can be discharged how much - Answers 80% most PV systems
use this type of battery
Charge Controller - Answers controls the charging rate and/or state of charge for batteries. Also
can monitor system performance and provide system protection.
How do batteryless PV Systems connect - Answers In Parallel through the utility Service to
panel.
AC current losses vs DC current losses using the same wire - Answers AC loses a lot less, more
efficient
Closed Circuit Voltage vs Open Circuit Voltage - Answers =?
rated Voltage in PV source circuit should be which voltage - Answers Closed-Circuit Voltage
Absorption Coefficient - Answers Amount of Voltage, Current, and power output of a solar cell
changes due to a change in cell temperature
Multi Wire Branch Circuit - Answers each individual wire is seperate and not combined in the
same sleeve/conduit which is dangerous.
