●● UL 1703.
Answer: Standard for safety, flite plate, Pv modules and panels
●● What PV panels are made from cylindrical silicon ingot.
Answer: monocrystalline
●● Residential Pv systems are limited to no more than 24 two-volt cells
connected in series.
Answer: 48V in total per NEC 690.71
●● Roof mounted systems are mounted on aluminum or stainless steel
rail secured secured into the roof trusses using.
Answer: Lag Bolts
●● Diagnosing a PV problem.
Answer: Stay safe, look at system first, turn things off with disconnects,
then take measurements
,●● PV monitoring systems.
Answer: consists of a device that measures current and voltage on ac
output of the inveter
●● PV source circuits meets PV output circuits.
Answer: in the combiner box
●● The point on the IV curve where the MPPT is maximum.
Answer: is at the third point
●● Current is measured with.
Answer: multimeter with a clamp
●● ARC flashes inverters are equipped with.
Answer: arc fault detection
●● NEC.
Answer: contains which wire to use
●● OSHA.
Answer: Federal agency that establishes and enforces standards of safety
for the workplace
, ●● a restaurant uses 2200WH , 48 V dc, 4.9 PSH, and a Battery
efficiency of 90%, what is the Ah capacity needed?.
Answer: 2200WH/48V = 45.83 AH 45.83AH/.90 = 50.92 50.92/4.9 =
10.39
●● A restaurant uses 2WH and has 10 kWh in storage what can they
operation?.
Answer: They can operate all operations for days. 10 kWh is a lot of
capacity compared to your usage of 2 wh. First convert 10 kWh to
10,000 Wh which is a lot compared to 2 wh. Refer to section 7.4.0 of
your NCCER book for more detail.
●● When you lock out a system you need to use.
Answer: engraving
●● What was a non producing financial incentive for installing pv.
Answer: rebates
●● PV system warranties are for.
Answer: 25 years
●● what amps would cause an installer if shocked not be able to let go.
Answer: over 10MA
