(1)to one of the .35” (9mm) diameter holes marked “ground”
using 5/16” stainless steel hardware. Wrap conductor
around bolt. Tighten the screws with adequate torque
(usually 132 in-lb). Avoid direct contact of copper ground
conductor to aluminum frame.
(2)to a ground lug (manufacturer:ILSCO,model:GBL-4DBT).
Tighten the screws with adequate torque (usually 62
in-lb). Use #10-32 stainless steel hardware to attach the
lug to the module frame by the torque of 40 in-lb. A
stainless steel star washer, positioned between the lug
and the anodized surface of the frame, must be employed
to break through the anodized layer of the frame
extrusion and electrically connect the ground lug to the
conducting aluminum frame material.
As a general rule, avoid direct contact of copper or copper
alloy ground conductors with the aluminum module frame.
All ground bond securing hardware in contact with either the
aluminum module frame and / or copper or copper alloy
ground conductors must be stainless steel.
9. BLOCKING DIODES
In systems utilizing a battery, blocking diodes are typically
placed between the battery and PV module output to
prevent battery from discharging at night.
KDxxxGX-LPx
series modules are made of polycrystalline cells with high
electrical “back flow” resistance to nighttime battery
discharging. As a result,
KDxxxGX-LPx series modules do
not contain a blocking diode when shipped from the factory.
Most PV charge regulators and inverters incorporate
nighttime disconnect feature.
10. BYPASS DIODES
Partial shading of an individual module in a source circuit
string (i.e. two or more modules connected in series) can
cause a reverse voltage across the shaded cells within the
module. Module output current is then forced through the
shaded area by the remaining illuminated cells and other
PV modules in series with the partially shaded module(s).
The current forced through the shaded cells within PV
module (or modules) causes additional module heating and
severe loss of power. All
KDxxxGX-LPx series modules are
supplied with factory installed (non user serviceable)
bypass diodes.
The purpose of bypass diodes is to provide a low-resistance
current path around the shaded cells, thereby minimizing
PV module heating and array current losses.
PV modules employ bypass diodes that have:
・ Rated Average Forward Current [I
F(AV)
] Above
maximum system current at highest PV module
operating temperature.
・ Rated Repetitive Peak Reverse Voltage [V
RRM
] Above
maximum system voltage at lowest PV module
operating temperature.
11. MAINTENANCE
KDxxxGX-LPx series modules are designed for long life
and require very little maintenance. Under most weather
conditions, normal rainfall is sufficient to keep the module
glass surface clean. If dirt build-up becomes excessive,
clean the glass surface only with a soft cloth using mild
detergent and water. USE CAUTION WHEN CLEANING
THE BACK SURFACE OF PV MODULE TO AVOID
PENETRATING BACK SHEET. PV modules that are
mounted flat (0°tilt angle) should be cleaned more often,
as they will not "self clean" as effectively as modules
mounted at a 15°tilt or greater. Once a year, check the
general condition of the wiring and check to be sure that
mounting hardware is tight. Loose connections may result
in a damaged module or array.
