Turn ON/OFF the main circuit board AC switch.
When turning it off, wait 5 minutes for DC
Voltage to drop to a safe level before removing
the front panel.
Turn the DC Disconnect Switch on/off. (Switch is
available for some models)
When turning it off, wait 5 minutes for DC
Voltage to drop to a safe level before removing
the front panel.
Turn the ON/OFF/P Switch on/off. When turning
it off, wait 5 minutes for DC Voltage to drop to a
safe level before removing the front panel.
Before connecting aluminum wires to terminals:
1. Remove oxide from the exposed wires with emery paper or a
steel wire brush
2. Clean dust with a cloth and Isopropyl alcohol (IPA)
3. Coat wires with a designated antioxidant aluminum wire
grease immediately after cleaning
CAUTION! Connection of oxidized aluminum wires may result
in resistance and high temperatures at contact points.
Improper execution of the following procedure may cause
damage to the unit.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, you are encouraged to try to correct the interference by one or more of the following
measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and the receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party responsible for
compliance may void the user’s authority to operate the equipment.

To minimize electromagnetic interference (EMI), make sure to
minimize the distance between the positive and negative DC cables
Max distance between a combiner
box and any string: 150m / 492ft
Max distance between inverter
and combiner box: 700m / 2297ft

Turn off switches and check
string polarity. Verify 1±0.1V
per optimizer.
Example: 20 optimizers = ~20V
20V
When connecting three or
more H1300 strings to a
combiner box, it is
recommended to use a 30A
fuse for each individual
string. However, be sure to
check local electrical codes
and regulations to
determine the proper fuse
sizing for your specific
installation.
