This inverter 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, the user is encouraged to try to correct the interference by one or more of the following measures: a) Reorient or relocate the receiving antenna;
b) Increase the separation between the equipment and receiver; c) Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected; d) Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesidered operation.
Electrical warnings
2.
Wiring methods used should be in accordance with the National Electric Code, ANSI/NFPA 70 (NEC), Canadian Electric Code (CEC), and/or
other local codes and regulations.
The PV source conductors must be Listed PV wire per NEC 690.35.
PV output conductors must consist of sheathed (jacketed) multi-conductor cables or installed in an approved raceway and must be isolated
from the enclosure and system grounding, as required by NEC 690.35 and is the responsibility of the installer.
An external DC switch must be used if not integrated in the inverter; all -S models have an integrated DC switch.
AC output overcurrent protection is not provided; it is the responsibility of the end user to provide protection for the AC output circuit.
All photovoltaic source and output circuit conductors shall have disconnects complying with the NEC, Section 690, Part III.
To reduce the risk of fire, connect only to a circuit provided with 15A maximum branch circuit overcurrent protection in accordance with the
NEC (ANSI/NFPA 70). See Maximum AC OCPD requirement in section 16 on next page.
To prevent electrical hazards, all the connections must be carried out with the disconnect switch downstream of the inverter
(grid side) open and locked out.

The inverter cover is equipped with fixed hinges and is not intended
to be removed from the chassis.
Wiring box cover 06 must be removed before opening the inverter cover 04.
Loosen the four captive screws to remove the wiring box cover 06.
Loosen the four captive screws on the inverter front cover 04.
Using light pressure, pull out and up on the cover so it rotates in an upward
arc to its rest position.
Remove the protective film located on the inverter front cover display 01.
When connections are complete, close covers and tighten the captive
screws with at least 2.0Nm (17.7in-lbs) torque to maintain waterproof
sealing.
7.
The inverter uses pressure type terminal blocks for connection of all conductors.
Acceptable wire size range is from 12 AWG to 6 AWG; refer to local codes for appropriate
wire size; use only copper wire rated at least 90C.
To plug the input cables into the inverter it is necessary to replace the knockout plugs 18
and 19 with an EMT FITTING 3/4 (thread 14 NPSM).
All connection operations must be carried out with the DC disconnect switch
07 turned to the OFF position and locked out AND the external AC disconnect
switch downstream of the inverter (grid side) open and locked out!

Set the grid/country standard using the two rotary switches found on the main board in the inverter prior to connecting the inverter to the
distribution grid. Before turning the rotary switches confirm the inverter is switched OFF!
Refer to selections below for the appropriate choice of grid parameters.
Default setting 0 / 0 means no grid standard is selected and display language is English.
(Set Country message will appear on the inverter display).
Turn dials of two rotary switches a09 to program the selected grid settings.

Settings become fixed after 24 hours of operation (the inverter does not need to be connected to the
grid, but only needs DC power to count operation time).

In order to configure the ADDRESS settings (section 13) prior to grid connection, the inverter display only needs DC power to use the menus.
DO NOT connect the AC power (grid side) at this time! With only the array connected, set the inverters DC disconnect switch to ON.
GREEN POWER LED will flash and YELLOW ALARM LED will be steady. The message Missing Grid will display in area b10.
Press ESC to open the menus. Use the DOWN key to scroll to SETTINGS, and press ENTER. The SETTINGS menu requires an access password.
Upon selecting SETTINGS the password screen will open; the default password is 0000.
Pressing ENTER four times loads four zeroes on the display and opens the submenu.

Area b10 has two visible text lines and the UP and DOWN keys are used to scroll through the menu items.
Arrow > on the left side of the display highlights the current selection.
Press UP or DOWN keys to move the arrow to the desired selection and press ENTER to open the associated submenu.
To return to the preceding menu, press the ESC key.

Scroll to Address and press ENTER to open the submenu.
Address values are assigned manually using any value in the range 2 to 63.
Press UP and DOWN keys to scroll through numbers and press ENTER to select, ESC to cancel.
Turn DC disconnect switch 07 to OFF in order to save the changes.
The procedure for start up is as follows:
Initializing . . .
Waiting Sun . . . .
Turn DC disconnect switch 07 to ON position.
Please wait
If there are two separate external disconnect switches (one for DC and the other for AC),
first close the AC disconnect switch and then the DC disconnect switch. There is no order of priority for opening the disconnect switches.
When the inverter has power, the first check performed relates to input voltage:
If DC input voltage is lower than Vstart voltage (voltage required to begin the inverters grid connection) icon b14 remains off and the
Waiting sun message is displayed in area b10.
If DC input voltage is higher than Vstart voltage icon b14 is displayed and inverter goes to next stage . Voltage levels and input current
are displayed in the b15 and b16 fields.
The inverter performs a control of grid parameters. Icon b22 represents grid distribution and can display the following states:
not present indicates AC voltage is absent, flashing indicates AC voltage is present but outside the parameters of the country of installation,
steady ON - indicates AC voltage is present and within the parameters of the country of installation; this status starts grid connection sequence.
If the input voltage and the grid voltage are within the inverter operating intervals, connection to the grid will begin.
Icon b21 represents an electrical plug that is connected when the inverter is connected to the grid and a disconnected when not connected.
When the connection sequence is complete, the inverter indicates its correct operation by making a sound and by the green LED coming on steady
on the LED panel. If the inverter signals any errors/warnings the messages and their codes will be indicated on the display.
Refer to full technical manual on the website for Error and Warning Codes.
