NOTE 1: DC array wiring and ground terminals are spring pressure type and accommodate a wire size
range of 16-6 AWG. AC output terminals are spring pressure type and accommodate a wire size range of
14-4 AWG. NOTE 2: AC ground terminals are spring pressure type and accept 16-4 AWG wire.
The switch disconnects the DC current from the PV panels in the "OFF" position. The inverter will stop producing power, but DOES NOT disconnect
the AC from the grid. To prevent electrocution hazards, all the connection operations must be carried out with the external AC disconnect switch
downstream of the inverter (grid side) open and locked out.

This device complies with Part 15 of the FCC Rules. Operation is subject to the
conditions: (1) this device may not cause harmful interference, and
following two
(2) this device must accept any interference received, including interference that may
cause undesidered operation.
•
The PV source conductors must be Listed PV wire per NEC 690.35. PV output conductors shall 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.
•
To reduce the risk of fire, connect only to a circuit provided with 15A, 20A, or 25A maximum branch circuit overcurrent protection in accordance with the NEC (ANSI/
NFPA 70). The inverter must be connected only to a dedicated branch circuit provided with the maximum branch OCPD listed in the technical data table, section 13.
•
All models listed in the technical data table, section 13, have an integrated DC disconnect switch rated 600V/25A per contact.
•
Maximum array DC voltage input to each MPPT circuit is 600 Vdc under any condition.
2.
Environmental checks - See technical data table, section 13, to check environmental parameters.
•
Maximum operational ambient air temperature must be considered when choosing location. Installing the inverter where
operating temperatures exceed specifications will result in power derating. It is recommended the inverter be installed
within specified temperature range.
•
Exposure to direct sunlight will increase operational temperature of inverter and may cause output power limiting. It
is recommended to use a sun shade to minimize direct sunlight when ambient air temperature around unit exceeds
104°F/40°C.
•
Due to acoustical noise (about 50dBA at 1 m) from inverter, do not install in rooms where prolonged presence of people
or animals is expected.

Install on a wall or strong structure capable of bearing weight.

The maximum allowable input short circuit current limit of the PV array for each MPPT input channel is 20Adc for 3.6kW, 3.8kW and 4.2kW inverters; 12.5Adc for
the 3.0kW. Array equipment grounding must be installed per the requirements of the NEC and is the responsibility of the installer.
The transformerless design requires that the PV array to be floating with respect to ground per NEC 690.35.
•
The inverter can be configured with two independent maximum power point tracking (MPPT) channels or as a single channel with one MPPT
by paralleling the two channels.
•
Parallel two inputs when the current from PV array exceeds 20 Adc for the PVI-3.6/3.8/4.2 or 12.5 A for the PVI-3.0, or array power exceeds
limit for single channel (section 13).
•
Switch S1, located on the inverter connection board, is used to select parallel (PAR) or independent (IND) input mode
•
The default position of switch S1 is set in the IND mode (DOWN).
•
To access the switchbox wiring and Switch S1, loosen the four captive screws on the inverter cover and wiring box cover using the Torx
wrench provided. Before removing front covers, DC switch must be in the OFF position.
•
When complete, re-install the front covers and tighten the cover screws with at least 1.5Nm (13.2 in-lbs) torque.
•
Use DC knockouts (section 4) to connect raceway from the PV array conduits to the DC array.
Independent mode configuration
•
Connect array to String 1 and String 2 input positions shown below, running
separate wires for POS and NEG for each array.
•
Up to four strings can be connected in the INDEPENDENT mode.
•
To connect four strings, String 3 and String 4 are connected in addition to 1
and 2, running separate wires for POS and NEG for each array.
•
Confirm switch S1 is set in the IND position (DOWN).
