1. Safety Instructions
1. Risk of Electric Shock:
Alternating Current (AC) and Direct Current (DC) sources
are terminated in this device. To prevent risk of electric
shock during maintenance or installation please ensure
that all AC and DC terminals are disconnected.
2. Handling your PV-Inverter:
The PV-Inverter should only be handled by qualified
service personnel. When the PV-panel is exposed to
sunlight and connected to the device, it generates a DC
voltage charging the DC link capacitors.
After disconnecting the PV-Inverter from the power supply
and PV-panel, electrical charge can still reside in the DC
link capacitors. Qualified personnel should allow at least 60
minutes after disconnecting, before handling the device.
3. Public Utility only:
The PV-Inverter is designed to feed AC power directly to
the public utility power grid. Do not connect the AC-output
of this device to any private AC equipment.
4. Beware of Hot Surfaces:
Although designed to meet international safety standards,
the PV- Inverter can become hot during operation. Do not
touch the heat-sink or peripheral surfaces during or shortly
after operation.

2. Limited Warranty
The 6000 PV-Inverter comes with a 5 year warranty. An optional
extended warranty may be available by special request before delivery.
This warranty covers all defects due to design, manufacturing and
components. This warranty does not cover damages resulting from:
Improper transportation and delivery
Improper installation
Unauthorized modification, testing or repairing
Usage beyond that described in this manual
Application beyond the scope of safety standards such as VDE,

Acts of nature, such as lightening, fire, storm etc.
Repairs and/or replacement of parts or the device are made at the
manufacturers discretion. Defective parts or malfunction discovered
during installation should be presented in a written report for
confirmation before applying for replacement or repair. The damage
report must be issued within 5 working days after receiving the
PV-Inverter. MPP SOLAR is not responsible for damages beyond the
scope of this warranty.

3. Overview
3.1. Introducing the Grid PV System
The Grid PV System is mainly composed of 4 parts: the PV-panels, the
PV-Inverter, the AC-Connection Unit (the connection Interface) and a
connection to the Public Utility.
When a PV-panel is exposed to sunlight and connected to an inverter, it
generates DC power. The PV-Inverter converts DC to AC and feeds in
to the Public Utility via the AC-Connection unit.

3.3. Front Panel LEDs
There are 2 LED’son Grid tied 6000, one is green and the other is
red. Normally, only the green LED will turn on during operation.
Their indicated status are explained as follows:
Power on (green LED): It lights when Inverter
is running. The only
condition it will be dark is no power provided to
inverter. In
this case, Inverter
is in shutdown mode.
Fault (red LED): Once the LED lights, it means inverter is in “fault”
or “failure”condition. To see the conditions, please refer to section

1. Choose a dry place, out of direct sunlight with ambient
temperature between 0 and 40°C.
2. Select a wall or solid, vertical surface which is strong enough to
support the inverter.
3. The PV-Inverter requires adequate cooling space for heat
dispersal. Reserve at least 20 cm above and below the inverter.
Minimum space 20 cm

wire to N (Neutral); and the Yellow-green
wire to G (Ground). Note that all three wires
should be at least 2.0mmØ
All three wires should be firmly connected.
(8) After checking the 3 wires are fixed properly,
push the AC-output connection set back in
to the Connection Panel. Driver 4 screws

(9) Now screw on the Connector
Locker to lock the bushing and
cable together.
5.4. Connecting the PV-Panel
(1) First make sure the maximum open circuit voltage Voc of each PV
string is below 750VDC UNDER ANY CONDITION.
(2) Always connect PV-Panel positive (+) terminal to PV-Inverter DC
positive (+) terminal, and the PV-Panel negative (-) terminal to
PV-Inverter DC negative (-) terminal.
(3) Each set of PV-Inverter DC terminals takes a maximum DC input
of 8.5A . As a result, 3 pairs of PV-Inverter DC terminals can take a
combined input of up to 25.5A.

(4) To fully optimize the PV DC output set-up, use the following
configuration guidelines:
(a) For PV DC output less than 8.5A, use a single pair of
PV-Inverter DC terminals.
(b) For PV DC output between 8.5A and 17A, use two sets of
inverter DC terminals.
(c) For PV DC output between 17A and 25.5A, use 3 sets of
inverter DC terminals.
5.5. Connecting to the connection unit
The AC connection unit is an interface between your PV-Inverter and
the Public Utility. It may consist of an electrical breaker, fuse and
terminals for connection to both PV-Inverter and the Public Utility. This
Connection unit must be designed by qualified technician to comply
with local safety standards.
5.6. Installation checklist
(1) High voltages exist when the PV-Panel is exposed to
the sun. Exposed terminals of the PV-Panel are live,
and can cause electric shock. Avoid making physical
contact with live parts of the device.
