This chapter introduces the inverter and describes its functional model, network application,
appearance, dimensions, and working process etc.
2.1 Functional Models
【Function】
PV-3000S-V/PV-3600S-V/PV-5000S-V/PV-5000S-HV are single-phase grid-tied PV string inverter
(transformer less) that converts the DC power generated by PV strings into AC power and feeds
the power into power grid.
WARNING
The inverter is transformerless. Add an isolation transformer
before grounding the positive/negative terminal of PV modules
(like Thin Film module) for operation.
WARNING
Do not connect PV modules in parallel to several PV inverters
for operation.

2.4 Working Process
【Basic principle Description】
The PV-5000S-V PV inverter with double MPPT input receives inputs from two strings of PV panel
(PV-3000S-V/PV-3600S-V/PV-5000S-HV PV inverter with single MPPT input receives inputs from
only one string of PV panel). Then the inputs are grouped into two independent MPPT routes
inside the inverter to track the maximum power point of the PV panel. The two MPPT power is
then converted into DC Bus, then the DC power is converted to AC power through an inverter
circuit, Finally the AC power is feed to the Power grid. EMI filter is used on both the DC and AC
sides to reduce the electromagnetic interface; Surge protection is supported on AC side.
【Circuit Diagrams】
Figure 2.9 shows the circuit diagram for the PV-3000S-V/PV-3600S-V/PV-5000S-HV PV inverter
with single MPPT input

【Working Modes】
Three working modes of the inverter are shown as follows: standby, operating, and shutdown.
Table 2.1 shows the conditions for the inverter to switch between working modes.
Table 2.1 Working modes description
Modes
Description
Standby
The PV inverter enters the standby mode when
(1) the input voltage of PV Strings can enable auxiliary power
supply to run, but cannot meet the inverter operation
requirements.
(2) the input voltage of PV Strings can meet the inverter to-start
requirements, but cannot meet its minimum power requirements.
Operating
When the PV inverter is grid-tied and generates electricity, it
(1) tracks the maximum power point to maximize the PV String
output.
(2) converts DC power from PV strings into AC power and feeds the
power to the power grid.
The PV inverter will enter to the shutdown mode if detecting a fault
or a shutdown command)
Shutdown
The PV inverter switches from standby or operating mode to
shutdown mode if detecting a fault or a shutdown command.
The inverter switches from shutdown mode to standby mode if
receiving a Startup command or detecting that a fault is rectified.
The following storage instructions apply if the PV inverter will not be deployed immediately:
Do not unpack the inverter (put desiccant in the original box if the PV inverter is
unpacked).
Store the PV inverter at a temperature range of -40oC to +70oC and with the relative
humidity of 0% to 100% (no condensing).
The PV inverter should be store in a clean and dry place and be protected from dust
and water vapor corrosion.
A maximum of eight layers of inverter (PV-3000S-V/PV-3600S-V), six layers of inverter
(PV-5000S-V/PV-5000S-HV) can be stacked.
Do not position inverter at a front tilt, excessive back tilt, or side tilt, or upside down.
Ensure that qualified personnel inspect and test the inverter before use if it has been
stored for a long time.

DANGER
Do not install the inverter on flammable building materials or in
an area that stores flammable or explosive materials.
CAUTION
Do not install the inverter in a place where personnel are likely
to come into contact with its enclosure and heat sinks to avoid
electrical shock / burn.
【Checking the Outer Packing】
When receiving the inverter, check that the packing materials are intact.
After unpacking, check that the deliverables are complete, intact, and consistent with
your order list.
