1 Notes on this Manual
General Notes
The HPS series is a transformerless solar inverter with indenpendent MPP tracker.
It converts the direct current (DC) from a photovoltaic (PV) array to grid-compliant
alternating current (AC) and feeds it into the utility grid.
1.1 Area of validity
This manual describes mounting, installation, commissioning and maintenance of
the following inverters:
HPS-1500/1500D
HPS-2000/2000D
HPS-3000/3000D
HPS-3680/3680D
HPS-4000/4000D
HPS-5000/5000D
HPS-6000/6000D
HPS-6500/6500D
Note:
The series of HPS-1500D/2000D/3000D/3680D/4000D/5000D /6000D/6500D have
LCD display.
1.2 Target group
This manual is for qualified electricians only, who must perform the tasks exactly as
described.
All persons installing inverters must be trained and experienced in general safety
which must be observed when working on electrical equipments. Installation
personnel should also be familiar with local requirements, rules and regulations.

1.3 Symbols used in this manual
The safety precautions and general information are used in this manual as follows:

2 Safety
2.1 Intended use
1. HPS converts the direct current from PV array into grid-compliant alternating
current.
2. The product is suitable for indoor and outdoor use.
3. The product must only be operated with PV arrays (PV modules and cabling) of
protection class II, in accordance with IEC 61730, application class A.
4. PV modules with a high capacitance to ground must only be used if their coupling
capacitance is less than 1.0μF.
5. All components must remain within their permitted operating ranges at all times.
6. The product is also approved for the Australian market and may be used in
Australia and New Zealand. If DRM support is specified, the inverter may only be
used in conjunction with a Demand Response Enabling Device (DRED). This
ensures that the inverter implements the commands from the grid operator for
active power and reactive power limitation at all times. The inverter and the
Demand Response Enabling Device (DRED) must be connected in the same
network and the inverter communication interface must be activated.

2.2 Safety standards
HPS inverters comply with the EU Low-Voltage Directive 2014/35/EU and the EMC
Directive 2014/30/EU. HPS also complies with the requirement for safety and EMC in
Australia and New Zealand market. They are labeled with the CE mark and RCM
mark.

3.2 Checking for transport damage
Thoroughly inspect the packaging upon delivery. If you detect any damage to the
packaging which indicates the inverter may have been damaged, inform the
responsible shipping company immediately. We will be glad to assist you if required.

4 Mounting
4.1 Ambient conditions
1. Be sure the inverter is installed out of the reach of children.
2. Mount the inverter in areas where it cannot be touched inadvertently.
3. Ensure good access to the inverter for installation and possible service.
4. To make sure that heat can dissipate, observe the following minimum clearance
to walls, other inverters, or objects:
C
5. The
ambient
temperature
should be
below 40°C
to ensure
optimal
operation.
6. Recommend to mount the inverter under the shaded site of the building or
mount an awning above the inverter.
7. Avoid exposing the inverter to direct sunlight, rain and snow to ensure optimal
operation and extend service life.
Direction Min. clearance
Upward 300 mm
Sides 200 mm
Downawrd 500 mm
Front 500 mm

8. The mounting method, location and surface must be suitable for the inverter's
weight and dimensions.
9. If mounted in a residential area, we recommend mounting the inverter on a
solid surface. Plasterboard and similar materials are not recommended due to
audible vibrations when in use.
10. Do not put any objects on the inverter.
11. Do not cover the inverter.

4.2 Selecting the mounting location
1. Mount the inverter vertically or tilted backward by a maximum of 15°.
2. Never mount the inverter tilted forward or sideways.
3. Never mount the inverter horizontally.
4. Mount the inverter at eye level to make it easy to operate and to read the
display.
5. The electrical connection area must point downwards.

4.3 Mounting the inverter with the wall bracket
Mounting procedures:
1. Use the wall bracket as a drilling template and mark the positions of the drill holes.
Drill 2 holes required using a drill with 10 mm bit. The holes must be about 70 mm
deep. Keep the drill vertical to the wall, and hold the drill steady to avoid tilted
holes.
2. After drilling holes in the wall, place two screw anchors into the holes, then attach
the wall mounting bracket to the wall using the self-tapping screws and washers
delivered with the inverter.
3. Holding the inverter and attach it tilted slightly downwards to the wall bracket.
3. Check both sides of the heat sink to ensure that it is securely in place.

4. Push the inverter as far as possible and attach it to both sides of the wall bracket
using the M5 screws.Install an antitheft lock (optional), the lock is prepared by customer.
Dismante the inverter in reverse order.
