Dead-Front Cover
Notes
The dead-front cover must be
removed when making or modifying
connections in the distribution box,
and reinstalled when connections
have been completed.
To remove the dead-front cover, use
the following steps.
Reverse the steps to reinstall the
dead-front cover.
Remove the screws from the dead-
front cover.
Pull off the dead-front cover.
Mounting the Inverter
Notes
The unit cannot be mounted on flammable construction materials.
Allow 20cm (8in) of clearance to the sides and 50cm (20in) to the top and bottom of the unit for
proper air circulation to dissipate heat.
The unit has an IP20 protection rating and a PD2 Pollution Degree rating. The unit is for indoor
applications only and must be mounted in a protected area that is dry, free of excessive dust and
has adequate air flow.
CAUTION. The inverter is heavy (87lb/40kg). Mounting should be handled by two people.
Do not place any additional weight onto the inverter.
Mounting Dimensions
Wall Types
Stud: The inverter will need to be mounted to the wall using Unistrut. The Unistrut must be secured
to two studs in the wall. There should be two rows of Unistrut installed: one for the backplate and
the other for the side brackets.
Solid: Use the backplate and mounting dimensions to mark for screw locations.
Mount the backplate onto the wall.
Install the brackets the inverter.
Hang the
inverter onto
the backplate.
Secure the brackets to the wall. Note: Screw can go into either top or bottom slot of the bracket.

SYSTEM DESIGN
Load Restrictions
Determining which loads the inverter will support is tricky. Having a good understanding of the system owner’s load usage is
key in configuring the load correctly. If the load is not configured correctly, it will constantly trip the inverter and produce an
overload error. The system will display an overload error when:
The continuous power required by the load exceeds the inverter specifications. When the grid is present, the continuous load
cannot exceed 7kW. When grid absent, the continuous load cannot exceed 5.5kW.
To ensure the load does not exceed the inverter’s continuous, analyze the system owner’s list of essential loads. Note which
hours each load will be running and make sure the total power used per hour does not exceed the inverter limits (7kW with
grid, 5.5kW without grid). Below is an example power usage during a 24-hour period.
Note: Loads should be configured in a way that the system owner can easily limit their load to 5.5kW when there are utility outages.
Equipment with large inrush current cause power surges that exceeds the inverter specifications. When the grid is present,
the inverter can accept power surges up to 7.5kW for 30 seconds. When the grid is absent, the inverter can accept power
surges up to 7.5kW, 6.5kW and 5.5kW for 1, 5 and 40 seconds, respectively.
It is important to know the inrush current of major appliances and equipment. Equipment with motors, such as water pumps,
will have a large inrush upon startup. Soft start devices should be installed to limit the power surges of any equipment with
large inrush currents.
Parallel Operation
Up to 3 H5001 can be connected in parallel. Each H5001 has its own charging
capability and can be controlled to work together, so you can incrementally add
power and storage in parallel at the same time. This makes designing and
configuring sites with larger demands easier.
Note: The installation of a parallel versus a single inverter system is different. To install a
parallel system, refer to the H5001 Parallel Installation Guide.

CONNECTIONS
Notes
Order of wire connections should be Ground, N, L1, L2.
Connect AC wires according to the labels on the terminal block or your system type.
Connect PV wires into the inverter before connecting them to the PV panels.
It is recommended to install surge protection between the modules and the inverter.
This will reduce the risk of damage to the inverter due to surge.

WARNINGS
Make sure the circuit breaker is off before making or modifying any connections.
To prevent the risk of electric shock, make sure the ground wire is properly earthed
before operating this unit whether the grid is connected or not.
To reduce the risk of injury, use the recommended wire/cable size.
Only install monocrystalline or polycrystalline PV modules with Class A rating. Do not
use PV modules with potential leakage current. (e.g., non-grounded PV modules can
leak current to the inverter).
Do not exceed the maximum PV input voltage, doing so can damage the inverter.

Do not apply antioxidant substance on battery terminals connections are made.
System Types: Wiring Connection
Installing Conductors into the Terminal Blocks

Battery Charging Requirements
The default charging parameters are shown below. Use this as a reference to make sure the battery selected is compatible with
the inverter. It is recommended that you use a deep cycle battery when the mode of operation is not set as one of the two back-
up modes.

Charging
process
First - charging voltage increases to 56.4V.
Second- charging voltage will maintain at 56.4V until charging
current is down to 2A.
Third- goes to float voltage at 54.4V.
First – SOC voltage increases to bulk voltage.
Second - charging voltage will maintain until SOC is 99%.
Third- stop charging after 1 hour.
Communication Ports
The inverter has communication ports for data logger communication, battery communication, external display connection and
parallel operation. The ports are located inside the distribution box, on the top bulkhead panel.
PORT
FUNCTION
RJ45
For External Display. The inverter can only connect to external displays provided by Darfon.
RJ12 (x2)
For Parallel (Stacking) Function. Only inverters of the same model can be installed in parallel.
RS485 S
For Data Logger. Check Darfon website for compatible data logger models.
Dip
Switches
For Long Distance RS485 Communication. If the distance between the Data Logger and Hybrid inverter is greater than 50m,
then the termination resistor switch on the Hybrid should be switched ON. If the distance between the Data Logger and
Hybrid is less than 50m, then the termination resistor switch on Hybrid should be switched OFF.
RS485 M
For Battery BMS. The inverter can only communicate with lithium batteries listed in the “Battery Charging Requirements”
section. If installing with Lead Acid or other lithium batteries not listed, the inverter will not be able to communicate with the
battery and the battery type should be set as Lead Acid.
