IMPORTANT SAFETY WARNINGS
PLEASE READ ALL INSTRUCTIONS AND CAUTIONARY MARKINGS ON THE UNIT AND THIS MANUAL BEFORE USING THE
INVERTER. AND, STORE THIS USER MANUAL WHERE IT CAN BE ACCESSED EASILY.
This manual is for qualified personnel. The tasks described in this manual may be performed by qualified personnel only.
Safety Symbols
WARNING. This indicates the risk of electric shock. The presence of high voltage levels may constitute a risk of injury or death to users
and/or installers.
CAUTION. This indicates important information where failure to comply may result in safety hazards or cause damage to this product.
CAUTION. This indicates the risk of a hot surface. The surface may reach a temperature high enough to cause serious burn injuries.
General Precautions
CAUTION. Before installing and using this inverter, read all instructions and cautionary markings on the inverter and all appropriate
sections of this guide. Installing this inverter by licensed electricians only.
CAUTION. Normally grounded conductors may be ungrounded and energized when a ground fault is indicated.
CAUTION. This inverter is heavy. It should be lifted by at least two persons for the safety.
WARNING. Authorized service personnel should reduce the risk of electrical shock by disconnecting AC, DC and battery power from the
inverter before attempting any maintenance or cleaning or working on any circuits connected to the inverter. Turning off controls will not
reduce this risk. Internal capacitors can remain charged for 5 minutes after disconnecting all sources of power.
WARNING. Do not disassemble this inverter yourself. It contains no user-serviceable parts. Attempt to service this inverter yourself may
cause a risk of electrical shock or fire and will void the warranty from the manufacturer.
WARNING. To avoid a risk of fire and electric shock, make sure that existing wiring is in good condition and that the wire is not
undersized. Do not operate the Inverter with damaged or substandard wiring.
CAUTION. Under high temperature environment, the cover of this inverter could be hot enough to cause skin burns if accidentally
touched. Ensure that this inverter is away from normal traffic areas.
WARNING. To avoid a risk of the inverter damage, make sure that the working areas no metal particle and keep clean around the
working areas.
WARNING. Use only recommended accessories from installer. Otherwise, not-qualified tools may cause a risk of fire, electric shock, or
injury to persons.
CAUTION. To reduce risk of fire hazard, do not cover or obstruct the cooling fan.
CAUTION. Do not operate the Inverter if it has received a sharp blow, been dropped, or otherwise damaged in any way. If the Inverter is
damaged, call for an RMA (Return Material Authorization).
CAUTION. This inverter is not allowed to operate in parallel. Do not parallel connect more than one unit in AC output connector.
Otherwise, it will damage this inverter.

INTRODUCTION
The H5001 hybrid inverter provides power to the essential
load by utilizing power from PV panels, the utility and
batteries. When the PV panels (two string input) generates
enough power, the inverter supports the essential load,
feeds back to the grid and charges the batteries, all at the
same time. When the energy generated by the PV panels is
not sufficient to support the essential load, the inverter takes
power from the utility.
To accommodate various power situations, the H5001 is
designed to handle continuous power from PV panels,
batteries and the utility. When the MPP input voltage from
the PV panels is within the acceptable range, between 250
and 430VDC, the inverter is able to feed the grid and charge
the batteries. This inverter is only compatible with single
crystalline and polycrystalline PV panels, and any other type of PV panels cannot be used.
Notes: When PV input voltage is lower than 250V, the power of the inverter will de-rate. This hybrid inverter has two PV
input.

MOUNTING THE INVERTER
Before installation, make sure nothing inside the package is damaged. You should have received the following
items in the package: H5001 hybrid inverter, backplate, brackets, screws and this installation manual.
The following considerations must be taken into account before selecting where to install.
•The unit cannot be mounted on flammable construction materials.
•The unit must be mounted to a solid surface.
•The unit should be installed at eye level in order to easily read the LCD display at any time.
•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 ambient temperature must be between 0 and 50°C and relative humidity must be between 5 and 85% to
ensure optimal operation. Do not operate where the temperature and humidity are beyond the specified limits.
•The unit has a Pollution Degree rating of PD2. The unit must be mounted in a protected area that is dry, free of
excessive dust and has adequate air flow.
•The unit was designed with an IP20 protection rating and is for indoor applications only.
CAUTION. This inverter is heavy (87lb/40kg). Be carefully while lifting and mounting the unit. Installation should be
handled by two people. Do not hang or place additional weight onto the inverter.
Installing the Inverter onto the Wall
Step 1. Use the backplate as a
template, and install
anchors as needed.
Note: If installing onto
drywall, Unistrut needs to
be mounted and secured to
two studs in the wall. The
backplate and inverter’s
brackets are secured to the
Unistrut using Unistrut lugs.
Step 2. Mount the backplate onto the wall.
Note: Use at least two screws, one on
the left the other on the right.
Step 3. Install the brackets onto each
side of the inverter.
Step 4. Hang the inverter onto the
backplate.
Step 5. Secure the brackets on
inverters to the wall.
Note: Use at least two screws,
one on each side of the
inverter.

PV MODULE (DC) CONNECTION
There is a DC (PV) circuit breaker in the distribution box. This system can connect to two strings of PV modules with
MPPT control. Configure each PV input as recommended in the table below. Vmp is a PV panel’s max power point
voltage. The PV charging efficiency is maximized when the PV system’s voltage is close to Best Vmp.

WARNING. Because this inverter is non-isolated, only two types of PV modules are acceptable: single crystalline and poly
crystalline with only Class A-rated. To avoid any malfunction, do not connect any PV modules with possibility of leakage
current to the inverter. For example, non-grounded PV modules will cause leakage current to the inverter.
CAUTION. To reduce the risk of damage due to surge, Darfon recommends surge protection between the modules and
the inverter.
CAUTION. To reduce the risk of injury, use the proper cable size for PV module connection.
CAUTION. Exceeding the maximum input voltage can destroy the unit. Check the PV string voltage before wiring the
connection.
Connecting the PV Arrays
Step 1. For each PV input string, make sure the input voltage is between
250VDC and 430VDC, and the maximum current is 13A.
Note: The inverter can still be installed if you are only using
one PV input string.
Step 2. Make sure the circuit breaker is off.
Step 3. Strip 15mm(0.6in) of insulation from each PV cable (PV1+, PV1-, PV2+
and PV2-).
Step 4. Insert the PV cables into the PV quick connect terminals. Make sure
the polarity for each connection is correct; positive to positive and
negative to negative.
WARNING. Never touch the terminals of the inverter directly. It
will cause lethal electric shock.
WARNING. The final connection for DC strings should be done
at the array not at the inverter.

WARNING. 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.
Connecting to the Grid/Utility
Step 1. Check the grid voltage and frequency with an AC voltmeter. It
should be within the operation AC voltage range of the product’s
specifications.
Step 2. Make sure the circuit breaker is off.
Step 3. For each AC wire, strip 15mm(0.6in) of isolation.
Step 4. Connect the AC wires to the inverter according to the labels
indicated on the terminal block or your grid utility type.
Note: The PE protective conductor (Ground) should be the
first to be connected.
