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.
CAUTION. Before installing and using this inverter, read all instructions and cautionary markings on the inverter and all appropriate sections
of this guide.
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. 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.
IMPORTANT SAFETY WARNINGS

BASIC HYBRID PV STORAGE SYSTEM OVERVIEW
INTRODUCTION
The H5000 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 H5000 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.
Note: When PV input voltage is lower than 250V, the power of the inverter will de-rate. This hybrid inverter has two PV
input.

Preparation
Before connecting to the utility, please install a separate AC circuit breaker between inverter and AC Grid utility. This
will ensure the inverter can be securely disconnected during maintenance and is fully protected from over current of AC
input.
Notes: 1. The separate circuit breaker is necessary for safety. Use a 240VAC/40A circuit breaker.
2. The overvoltage category of the AC input is III. It should be connected to the power distribution.
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. Turn off the circuit breaker.
Step 3. For each AC wire, strip 8mm of isolation and then insert
the conductor into the ring lug.
Step 4. Connect the AC wires to the inverter according to the
labels indicated on the terminal block and your grid utility
type. Be sure to connect PE protective conductor (Ground)
first.

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.
WARNING. Never touch terminals of the inverter directly. It will cause
lethal electric shock.

Preparation
Before connecting to the PV strings, install a separate DC circuit breaker between the inverter and each PV string. 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.
Notes: 1. Use 600VDC/20A circuit breakers.
2. The overvoltage category of the PV input is II.
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.
Step 2. Turn off the circuit breaker.
Step 3. Strip 10mm of insulation from the PV cables and insert
the conductors into the cable ring terminals.
PV1+, PV1-, PV2+ and PV2-
Step 4. Check correct polarity of connection cable from PV
modules and PV input connectors. Then, connect
positive pole (+) of connection cable to positive pole (+)
of PV input connector. Connect negative pole (-) of
connection cable to negative pole (-) of PV input
connector.
