2.1 Intended Use
The CPS Hybrid PV inverter can be used to converter photovoltaic energy to battery and/or to balance the
attached load power. Please note, that charging the batteries takes presidency over all other functions!
It can supply power to appliances when public grid is not available. The unit contains 2 x 12V/9Ah Sealed
Lead Acid batteries in 24VDC configuration that can be expanded through the use of an external battery
array. It also has a built-in USB charger that provides 2ports with 2A totally maximum, able to charge
connected 5VDC USB devices, such as Smart Phones, Tablets, Cameras, etc.

2.2 Safety Precautions
The CPS hybrid series is designed and tested according to international safety requirements; however,
certain safety precautions must be observed when installing and operating this inverter. Read and follow all
instructions, cautions and warnings in this installation manual.
User Manual 2 Hybrid CPSHB300ETR

2.3 Assembly Warnings

Prior to installation, inspect the unit to ensure absence of any
transport or handling damage, which could affect insulation
integrity or safety clearances; failure to do so could result in
safety hazards.
Unauthorized
removal of necessary protections, improper use,
incorrect installation and operation may lead to serious safety,
shock hazards or equipment damage.

In order to minimize the potential of a shock hazard due to
hazardous voltages, cover the entire solar array
with dark
material prior to connecting the array to any equipment.
Grounding the PV modules: Comply with the local requirements for
grounding the PV modules and the PV generator.
CyberPower recommends connecting the generator frame and other
electrically conductive surfaces in a manner which ensures continuous
conduction and ground these in order to have optimal protection of
the system and personnel.

User Manual 3 Hybrid CPSHB300ETR

2.4 Electrical Connection Warnings
2.5 Operation Warnings
Make all electrical connections (e.g. conductor
termination, fuses, PE
connection, etc.) in accordance with prevailing regulations. When
working with the inverter powered on, adhere to all prevailing safety
regulations to minimize risk of accidents.
The unit may only be operated with PV generators (modu
les and
cabling) with protective insulation. Do not connect any source of energy
other than PV modules to the CPS hybrid inverter.

Systems with inverters typically require additional control (e.g.,
switches, disconnects) or protective devices (e.g., fusing circuit breakers)
depending upon the prevailing safety rules.
Please read this manual carefully, the manufacturer or supplier is not
responsible for damage caused by incorrect operation
, installation,
wiring, transport, etc.
When energy flows into the
house grid through the inverter, household
devices or lighting consume that energy. Leftover energy may be fed into the
public grid. If you choose this function and indeed there is left-over power
fed into the public grid, depending on your connection, th
e energy
consumption meter might be spinning backwards!

Ensure all covers and doors are closed and secure during operation.

Although designed to meet all safety requirements, some parts and
surfaces of Inverter are still hot during operation. To reduce the risk of
injury, do not touch the surfaces while Inverter is operating.
Incorrect sizing of the PV plant may result in volta
ges being present
which could destroy the inverter.
Anytime the inverter has been disconnected from the power network,
use extreme caution as some components can retain charge sufficient
to create a shock hazard; to minimize occurrence of such conditions,
comply with all corresponding safety symbols and markings present on
the unit and in this manual.

In special cases, there may still be interference for the specified
application area despite maintaining standardized emission limit values
(e.g. when sensitive equipment is located at the setup location or when
the setup location is near radio or television receivers).In this case, the
operator is obliged to take proper action to rectify the situation.

5.1 Safety Instruction
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires.
Do not install the inverter on easily flammable materials and
where flammable materials are stored.
Carefully remove the unit from its packaging and inspect for external damage. If you find any
imperfections, please contact your local dealer.
The PV input interface can only be connected with PV panel(s), ant the external battery connector can
only accept SLA battery types in 24VDC configuration.
Disconnect whole connections before servicing.
Do not connect this unit to an AC source or generator.
When a photovoltaic panel is exposed to light, it generates a DC voltage. When connected to this
equipment, a photovoltaic panel will charge the DC link capacitors.
Energy stored in this equipment’s DC link capacitors presents a risk of electric shock. Even after the unit
is disconnected from the grid, external battery and photovoltaic panels, high voltages may still exist
inside the inverter. Do not remove the casing until at least 2 minutes after disconnecting all power
sources.
Although designed to meet all safety requirements, some parts and surfaces of inverter are still hot
during operation. To reduce the risk of injury, do not touch the surfaces of inverter during operation.
5.2 Selecting the Installation Location
The points below help you select a suitable installation location, thus avoiding any potential damages to
both device and operators:
1) Obviously the location selected must be suitable for the inverters’ dimensions, with room to
spare.
2) Do not install the inverter on structures constructed of flammable or thermo labile materials.
3) Never install the inverter in environment of little or no air flow, nor dust environment.
4) The inverter must be installed indoors.
5) Do not expose the inverter to direct sunlight, in order to avoid the power and efficiency de-rating
caused by excessive heating.
6) The humidity of the installation location should be 0~95% without condensation.
7) The ambient temperature of the inverter should be -10
℃
~+50
℃
.
8) The installation location must be freely and safely to get at all times.
9) Vertically installation only. Never install in horizontal positions, and avoid forward and sideways
tilting; (observe drawings below)

1) Remove the cover from the PV panel.
2) Check the PV and AC voltage.
3) If there’s DC switch, turn it to ON position.
If the inverter is connected with PV panel and the input voltage is higher than 27Vdc, while the AC
grid is not connected yet, LEDs will display as below. PV power would be transferred to charge the
batteries.

6) Plug in load to inverter standalone output, inverter will feed-in the residual power to Grid to
balance the power consumption of load (If the residual power is more than load, inverter would
reduce the input power to make the net power to Grid as zero).
6.2 Operation Modes
Self-consumption (On-Grid) Mode
In this mode, the inverter convers PV power to charging battery and/or to balance the load power
consumption; Whenever the DC voltage is lower than 25Vdc, the inverter will work in waiting state and
attempt to connect the grid by 5mins for <25Vdc and 30s for <16Vdc. In waiting state the inverter
continuously monitors the internal system. Grid bypasses power to load directly.
Note: The inverter starts up automatically when DC power from the PV panel is sufficient.
Off Grid Mode
In this mode, whenever the PV or Battery has sufficient power, the inverter convers PV and/or battery
power to loads when Grid power is no available.
Fault Mode
The internal intelligent controller can continuously monitor and adjust the system state. If inverter finds
any fault conditions, inverter would shutdown immediately
Bypass Mode
When no PV power during On Grid operation, inverter off internal switch but keep bypass relay on to
continuously supply loads power from Grid directly.
Charger Mode
If user doesn’t want On-Grid, bypass or Off-Grid operation, wants all PV power to charge battery. Either one
of below ways can make inverter stay in charger mode.
-Disconnect Grid O/P and Standalone, power on PV power.
-Press and hold button for 3s during operation (inverter would back to On-Grid operation after PV
power off and on) if Grid is available.
Sleeping Mode
User can off inverter by press and hold the button for 3s during inverter operation. In this mode, inverter
off all LEDs to save energy but keep monitoring the internal system for quickly going back to normal
operation. When PV power comes back, inverter will enter charger mode automatically. When PV power is
gone, inverter will enter shutdown mode.
