Safety Caution
Product Overview
Working with and installing electrical equipment is dangerous. Potential
risks include hazards, electrocution and electrical fires.
Solar panels generate electricity as soon as being exposed in sunlight.
To avoid a shock hazard, it's better to keep the panel covered with
something during installation and avoid direct contact with the output
terminals.
·Observe correct polarity with all interconnections between the solar-
panel, charge controller, and the battery. Reverse polarity may
causedamage
·Make sure all wire connections are tight and secure, loose connections
may cause sparks and intermittent behavior
·Do not perform installation in the presence of any flammable materials
·Make sure you work in a well-ventilated area

-Setup the battery bank
The inverter in this system requires a 24V battery bank for running.
With 2 pieces of batteries, the connection should be:
Connect 2 batteries in series to form a 24V battery bank. Method: hook
up each battery’s positive terminal to the other’s negative terminal.
The diagram as below:
-Connect solar charge controller with battery
The solar charge controller should be put indoor. After the battery bank
setup accomplished, wire the controller with battery bank. The controller
has 3 parts of ports, middle ports are for connecting with battery.
Wiring method: Use the controller-battery cable for connection, battery
+ port to one battery’s positive terminal, battery - port to the other’s neg-
ative terminal

-Mount the solar panels
Determine a location for the solar panel that is exposed in direct sunlight
and clear of any shading such as trees, roof overhangs, etc. Ideally, the
panels should be positioned to minimize the wiring distance between
the solar panel and the combiner box.
For Northern Hemisphere installations, the solar panels should be
mounted at an angle facing true south (true north for Southern Hemi-
sphere installations). The mounting angle should be equal to the
latitude location of where you are installing the solar panels. For exam-
ple, the latitude of Miami, Florida, USA is 25 degrees. Therefore, solar
panels installed in this area should ideally be facing true south at a tilt
angle of 25 degrees.

5.1.1 Use Z-Brackets on an rv roof: “Flat Mount”
When mounting a panel using Z-Brackets, a well-nut (also known as
“expansion nut”) is often used on a pre-drilled hole. This procedure
safely secures the panel on thin cabin roofs or RV roofs. Using a
well-nut is recommended, as the rubber expansion prevents water leak-
age.( The Z-Bracket set does not include well nuts)
Step1：Attaching the Z-Bracket to a solar panel
Locate the mounting holes on the solar panel.Solar Panels have four
mounting holes on each side.
Step2：Mark and drill holes
With the Z-Brackets attached to the frame, the panel can be laid on a
mounting surface, making it easier to mark the holes for the well-nut.

-10-
Step 3: Attaching the panel to the roof
Figure picture below illustrates the correct way to use the well-nut. The
rubber flange has to be flushed on the roofline. The Z-Bracket,along
with the flat washer and lock washer, hold the well-nut in place when the
screw is fastened.
Gently insert the well nut into the drill hole . Be careful not to push the
well nut flange completely into the holes. Make sure the flange is
flushed on the roofline.Before attaching the panel to the roof, a film of
caulk can be laid between the RV roof and the Z-Bracket. Even though
the well-nut provides a watertight bond, this provides additional sealant.

-11-
-Setup the panels array
The battery bank and inverter require 24V input from the solar panels
array. So 4*panels should be wired into a 24V array.
Wiring method:
1.Connect each 2 panels in series to make 2 strings of 24V
Each ECO-WORTHY Solar Panel has a pair of MC4 solar cable at the
back of panel that consists of male and female connectors. This type of
connector uses a “snap-in” type of safety locking clips to lock the two
mating connectors, making it easy to install.
For series connections, just plug one panel’s male and the other’s
female MC4 connectors together.

-PV output to solar charge controller
After all panels get wired by Y-branch connector, use the 16.4ft 8AWG
solar-controller cable to connect the solar panel array output wire with
the controller.
MC4 terminals to plug the Y-branch connector terminals, and the
copper-head terminals to the controller PV input port, + for positive
cable, - for negative one.
-Place the inverter
The inverter should be put indoor to avoid raindrop or any other weather
issue that may causes electrical fault. Here some notice should be
followed:
2.Use 1 pair of Y-branch connector to wire 2 strings together in parallel.
Diagram as below:

Connect battery with inverter
Use the cable inside the inverter package to wire the battery bank to the
inverter. There is one battery port on the bottom of hybrid inverter.
Wiring method: one battery’s positive terminal to DC input +, the other’s
negative terminal to DC input -.

·Please do not install the inverter in a humid, greasy, flam mable, explo-
sive, dusty or other severe environments.
·During cabinet installation, sufficient space shall be reserved around
the hybrid inverter for heat dissipation.
·The polarity of the battery input end of this product shall not be
reversed, otherwise the device may be damaged easily or there may be
some unpredictable dangers.
It can be mounted on wall with proper screws, there are reserved
mounting holes on the edge of the unit.

Fusing and Setting
-Fusing position
The requirement to protect photovoltaic systems from overcurrent
conditions is defined in Article 690.9(A) of the NEC. Fuses are required
to protect cables and PV modules from line-line, line-ground and
mismatch faults. The sole purpose is to prevent fire and safely open a
faulted circuit if an overcurrent event were to occur. However, there are
some situations where fusing is not required and is defined by the
following:
Two Strings in Parallel (fusing not required)
So no need to fuse the PV array you built, or the connection between it
and controller.
LCD display screen info：battery present voltage
(Note: the inverter only works when 24V battery bank connected)
-Inverter to appliances
Before booting the inverter, the AC OUT ports should be wired with the
home socket or appliances first.
-Turn on the inverter
When all wirings are done, check if the battery type switcher is at Li-ion,
since it’s connected with lithium battery bank. The final step is to boot
the hybrid inverter by pressing the switch on its bottom.

On the other hand, even though the inverter has built-in fuse, it’s better
to add one fuse in between it and the battery bank. For a 24V 1500W
inverter, the current it receives from battery should be about 62A, so a
75A fuse is recommended.
Testing and Troubleshooting
Testing
Test all electrical and electronic components of your system before
commissioning it. Follow the instructions in the guides supplied with the
components and equipment.
·Test modules connected in series before they are connected to the
system.
·To determine Voc and Isc in the following tests, the module(s) must be
exposed to the sun and not connected to a load. Observe personal
safety when making these measurements.
·Check the open-circuit voltage (Voc) of every series module using a
digital multimeter. The measured system Voc should correspond to the
sum of the Vocs of the individual module. You will find the rated voltage
in the technical specifications of the specific module. If the measured
value is significantly lower than the expected value, proceed as
described under “Troubleshooting an low voltage”.
Fuse

Troubleshooting a low voltage
To identify the commonly low voltage and excessively low voltage, the
commonly low voltage mentioned here is the decrease of open-circuit
voltage of the module, which is caused by the temperature rising of
solar cells or lower irradiance. Excessively low voltage is typically
caused by improper connections of the terminals or defective bypass
diodes.
·First, check all wiring connections to see if it is not open-circuit or is not
connected well.
·Check the open-circuit voltage of each module
·Disconnect the wiring at both terminals of the modules.
·If the measured voltage is only half of the rate, this indicates a defective
bypass diode. By replacing or remove the diode, the issue may be
sorted. Removing the bypass diodes should only be done by a compe-
tent PV technician and the module has to be disconnected from the
system.
In the case of fine irradiance, if the voltage across the terminals differs
from the rated value by more than 15%, this indicates a bad electrical
connection.
-16-
·Determine the short-circuit current (Isc) of every series circuit. It can be
measured directly by connecting the digital multimeter to the two termi-
nals of the series circuit or module. Attention, the rated scale of the am-
meter or the rated current of load should be more than 1.25 times of the
rated short-circuit current of the series module. You will find the rated
current data in the technical specifications sheet. The measured value
can vary significantly, depending on weather conditions, the time of day,
and the shading of the module.

FAQ
A1:The hybrid inverter is not working. The screen is not showing
anything.
Q1:For this situation, there are 3 things to check:
(1)Check for loose, broken or corroded connections in the cables
between the inverter and battery bank.
(2)Check the fuses/breakers in the combiner box.
(3)Verify battery voltage is sufficient to power up the inverter
A2:Everything is hooked up correctly. The sun is shining directly onto
the solar panels but no charge is going to the batteries.
Q2:Check the voltage of the battery bank. The battery bank is most
likely fully charged and the solar charge controller inside the hybrid
inverter has disconnected the solar panels from the battery. The solar
charge controller will reconnect the solar panels to the battery bank
when it requires charging.

Maintenance
The following maintenance is recommended to ensure optimum perfor-
mance and longevity of the solar panel:
•Clean the glass surface of the solar panel when necessary. Always use
water and a soft sponge or cloth for cleaning. A mild, non-abrasive
cleaning agent can be used to remove dirt.
•Check the electrical and mechanical connections every six months to
verify that they are clean, secure and undamaged.
•Inspect the solar panels and make sure the surfaces are free from dust,
dirt, and other debris; clean with a wet cloth or glass cleaner if neces-
sary.
•Check to make sure all structural components, mechanical fasteners,
and electrical connections are secure, clean, and corrosion-free.
•Check and replace damaged components if necessary
