Installation Guide

-Place the hybrid inverter
The hybrid inverter should be put indoor to avoid raindrop or any other weather issue that may causes electrical fault. Here some notice should be followed:

• Please do not install the hybrid inverter in a humid, greasy, flammable, explosive, 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 is required to confirm that the hybrid inverter is the only power supply for the load. It is forbidden to use the machine in parallel with other input  AC power to avoid damage.
  It can be mounted on wall with proper screws, there are reserved mounting holes on the edge of the unit.

-Setup the battery bank
The hybrid inverter in this system requires a 48V battery bank for running.
With 2 pieces of batteries, the connection should be:
Connect the 2 48V 50Ah batteries in parallel, one’s positive terminal to the other’s positive terminal, and negative to negative one.

The diagram as below:![ECO-WORTHY 2400W Off Grid Complete Solar Panel Kit

• diagram](https://manuals.plus/wp-content/uploads/2024/03/ECO-WORTHY-2400W- Off-Grid-Complete-Solar-Panel-Kit-diagram.jpg) Connect battery with hybrid inverter
  Use the cable inside the inverter package to wire the battery bank to the hybrid inverter. There is one battery port on the bottom of hybrid inverter.
  Wiring method: one battery’s positive terminal to the BAT+ port of the hybrid inverter, and the other’s negative terminal to the BAT- port. -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 hybrid inverter For Northern Hemisphere installations, the solar panels should be mounted at an angle facing true south (true north for Southern Hemisphere installations).
  The mounting angle should be equal to the latitude location of where you are installing the solar panels. For example, 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.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: Attach the Z-brackets to the panels
  Attach the Z-Bracket to the solar panel by the pre-drilled mounting holes on the back of the solar panel. Solar Panels have two 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. Step3: Install the panel on the roof
  The 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, holds the well-nut in place when the screw is fastened .Gently insert the well-nut into the drilled 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 roof and the Z-Bracket. Even though the well-nut provides a watertight bond, this provides additional sealant. -Setup the panels array
  The hybrid inverter requires at least 120V DC input from the solar panels array. So the 12 panels should be wired into a series array.
  Wiring method:
  Connect each panel in series to make a total 216V string (each panel has 18V working voltage)
  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 hybrid inverter
  After all the solar array cables get arranged, connect the outlet to the hybrid inverter.
  Use the solar-controller cable for the connection. One side to plug the solar array outlet MC4 head, and the copper terminals to the inverter PV input port .-Inverter to mains(Optional)
  The hybrid inverter has UPS function, if you need to activate it, just connect the unit to the grid.
  There is one AC IN port on the unit’s bottom, there’s 3 separating ports for grounding, positive, and negative connection. Use one proper cable (at least 8AWG) to connect the positive and negative ports with the grid busbar, just plug the copper terminals into the ports, and tie the screws with a screwdriver. -Inverter to appliances
  Before booting the inverter, the AC OUT ports should be wired with the home socket or appliances first.
  Same as the AC IN wiring, you need to prepare one pair of appropriate cable for the ports connection, and just wire the ports with the socket.

-Turn on the inverter
When all wirings are done, the final step is to boot the hybrid inverter by pressing the switch on its bottom.
(Note: the inverter only works when 48V battery bank connected)
There are various icons on the screen, check if the PV, mains, battery, load icons appear. If one icon does not light up, it means this connection to the inverter is not available, so you can have a check on specific item.
It’s able to change the settings when the display lights on. For more settings detail, you could watch the guide video on Youtube:

Fusing and Setting

-Fusing position
Even though the hybrid inverter has built-in fuse, it’s better to add one fuse in between it and the battery bank. For a 48V 5000W inverter, the current it can take from the battery bank should be about 105A, so a 120A fuse is recommended. -Grounding
The hybrid inverter has a grounding screw on the unit bottom for grounding.
A grounding rod is required for actually wire the unit with the ground, it could be easily found in local store or Amazon. The installation steps:

1. Press down the grounding rod into the ground for more than 7.6 inch (50cm) depth
2. Wire one copper cable from the grounding screw to the rod (wire gauge should be 1.5 time as the AC output wire)

Testing axnd 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” .
• 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 mea- sured value can vary significantly, depending on weather conditions, the time of day, and the shading of the module.

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.

FAQ

Q1:For this situation, there are 3 things to check:

A1:The hybrid inverter is not working. The screen is not showing anything. (1)Check for loose, broken or corroded connections in the cables between the inverter and battery bank. (2)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
