How to Connect Inverter to Distribution Board?

How To Connect Inverter To Distribution Board? Understanding how to connect an inverter to a distribution board is a valuable skill that can empower you to manage your power system effectively. It can also help you troubleshoot issues that may arise during or after the installation process, such as a faulty inverter charger, overloaded batteries, and frequent circuit breaker tripping.

Preparing the Wires:

The connection between an inverter and the distribution board is the backbone of your alternative power supply system. It ensures that converted AC electricity from the inverter can be distributed to different appliances throughout your home or office. This process, while seemingly straightforward, requires a thorough understanding of electrical systems and a meticulous approach to guarantee safety and efficiency. If you’re unsure about your ability to handle this project safely, consider hiring a professional.

First, disconnect all Live (Line) wires from the circuit breaker of your double-pole switch lighting circuit. Make sure to also remove power at the Electricity Board meter for the safety of your home. You can then begin working on the installation of your inverter.

Remember to minimize the number of connections between the batteries and the inverter. This will reduce radio frequency interference and improve the Inverters filter capacitor life. It will also help limit voltage drop to less than 2% under full load to prevent frequent low input voltage warnings and shutdown. Use copper wire that is rated for the current to be carried to achieve maximum efficiency.

Next, connect the negative terminal of your battery to the negative terminal of the Inverter. Do not connect flooded and gel cells or batteries of different capacities together. These types of batteries can release explosive hydrogen gas during charging, which could damage the Inverter and void its warranty.

Load Separation:

An inverter is an electrical power converter that converts DC (direct current) from batteries into AC (alternating current) power used for running appliances and electronics. When installed correctly, it is able to provide a backup source of electricity for lights and outlets during power outages or in off-grid situations. Connecting an inverter to a distribution board (DB) is a necessary step that allows the inverter to be connected to various circuits and outlets in the home or office.

During the installation process, it is important to take safety precautions and follow proper wiring techniques. In addition, it is a good idea to install manual cut-over switches and fuse boxes to protect against electrical faults and overloading.

When performing load separation, it is important to determine which appliances will run on inverter power and which will not. Once this is done, a separate wire circuit should be created for the appliances that will run on inverter power. During this step, it is also a good idea to strip 1/2 inch of insulation from the ends of the wires that lead from the inverter to the breaker panel.

Next, select the breaker panel that will be used to connect the inverter. Once the breaker has been selected, remove the cover and unscrew the mounting screws that hold the front plate. Then, use a screwdriver to knock out the tab on the back of the panel that is located at the top and center. This will reveal a space for the new circuit to be connected.


Connecting the Inverter to the Load Separated Circuit:

Understanding how to connect an inverter to a distribution board is a critical power management skill. This process allows users to easily power lights and plugs during power outages or in off-grid situations. It also helps ensure that the power system is safe and efficient. However, it is important to remember that this step should always be performed with utmost caution and a keen eye for safety. If you are unsure about any aspect of this process, it is best to consult with a professional electrician.

After preparing the wires and performing load separation, the inverter can be connected to the distribution board. It is essential that the inverter’s DC disconnect switch and class T fuse are properly sized for the inverter. An undersized disconnect switch or fuse is a fire hazard and will lead to fires and/or equipment damage. The inverter’s chassis ground should also be grounded. This will protect the inverter from electrical shorts and faults.

It is also important to consider the capacity of the DB board when connecting the inverter. Be sure that the DB board can accommodate the inverter’s circuit breakers and other components without overcrowding the area. It is also a good idea to install manual cut-over switches and fuse boxes to protect the inverter from overloading. These features can prevent fires and other electrical hazards.

Grounding the Inverter:

It is a good idea to ground the inverter as well as the system to which it will be connected. This will help prevent accidental electrocution should an appliance fail. However, you do not want to connect a ground wire to the Neutral (white in color) or Hot (black in color) wires of an appliance. This could cause a short circuit to the ground. Instead, a ground wire should be attached to the inverter’s enclosure grounding terminal. Then, the enclosure ground wire should be connected to a convenient Earth Ground point such as a metal water pipe or a grounded metal plate that is partially buried in the ground.

Once the wiring is complete, test the system to ensure that everything works as it should. You should also check the manual cut-over switches and fuse boxes to make sure they are functioning properly. If you encounter any problems during or after the installation, consult the inverter’s user manual or seek professional assistance.

Inverters are commonly used in RVs and vans to provide power for appliances and electrical devices during off-grid situations. It is important to divide AC loads into two separate AC subpanels to capture the AC loads that will be powered by the inverter and those that will be powered by the generator battery. In addition, it is important to ground the inverter and the overall system to help prevent dangerous shock hazards.
