Splitting and Connecting Solar Panels per Bays

A solar power system is comprised of solar panels that generate direct current (DC) electricity. In order to use this electricity in your home or business, it must be converted to alternating current (AC) electricity through an inverter.

When installing solar panels, it is important to consider how many inverters will be required to convert the DC electricity to AC electricity. The number of inverters needed will depend on the size of the solar power system and the electrical load it is designed to support.

To ensure that each inverter is operating at its maximum capacity, it is best to split the solar panel installation into bays, and each bay should be connected to a specific inverter. This means that each inverter is responsible for converting the DC electricity generated by a particular set of solar panels into AC electricity. By splitting the panels per inverter, you ensure that each inverter is operating at its optimal capacity.

Connecting Inverters to Existing Electrical Infrastructure

Once the solar panels are connected per bays to the inverters, the next step is to connect the inverters to the existing electrical infrastructure. This is done through the LV AC switchgear, which is responsible for distributing the AC electricity throughout the building.

Connecting inverters to the LV AC switchgear may require good selection and some modifications to ensure that the inverter output is compatible with the existing electrical infrastructure. The inverter produces AC electricity at a different voltage and frequency than the electrical infrastructure, and it is necessary to adjust the voltage and frequency to ensure compatibility.

Required LV AC Switchgear Modifications

To connect the inverter output to the LV AC switchgear, the first step is to install a dedicated circuit breaker for each inverter. This circuit breaker ensures that the inverter is isolated from the rest of the electrical system in case of a fault or failure.

The next step is to modify the LV AC switchgear to accommodate the number of circuit breakers required.

Finally, it is important to ensure that the LV AC switchgear is rated to handle the additional load that the solar power system will be placing on it. This may involve upgrading the switchgear or adding additional capacity to the system.

Connecting solar panels to the existing electrical infrastructure requires careful planning and consideration. By splitting the solar panel installation into bays per inverter, you can ensure that each inverter is operating at its optimal capacity. By modifying the LV AC switchgear, you can ensure that the inverter output is compatible with the existing electrical infrastructure. If you are considering installing a solar power system, it is important to work with a qualified professional who can guide you through the process and ensure that your system is installed safely and efficiently.
