Solar PV Protection Units for over 30kW
When connecting a solar generator to the grid which is over 30kW, the distribution network service provider (DNSP) will normally require you to have some extra protection in place. Our Solar Protection Units reflect the requirements of the DSNPs when connecting to the grid.
Our barebones control and protection boards can offer the following features:
- Mains Disconnect / Anti-Islanding Protection Function
- Power Output Ramping Control Available
- Suitable for up to 8 inverter inputs
- Made to Australian Standards
- Plug and play easy installation
- Technical Support Available
- Powder coated IP65 enclosure
- Approved in all states
- Custom corporate branding
- Zero Export Protection Relay Available
Whilst any or all of the above can be put into our boards, we would like to talk to you directly about your needs. Let us help you find a solution that is right for you.
Here are some of the custom features available for our products.
Some DNSPs may allow you to export as much power as you want to the grid. Here you have to have the minimum standard of relay to protect the power quality being exported.
Some Electrical Supply Authorities limit the amount of power that you can export onto the grid. As well as power quality protection, they require that the solar system has protection so that it doesn't export more power than allowed.
In some locations where there is a large amount of embedded generation, the DNSP may not allow you to export to the grid at all.
We can accommodate the need for power output ramping which is sometimes required by the DNSP.
For ramp control options we use a Programmable Logic Controller. This is the industry standard for reliability and robust operation.
Our boards can be fitted with an optional HMI display. Standard size is 5”, but we are happy to accommodate any custom requirements for your project.
Motorised Circuit Breaker
We make use of MCBs to consolidate isolators and contactors, as a space saving design feature. This gives you more space to install cables, and increases airflow within the board to improve heat dissipation. This is also one of the factors that gives BCJ Controls the most compact solution on the market.
For additional communications such as remote monitoring and reporting, we can install an industrial-grade Ethernet hub.
For long distances, or for the simple convenience, we can incorporate 3G-capable modems with an industrial rating into our boards.
Moisture ingress into panels can cause problems for electrical components, particularly electronics such as protection relays. This can be caused by high humidity or temperature variations. Such conditions can be natural, or caused by industrial processes. Provided the board has good heat dissipation, an internal heater is the best way to keep the board warm and dry. All our boards come fitted with a resistance heating unit with thermostat as standard.
