Solar Injection Testing

Many DNSPs require an injection test for installations of more than 30kW AC connected in their network.

Injection tests include several electrical tests concerned with what happens during a Loss-of-Mains (LoM) event, and its potential impact on the network. These include over/undervoltage, over/underfrequency, vector shift, and rate of change of frequency (ROCOF).

Power Quality Analysis

Several DNSPs require a Power Quality Analysis of the energy produced by the site. At Clean Tech Controls we have a number of Power Quality Analysers suitable for recording data to present to DNSPs. We often carry out this test on the same day as the injection test and provide the results in a commissioning report. These power quality analysers are also available for hire and on their return to our workshop we analyse the data to provide a PQA report.

What Our Clients Say

This company is excellent. We go to them first for Grid Protection Units. They offer great value especially when you add their top notch customer service. As usual, we needed something STAT this week and the team didn't leave us hanging, even finishing it up and testing on a Saturday to meet our timetable. Graham Dennis shout out.
Mark Horsfall (Simmark)

BCJ has always provided great service on the many occasions we have worked with them on our solar projects. They are reliable, responsive, and overall an excellent company.

Big fan of these guys - always answer the phone. They helped me out when Endeavour Energy required a neutral voltage displacement protection function on the solar installation
