In March 2017 Revolution Energy Services completed a 16.2kWpkWp installation at LFB Hainault for Imtech Inviron as part of a secured RE:FIT Framework agreement. This was the first of the Phase 2 sites for 2017.

This scheme will generate an estimated 14,515 kWh of energy per annum of which all will be consumed on site.

Solaredge inverters and optimisers were used to make the most of the tight roof space and maximise yields. Their products allow for module level monitoring and in this case minimised any shading losses from the tight roof space. In addition, their products negate the losses associated from module mismatch. This can come from manufacturing tolerance, soiling (dust, snow, leaves), temperature differences and partial shading. Over time PV modules also degrade at different rates adding to energy losses over the years. These are all eliminated with Solaregde.

Their superior safety features, with SafeDC, meant they were the perfect solution for the Fire Stations. Unlike conventional string inverters with loss of mains power the system drops to a safe DC voltage of 1V. This meets the highest German and European Safety Standards (VDE 2100, IEC 60947). The product is approved for use on LFB sites for this reason.

Solaredge inverters also comply with the UL1699B arc detection standard designed to mitigate the effects of some arc faults that may pose risk of fire.

The PV systems are connected to an AMR metering solution allowing for remote and centralised monitoring and collection of FIT payments.
