All PV Grid tied Inverters, as well as storage and hybrid inverters, are considered as generators. To be connected to the grid they need to have an approved G98/99 certification as listed on the ENA Website. Please check the G98/G99 compliance status of your product on the ENA type test register at the following link:  ENA WEBSITE to ensure that this is suitable for your project.

If you haven't already done so, we strongly recommend you make your application for approval for a grid-connected system to your local DNO as soon as possible. This process can take between 15-45 days to complete, and is required for all grid-tied energy storage systems as well as solar PV systems (with/without storage). Your contracted installer will usually make the application for you.

Once you have gained approval we can work with your chosen MCS accredited installer (or with you if you are suitably qualified to design the system architecture with us) to arrive at a system specification that is safe, certified and meets your needs.

An MCS certificate is proof that your installation has been designed, installed & commissioned to the highest standard using only MCS certified products by an MCS certified installer. Please note that an MCS certificate is not a mandatory or legal requirement for system installation.

MCS certificates enable consumers to access financial incentive schemes and may be required by some mortgage companies before lending on a property. Being part of MCS ensures that customers are protected by a Trading Standards Institute (TSI) Approved Code of Practice.

To receive an MCS certificate Domestic pitched roof mounted installations must use PV Panels and roof mounting systems that are MCS approved.
