A solar installation we completed last year.
Big Enphase in-roof installation, with slate tiles to make it look extremely neat. Being part of this almost 200 year old cottage renovation was great. Customer now has panel level monitoring via the app, all the Enphase microinverters I have installed within the loft underneath each panel, which avoids to need for scaffolding/ access issues if a inverter were to fail. Added bonus of being able to monitor every single solar panel (as shown in the pictures attached). This system is really safe, ensuring no high voltage DC is present. We have also used ARC boxes on every MC4 on the roof for even further added safety. We have further, added lighting within his loft, smoke detection, and additional panels and microinverters on a detached garage.

This installation did have Skill Builder film the job which is on youtube for anyone interested. The roofing firm did a great job with the felt, battens and tiling around our system!

Sunsynk 8kW inverter and a Fogstar 16kWh battery installed recently. Customer has no solar panels, this has been installed to load shift all of his day time peak electricity usage to an off peak rate. Ie: charges up at midnight until 6am then discharges the battery as and when the house demands in the daytime.
We have more Fogstar batteries in stock!

Haven't posted in a while. Here is a Sigenergy installation we installed which included 12x Aiko 510W panels, birdproofing, replacing a soil stack vent with a flush tile version, 1x Sigenergy 6kW inverter, 2x 5kWh batteries and the gateway. Customer now can run his house in island mode, so when the grid goes down, his house can keep going, until the batteries deplete or the sun goes down of course!
