Hello everyone, Recent house purchased and plan for a garden office with PV solar installation. After much frustrating searching for information on solar installation found this forum where people seem to be happy to get into the technical details (unlike websites of companies offering solar installation that I’ve seen). Been a long term renter so my DIY skills low level but IT background so (like to think) have technical aptitude. Looking for advice / voice of experience on a: * 3m x 5m (internal dimensions) garden room. 194 degrees longitudinal axis * 4.2m x 6m flat room dimensions (TBC) * approx 20m from main house at end of back garden * mainly 2 person office Considering installing: 10x 375W AE Power PV panels in E-W facing configuration with ~10 deg pitch 10x S440 optimisers SolarEdge SH3000 inverter Garden Room would also have AC unit Daikin split unit (model TBC) Questions: 1. Can the solar PV inverter be connected to a secondary consumer unit in the garden room or does there need to be a run for generated AC going to the main Consumer unit in the house and a feed from there to the garden room sockets and lights? 2. Maybe depends on answer above but 10mm or 16mm SWA buried spade and a half depth? 3. Looking at CAT6 and / or multimode fibre (intended home switch will have SFP so wondering whether this is a future proofing method into the same trench). 4. Options for digging trench other than by hand - digger hire from Jewson? (Have 1000mm access down side of house) 5. Views on electrical installation for garden room. Which bits need an electrician and or MCS certificate it it worth it, and which bits to do self. There is potential for further PV system on potential house extension (if built) but currently main house roof aspect not ideal for solar (gable end facing south with other main surface north facing) Thoughts welcome.

Hi, I'm just getting a few quotes back on the installation of an in-roof system of 3.84 - 4.2kWp array of 12 PV panels, facing SE with no tree shading whatsoever but potentially a small chimney flue. I am tempted by the SolarEdge addon but not by the price to be honest so my question is if SolarEdge is worth the investment addon or not? Or is there an alternative optimiser that is almost as good? All I hear is SolarEdge are the best but there must other options perhaps that would not cost as much but do the same thing.
