PV Phase 2, with planning for Phase 3

[AGT]

Hi All,

Looking for some guidance from the PV experts.

Currently have small 1.7kW system installed in 2011, on the existing roof- no room for more on this.

Last year I purchased some second hand panels 9x245W and sunny boy inverter that I hope to install on my garage, once I replace the roof..

While reading the forum, a reminder installs have optimisers, so a quick measurement on the space under the existing 2011 install could fit 3x 250w size panels either side of a dormer and possibly 6x250W on a recent extension roof.

I see Phase 2 garage roof taking place this year, just awaiting joiner and would fit the sunny boy, if once SWMBO is convinced about phase 3 more than likely a year later due to other jobs, I could fit another 3kW.

What kind of inverter/ optimisers would you recommend for 5kW of panels on different orientation and different angles assuming I replace the inverter from phase 2.

Later I would add batteries, but allow for space for them during the install.

I can deal with the electrics, DNO is Scottish Power.

Thanks in advance for taking the time to read this and reply.

A Solar Edge system probably has the best reputation.

Thanks Nowty, I will have a look at their equipment.
