    Hi,

    I use a bit of Ubiquiti stuff in work for networking. Was browsing their site for some firmware the other day and noticed that they are now doing an all in one solar solution.
    Just wondering has anyone here had any experience of their products?

    Was chatting to a chap I know that has his own solar install the past 10 years or so and he reckoned that the microinverters would be an issue, that Ireland uses a different standard to either the US or the rest of Europe.

    Had a search and came up with this but it's making my head ache a bit.

    Seems like a bit of decent kit to my uninitiated eye.

    Micro inverters, where you have one inverter per panel converting DC to AC are much hyped in some quarters, but I think they're a bit of a ticking time-bomb. The one part of a photovoltaic system that is most likely to fail during the lifetime of the system is the inverter. Having that on the roof is daft IMHO. Every time a lightning surge knocks out an inverter the 20 year warranty from the manufacturer doesn't cover scaffolding and getting someone up on your roof to fix it.

    They have their place perhaps, especially on an apartment block with partial shading, and where you can easily get access to the roof. Partial shading on one panel may knock the stuffing out of the whole array, but there are other ways of getting around that problem with panel optimisers, which manage each panel individually, but don't have any grid or power electronics wired in. They have all of the advantages of micro inverters and none of the downsides.

    I don't see where the idea comes that this is simpler than using a single inverter. All you have to do with a standard string inverter is click the panel wires together in series (they come fitted with IP67 connectors to do that) take two wires from the set of panels to the inverter and hook up the grid. Any electrician should be well able for this.

    Quentin,

    Apologies for not getting back to you, I have to admit to forgetting about this thread entirely. Cheers for the info, your reply is greatly appreciated!

    The solar project is on the back burner for a bit and will be revisited if I decide to keep the EV at the end of the PCP deal next year.

    Thanks once more,
    R.
