    Solar PV install on farm

    A farm I have done some work for are having an array installed by a third party but I have been asked by the farmer to do some additional work not included in the PV install.

    Solar PV panes and power cuts

    Hi I can understand that, during a power cut, an inverter connected to a PV array needs to shut down to prevent maintenance workers on the grid but I don't see why the inverter cannot still continue to provide domestic power. Surely all that is needed is an isolating relay which can distinguish...

    Sunny Beam - Using with multiple inverters

    Hi Guys, We've just installed our first extension to a system so we now have 2 SMA inverters with Bluetooth and the original sunny beam. We'd assumed that the display would show both inverters and allow access to each set of data. Upon commissioning of the second system we found that the...

    Solar Edge, Micro Inverters, Leap of Faith?

    We have been looking at a job with considerable shading on what would be the main location of panels. It is a big late Victorian Semi where we can probably get ten panels on one side and a further 6 on the flat roof above. Nearly all the shading comes from a chimney stack located on the outside...

I don't have a copy of BS EN 62446 at present. Does this include any information specific to testing micro...

The project is located in a Caribbean island that uses 230/400V 60Hz. My solar training is all US focused although I am originally a UK...

    Trend BMS linking in the Inverters production info.

    Anyone got any experience of connecting Inverter/generation meter output into the Trend Building Management System? Need to get the CHP linked up with the PV kit system but not sure how they "talk" to each other. Inverters are SMA's

    Pure sine wave inverters

    I wonder if anyone has used any pure sine wave inverters - or even knows of any that are G83 certified? I have a potential customer that is keen on one if such a thing exists.

    Samil Power 4400TL inverters going cheap - dodgy?

    A bit of a weird one. I've had a phone call from a guy selling inverters as he claims his company has gone bust. Selling Samil 4400TL inverters for £200. Sounds very suspect. Does anyone know of anyone that has had any stock stolen? He is ringing me back shortly but I don't have his number.
