    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...

    PV Array Testing and Micro inverters

    Struggling to find a great deal of information regarding how to conduct testing and complete the PV Array Test Report. I thought there would have been many people facing the same issues. I don't have a copy of BS EN 62446 at present. Does this include any information specific to testing micro...

    Solar Edge (or other micro inverter) advantage when shading is minimal?

    Just wondering about your thoughts on whether I lost a job to a technically deficient but more expensive design. Basically a customer has a fairly large tree due west of his roof but has been convinced that the shading is severe so he should go for a more expensive quote using micro...

    Canadian and micro inverters

    Hi guys, were hearing stories about an installer from Birmingham buying up all the solar guide leads and going in cheap as chips on Canadians and micros. We've lost a couple to them but by the time we get to the customer they are absolutely convinced that Canadian are the best panels and...

    Micro inverters

    Hi all What are your thoughts on micro inverters, do the initial costs warrant the increase in price over a standard inverter arrangement?

    PV & Micro- Gen

    Hi Guys Been reading various post regarding PV systems etc where like me other forum members have very limited experience with these systems. I will not touch anything to do with that side for obvious reasons, but have been called to look at problems not relating to this eg light / power etc...

    Solar Wdge monitoring

    Would it be worth asking for these on a roof with zero shading? Kind of like the idea of being able to monitor each panel and the fact it's ethernet. This bluetooth for SMA really doesn't impress me.

    Enecsys micro inverters - advice required please

    I am going to be installing these in the near future on very small installations. My question is this; Does the array still require earth bonding as per TL systems? and also, do they suffer the same issues with regards to tripping 30mA RCD's? All help appreciated

    Micro CHP

    Anyone involved in this? Looks like Barker is raising the FITs for it so it may be worth looking at.

    Micro inverters

    Ok, I like the idea of micro inverters, not keen on the extra cost but that will come down and I'm sure the intial glitches will be resolved over the next few months and I love the monitoring system. BUT is it just me - my customers will be on the phone to me every time there's a slight...

    Use of Micro Inverters on one string.

    Hi all, I'm looking at a job where the customer would like to use Micro Inverters on a particular string, due to shading issues. However, we want to add 2 more strings which would be fine with a normal inverter. Is it possible to mix and match like this? I've not used Micro Inverters before, but...

    Micro inverters - Check with DNO

    I have been advised by WPD, my DNO that they are sending a letter advising all customers who notify with micro inverters that they must be disconnected untill a G83 compliance certificate can be provided for the whole install. A generic one for the unit is not acceptable. I have not done a...
