    Advice on my installed solar system - missing optimisers?

    TLDR - I have a system that is supposed to have optimisers fitted, but I am not sure they have been fitted. The detail: Back in March I had a solar system installed. It was installed on two outbuildings, and as one of the outbuildings has a tree near it which can cause some shading, I was...

    Quote for Solar PV upgrade: Solaredge + optimisers NE of Bristol After consideration of the pros and cons, I have decided to upgrade my current inverter to the Solaredge 3.6kW with x16 power optimisers. Primarily it is because I like the idea of a 20 year warranty on the inverter (19 years...

    Voltage Optimisers is this going to save you ££££ what do you think

    I'v been looking into voltage optimisers are you really going to save money boasts savings on 8-10% reducing incoming voltage basicly a step-down transformer and prehaps reduces heat loss from over voltage lower voltage higher current? I I believe it's to reduce IR from the Kvar KV calc...

    Looking for experienced Solar Edge installer in Lancashire/Cumbria

    My Solar Edge installation was damaged yesterday by a lightning strike close to the house. The inverter is completely dead - no lights, and no display - and my best guess is that there was a power surge from the panels to the inverter. There could be further issues, but to take matters...

    Voltage Optimisers

    Hi I've been asked about intalling VO4 single and 3 phase optimisers but I have also been looking at the Marshall Tufflex voltis and just wondering if anyone has discovered any pros or cons with either. The voltis seems to be a bit better as it reduces it by a percentage rather than a set...

    Optimisers or micro inverter?

    Hi. I'm looking to get a full 4kw system installed and have had 3 quotes. 1 I dismissed as the company didn't check out too well. The other two quotes appear to both be reputable companies with all similar credentials and warranties. The main difference is one is favouring solaredge and the...
