    Solar PV system with not tied into the grid?

    As anyone out there ever heard of 'readers digest syndrome'? Well, three months on from my first posting, I find myself replying to my own original June posting. I still intend to fit a solar PV array to my roof. During the last three months, I have found this forum to be a most useful source of...

    Circulating Pump Motors Power Factors

    Back in the day, I remember power factor correction taking the form of small cabinets fitted with large electrolytics, the size of large baked beans tins, all with the intention of moving that VI lagging power factor somewhere closer to unity. The old pumping systems have gone to variable speed...

    Solar PV system with not tied into the grid?

    My original aim in installing a solar PV array to my bungalow's south facing roof was predicated on capitalizing on the decades spent in industry looking after electrical distribution systems, machine control interfaces, all coupled together a whole myriad of day-to-day safe working practices...

    Solar PV system with not tied into the grid?

    Ok, thanks for the feedback. Can you give me more details about the pass-through hybrid invertor you have used: product name, power capacity, where you got your unit from etc etc. Many thanks

    Solar PV system with not tied into the grid?

    Series and parallel panel connection? As each panel is effectively a power supply in its own right, it follows that there has to be an optimized form of panel connection. So what is the best configuration of panel connection based on a 14 panel array? I know it will all come down to panel type...

    Solar PV system with not tied into the grid?

    Thanks johnb2713. Just to get this right; I can have a solar array - suitably sized for the primary intension of just running my hot water tank immersion heater, but the reality is that with the water up to temperature, the system will also run anything else on my domestic system up to the...

    Solar PV system with not tied into the grid?

    'Grid tie with zero export' sounds good, but that would infer that I can configure my system not to export. Also, I take it that grid tied would still require phase and amplitude alignment - even if I didn't ever export. Can you expand a little further, as your initial suggestion sounds worthy...

    Solar PV system with not tied into the grid?

    Thanks binky I see your point about the winter sun factor limitations, but a system that uses solar thermal as well looks like a good idea until I get to the bit where evacuated tube arrays are so efficient that come summer I have to use a heat dump! The idea of having to use an air blast...

    Solar PV system with not tied into the grid?

    I know that ordinarily a solar PV system would be tied into the grid, and feeding-in to the grid when not used. But I do not want to feed into the grid, and neither do I wish to go completely 'off grid'. I want to use the solar array to run a 3KW immersion heater fitted to a 300Ltr indirect...
