    Maximum distance between collectors and tank?

    Thanks for the info SpecialistEnergy. I would be looking at 30-35 metres run most likely. Possibly less, apparently there is another spot that gets a decent amount of sun as well that's a bit closer. I'm not in the country at the moment so I'll have to investigate and measure when I get back...

    Maximum distance between collectors and tank?

    Thank you Worchester, that's good to know. I didn't realise that they get quite that hot! I will continue researching what would be needed for piping etc. It's good to know that the system is potentially viable, if done correctly.

    Maximum distance between collectors and tank?

    mattg4321, I'd thought about the option of using PV, but the panels are more expensive and far lower efficiency. So it would end up being far more expensive and providing less of the needed hot water, rendering the system un viable. I will have a look at that plumbing forum, thank you...

    Maximum distance between collectors and tank?

    Hi, I'm looking at installing a solar water system for a friend. He runs a B&B so has much higher hot water needs during the summer, and also a very high annual bill for heating and water. So it seems like he's ideally suited for a solar thermal system to at least reduce the costs. We live in...

    Sensor to detect when a light is turned on

    It looks like replacing the DPDT relay with a 2NC 2NO contactor will give better isolation for the circuits and conform to the electrical regulations. Something like this one: CT1 4P 20A 2NC 2NO 220V/230V 50/60HZ Din rail Household ac contactor | eBay -...

    Sensor to detect when a light is turned on

    Again, in case this thread pops up on someone's google search looking for French wiring regulations. This is a document I found written in English that tells you how to wire circuits in houses to conform to the French regulation NF C 15-100 MEGA -...

    Sensor to detect when a light is turned on

    In case this is of any use to anyone, I found a pdf giving the wiring specifications for many different countries with circuit layouts, earthing requirements etc. Also the exact specifications that each country has to follow. The link is here...

    Sensor to detect when a light is turned on

    That's a good point about the "unique" testing... I'll add something to the arduino program to make sure the inverter stays on for 5 minutes after all the lights are turned off, to get over issues like kids flicking lights on and off. It looks like I'll have to get stuck in to the regulations...

    Sensor to detect when a light is turned on

    I was looking at this inverter https://www.amazon.co.uk/Phoenix-Inverter-VE-Direct-250VA-communication/dp/B01CZJ5PY4/ref=pd_sbs_21_1?_encoding=UTF8&psc=1&refRID=15DVA1318QJJZW1TDMH2 There is an earth connection on the case itself. I can connect this to the main earth line for the property, or...

    Sensor to detect when a light is turned on

    This is all assuming I don't encounter anything too problematic when I get stuck in, like shared neutrals between lighting and other circuits, sockets wired into lighting circuits, and so on. At one point while replacing two adjacent sockets I found 4 different colours of wires being used for...

    Sensor to detect when a light is turned on

    Lucien that's a good point about separation of the circuits. They will be separated within the relay and the supply from the inverter will go through an RCD, but I don't want to risk shocking a worker (even if only a little). I wonder if there is some kind of heavy duty contact breaker that can...

    Sensor to detect when a light is turned on

    Huh, some of the replies only appeared after I posted that last message. Spoon is right in that I want to use the battery as much as possible, and only use the mains as a backup. I'm hoping that I can get peak usage to use maybe 80% of the battery, so there is still a little left over. Power...

    Sensor to detect when a light is turned on

    Regarding feeding into the grid, that starts getting far more expensive than I'm planning. I'm aiming for a parts budget of max about €600. From what I've read, simply connecting in can cost €1500 let alone the cost of parts, multiple thousands with a long long time to break even. From the...

    Sensor to detect when a light is turned on

    Is there anything that can be used to keep the AC circuit energised while the relay is switching? It will be likely a max of about 0.5J needed (based on 0.1s switching time), such a small amount of energy but it's not worth going UPS to cover it.

    Sensor to detect when a light is turned on

    I'm also thinking of adding an arduino to monitor energy usage per day that is drawn from mains vs solar, to give an idea of how well the solar capacity is holding up to the demand. This part is partly an excuse to add an arduino since I'm gradually learning how to program them, but only as...
