What make and model of batteries do you have installed?

Hi Paul That's the 3rd gen Givenergy inverter? The 5kW version, which is less than £100 more, will give nominal 5kW AC output (from PV), but still only 3.6kW from battery as per the 3.6kW inverter. Both have the same startup voltage of 150V. How are they proposing to form the strings of PV...

Hi creakyride, sorry to hear of your problems with the companies you have had dealings with, I'm afraid the same issues existed before covid and brexit, I feel it's a case of whoever shouts loudest gets the most attention nowadays and the default attitude of 'you don't get my respect until...

Presumably to get the present battery capacity take the TP58 usable capacity and multiply by the present state of charge ? (assuming SoC reaches 100%) If max SoC you see is 95% then use nominal capacity instead of usable ? https://midsummerwholesale.co.uk/buy/solax/solax-triple-lfp-battery

MCS 2012 handbook guideline is 40-50cm from roof edge (NB I'm not an installer, just reading the doc) https://www.bimblesolar.com/docs/MCS%20PV-Book-ELECTRONIC.pdf you might find easy-pv useful in assessing how many panels will fit, it includes an (adjustable) edge gap and you can set up roof...

Now with edits to provide links for victron kit

From comparing victron 250/85, 250/100, 450/100, my conclusion it that the 250/100 will handle the most PV panels [Edit...] in parallel and input power, the 450/100 will handle more panels as a single string but less input PV power than the 250/100 Have I got it right ? Please could someone...

Blimey, you don't do things by halves do you! Did you need another multiplus too, or is all 28kWh connected to the one unit? Another Seplos BMS ? Bear with me, I'm a slow learner, how long would all that take to charge ? Assuming supply is coming in through a 63A fuse, then 230V x 63A is...

oh my ! What a nightmare to come home to and then to live through for ages afterwards. 2yrs! We all grumble about the cost of insurance, but it's times like that which make it worth every penny. Note to self - check the stop **** hasn't seized up again and can be turned off!

We all have to cut our cloth accordingly :) Better to do one part of the job well and do the rest later when circumstances permit than do a half-baked job and rue the effect for the next 10yrs The battery only option might be worth a look, cheap overnight elec all year round on a suitable EV...

Hi folks, I've been trying to track down installers for Victron on-grid kit operating in herts/beds/bucks, I've looked at victron's website (https://www.victronenergy.com/where-to-buy) but it looks like nothing much between London and Nottingham! Anyone aware of one? Thanks

Thanks for info John, not seen these before, intriguing. Looks tempting for summertime, interesting to hear work well in wintertime too. I wondered if there was some temperature below which heating function would not work. The spec for heating is for outdoor temperatures of -15 to +21C, for...

I had a very noisy PC once due to this problem on a graphics card, not quite screaming, but fan going full pelt continuously. Taking the cover off the gfx card and clearing out all the dust resolved it.

Hello Alan, a number of ppl on the forum have had similar questions, and found solutions IIRC, suggest you have a trawl through the threads, and I think you'll find the answer already here. W.r.t adding battery to existing system, suggest trying searching with retrofit as a keyword. Hope this...

You're welcome. 12x395W panels in SSW, 30deg tilt, in S.E. England suggests about 4500kWh generation in easy-pv. The inbuilt usage profile indicates about 3300kWh would be used directly, with the rest exported - in summer months at peak generation you may not be able to consume all the available...

wrt cables the links in this thread may be useful? https://electricianforum.co.uk/threads/advice-for-diy-solar-install.56143/

Cool, I think that's for a built up area, it sounds like you have opportunity to keep it away from buildings and trees, allowing clean airflow. Savonius designs looked interesting as they look more tolerant to changing wind direction. I was hopeful I could use wind but I'm on a housing estate -...

How many kWp (kWp = kiloWatt peak) of panels do you think you can fit on your roof ? 400W-ish panels are in region of 1050-1150 mm wide and 1750-1850mm long, suggest you have a look at a PV supplier and pick one and rough it out. Allow a border around them, I'm told MCS recommend 500mm border...

Congratulations. Now you just need a wind turbine for that big field.... ;)

Perhaps surprisingly I have no problem with people enjoying it, and I do hope some do, we're paying enough for the pleasure after all;) For me the enforced hype about it is part of what makes me not want to watch it - if you have to make a song and dance act about a song and dance act then...
