Hello from a Solar Log 200 user


Before posting  a plea for help, I thought I would introduce myself.


My PV system was installed 2.5 years ago (the day after I put the order in the government announced the change in tariff and it was a fraught time with my supplier trying to get and install the panels in time. We just made it!).


It's a split 16 panel system (7 at 205 degrees SSW + 9 at 105 degrees ESE) of Sanyo HIT-N240SE10 (hybrid) panels producing 3.6 kWp. Fairly expensive at the time but gave the best performance to maximise the space on the hip roof. Also it's not made in China. There is a little winter shading. I'm based ion Trowbridge, Wiltshire, so failrly sunny


Output in 2012 was 3,331 kWh and 2013 3,385 kWh


Almost from day one I had a Solar Log 200 installed and the output is sent to a cloud system provided by the German manufacturer http://home.solarlog-web.co.uk/881.html   However, the historic data has disappeared at the moment for reasons explained in my next post! The Solar Log is connected to my ADSL modem/router/LAN so I can interrogate it and configure it and also so it can sent data to the cloud every 15 minutes.


All along I have been thinking of a more active management system but work and then running a big community project put paid to that, but times are changing.


Step 1 has been to get a smart meter installed. It's taken almost a year to get it installed for reasons I wont go into. It's an EDMI Mk7C. The S0 output is meant to show on the graphs. Getting that working is where I'm at.


Step 2 is to have a display in the hall/kitchen to show optimal time to run the washing machine etc, though my wife says there is no need as she can hear the inverter “singing” when the PV is generating good power (the inverter is in the utility room). I'm thinking of using a Raspberry Pi with the display screen kit now the price of the screen has come down. I wont get permission to have a big laptop on the hall/kitchen wall


Step 3 is to then control the immersion to soak up unused energy and I've seen the interesting post by Keith which is using a dedicated controller.


Well I think that's enough of an outline.

Hi Alan,


I read something a while ago which might work for you. Try an old smart phone permanently powered. You would need power for the pi anyway. You can use something like pvoutput which has an app.


Might work out cheaper and no programming required!

Hi Kevin


Thanks for a quick reply and suggestion. Do you think an unlocked SIM-less phone would work? I like the APIs that PVOutput has.


I've also been thinking about a Hudl using my Tesco coupons, especially if they do their offer to double their value. I would though have to install wi-fi - currently I've installed Cat 5/6 for speed and security.

I don't see why it would need to be unlocked even. No Wi-Fi in the house, I am impressed


Hudl sounds like a great idea if it doesn't cost much. Even one of the £50 ones would do the trick. Would you write your own android app or use an existing one?  I've been thinking of dabbling myself so could collaborate if you are.

Nice idea but it's quite a low priority at the moment, more a hobby thing. Current challenge is moving off XP. Been building a Linux system for the last 4 weeks and beginning to think it was a bad move due to legacy data issues. Trying to get the courage to eat humble pie and buy Windows 7

Hi Alan,





Whatever you do don't go back to Windows. Linux is a far superior operating system and once you've installed it you won't look back. Take my word for it. Which Linux distribution have you been trying to install?





Regards,





Avalanche
