Here are some of the comments that I've received since starting my business in March 2014:

*  *  *

Many thanks for taking the time to talk to me, it has confirmed that the combination of a good idea, a well executed project and a friendly back up is the way forward.
PH, Wilts

I purchased mk2 kit from you earlier this year and I am absolutely chuffed to bits.. Not once have i had to reset and through out this period has kept my heat store into the 70 degrees.
CC, Notts

The PV router arrived safely and soundly yesterday, which makes it just over a week - very good service from the British Mail there.  Excellent job on the packing. Everything was snug and nothing rattled its way loose during the journey.  I'm delighted with the build quality - it's even better than the pictures on your website and everything is very clear and easy to follow.
JW, New Zealand

I want to congratulate you for your kit high quality,  I built the Mk2 easily, it is now wired to my home electrical system since last Sunday and running fine. 
DD, France

Thanks for all your help so far, now going to rig it up with real pv. This has been an interesting journey, the construction side was fairly straightforward and enjoyable, but the world of Arduino was a steep learning curve, like all things its easier when you know how but its the challenge that makes it worth while and keeps the neural network firing!
ML, Gwynedd

Thank you for your assistance during the build, I am very satisfied with the outcome.
KR, New Zealand

I’m a trained electronics engineer but had an RTA leaving me with no use of one arm so precision soldering is an issue.  Robin built two systems for to my own specification and both are in use and run seamlessly charging a 24v battery bank.  I followed Robins project from the early days and the introduction of wireless control is perfect for my application.
LF, Leics

Thanks for all the help! I am embarrassed to say that it is now working 100%. I missed the link on IC4 altogether. I actually woke up in the middle of the night with the thought that maybe I had missed a resistor or something! That was about the time that you typed your last email - so maybe it was telepathy!
CG, South Africa

I have had your PV router for several months and I am very, very happy with it.
PH, Wilts

I’ve now had my system up and running since 18th March 2014. During this time I have diverted 1565KWh to heat my hot water. I have a 3.3KW solar PV system and also have a gas boiler. Savings over the 6.5 months since install, compared to gas prices, has been £52 or 29.4% of cost of the mk2 pv system. Been very pleased with both the system and the ROI.  [6th October 2014]

Your v4a sketch is working like a charm and the wireless data is being received by a JeeLink on my laptop every 5 seconds. The temperature display is just what I hoped for.
NH, Cyprus

Just e-mailing to say thanks for a great kit, me and my 12yr old boy had much fun putting it
together (kept him away from 240v). Instructions were easy to follow, supply/packaging are professional and a credit to you.  Will defiantly recommend to others.
IS, Norfolk


Your construction is very neat and well laid out.  I am very pleased with the product.
The Schneider Electrical Box gives it a professional touch and the display is professionally
finished. Your packing was first class and there was no damage. 
GC, New Zealand


Even in the dark days of winter the system has managed to divert quite a few KWh. By my calculations the payback for the year has been 43%.
TE, Cornwall

NB. This was for a pre-built system with a display and RF.  For a "basic" pre-built system, which would have diverted the same amount of surplus energy, the ROI would have been 52%.


Just a quick email to say thank you very much for your hospitality and sorting the router kit last sunday, especially when not feeling well.  The assembled unit is working perfectly, producing lots of free hot water, diverting a lot more spare power than I even expected.  Great design and thanks for taking the extra time to give me assembly advice.
PW, Cheshire


Thanks very much for your speedy and interactive service Robin, it was a pleasure doing business with you.
TC, Somerset


Another PV Router success and a tribute to the versatility of your design. Many thanks for having produced it and made it available to everyone.
BT, Shropshire

I love the way the LED flashes so you have a quick view of the power state.  Many thanks for your help.  Great service and support.
RB, Coventry


The router arrived yesterday and the installation was straight forward. Yesterday was sunny so the unit started working as soon as it was powered up. Thank you, the build quaility is superb.
MW, Conwy


I just bought the PCB and build it myself. The result and the performance of the Mk2 is astonishing!
RvD, Denmark


There is only one thing to say about your code - Mk2_RFdatalog_4.ino  (and PCB). EXCELLENT!!
AB, Hampshire


I have both a single phase and a 3 phase hydro system.  In addition to a mk2 on the single phase I have been using 3 seperate mk2`s to divert power on the 3phase.  These have now been replaced by the mk2 3 phase version which has the advantage of utilising spare capacity on any underused phase to balance consumption on another phase - will be a significant saving.  Unlike a solar system the hydro generates 24/7 so these mk2 units have been diverting 3 or more Kw each for several thousand hours.
BF, Carmarthenshire

It has been some time since I received your kit. Just a quick note to let you know that today was my first day with it installed and in service. Your kit was a pleasure to put together.
SC, New Zealand


Your unit is still working perfectly – now two wind turbines running with solar panels and it compensates perfectly.
PS, Ireland


Thank you again for a great piece of work and super service. Even though I have built mine I will still be monitoring your site to see what's new.
DT, Gloucestershire


It is running beautiful out of the Box.
KH, Germany

We are sat in the sun room just discussing the hands on approach and excellent  communication skills you have. Its been an absolute pleasure dealing with you.
DB, Teeside


The Mk2 PV router kit that I purchased from you has been up and running for about 3 weeks and has diverted 30KwH so far.
IR, Aberdeen


I have to commend you on your kit and instructions, well packed, quick delivery, every part labelled and very good instructions, very impressed (and it takes a lot to impress me nowadays).
MC, Cheshire


I'm really impressed with how you put it all together, right down to the packing! Absolutely fantastic!
NW, Oxfordshire


My roof is within 10 degrees of North which is lucky. It is a bit too flat for most of the year (15 deg from horizontal) but good enough. I think the biggest asset is our sunny weather and the PVrouter.
SC, New Zealand

Have received the goods I ordered thanks, I would in the future use your shop again and have no problems recommending you to anyone requiring your services.
DH, Tamworth


The bits arrived today and its all now working.  Thank you very much for help with this I really appreciate it.
DG, London


Hi Robin, just a quick note to let you know my pv router arrived.  I'm very impressed with the quality of the kit! Felt better than unboxing a new computer :-)
MJ, NSW Australia

The router has been running faultlessly for 10 weeks now and has become an accepted part of our furniture.  We are really happy to have the divert facility and really pleased with your implementation.  Thank you!
DW, West Sussex

Thanks for your kit and help. The unit is working splendidly.
TD, Dorset
