Plans for this season's work on the MuPPeT solar test rig. A look at Ralph's implementation of this project in Tacloban City, the Philippines. A quick chat about feedback control loops. And the launch of a new project - a simple and very low cost Arduino PWM solar charge controller.

I love your videos!
I have an idea based on many of your concepts and mailbag reviews. I would love to get your feedback and maybe you could do a video on the idea. Not sure of the best way to send you the information, but I have no doubt you have a way.
Just as a intro, it has to do with multiple boost, modular dc out to cryprocurrency miners. I hope to hear from you.
Cheers,
Dan
Can you suggest mppt solar charger controller for 250watt panel having Voc 13.5v
Sir I am having more quire's and my ideas will you share your mail id
Good day sir, I have a solar panel system in my house and i am using this without a Solar panel controller and i think my battery is charging normally. My question is does it affect may battery or Solar panel without a Controller? please send me your email address and i will show you my installation, please excuse my English sir. hoping for your response sir Jualian
Could you make a video of how to use only and arduino and less hardware if its possible… i need to know or learn how to controll a charge with ardunio for up to 12 v only.
the inductance does not seem enough, you might improve performance by increasing the inductance. that noise means your coil does not have enough internal energy per cycle to carry the current.
Hi, Julian.
I've already got most of the bits to put a scaled-down version of this together, but one question, if you can.
What Toroid core did you use? I'm wading through formula after formula to get this bit right, (seems to be critical) and I won't be letting it run with 100% PWM (I've only 3 x 5 watt panels, so I'm gonna stick 'em all in series. Damn sunny in Finland so sshould give me the estimated 5-8 W/h I need per day)
As to the overvolt on the battery, I plan to add into the loop a test that if Vbatt > 13.8, stop the MPPT mularkey, goto light trickle mode until Vbatt gets to about 12,25, then back to muppet-mode. Maybe call these two modes "Statler" and "Waldorf" in thecode….
im from philippines too,..im proud pinoy,..
Is it possible – and economical – to increase the maximum input voltage from solar panels that it's able to handle to 80 or 150 Volts – to allow for serial connected solar panels and wire that's less expensive and thinner ? And to make the output voltage able to charge 12, 24, 36 and 48 volt battery banks? And put up to 40-80 amps into the battery bank, at a maximum watts of around 3000-4000 ?
i just wanna say i have noticed a very high pitch noise whenever your filming near your solar charger. is this the noise the gentleman in the email said was nearly audible?
Excellent – I'm so glad the series is continuing, as I want to build something like this for PiLab (the remote Pi part, anyway).
I was going to base it on the Microchip app. note AN1521 at first, but kinda 'lost the faith' when I found errors in their circuit (Zeta SEPIC coupling caps wrong polarity (?) etc) but as I have a Sleepy Pi – Arduino-based – and I only wanna play with one set of stuff…
Yeah, I was also thinking about the overvolts on the battery, then started thinking about Adafruit's Sous Vide project, which was my first ever introduction to the PID algorithm. Been in the back of my mind if it has a place here…
(way I was thinking was measure the batt. volts, and tell the charger to just stop for awhile depending on the known history. When time's up, sniff battery, measure current and so something with voltage drop and current drawn over time. Early thoughts…)

can you make a playlist of this project videos and attach it to every video as a link (or at least to the future ones). it's pretty time consuming project and people that didn't follow it from beginning (like me) would want to go back and watch it from start.
I'm down in Devon on the coast
Good news – Ralph just emailed me "electricity is back now (march 11,2014)… but I still have the solar system as backup. just in case."
