- My Robot lawn mower does really not use a lot of power,, but in my solar setup it does, so in this video we improve on that.
I have a old 50W peek solar panel that charges a 95AH 12 volt car battery. That is then inverted up to 230V AC the power the power brick from the lawn mower that uses 32 volt - ish.
There is so many loses in this setup, and the inverter is drawing about 1 Ampe from the battery 24/7, except then the lawnmower is charging,, then it is more.
I did not even dear to hope for th

Even just 1$ a month, comes out to the same as Binge-watching like 400+ of me Videos every month.
My PlayHouse is a channel where i will show, what i am working on. I have this house, it is 168 Square Meters / 1808.3ft² and it is full, of half-finished projects.
I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.

Morten - whenever you and your “Little Menace” make a video together it’s awesome sauce!! I especially liked it when you caught it trying to cut its own tail/cable... “Are you going to cut that cable, you little.......?!?!?” 🤣🤣🤣
Hi Robert Schrader
Thank You very much! It's a little bandit!!
Thank you for watching! :-)
Dc systems are just lovely.
Not converting forth and back is great :-)
Hey morten, i recommend to put a battery undervoltage protection between the step-up-converter and the battery. Have the same board for a led flood light that I build a long time ago. When the battery goes empty, the converter pulls more and more current, resulting in a extreme voltage drop on the battery. Tryed this out myself and the battery voltage goes down to 9V and then the mosfet on the board exploded because there was to much current to hold up the output stable ^^
Hi DashcamDriversGermany
Thank You very much! Do you have one you can recommend ? a cheap one :-)
Thank you for watching! :-)
Normally my Solar Charge Controller protect my Batteries. So I only can search on amazon and found this: amzn.to/2Lq63tB
Nice,, but I just put on a new tiny charge controller,, and it has this battery protection,,, a bit low for my taste but it is there.
you need to connect the converter at the outpit of charge controller to utilise that function else a use a 12v relay to input the converter through its normally open contact. if not the battery will die as mention an year ago!
You can charge the lead acid battery with a buck converter too. Set it to 13.8 to 14v. Connected direct to the solar panel. More efficient than a controller usually too.

Fun video! It's nice to see power being used efficiently. It's always annoying when you get DC power convert it AC just to convert it back to DC.

I’m beginning to understand why the previous owner gave away that robot lawnmower 😆 Repairing old stuff just to make it work properly makes for great videos.
Hi Chris Bautista
This is me having fun improving on it,, they just used main mower.
Thank you for watching! :-)
The first thing that Evil Robot Mower did. Try to cut the cord! Doesn't the stupid thing know. That, it would be committing Cable Side??? Good work, Morten, You saved the Day or Mower, once more:) Oh, and I've often wondered. Just, how much Power Consumption - Wattage, you could save. By eliminating an AC to DC Adapter, in a Battery Powered Circuit. Definitely worth it... Don
Hi Don Bishop

The metal backed PCB is for heat dissipation. It is common to use thermal paste to attach them to a heatsink for passive or active cooling.
Thanks for the video!
Hi Kevin Clingerman
Thank You very much! First time I got a PCB like that,,,, It is rated for 250Watt,, I am using 32,5 watt it only just become hand warm,, glad you liked the video :-)
Thank you for watching! :-)
My PlayHouse yeah I figured 32 watts wasn't enough to justify a heatsink. Julian illett on TH-cam does a lot with solar power and DC buck/boost converters, you should check him out if you haven't already!
great video, love your work! :)

My PlayHouse took you long enough to reply! LoL still disappointed we could meet in person when you were in Vancouver last year!
Never take that battery lower then 12.20v or you will damage it. Deep cycle lead acids can only be discharge to 50%(12.20v). so a 100ah really is a 50ah. Another thing, lead acid batteries have a bad charging efficiency at 85% so your losing 15% of the power that makes it to the battery. You 50w PV is acting like a 42.5w PV not including other losses like not using a MPPT(Max Power Point Tracking) charge controller. (Can't tell if your are using a PWM or MPPT controller or not) Would make a world of difference by boosting your PV efficiency between 10% - 30% over using a PWM controller or lack there off. Also using a solar alignment app to set your panel(s) to an optimal angle adding to the overall effectiveness of your PV(s).
Thank you very much!
Converting power does waist quite a bit. I think 32V is a bit high, I would try it at the 28V.
Hi Scott Downey
Thank You very much! someone else suggested that to,, I turned it down to 30,, for now.
Thank you for watching! :-)
@@MyPlayHouse Nice! 😎👍
I think 32V is the open circuit voltage of the PSU. I bet that if check the voltage during charging, you'll find 28V.
Hi Alexandre .S
Thank You very much! but it was charging!
Thank you for watching! :-)
It could be the lithium battery charge controller asking for more power. If it was a factory battery you might see the 28V. I say give the mower the power it wants! More voltage = more better... until the magic smoke leaves...
cool video
Hi Amber & John Homestead Projects
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
Morten, I do not know if your solar battery charger is PWM or MPPT, but I recommend a MPPT that does the complete charging cycle, or at least that every 15 days a full charge is made, because your video posted the voltage is very low and its panel narrows slightly. So an MPPT has a greater efficiency in small panels.

Morten, buy a 48 volt power supply for your primary server! You'll save some more power ;)
Hi Mighty Halo
Thank You very much! Not a bad idea..
Thank you for watching! :-)
I don't see any fuses.
Also a undervoltage protection would be a nice thing to have.
I would recommend an output of what the power supply tells you and don't go any higher than that.
See also the power supply for how many amps it can deliver and hold you to that.
Hi Geert Pirens
Thank You very much! some of this you will see in the next video.
Thank you for watching! :-)
I would get a second 12V battery and charge them in parallel, then run that boost converter at 24V to the 30V you need. It will be more efficient. The bigger the range those converters have to boost the voltage up the lower the efficiently they are.
Hi squarrl
Thank You very much! I am sure you mean "in seriel" or do you have some other smart way to charge two batteries,, parallel,that is sitting in seriel ?? Solar panel gives out some 14,xx volt.
Thank you for watching! :-)
No I do mean you wire the two batteries in parallel to charge off the solar panel. The mower would charge with the batteries in series. You would need some diodes to make this work.
Using a boost convertor is much more efficient. Imagine the loss of power through the inverter then converting AC to DC then stepping it down. Totally Inefficient but you know that, you might want to place the convertor on an CPU heat sink with some compound and it should be cool. So keep your stick on the ice and don't get shorted. *.* *)*
Hi T Komoski
Thank You very much! I just checked,, the lawn mower has been charging for the last hour,, and the back of the PCB is just hand warm. maybe 40C it pulls 2,5A 12,5Volt so 31,25 watt and it is only the losses in the PCB that warms it up. ,, it can handle 250 watt,, that is not going to work long without a heatsink.
Thank you for watching! :-)
Its a cool idea and if i did do this, i would hook it up to a ups or a giant man sized battery and yeah mansized batteries do exist but very expensive.
Hi the united federation of gamers
Thank You very much! That might be overdoing it!
Thank you for watching! :-)
Smashing mod, you cut out unwanted conversions :-D
With boost converters, the more you boost the voltage the more current is needed from the source :-(.
So you could turn the boost voltage down a tiny bit, try 25V, just a thought :-).
Hi zx8401ztv
Thank You very much! Humm Yes,, maybe start by bringing it down to 30 and then 28,and then and then...
Thank you for watching! :-)
According to worldstandards.eu , the single-phase voltage for Denmark is 230v AC, 50 Hz. EMEA [Europe, Middle East, and Africa] countries use the 230v AC, 50 Hz standard. (Full list on www.worldstandards.eu/electricity/plug-voltage-by-country/ )
Hi Mark Arca
Thank You very much! I know what we use,, this is a off the grid setup.
Thank you for watching! :-)
Nice! Will the new charge controller have a load output that will turn off when the battery gets low? Otherwise you would need a boost converter board with low voltage shutdown, the only problem is that those don’t have much hysteresis so it will just sit there and flicker until the battery stays under that voltage all the time, the charge controllers that have load outputs normally have voltage settings to adjust the on and off of the load. Thanks for sharing!! Good idea!
Hi SuperBrainAK
Thank You very much! Yes to low power,, it has that Load output!
Thank you for watching! :-)
Hey Morten, I'm intrigued by your relationship with this piece of crap. Its almost got a personality after a few episodes. You got it as a faulty unit in the beginning, and then did tons of effort to get it going. My question is - if my garden was like yours, and I bought one brand new, and I did the setup with the guide wires, and everything perfectly - would this thing actually maintain my lawn properly? Is it possible?
Hi Johann Swart
Thank You very much! I like messing with the robot,,, this is my kind of fun. It's not supposed to have a li-ion battery, it's not supposed to run of solar,,, I have made those changes to play.
It does do an deasont job cutting the grass.
Thank you for watching! :-)
Image if it went rogue and started cutting the neighbors lawn.
Hi T Komoski
I could rent it out, and it could make it's own money :-)

You should get DC powersupplies for your servers (one maube per server) and run them from solar the same way
Hi Daniel Tekmyster

Hi Great video, Your suggestion would be great for my problem.
Solar panel open-circuit Voltage: 40V
Battery 12 V (AGM
Controller : PWM controller max input voltage 28V
Can I use D3806 to step down from 40V to 25V and connect to
solar charge controller to charge the battery? Will I lose energy in this converter
in step down mode? Or the module will convert in to Amps from Voltage while step
down?
Thank you
Hi Krishna Kumar Velappan
Thank You very much! there is a good chance your charge controller can take in 40v,, check that first.
Thank you for watching! :-)
hello sir you have good knowledge about solar and device .and i am new in this field can you tell me how can i run dc 36 watt cooler from 50watt solar panel directly and this step up converter can be used thanks your subscriber plz reply
Hi Vivek Mishra
Thank You very much! a DC to DC step up or Down converter might help you on that projekt.
Thank you for watching! :-)
Interesting
Hi Matthew Landon

Couldn't you just use a 24v solar setup and charge the robot directly ?
Hi Mark
Solar panal only gives out 14,, something volt,, I would need to boost that then. Or get new panels. but yes that would also be an option.
Thank you for watching! :-)
what is that measurement thingy you are using called ? and any chance morten that you could make a video explaining how one works and is used ? For your stupid noob viewers "Norwegians aka ME" :P . Also love this kind off videos.
