the power loss is due to electronic inefficiencies, which are totally normal. the most important aspect of such a controller is HOW WELL it tracks the maximum power point, that is, regulate panel voltage for maximum power. That voltage is higher at low temperature and high luminosity, and lower when the panel gets hot and the sun is weaker/cloudy sky
I totally agree with you. As far as I can tell it's doing a good job. But to be honest, there are probably someone out there who knows more about this then me. There is always a bigger fish in the sea 🙂
@@ollelund I have a couple of different boost mppt controllers which I will compare under different light and temperature conditions, some of them don't actually asdjust the panel voltage, so they're not searching for maximum pv power. for those who do adjust the pv voltage remains the question how accurately and quickly they find the MPP voltage
Olle...That reminds my of a famous Finish Ice Hockey player, Olli Jokinen anyways Danish hockey fan living in Tokyo Japan trying to optimize solar from my balcony. I have 900kwh abt in 8x 110w panels in parallel. They are only at 18v and so I have to boost it to charge my 24v system. They NEED to be in parallel because of shading issues . I have looked at different options for this. Experimenting with a straight boost converters atm and this is ugly-
Have you tried to use that mppt booster with a victron mppt to improve the output charging rate? So, solar panels connect to the mppt booster, then the booster connects to Victron solar slot to charge the 48v battery
Sorry for responding so late. Became a father some months ago and that gave me zero time for RUclips. To answer you question. No i have not tried that. I think that would actually make the output worse. The Victron would just use up some % and the charging would be slower.. I think... but I might be wrong. Have you tried something like that?
@@ollelund I don’t know it got deleted I guess. Anyway I was just saying thanks for pointing out the fact that the boost controller requires about 10 watts regardless of the task. Good video 👍
It depends what you want to do. If I for example wajt to charge with 50v and have an input of 500w then the ampere will be 10 (500/50=10). So if you want higher amp you will need to charge at a lower voltage.
I use the 600w charge booster for my 48V 16ah Ebike ... No problems whatsoever... As a matter of interest what is the smallest ( wattage )Solar panel you can use on the 300w booster
I have been trying it with a 60 watt solar panel and that was working just fine! I don't have any smaller panel so I don't really know how it would work.. What type of input did you use for charging the e bike
I bought the "600W" one. It wasn't able to drive more than 13A of current (making around 400W max - The panel outputs about 42V@13-14A~ or around about 550W-580W max at Noon) and was rolling back to 200W (and down to about 7-10A) every few seconds because of this while making annoying audible noises. In addition, the unit failed completely after just 1 Month in service. Another useless crappy product from China. I bought from Aliexpress, from a supposed-to-be reputable store with lots of good feedbacks. And of course, no warranty and no refund. Maybe the Amazon version is with better QC, but I will avoid advertising such products without checking them to their full specs. It can prevent more people (like me) from losing their time and money, so please don't recommend those.

Congratulations !!! Very good !!!
Thank you! It makes me glad to heat tjat!
Nice Video Olle! THank you!
Glad you liked it!

Question. When charging a battery you should use a pure sine wave inverter to protect the battery. What type of current do it make?
Will it cause problems for a 60v 100ah lifepo4 battery? How many amps does the battery reverse voltage protect? How many amps did you show as a fuse?
Have you tried to use that mppt booster with a victron mppt to improve the output charging rate?
So, solar panels connect to the mppt booster, then the booster connects to Victron solar slot to charge the 48v battery

Nice
Yes I love this little thing !
Hi! does this work with my 275 watts solar panel with 49.10 voc?
Yes no problem. But what is the voltage of the battery you will be charging?
planning to use it for my 72v ebike battery
5:30. Juice. What do you hear Yanny?
What?
@@ollelund Did you see my reply? What happened lol
What happened with what??
@@ollelund I don’t know it got deleted I guess. Anyway I was just saying thanks for pointing out the fact that the boost controller requires about 10 watts regardless of the task. Good video 👍
I hope I didn't delete anything! Well thank you! Hope I could help! 🙂
Nice.
Thanks!
Thanks!
Is it possible to set up the Ampere ?
It depends what you want to do. If I for example wajt to charge with 50v and have an input of 500w then the ampere will be 10 (500/50=10). So if you want higher amp you will need to charge at a lower voltage.
How to factory reset 600w controller?
Did you find an answer to this?
What is the brand name of the blue controller?
Sunyima is the name I have found
@@ollelund thanks a lot for your quick reply!
Large capacitor is the way to go
You might be right!

If ur failed it dont mean others failed, most are user fault
Elejoy is better.
I haven't tried that. Why is it better?
