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
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-
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
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.
@@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 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.
