I do that trick with a smart solar 150/35 - feed it from a lab supply with 30V and the current maxed out and limit the controller to 20A. Works well on cloudy days (normally charge mine with a 330W panel)
Great work. You said you had the MPPT 100/30 connected to your 48V battery. I thought the MPPT 100/30 only capable of 12V or 24V charging? I assume you connected to a subset of your 48V pack then?
I have used the 48V bank as input or charging source, connected to the PV input terminals on the 100/30, So it is charging my 12V battery from my 48V bank.
really really nice box, with $victron$ it's a pleasure. Have some questions. I can't find the #3 video. And, how do you control to not to let the solar controler alone with the PV or supply if the BMS shutdowns? thanks to share your tools!
#3 was binding the cells in a pack: ruclips.net/video/9yRPL07D9Cs/видео.html I have yet to solve the issue of how to avoid having the charge controller cut off from the battery while still connected to PV. I suppose I could use a solid state relay on the connection from the panels to the cc and have it shut off when it senses lack of 12V on the battery output. Are the Victron charge controllers sensitive to this issue? I know the Midnite Solar Classic is but did not see anything in the Victron manual about that so assumed it was not something I needed to worry about,, And I agree the Victron stuff is pricey but for me it is worth every extra penny spent to be able to monitor and control the system remotely so easily.
@@metagrid9453 no idea, never have one. does your bms have a separate charge port? I see a schematic with the PV relay controlled by this port and the regulator directly to the battery. should work, but didn't test it yet, thanks for the answer and the video link
I will do that as soon as Amazon allows me to become an affiliate. Thanks for your patience. For now you can find many of the parts at www.invertersupply.com/ Anything specific you would like please let me know.

Floating above 14v? Over 3.5v per cell?
I have float set at 13.5
Make a list of parts with links.
