I bought this style unit
https://www.oeko-energie.de/shop1/de/insel-wechselrichter-victron-phoenix800.html
Because it can accept significant higher input voltage (68V) than the successor at 62V or something. It works perfectly with my 60V electric scooter battery if it is charged to only 80 percent or so.
Only trouble is it will drain the battery too far down if unsupervised. Is there any way to adjust the input minimum voltage to around 57V so it shuts off as the more modern units can be adjusted to via app?
Warranty has been voided before so no concern there. Cheers
