I have finished my crate build: Originally a Crate Build: 600 wh, 24 Volt, 300 Watt Inverter, and put a second battery pack to make 1200 wh Goal was to continuously supply 250 watts of power which could get recharged simultaneously by 600 watts of panels. I will call that a success with a test where I ran it for six hours at 220 watts.
Picture of the old 600 wh battery pack
The upgraded Battery pack now 1200 WH
Parts Include A Victron Phoenix 24/375 Converter, A Victron 75/15 SCC, A small Daly BMS 30 amp discharge and 15 amp Charge, Aili Shunt, 8 S 25 ah 24 volt battery pack with TopBand Cells, a 45 amp ANL fuse, and some other things.
Bulk Voltage is 27.5
Float Voltage is 26.7
24 Hour no load voltage the Batteries settle to is 26.7 volts.
In full transparency, I'm going to post my parts list, and links. Please note with this list, there are some tooling up costs included, but there is about a like amount of cost I was able to save by using on part items.
And One Final pic of it in use:
A pic of the on off switch I also have a single USB Charge Socket pair USB-C and USB QC3.0, NS added add two more dual port USB QC 3.0, and a pic of the cut off switch:
