You can definitely find a DC to DC PSU, SA sell one that works great but I'm quite sure if you hunt around you'll find one at a decent price

Ts&Cs reference South African things like the CPA, but the lack of actual street address and landline contact details makes me very wary
As always, if you can't visit them physically and collect, I would stay away

Buy this: https://solar-assistant.io/shop/products/device_opi3lts
Also buy this cable (NOT the micro USB one):  https://solar-assistant.io/shop/products/voltronic_rs232
Setup is easy. Connect PSU cables to your battery terminals. Connect Inverter Cable. Let Pi boot up, go through setup steps outlined here: https://solar-assistant.io/help/getting-started/prepare-device
 
Note: the Pi tends to play nice with the older 2.4Ghz WiFi, not 5Ghz WiFi. If you have signal problems you will experience frequent disconnects

You can literally zip tie the fans together and lay them directly on the heatsink on top to pull the hot air up.

Re : battery charging close to full SOC, that's normal and dictated by the BMS. I think you can do 25 amp charging without any issues tbh

If I remember correctly from setting up Watchpower, first you connect to the inverter with the app, set the correct WiFi credentials so the inverter can connect to the internet, then it will work. It's incredibly buggy and I remember it taking multiple tries and two different phones to get it to work

Used them twice

No. Just look at the lack of aftersales support for them. They're cheap for a reason

Do you know what the load is when this happens?

Without panels it’s not even worth cycling the battery at night because it’s gonna cost you to grid charge and you lose due to conversion inefficiency. I would switch over to grid completely and boot up the inverter maybe once a week to charge, then shut down 

If you're using voltage settings to manage your battery I can safely assume you do not have BMS communication between battery and inverter. In that case, your inverter is "guessing" the State of Charge based on voltage alone, which doesn't really work for lithium batteries.
