I've got a Deye SUN-12K-SG04LP3-EU inverter and an 16S battery with a JK PB2A16S20P BMS. The setup is 2 meters away from my server rack, housing my servers and network equipment, as well as an UPS located at the bottom of the rack. However, now that I've gotten a complete solar setup, I thought I would use that as the UPS instead.
I thought about hooking up a wall outlet into the LOAD port, so my rack is always powered on, even in the event of a power outage. Right now, even with a battery, the "whole house setup" does not support power outage via off-grid.
The inverter is set to only discharge the battery to 10%, but is it possible to "override" this in the event of a power outage, so the minimum discharge is 5% for example? Obviously this should happen automatically through the Deye inverter. In the winter period, the battery is almost always at 10% a few hours after dark.
My way of doing it "the hacky way" would be to lower the minimum discharge to 5%, and then through Home Assistant or Node-RED artificially keep the battery at 10%. If the battery dips below 10%, charge it up to 10% by unticking "time of use" (which would cost me a few dollars per month, as I would need to buy that electricity). In the event of a power outage, the battery would kick in and keep the rack powered using the remaining 5%. Not ideal but it's a workaround. Not sure if it's worth replacing my existing UPS for, though.
