Hello. I just finished the setup of my EG4 3000EHV-48 inverter with the intent to use this system as consistent clean power for my computer systems while also minimizing my my power bill by always charging the battery to full between 8 a.m. and 4 p.m. when my Time Of Use Grid power is the cheapest. I do not have a solar array on the system at this time. My use case is as follows:
---------------
EQUIPMENT
Inverter: EG4 3000EHV-48
Battery: LifePower 48V v2
Timer Switch: Smart Plug - Provides on/off control of grid power from 8 a.m. to 4 p.m. for TOU power.
USE
Provide 24/7 power to computer servers while minimizing utility bill by only connecting to the grid from 8 a.m. to 4 p.m. to charge batteries when Time of Use (TOU) rates are the cheapest.
DAILY OPERATION
8 a.m. - Automatic Timer Switch turns on input power from the grid to the inverter with the intent to charge the batteries to 100% during this time. Batteries need to charge to 100% each day during this time no matter what their charge state is.
4 p.m. - Automatic Timer Switch turn off input power from the grid to the inverter and system runs entirely on battery from 4 p.m. to 8 a.m. the next day.

PROBLEM
I currently have this system setup with EG4 battery communication and I'm running into a problem where the batteries will not charge from the grid/utility power during the 8 a.m. to 4 p.m. period unless the battery is down to at least 50% (highest setting available in program 43). Is there a setting in the inverter that will charge the batteries to full anytime the unit has input power (Grid Power)? Ideally, the system would charge to full and use grid power from 8 a.m. to 4 p.m. when my timer switch is ON and providing a grid connection when my utility power is at its cheapest. I'd like to be at 100% battery power each day at 4 p.m. when the timer turns off and the system then operates from battery until the next day at 8 a.m.
Thank you for any assistance that can be provided.
