There must be an up and over (or other) route for the power to your office- that's the path to follow.
Transmitters in the house; reminds me of the day when the latest new tech was xrays, and the fit of new shoes was tested by xrays of your feet. It was deemed perfectly safe by the companies selling them to shoe stores. (It was NOT safe.)
Now the craze is WIFI, smartphones, IOT and the marketing hype is to have every appliance in the home and more have transmitters, so you will have a pulsed microwave transmitter near your body and head at all times. Independent research shows clearly this is biologically harmful too. Their voice is lost in the tsunami of new tech marketing.
I'm off grid on my own designed 120VDC power system with inverter used only for well and laundry, so no application for on-gridders. I manually don't use electric cooking on dark days, and my batteries are charged fully every day with very low DOD (depth of discharge), so all I need to know is when is there enough PV power for electric cooking, and when can I run the inverter off PV for water pumping or laundry. I plan on adding automation for well pumping and some electric air compressing to my 500 gallon storage tank, based on PV power available and home DC load. All I need to know about power is sun level, battery bank voltage and net charge; if voltage is at bulk and net charge is dropping fairly low, and it's 10AM in the winter they're almost full and I can cut loose on power consumption up to 2000W. Then battery voltage dropping below Bulk or Float tells me I've exceeded PV power. I don't care about SOC (state of charge) because the answer is always 85% or better in the early AM. (Rarely less then 90%)
Or more simply- on dark or reduced power days I don't do laundry or pump water, or do much electric cooking beyond very low power crock pot or tea immersion heater.
