The same way a 2 seat car, can tow a large cargo trailer. Never. It can't be done.

A 125w panel, on a average sunny could possibly harvest 500 watt hours. If you fed that into a 7.5kva 120VDC inverter (whatever that is). No.

A 5,000 watt inverter would consume your 500wh in just a few minutes, leaving your battery totally dead. Then it would take several days for the PV panel to recharge the battery before you could use the inverter again.

Example - I have a 3,000 w PV array, and a 6,000 w inverter, and I can still discharge my battery bank in just a couple hours. You have to carefully manage your loads, and your charging

Just like your other question, Impossible and cannot be done, you are SOL.
