Please turn off Caps Lock.

To charge the UPS from a solar panel requires a panel VA rating considerably greater than the aggregate VA rating of the proposed loads, multiplied by the sustain time for the UPS, divided by the number of hours of daylight at that latitude, which isn't presented in the original posting.

It seems abstruse wanting to take such a variable and dilute power supply as sunlight and making it into an uninterruptible one when, currently, utility supply companies can do a much better job.

Short answer is No.

Based on your OP and responses so far, you do not have the skills or knowledge to do this safely.

The UPS only uses the Batteries during mains fail and will generally support the load for 10-15 minutes at full load.

The UPSs you have mentioned do not have the facility to handle external charging and you would probably destroy the batteries and\or the UPS.

You would be better served to install a grid interactive solar system for the building and use the solar power elsewhere.

Sapper
