How to utilize extra PV panels

[FrozenToast]

Howzit Everyone

I have three 100w Pv panels lying around since I upgraded my system. I unfortunately cannot add them to my current system due to voltage differences in the new panels and my inverter only has one MPPT input.

I have been wondering how can I utilize them and the two 12v 100ah gel batteries I have lying around, any one got any creative ideas?

Thanks

300watts is obviously not enough to heat up a geyser but could it help power it in some way? Like a AC/DC element?

Loan or gift them to grateful family or friends? Those batteries need to be kept charged to stay healthy anyway.
