Hi, I have a Fox ESS S2500 is it compatible with battery storage or would I need to upgrade the inverter. Thanks
That's a solar only inverter, you have 2 options.
The easiest would be to upgrade to a hybrid (H series) and replace the S series altogether - the hybrid will take your PV string feeds and connect to a battery blending both to power your home, charge your batteries, export to grid etc... as desired.
The second option is to leave the S series and install an AC which is basically a battery inverter (an H series without solar inputs) - but given the price is almost the same it would be much tidier to replace with a hybrid H series.
