Victron systems work well for grid-tied applications, using their ESS operation mode. An energy storage system (ESS) is used to store excess solar power in a battery for later usage on site, backup a property in the event of a power cut, and time-shift usage outside peak grid hours.
For the Victron ESS with solar PV, you need:
Victron ESS systems can be configured for full or partial backup depending on requirements.

In the event of a power cut, the Victron MultiPlus can continue to power loads on its output. The changeover happens so fast (less than 20ms) that even sensitive electronic loads will continue to function without interruption. This is a key benefit of Victron systems compared with other systems (such as Tesla Powerwall) which can take a few seconds to changeover.
Our go-to batteries for Victron ESS systems are those manufactured by BYD.
