Either the hybrid or the asynchronous inverter will allow you to connect directly to the grid (alongside an ATS and associated electrical components). As you get set up, choose components that'll allow you to prioritize where your system gets its energy. Solar inverters operate by receiving the DC electricity generated by solar panels and converting it to AC electricity compatible with homes and. . Solar-plus–battery storage systems rely on advanced inverters to operate without any support from the grid in case of outages, if they are designed to do so. Deployed in under an hour, these can deliver anywhere from 20–200 kW of PV and include 100–500 kWh of battery storage. For safety reasons, they turn off when the grid goes down to prevent electricity from back-feeding through power lines that might have repair workers servicing them.
