Solenso AC boxes and AC couplers

AC BOX and AC couplers

AC BOX enclosures bring together metering, protection devices and the grid connection of microinverters, batteries and loads, delivered wired and NF C 15-100 compliant. SoWave AC couplers add a battery to a microinverter system already in service.

The link between production, storage and the grid


AC BOX and AC couplers: connect safely

Between the microinverters, the battery, household loads and the grid, the AC BOX gathers metering and every protection device required by the NF C 15-100 standard. Delivered wired, it saves rebuilding a distribution board on site.

The S-lite and T-lite versions cover single-phase systems up to 10 kW and three-phase systems up to 18 kW. The SPlus and TPlus versions add an automatic transfer switch, up to 10 kW single-phase and 24 kW three-phase.

To add storage to an SG series microinverter system already in place, SoWave AC couplers connect on the AC side, single-phase or three-phase, and allow off-grid operation during a grid outage.

Solenso Power: a cleanly connected installation, from production to storage.
