Description

LG RESU 12 with SolarEdge StorEdge three-phase Inverter SE5K + S440 optimisers

SolarEdge inverters do not have an MPP tracker, but instead feature two inputs for the SolarEdge module optimisers. Thanks to fixed-voltage technology, the SolarEdge inverter always operates within the optimal input voltage range, regardless of the number of modules and strings. The power data from each individual PV module optimiser is transmitted to the SolarEdge Inverter via the string cable and can be viewed via the internet on the SolarEdge Monitoring Portal

The new inverters are not equipped with a display. Commissioning the inverter is quick and easy using the SolarEdge app on a smartphone.

With the integrated 48 V battery connection, it ticks all the boxes! BYD LV or LG batteries are compatible with this system.
