With the SMART Home Immersion Heater Controller from Solaredge, excess PV energy can be easily stored in the shape of hot water. Because even if this storage medium is not present as the lithium-ion batteries, it still makes a noticeable contribution to self-use of self-generated energy. Even when used in parallel with a battery system. Communication with the inverter is even easier and more stable with the new concept of Solaredge.
