my-PV AC ELWA 2

my-PV AC ELWA 2: a 3.5kW water heater with linear power control for on-grid systems

The integrated solution for hot water from PV excess

Also as hybrid storage system with battery

AC ELWA 2 is a 3 kW linearly controlled water heating device for grid-connected photovoltaic systems. Alack of residual energy can be imported from the public electricity grid.

In combination with my-PV Power Meter, AC ELWA 2 uses only excess energy from your photovoltaic system. It can be installed in hot water boilers and buffer storages. Heating power is linearly controlled and so practically no energy is fed into the grid and self-consumption increases markedly. Grid-connected PV systems achieve an average of only 30% self-consumption. In an typical household (5 kWp PV system), self-consumption with the AC ELWA 2 can easily be increased up to 75%.

Advantages:

✔ Linear control for maximum energy utilization

✔ Compatible with my-PV WiFi Meter or Smart Home / battery storage systems

✔ Flexible control for various inverters, battery systems and Smart-Homes

✔ Multimode with 6 devices for 3 to 18 kW nominal power

✔ Also for commercial building applications

✔ Automatic hot water boost function

✔ Communication via home network

✔ Easy setup of the system
