my-PV AC ELWA 2

Maximises solar power for hot water and self-consumption

AC ELWA 2 is a 0 - 3.5 kW infinitely regulated water heating unit for grid-connected photovoltaic systems and is the successor to the AC ELWA-E. It optimises the self-consumption of the existing PV system by using the surplus photovoltaic energy for your hot water preparation. Autarky is also increased and incalculable or rising operating costs can be avoided. The PV feed-in power is regulated to zero by the infinitely variable control.

Furthermore, the AC ELWA 2 has an optional hot water safety function: if there is insufficient solar power, the hot water can be brought to the desired temperature using energy from the public power grid. The unit can be installed in hot water and buffer tanks.

Advantages compared to AC ELWA-E

More power: 3.5 kW instead of 3.0 kW
External temperature sensor included
Simplest installation: the heating rod and the control unit can be installed one after the other
Simple operation thanks to display as with the AC-THOR
Multiple communication options: in addition to Ethernet RJ45 also WLAN, RS485, PWM-in, potential-free switching output
External 3 kW heating element can be connected
More compact design
Fixed wiring, no cable with earthed plug
Simple conversion of AC ELWA-E to AC ELWA 2

AC ELWA 2 in combination with my-PV Wifi Meter

In combination with the my-PV WiFi Meter, the AC ELWA 2 uses only surplus energy from your photovoltaic system. The heating power of the heating rod is regulated continuously so that as little energy as possible is fed into the grid and your self-consumption reaches a maximum. The connection to the router is made via a patch cable or wirelessly via WLAN.

AC ELWA 2 in combination with battery storage system

The AC ELWA 2 is compatible with many commercially available battery storage systems. It takes into account the optimal use and prioritisation of photovoltaic energy.

The battery storage is always charged first. As soon as the battery is full, the AC ELWA 2 takes over the storage of excess photovoltaic energy in the form of hot water. Water is the cheapest form of storage and can be perfectly complemented with chemical storage batteries. This way, the generated electricity stays with you and is not fed into the grid.

AC ELWA-E in combination with Smart Home

Thanks to the system-open control, the AC ELWA 2 also communicates with commercially available Smart Home and energy management systems. The control is carried out by the Smart Home system. In this way, even complex control systems with priority setting of the consumers can be realised.

In residential buildings, systems with multiple devices work together on this basis. Remote monitoring and energy cost billing are possible at the flat level.
