Description
Our AC ELWA 2 is a 0 - 3.5 kW continuously controlled water heating device for grid-connected photovoltaic systems. The AC ELWA 2 uses excess photovoltaic energy for your water heating and thus optimizes the self-consumption of the existing PV system. At the same time, self-sufficiency is increased - this protects against unforeseeable or rising operating costs. The continuously controlled PV feed-in power is regulated to zero.
The AC ELWA 2 has our proven optional hot water backup: Even if the sun is not shining sufficiently, the hot water can be heated to the desired temperature using energy from the public power grid. The device can be installed in hot water and buffer tanks.
Advantages of the AC ELWA 2:
- More power: 3.5 kW instead of 3.0 kW
- Easy installation: The heating element and the control unit can be installed one after the other.
- Easy operation thanks to display like the AC•THOR
- Multiple communication options: in addition to Ethernet RJ45 also WLAN, RS485, PWM-in, potential-free switching output
- External temperature sensor included
- An external 3 kW heating element can be connected
- Even more compact design than its predecessor
- Fixed wiring no cable with Schuko plug
- Easy conversion of AC ELWA-E to AC ELWA 2
