Water heating from photovoltaics AZ WATER INVERTER (e.g. for NZÚ light) offers efficient direct powering of the boiler from the sun. The optimal economic and technical solution for powering the boiler directly from photovoltaics without the need for large, heavy and expensive technology. According to the set mode, the device directly feeds the boiler from the production of solar panels without unnecessary losses.

For optimal efficiency, the output from the panels is processed via MPPT, which guarantees the optimal operating point and the highest efficiency of electricity production. Since the boiler is essentially a purely ohmic load, the power is processed practically from the first produced watt (> 50W production) of energy from the panels directly to
warm water.

With regard to the universality of use, the output voltage is alternating with the frequency of the network, thereby eliminating the need to use special boilers for DC power supply. The unit is designed for an input voltage of 50 to 400 V DC with regard to the operating voltage of the boiler's heating cartridge.

In practice, the optimal combination of four to five panels with a power of 450-550 W per panel with a boiler at 230 V. The unit is supplied with a temperature sensor, thanks to which it is possible to set the final temperature for heating from FVE or HDO, according to the function mode.

The unit does not need an HDO signal input, it can be switched directly as a consumer (boiler). Of course, the unit is equipped with a fuse on the DC side and a disconnector.
