• Does the Nano feed the element with DC?

No. The modified wave is safe to control with the existing thermostat.

• What is the maximum power I can connect to the Nano?

The important part is to stay below 200Vmp (240Voc) input, and only 3kW element maximum. 150Vmp with a 3kW element is the recommended Maximum. If too much Amps are available, the Wise Geyser Nano Pi2r (micro) will limit itself to avoid damage. Now that’s being Geyser Wise for you.

• Why not use 30-40V?

Because we feed the standard 230V element, we need a bit higher voltage than our competitors where they mostly use dedicated low voltage DC elements, we make use of the standard geyser element.

• Can I connect panels with more than 7.5A output?

Yes. The Wise Geyser Nano Pi2r (micro) measures the input current and will limit itself to not draw too much amps, ultimately making this geyser wise with this technology added to it.

• My panels are capable of 10A, why is the Nano not using all of it?

Firstly, the element only draws what it wants on a certain voltage. See power throughput formula. Secondly, the Wise Geyser Nano pi2r (Micro) limits itself to draw only 7.5A as not to damage its internal components. Now that’s being Geyser Wise for you.
