Hi. Both the Turbine and the mppt controller are 48v 10kw units. The average maximum voltage measured by the mppt is about 30v but the current remains 0 amps.

Hi, I have a 10kw, 3 phase, 48V vertical turbine installed with a 48V hybrid mppt charge controller compatible with Lithium Batteries. It is spinning and the mppt controller picks up voltage coming in (20-30v), but does not pick up any current from the turbine. Can anyone please advise what could possibly cause this. Could it be a polarity issue from the turbine?

My question is this:. I have a 150L normal geyser fitted with a microcare controller and 3 x 455watt solar panels. I noticed that the maximum wattage coming in is around 600 watt. I have a 3kw element in there but the water does not heat up sufficient from solar Will the water heat up more efficiently with a lower kw element?
