This product is superb. Previously, I had a miserable offering from Solaner (Spanish) which was rubbish. I have connected 3 x 24v nominal panels in series giving a nominal output of 75v but in fact the output is between 90v and 130v (beware, the Mx60 cannot take more than 150v!). 4 banks of 3x175 watt panels each are connected in paralel and the maximum wattage I have achieved has been 2130 watts. With the previous charge controller I never got more than 1750 watts. The Mx60 charges a 48v battery bank and it is most efficient if you use power while it is being produced rather than try and store the power and use it later so any sunny day put on the dishwasher, clothes washer, swimming pool pump / chlorinater and any other high electric use machine in the morning and let the afternoon sun charge the batteries.

Three items of interest. Firstly the default settings are correct for Exide batteries but PLEASE order the optional temperature gauge as the absorbtion and float voltage levels change hugely with temperature. Secondly, you don't need to equalise Exide batteries providing they reach the float level every so often as the absorbtion voltage and the equalisation voltage are the same. Thirdly, Two sets of friends with 24v systems heard me raving about the Mx60 and bought one - the maximum output is 60A (actually 70 if you alter the default settings) and therefore a 1680W array is the maximum the Mx60 will handle efficiently with a 24v system. A 48v system will easily handle a 3kw array.
