We've been extremely pleased with the Blue Sky 2512i Charge Controller. We are full time cruisers living aboard our 42' sailboat and rely on solar and wind to keep our house batteries charged. The 2512i charger as made a significant improvement in the output of our small 150 watt solar array.

It was very easy to install and was well worth the cost. I feel that the 2512i is giving us the power that an addition 75 watt would have provided at a third of the price.

Great product!
