I have sold and installed dozens of the DLS line of chargers and the latest models are turning out to be very reliable. I use them in conjunction with EXELTECH inverters in hybrid solar systems as back up power at night and during cloudy days. The only complaint I have with the 90A model is the difficulty in reaching the voltage adjustment potentiometer. To reach it the fans must be removed. I need to reach this pot to be able to balance units when I use several IOTA's in parallel.
