Dual MPPT Disconnect Combiner Boxes
for String Inverters

AMtec Solar’s Dual MPPT Disconnect Combiner Box allows the installer to combine up to 8 strings each from two separate PV circuits; providing overcurrent protection and disconnecting means (from a single disconnect), while feeding any transformerless inverter with dual MPPT inputs. This low cost, small footprint, and easy to maintain solution is ideal for transformerless inverters from SMA, Sunny TriPower, ABB/PowerOne, KACO, etc…

With ultra fast lead times, highest build quality, and competitive pricing, you’ll be glad you worked with AMtec.
