All, I have an off-grid customer adding more PV to their 20 yr old array. It would be soooo convenient to find a dual channel controller to keep each array separate, instead of sourcing separate new controllers for each array. . The original controller is not mppt. Arrays are 2kw(old Astropowers on roof) and 5kw( bifacials on ground), respectively. Mixing and matching old and new will not work and is bad practice anyway. Thanks. --
