This is the new Conext MPPT 100 amp, 600 volts DC charge controller by Schneider Electric. It's the highest voltage controller available. When dealing with very high power solar arrays, wire size and the distance from the charge controller are critical design elements. The 600 volts DC input limit allows for a higher string voltage and and overall higher system efficiency. This model is perfect when your solar array must be mounted far away from the charge controller. If you simply configure your array for a higher voltage, you can deliver the power to the controller using a smaller wire size. When you consider the cost savings by using a smaller wire size, this controller may end up saving you a substantial amount of money on installation costs. This controller may also be used to charge batteries from high voltage grid tie arrays.
The Conext MPPT 100 A 600 Vdc solar charge controller offers optimum system performance for DC coupled solar and storage installations, with easy, flexible installation of large PV arrays. With up to 6 kW of charging power, and allowance for over-sized arrays, the MPPT 100 is ideal for residential grid tied self-supply and off-grid systems and is scalable for larger installations. The MPPT 100 600 offers faster installations and lower balance of system costs with 2 string installations and is compatible with Conext XW and SW storage inverter solutions. The MPPT Disconnect RS accessory can be added for NEC 2017 compliance with module level rapid shutdown, as well as equipment disconnect functionality.
