*1 The maximum power of PV module at STC shall NOT exceed the “Rated input DC power” of MERC -1100/1300W-P. PV Modules with up to +5% power tolerance are allowed

*2 Any power optimizer, which is connected to an operating inverter in a PV string, will be bypassed when it fails.

*3 When the MERC -1100/1300W-P is disconnected from inverter or when the inverter is off, its output voltage will be 1 V.

*4 It is for PV module frame/extruded aluminum profile racking system installation.

*5 Pay attention to PV module wire length. To match PV modules with a split junction box and short output wire, the long-input-cable version (input wire: 1.3 m(+/-); output wire 0.1m(+)/2.9m (-) of MERC -1100/1300W-P is available upon request.

*6 When the operating temperature of the MERC -1100/1300W-P reaches 70 ℃ to 85 ℃, it may shut down due to over-temperature protection and report an over-temperature alarm. After the temperature decreases, it can automatically resume working without any damage.

*7 Each PV module under the same inverter must be equipped with a MERC -1100/1300W-P.

*8 SUN2000-450W-P2/600W-P and MERC -1100/1300W-P can NOT be used in mixture under the same Smart Energy/PV controller.

*9 It is recommended that strings under the same inverter have an equal capacity. If it is not feasible, the capacity difference between strings under the same inverter must not exceed 2 kW. Otherwise, the energy yield will be reduced.
