- 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 ±10% power tolerance are allowed.
- Any power optimizer, which is connected to an operating inverter in a PV string, will be bypassed when it fails.
- When the MERC-1100/1300W-P is disconnected from inverter or when the inverter is off, its output voltage will become 1 V.
- It is for PV module frame/extruded aluminum profile racking system installation.
- Pay attention to the 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. - When the operating temperature of the MERC-1100/1300W-P reaches 70 °C to 85 °C, 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 causing any damage. - Each PV module under the same inverter must be equipped with a MERC-1100/1300W-P.
- 8SUN2000-450W-P2/600W-P and MERC-1100/1300W-P can NOT be used in mixture under the same Smart Energy/PV Controller.
- It is recommended that strings under the same inverter have an equal capacity. If this is not feasible, the capacity difference between strings under the same inverter must not
exceed 2 kW. Otherwise, the energy yield will be reduced.
