MN5048DIY User Manual BAT +: Battery positive electrode BAT - : Battery negative electrode Warnings: ① Mains input, AC output and PV array are all high voltage. So, before wiring, be sure to disconnect the appropriate circuit breaker. ② Be very careful during DC wiring; do not close the circuit breaker during wiring, and ensure that the “+” and “-” pole leads of each component are connected properly; a circuit breaker must be installed at the battery input terminals. Refer to Section 2.2 on pg.
MN5048DIY User Manual Step 5: Install the terminals cover. Step 6: Turn on the MNS Hybrid Inverter First, close the circuit breaker at the battery terminal, and then turn the rocker switch on the left side of the machine to the "ON" position. The "AC/INV" indicator flashing indicates that the inverter is working normally. Close the circuit breakers of the PV array and the AC Mains. Finally, turn on AC loads one by one to avoid overcurrent caused by a large momentary load from turning on loads all at once.
MN5048DIY User Manual 3. Operating modes 3.1 Charging mode 1) PV priority: PV module will charge the battery preferentially, and the battery is charged by the Mains only when the PV system fails. During the day, solar energy is fully used to charge, while at night, it renverts to the Mains. This can maintain battery level, and is ideal for areas where the grid is relatively stable and electricity price is relatively high. 2) Mains priority: The Mains supply is preferentially used to charge the battery.
MN5048DIY User Manual 3.2 Output mode ➣ PV priority mode: Loads are powered by the PV module and battery. Diversified charging mode and output mode are optional. When PV priority mode is selected, utilization of green solar energy can be maximized to achieve energy saving and emission reduction. Switch to mains supply when the PV charging is not available. This mode maximizes the use of solar energy while maintaining battery power, suitable for use in the areas with relatively stable grid.
