2.1. Суурилуулах орчин

The inverter should be installed in a dry, temperature-appropriate, and well-ventilated room. Ensure a gap of at least 20cm on both sides of the inverter and about 50cm at the top and bottom to allow for adequate air circulation and heat dissipation. Securely fix the inverter to the wall using the provided mounting bracket and screws.

2.2. Утасны холболт

Proper wiring is crucial for safe and efficient operation. Always ensure correct polarity for DC connections and proper grounding. Refer to the wiring diagrams below for detailed instructions.

Figure 2: General wiring diagram and technical specifications for the inverter system.

2.2.1. Зайны холболт

Connect the 48V battery system (compatible with Flooded, LiCoMnNiO2, LiFePO4, AGM, Gel types) to the inverter's battery terminals. Use appropriate gauge wires (e.g., 2AWG for battery connections) and ensure positive terminals connect to positive and negative to negative. For safety, install a 200A DC circuit breaker for the battery line.

2.2.2. PV Input Connection

Connect your solar PV array to the PV input terminals. The inverter features a 120A MPPT charge controller. Ensure the PV input voltage range is 60-105VDC and maximum PV input power is 6400W. Use appropriate gauge wires (e.g., 12AWG for PV input).

2.2.3. AC Input/Output Connections

The inverter supports dual voltage output (110V/220V) and split-phase operation. Connect the AC input from utility or generator and AC output to your loads. Use appropriate gauge wires (e.g., 10AWG for AC input/output). It is important to have a separate circuit breaker for each input and output line for safety and easier maintenance. Ensure the inverter is properly grounded using the grounding port on the unit, keeping the grounding point as close as possible to the inverter for maximum effectiveness.

5. Засвар үйлчилгээ

To ensure the longevity and optimal performance of your PowMr inverter, regular maintenance is recommended:

• Цэвэрлэгээ: Keep the inverter's exterior clean and free from dust. The anti-corrosion and dust-proof design helps, but periodic cleaning of vents is advisable to maintain proper airflow for the dual cooling fans.
• Холболтын шалгалт: Periodically inspect all wiring connections (DC input, AC input, AC output, battery, and grounding) to ensure they are secure and free from corrosion.
• Байгаль орчны нөхцөл: Ensure the installation environment remains within specified temperature and humidity ranges. Avoid exposing the inverter to direct sunlight or excessive moisture.

6. Алдаа засах

The inverter is equipped with an LCD screen and LED indicators to display system status and fault conditions. If an issue arises, refer to the display for error codes or indicator patterns.

• Цахилгаан/дэлгэц байхгүй: Check all circuit breakers (AC input, AC output, DC battery) and ensure they are in the ON position. Verify battery connections and voltage.
• Хэт ачааллын хамгаалалт: If an overload occurs (peak power 15000W, rated 5000W), the inverter may shut down. Reduce the connected load and restart the inverter.
• Ботьtage/Reverse Protection: The inverter has built-in protections against incorrect voltage and reverse polarity. If a fault is indicated, immediately check wiring for correct polarity and voltage түвшин.
• Богино залгааны хамгаалалт: In case of a short circuit, the inverter will activate protection. Identify and resolve the short circuit before restarting.
