- User Manual (this document)
5. Installation
5.1 Mounting the Inverter
The inverter should be mounted vertically on a sturdy wall in an indoor, well-ventilated area, away from direct sunlight, heat sources, and flammable materials. Ensure sufficient clearance around the unit for proper airflow.
5.2 Wiring Connections
All wiring should be performed by a qualified electrician in accordance with local electrical codes and regulations. Ensure all power sources (grid, PV, battery) are disconnected before making any connections.
- Grid Input: Connect the utility grid AC power to the 'GRID INPUT' terminals (L, N, Ground).
- Generator Input: If using a generator, connect its AC output to the 'GEN INPUT' terminals (L, N, Ground). The inverter supports generator input.
- Battery Input: Connect the 48V battery bank to the 'BATTERY INPUT' terminals (POS, NEG). Ensure correct polarity.
- PV Input: Connect the solar panel array to the 'PV INPUT x2' terminals. The inverter has two independent MPPT trackers. Ensure PV input voltage does not exceed 900Vdc.
- AC Output: Connect your home's electrical load to the 'OUTPUT' terminals (L, N, Ground).
- Communication Ports: Use the RS232 or USB ports for connecting to a computer for monitoring and configuration. An 'Intelligent Slot' is also available for optional communication cards (e.g., WiFi, SNMP).
- Control Ports: The 'N.C./N.O./COM Dry Contact' can be used for a genset starter. A 'Battery Thermal Sensor' port is available for temperature compensation. The 'EPO' (Emergency Power Off) port provides a safety shutdown.
- PV DC Switch: Ensure this switch is in the 'OFF' position during installation and maintenance.
6. Operation
6.1 Control Panel
The inverter features an LCD display and function keys (Enter, Esc, Up, Down) for local monitoring and configuration. The LCD provides real-time information on system status, input/output voltages, currents, and power. Use the function keys to navigate menus and adjust programmable parameters.
6.2 Operating Modes
The MPI 5K PLUS supports three primary operating modes:
- Grid-Tie with Battery Backup: The inverter prioritizes solar power, uses battery backup during outages, and can feed excess power to the grid.
- Off-Grid Only: The inverter operates independently of the grid, drawing power from solar panels and batteries to supply local loads.
6.3 Programmable Parameters
The inverter allows for various parameters to be programmed, including battery charging voltage (bulk, float), low battery cut-off, AC input range, output voltage, and priority settings for solar, utility, and battery power. Refer to the detailed user manual (if available as PDF) for a complete list and instructions on parameter configuration.
7. Monitoring Software
The inverter comes with free monitoring software, typically provided on a CD. This software allows for remote monitoring of the inverter's performance, energy production, battery status, and system logs. It can also be used to configure programmable parameters from a computer.
7.1 Connection
Connect the inverter to your computer using the provided USB or RS232 communication cable. Install the monitoring software from the CD onto your computer.
7.2 Features
The software provides a graphical interface to visualize energy flow, historical data, and allows for advanced settings adjustments. Ensure your computer meets the minimum system requirements for the software.
8. Parallel Operation Guide (for MPI Hybrid Inverters Only)
The MPI 5K PLUS inverter supports parallel operation for increased power output and redundancy, allowing up to 6 units to work together. This guide outlines the two main steps for parallel setup.
8.1 Step 1: Prepare Wiring and OCPD (Overcurrent Protection Devices)
- Communication Cable: Connect the communication cable between all units according to the instructions.
- Current Sharing Cable: Connect the current sharing cable ONLY between inverters of the same phase. Parallel cables connect Male-to-Female, Female-to-Male, etc.
- Input Wiring: Connect the input wiring cables from the Utility, to the Load, and from the Battery to each inverter.
Important Safety Notes:
- A suitable breaker should be installed between all power sources (Grid, PV, and battery) and the inverter.
- The "AC OUTPUT" of the inverter should always be connected to the LOAD only. Connecting it elsewhere can cause damage.
8.2 Step 2: Program Software
- Ensure all units are properly wired. Double-check that all breakers are OFF and all Neutral wires from all units are connected together.
- Turn ON each unit individually and program each unit through the RS232 or USB port using the SolarPower or SolarPower Pro software.
- Specifically, enable the "Parallel for output" setting in the software for each unit.
- After programming all units, shut down all inverters and then turn them ON again for the settings to take effect.
