This document provides essential instructions for the 2E 11KW Twin Solar Inverter / Charger. It covers system installation, electrical wiring, configuration, and troubleshooting. Always ensure all electrical work is performed by qualified personnel.
Device Overview
The 11KW Twin is a multifunctional inverter combining inverter, solar charger, and battery charger functions. It features a detachable LCD control module, built-in Wi-Fi for mobile monitoring, and supports parallel operation.
Installation
Ensure the unit is mounted on a non-flammable surface (concrete or similar). Maintain at least 20cm of clearance on the sides and 50cm above and below for proper heat dissipation. The operating temperature range is 0°C to 55°C.
Wiring
- Battery Connection: Use recommended 1*3/0AWG cables. Ensure correct polarity and tighten terminals to 5 Nm.
- AC Input/Output: Connect AC input and output according to the markings. Ensure the PE (ground) wire is connected first.
- PV Connection: Use only monocrystalline, polycrystalline (Class A), or CIGS modules. Ensure the PV array voltage does not exceed 500V DC.
Operation
Use the power switch on the display panel to turn the unit on. The LCD provides real-time status, including input/output voltage, battery capacity, and load percentage. Use the function keys to navigate menus and configure settings.
LCD Settings
To enter settings, hold the Enter button for 3 seconds. Use the Up/Down keys to select programs. Key settings include:
- 01: Output source priority (Utility, Solar, or SBU).
- 02: Maximum charging current.
- 05: Battery type selection.
- 28: Parallel/3-phase operation mode.
Troubleshooting
The unit displays fault codes on the LCD. Common issues include:
- F01: Fan blocked.
- F02: Over-temperature.
- F03/F04: Battery voltage too high/low.
- F05: Output short circuit.
For persistent issues, contact the authorized service center: IP LOGIC, Kyiv, Ukraine. Phone: 0 800 300 345; (044) 230 34 84; (044) 390 55 12. Website: https://service.erc.ua
