The Mass Energy ME 3000SP inverter may not display information due to the following reasons:
1. Power Supply Issue – The inverter may not be turned on, or the DC & AC breakers may be off. Ensure the inverter is powered. 2. Connection Issue – If the CT connection has been changed, the setup procedure must be repeated. 3. Firmware Update Issue – If a firmware update fails, the inverter may not function properly. Ensure the update completes successfully and restart the inverter. 4. Screen Failure – If the LCD screen does not turn on after power is supplied, there might be a hardware malfunction.
Check power connections, restart the inverter, and verify successful firmware updates to resolve the issue.
1. ME3000SP Introduction ME3000SP is an AC coupled bi‐directional battery inverter. The customer can purchase batteries & ME3000SP as an energy storage add‐on to his/her existing renewable energy system. It can help to achieve optimal usage of renewable energy. ME 3000SP can control the bi‐directional flow of electric power, work under auto / manual & time‐of‐use (TOU) modes, charge / discharge the battery as per customer’s setting. In auto mode, ME3000SP will store surplus renewable energy into the battery & discharge battery to supply power to local load when renewable energy is not enough. ME3000SP is equipped with an LCD display and 4 buttons, friendly human machine interaction system. More importantly ME3000SP is stable, safe, and reliable. ...
2. Safety Notes Before installation, please make sure you read & understand this manual. ME3000SP strictly meets safety rules of design and testing. During the installation, operation and maintenance, operators should abide by local safety regulations. Improper operation may cause an electric shock or damage the equipment and properties. 2.1 Safety Notes Electrical installation and maintenance must be carried out by competent electricians according to local regulations. ...

4. Electrical Connection Be aware of electric shock and chemical hazards! Before connecting the battery, ensure the cable connectors have the correct polarity. Reversed polarity can damage ME3000SP! It’s recommended to install a rotary DC isolator (100A) between ME3000SP and batteries. Thus ME3000SP can be securely disconnected during installation/maintenance. It’s necessary to install a AC circuit breaker (25A) between ME3000SP and electrical grid. It is very important for system safety and efficient operation to use appropriate cable for electrical connection. Battery connection: AWG6 cable. Grid & Load connection: AWG12 cable. Make sure N wire is connected to PE wire while EPS (Emergency Power Supply) mode is enabled. Fig. 5 Wiring Schematic of Single Phase System ...
