2Product Introduction
2.1 System diagram
The RX-2505AC system uses the grid and battery to ensure the continuous power supply to important
loads. The system allows users to store the energy from grid into the battery, and send the stored energy to
the grid when needed. It can also provide backup power during apower outage.
Figure 2-1 shows the application of the RX-2505AC all-in-one energy storage system. RX-2505AC
contains the inverter and battery storage modules. It is important to keep the installation environment well
ventilated and take necessary measures to control the ambient temperature to avoid the risk of explosion
caused by excessive battery temperature.

2. Align the hole template on the installation surface and drill holeswith adiameter of 8mm and adepth of
40mm on the wall.
3. Install the m6x60 expansion screwsinto the previously drilled holes.
4. Secure the fixing bracket to the wall using asocket wrench and tighten the expansion bolts.
5. Align the unit with the fixing bracket on the wall and lift the unit on to the bracket by lowering it into the
holes.
6. Prepare the unit for installation of cabling.
4.3 Earth Connection

5Cable Connection
5.1 Connect cables to the AC grid side and off-grid side
RX-2505AC has terminals for on and off-grid. As shown in Figure 5-1, the left terminal is the off-grid
terminal (EPS) and the right terminal is the on-grid terminal. An independent AC circuit breaker must be
configured for each circuit to safely disconnect then system. When selecting the external cable, consider
the hole in the cable gland.The table below is a recommendation for cable selection. Engineers should
refer to local standards to select cables. Cable length is generally 2 to 10 meters, long cable will lead to
voltage drop from the rated value, consequently requiring an increase of the cross-sectional area.
Recommended specifications of AC circuit breaker:
The following table lists the recommended specifications of AC cables:

Requirements
1.Install anAC circuit breaker between the inverter and the grid before connecting the system to the grid.
2. Grid voltage and grid frequency should be within the allowable range of inverter operation.
Steps
1. First, prepare the required connecting wires according to the following. It is recommended that
the live wire be red, the ground wire be black, and the safety earth wire be yellow and green.
2. Remove the cover of the terminal
3.Note the wiring terminals

Rev 20220606
RX2505AC
Page 20 of 35
4.Connect the cable to the corresponding terminal according to the marking and tighten the screws:
5. Follow similar steps to connect the off-grid side, ensure that all wires are securely connected and
reinstall the cover plate.
The recommended connection is as follows:
This diagram is an example for an installation where Neutral connects to PE in the switchboard.
Example countries that have this regulation: Australia, New Zealand. Please follow local wiring regulations!
Note:
The battery inverter does not have an internal RCD as it is isolated. If an external RCD breaker is mandatory
in the country of installation, it must be a type A RCD with the rating residual current not more than 30mA.
