design lithium battery system.
◼Mainly consists of one cabinet and multiple battery modules.
◼The nominal capacity of the battery is 2.4kWh, and the nominal voltage of the battery is 48V.
◼The single cabinet supports up to four 48V/50Ah battery modules in parallel.
◼Supports up to two cabinets in parallel and can be expanded to 19.2KWh.
◼Customized battery management system (BMS), real-time data acquisition, status monitoring
and control to ensure safe and reliable operation of the system.
The system has flexible configuration and high reliability, which can be widely applied to
household energy storage scenarios.
2.1.2 Inverter
◼220V Single-phase Pure sine wave inverter.
◼Self-consumption and feed-in to the grid.
◼Auto restart while AC is recovering.
◼Programmable supply priority for battery or grid.
◼Programmable multiple operation modes: On grid, off grid and UPS.
◼Configurable battery charging current/voltage based on applications by LCD setting.
◼Configurable AC/Solar/Generator Charger priority by LCD setting.
◼Compatible with mains voltage or generator power.

Picture 3-3 Adjust the mounting bracket
The original mounting bracket is suitable for 12, 16-inch installation space. If it is suitable for
installation of 20 and 24 inches, remove the screws in the red circle in the figure above, and move
the removed parts to the left and right by a screw hole position according to the direction of the
arrow to fix the screws. The adjusted bracket is suitable for installation space of 20 or 24 inches.
(3) Fixed installation bracket:
Place the mounting bracket on a suitable position on the wall, draw a mark on the mounting
hole with a pen, and drill a hole with a diameter of φ12 at a depth of 70mm; insert the expansion
screw seat into the hole and knock to the end; after unscrewing the screw, the mounting bracket is
fixed to the wall, Tighten the screws with a wrench.
Picture 3-4 Intent of the fixed mounting bracket

- Instruction Manual for ESS R050096 - 14
(4) Installing the cabinet: Hang the cabinet to the mounting bracket, fix the 4 screws removed in the
first step, and complete the installation.
Picture 3-5Install the battery cabinet
Note: When installing on the ground, the height of the wall drillhole positions must ensure that the
cabinet feet can touch the ground, and then adjust the feet locking nuts with a wrench.
Picture 3-6 Adjusting the feet
Note: If the battery packs have been installed in the cabinet, you can skip the following steps.

- Instruction Manual for ESS R050096 - 15
(5) Unscrew the fixing screws on the right door with a screwdriver, and remove the left and right
doors.
Picture 3-7 Open the side door
(6) Push the battery box into the cabinet one by one along the card slot, and fix the battery pack
with M6×12 screws.

3.3.2 Hybrid inverter Installation Guide
This Hybrid inverter is designed for outdoor use (IP65), Please make sure the installation site
meets below conditions:
◼Not in direct sunlight.
◼Not in areas where highly flammable materials are stored.
◼Not in potential explosive areas.
◼Not in the cool air directly.
◼Not near the television Antenna or antenna cable.
◼Not higher than altitude of about 2000 meters above sea level.
◼Not in environment of precipitation or humidity (>95%).
Please AVOID direct sunlight, rain exposure, snow laying up during installation and operation.
Before connecting all wires, please take off the metal cover by removing screws as shown below:
Positive and negative terminal

- Instruction Manual for ESS R050096 - 16
Considering the following points before selecting where to install:
◼Please select a vertical wall with load-bearing capacity for installation, suitable for
◼installation on concrete or other non-flammable surfaces, installation is shown below.
◼Install this inverter at eye level in order to allow the LCD display to be read at all times.
◼The ambient temperature should be between -25~60℃ to ensure optimal operation.
◼Be sure to keep other objects and surfaces as shown in the diagram to guarantee sufficient heat
dissipation and have enough space for removing wires.
For proper air circulation to dissipate heat, allow a clearance of approx. 500mm to the side.
And approx.500mm above and below the unit. And 1000mm to the front.
◼Mounting the inverter
Remember that this inverter is heavy! Please be careful when lifting out from the package.
