This is a multi-function off-grid home energy storage system, integrated with MPPT solar charging
controller, sine wave inverter, UPS function module and energy storage battery, which is very
suitable for off-grid backup power supply and self-use.
The entire system also requires other equipment for complete operation, such as photovoltaic
modules, generators or utility grids. With this device, users can monitor the running state of the
system through their mobile phones or websites anytime and anywhere.
2.1 Features
* Rated function 3KW / 5KW, power factor is 1
* MPPT solar charging controller maximizes solar panel output
* High frequency inverter is small in size and light in weight
* Pure sine wave AC output
* Overload, short circuit and deep discharge protection
* Configurable AC / solar input / battery priority via LCD settings
* Compatible with grid and generator inputs
* WIFI / GPRS remote monitoring (optional)
* AP-5096 can realize parallel operation (optional)

3.0 Installation
3.1 Unpacking and Inspection
Please check the equipment before installation to make sure there are no damaged items in the
package. You will receive the following items in the package:
* Machine X1,
* User manual X1
* WIFI/GPRS communication module X1 (optional)
3.2 Installation of Machine
Before choosing the installation location, consider the following:
*Do not install the machine on flammable building materials.
* Install on solid ground and place against the wall.
* To ensure optimal operating conditions, the ambient temperature should be 0℃~55℃.
* Make sure there is some free space around the equipment to ensure adequate cooling and
enough space to move the wires.
3.3 Ac Input/Output Connection
Two sockets marked "AC Input" and "AC Output" are used to connect the utility grid input and
load output. Insert the corresponding connector.

Note: it will take at least 2 to 3 minutes to restart an electrical appliance such as an air
conditioner, as there needs to be enough time to balance the refrigerant gas in the
circuit. If a power short circuit occurs within a short period of time and the power is
restored, it will cause damage to the device you are connected to. To prevent this kind of
damage, please confirm with the air conditioner manufacturer before installation
whether there is delay function, otherwise, the equipment will trigger overload fault and
cut off the output to protect your equipment, and may cause damage to the inside of the
air conditioner.
Warning! Ac input and output connections using appropriate cables are
important for safe and efficient operation of the system. To reduce the risk of
injury, use the correct cable size recommended below.

3.4 PV connection
Check the correctness of the cable connection between the PV component and the PV input
connector, then connect the positive pole of the cable to the positive pole of the device PV input
connector, and the negative pole of the cable to the negative pole of the device PV input
connector to ensure that the connection is firm and reliable.
Note: Before connecting the PV module, make sure that the maximum output voltage of the PV
module does not exceed the maximum dc voltage allowed by the device.
Warning! The use of suitable cables to connect PV modules is important for safe and efficient
operation of the system. To reduce the risk of injury, use the normal cable size recommended
below.
