Symbol

Definition

Tip

Indicates any practical advice for reference

IMPORTANT: Indicates a critical tip during the operation, if ignored, may cause the

device to run in error.

CAUTION: Indicates potential hazards, if not avoided, may cause the device

damage.

WARNING: Indicates the danger of electric shock, if not avoided, would cause

would cause scalds.

Read the user manual carefully before any operation.

WARNING:

The entire system should be installed by professional and technical personnel.

2. Requirements for professional and technical personnel

Professionally trained.

Familiar with related safety specifications for the electrical system.

Read this manual carefully and master related safety cautions.

3. Professional and technical personnel is allowed to do

Install the HPS-AHL to a specified location.

Conduct trial operations for the HPS-AHL.

Operate and maintain the HPS-AHL.

4. Safety cautions before installation

CAUTION

When receiving the HPS-AHL, please check if there is any damage in transportation.

If you find any problem, please contact the transportation company or our company in

time.

CAUTION

When installing or moving the HPS-AHL, follow the instructions in the manual.

When installing the HPS-AHL, end-users must evaluate whether the operation

area exists arc danger.

WARNING

Keep the HPS-AHL out of the reach of children.

The HPS-AHL is only allowed for stand-alone operation. Connecting multiple units'

AC output in parallel or series is prohibited. Otherwise, the HPS-AHL may be

damaged.

5. Safety cautions for mechanical installation

WARNING

Before installation, confirm the HPS-AHL has no electrical connection.

Ensure enough heat dissipation space for the HPS-AHL before installation.

Do not install the HPS-AHL in humid, high salt spray, corrosion, greasy, flammable,

explosive, dust accumulative, or other severe environments.

Ensure the ground is flat and place the HPS-AHL horizontally.

6. Safety cautions for electrical connection

CAUTION

Check whether wiring connections are tight to avoid the danger of heat

accumulation due to loose connections.

The HPS-AHL shell shall be connected to the ground. The cross-section of the

connection wire should not be less than 4mm2

A fast-acting fuse or breaker, whose rated current is twice the HPS-AHL rated

input current, should be used between the external battery and the HPS-AHL.

The external and internal batteries can be connected in parallel

when their voltage are the same.

WARNING

The AC output terminal is only for the load connection. Do NOT connect it to

another power source or Utility. Otherwise, the HPS-AHL will be damaged. Turn off

the HPS-AHL before connecting the loads. And then, turn on the HPS-AHL again

after connecting the loads successfully.

It is strictly forbidden to connect a transformer or a load with a surge power (VA)

exceeding the overload power at the AC output port. Otherwise, damage will be

caused to the HPS-AHL.

The loads’ capacity of the HPS-AHL is limited by the discharge characteristics of

the lithium battery, and the final interpretation belongs to our company.

Both the utility input and AC output are of high voltage, do not touch the wiring

connection to avoid electric shock.

7. Safety cautions for HPS-AHL operation

WARNING

HOT

SURFACE

When the HPS-AHL works, the shell will generate much heat, and the temperature is

very high. Please do not touch it, and keep it far from the equipment susceptible to

high temperature.

CAUTION

When the HPS-AHL is working, please do not open the HPS-AHL cabinet to

operate.

When eliminating the fault that affects the safety performance of the HPS-AHL or

disconnecting the DC input, turn off the HPS-AHL switch and operate it after the

LCD is completely OFF.

8. The dangerous operations would cause an electric arc, fire, or explosion.

Touch the wire end that hasn't been insulation treated and may be electriferous.

Touch the wiring copper row, terminals, or internal modules that may be electriferous.

The connection of the power cable is loose.

Screw or other spare parts inadvertently falls into the HPS-AHL.

Improper operations are carried out by untrained non-professional or technical personnel.

WARNING

Once an accident occurs, it must be handled by professional and technical personnel.

Improper operations would cause more serious accidents.

9. Safety cautions for stopping the HPS-AHL

First, turn off the AC output and disconnect the utility input breakers. Then, turn off the DC switch.

After the input and output wires are disconnected for ten minutes, the internal conductive modules

can be touched.

No maintenance parts in the HPS-AHL. If maintenance service is required, please get in touch with

our after-sales service personnel.

WARNING

Do NOT touch or open the shell after the HPS-AHL is powered off within ten minutes.

10. Safety cautions for maintenance

It is recommended to check the HPS-AHL with testing equipment to ensure there is no voltage and

current.

When conducting the electrical connection and maintenance, post a temporary warning sign or put

up barriers to prevent unrelated personnel from entering the electrical connection or maintenance

area.

Improper maintenance of the HPS-AHL may cause personal injury or equipment damage;

It is recommended to wear an antistatic wrist strap or avoid unnecessary contact with the circuit

board.

CAUTION

The safety mark, warning label, and nameplate on the HPS-AHL should be visible, not

removed or covered.

Disclaimers

The warranty does not apply to the following conditions:

Damage caused by improper use or inappropriate environment (such as the humid, high salt spray,

corrosion, greasy, flammable, explosive, dust accumulative, or other severe environments).

The actual current/voltage/power exceeds the limit value of the HPS-AHL.

Damage caused by working temperature exceeding the rated range.

Arc, fire, explosion, and other accidents caused by failure to follow the HPS-AHL stickers or manual

instructions.

Unauthorized dismantling or attempted repair.

Damage caused by force majeure.

Damage occurred during transportation or handling.

1 General Information

1.1 Overview

HPS-AHL series, upgrade home battery backup that support utility charging, oil generator charging, solar

charging, utility output, inverter output, and energy management. With a built-in LiFePO4 lithium battery,

the HPS-AHL home battery backup can meet customers' energy storage needs.

The DSP chip with an advanced control algorithm brings high response speed, reliability, and conversion

efficiency.

Multiple charging and output modes to suit different scenarios.

Three-stage charging method (Bulk Charging, Constant Charging, and Float Charging) is adopted to

ensure battery safety.

The large lattice LCD shows the operational status and full parameters.

The communication interface with the standard Modbus protocol allows end-users to expand their

applications and is suitable for different monitoring requirements.

The new optimized MPPT tracking technology can fast-track the PV array's Max. power point in various

situations and obtain the maximum energy in real time.

Adopting the advanced control algorithm, the AC to DC charging process brings the full digital PFC and

dual closed-loop voltage-current control. It enables the input power factor close to 1 and improves the

control accuracy.

The fully smart digital DC to AC inverting process adopts the advanced SPWM technology, outputs a pure

sine wave, and converts the DC power to AC power. It is suitable for household appliances, power tools,

industrial equipment, audio systems, and other electronics.

Multiple DC output ports can connect different DC loads, including 5VDC/3A port*2pcs and 12VDC/2A

port*2pcs. In addition, two USB-C dedicated ports (5VDC/3A and 100W PD) meet the fast charging of

mobile phones and notebooks.

End-users can choose energy sources according to actual needs to maximize solar energy utilization and

flexibly take the Utility as a supplement in the hybrid system. This HPS-AHL home battery backup

provides high-quality, high-stability, and high-reliability electric energy to the end-users by improving the

solar system's power supply efficiency.

Features

Circuit breaker on battery output for battery safety.

Advanced MPPT technology, with Max. tracking efficiency higher than 99.5%.

Circuit breaker on PV input for equipment safety.
