Notice：

PV Connection (Only apply for the model with solar charger)

CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter and PV modules.

WARNING! All wiring must be performed by a qualified personnel.

WARNING! It's very important for system safety and efficient operation to use appropriate cable for PV module connection. To reduce risk of injury, please use the proper recommended cable size as below.

PV Module Selection: (Only for the model with PWM solar charger)

When selecting proper PV modules, please be sure to consider below requirements first:

1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter.
   

   INVERTER MODEL	HPS12V1500VA	HPS24V1500VA HPS24V3000VA
   Rated Out Power	12V	24V
   Charging Current (PWM)	50Amax.
   Max. PV Array Open Circuit Voltage	55Vdc	80Vdc

2. Max. Power Voltage (Vmpp) of PV modules should be close to best Vmp of inverter or within Vmp range to get best performance. If one PV module can not meet this requirement, itS necessary to have several PV modules in series connection. Refer to below table.
   

   Model	Best Vmp	Vmp range
   HPS12V1500VA	15Vdc	15V~20V
   HPS24V1500VA	30Vdc	30V~40V
   HPS24V3000VA

Note: * Vmp: panel max power point voltage.

The PV charging efficiency is maximized while PV system voltage is close to Best Vmp.

Maximum PV module numbers in Series: Vmpp of PV module *Xpcs = Best Vmp of Inverter or Vmp range

PV module numbers in Parallel: Max. charging current of inverter / Impp

Total PV module numbers = maximum PV module numbers in series * PV module numbers in parallel

lake HPS12V1500VA inverter as an example to select proper PV modules. After considering Voc of PV module not exceeds 55Vdc and max. Vmpp of PV module close to 15Vdc or within 15Vdc ~ 20Vdcz we can choose PV module with below specification.

Product Overview(3KVA Model)

INSTALLATION

Unpacking and Inspection

Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should have received the following items inside of package:

• The unit x 1

• User manual x 1

• Communication cable x 1

• Software CD x 1

Preparation

Before connecting all wirings, please take off bottom cover by removing two screws as shown below.

Mounting the Unit

Consider the following points before selecting where to install:

• Do not mount the inverter on flammable construction materials.

• Mount on a solid surface

• Install this inverter at eye level in order to allow the LCD display to be read at all times.

• For proper air circulation to dissipate heat, allow a clearance of approx. 20 cm to the side and approx. 50 cm above and below the unit.

• The ambient temperature should be between 0°C and 55°C to ensure optimal operation.

• The recommended installation position is to be adhered to the wall vertically.

• Be sure to keep other objects and surfaces as shown in the diagram to guarantee sufficient heat dissipation and to have enough space for removing wires.

SUITABLE FOR MOUNHNG ON CONCRETE OR OTHER NON-COMBUSHBLE SURFACE ONLY.

Battery Connection

Battery Connection

CAUTION: For safety operation and regulation compliance, it金 requested to install a separate DC over-current protector or disconnect device between battery and inverter. It may not be requested to have a disconnect device in some applications, however it% still requested to have over-current protection installed. Please refer to typical amperage in below table as required fuse or breaker size.

WARNING! All wiring must be performed by a qualified personnel.

WARNING! It's very important for system safety and efficient operation to use appropriate cable for battery connection, lb reduce risk of injury, please use the proper recommended cable and terminal size as below.

Recommended battery cable and terminal size:

Please follow below steps to implement battery connection:

1. Assemble battery ring terminal based on recommended battery cable and terminal size.

2. 1.5KVA model supports 12VDC system or 24VDC, 3KVA model supports 24VDC system. Connect all battery packs as below chart. It台 suggested to connect at least lOOAh .

3. 

4. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are tightened with torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly

AC In put/Output Connection

CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between inverter and AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 10A forl.5KVA,32Afor 3KVA.

CAUTION!! There are two terminal blocks with ''IN" and ''OUT" markings. Please do NOT mis-connect input and output connectors.

WARNING! All wiring must be performed by a qualified personnel.

WARNING! It's very important for system safety and efficient operation to use appropriate cable for AC input connection. To reduce risk of injury^ please use the proper recommended cable size as below.

Suggested cable requirement for AC wires

Please follow below steps to implement AC input/output connection:

1. Before making AC input/output connection, be sure to open DC protector or disconnector first.

2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3 mm.

3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws. Be sure to connect PE protective conductor (@) first, k—Ground (yellow-green)

WARNING: Be sure that AC power source is disconnected before attempting to hardwire it to the unit.

4. Then, insert AC output wires according to polarities indicated on terminal block and tighten terminal screws. Be sure to connect PE protective conductor (®) first.

5. Make sure the wires are securely connected.

CAUTION: Important

Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely; it may cause utility short-circuited when these inverters are worked in parallel operation.

CAUTION: Appliances such as air conditioner are required at least 2^3 minutes to restart because it's required to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check manufacturer of air conditioner if it勺 equipped with time-delay function before installation. Otherwise, this inverter/charger will trig overload fault and cut off output to protect your appliance but sometimes it still causes internal damage to the air conditioner.

Final Assembly

After connecting all wirings, please put bottom cover back by screwing two screws as shown below.

Communication Connection

Please use supplied communication cable to connect to inverter and PC. Insert bundled CD into a computer and follow on-screen instruction to install the monitoring software. For the detailed software operation, please check user manual of software inside of CD.
