SOLAX POWER PVR-18S (01) PDF MANUAL

The installation and maintenance can only be performed by qualified personnel who are licensed and/or satisfy state and local jurisdiction regulations, and have good knowledge of this manual and other related documents.

Before installing the device, carefully read, fully understand and strictly follow the detailed instruction of the installation manual and other related regulations.

Use insulated tools when installing the device. Individual protective tools must be worn during installation, electrical connection and maintenance.

Do not dispose of the device together with household waste.

Do not operate this device until it is isolated from on-site PV generation suppliers.

Only operate the device when it is technically faultless. Otherwise, electric shock or fire may occur.

Exposure to sunlight can result in the generation of high DC voltage by PV modules, which can lead to electric shock causing severe injuries or even death.

Never touch the positive or negative poles of the PV connecting device, and avoid touching both poles simultaneously.

Do not ground the positive or negative poles of the PV modules.

Only qualified personnel can perform the wiring of the PV modules.

The grounding cable must be well connected to ground. Incorrect connection may cause fatal electric shock! If not connected correctly, the device may be damaged when struck by lightning!

Do not open the enclosure in any case without authorization from SolaX. Unauthorized opening will void the warranty and cause lethal danger or serious injury due to electric shock.

The inverter, which connected in parallel mode with a PV Reverse Combiner Box, should be switched on before sunrise or after sunset.

When power on the system, the correct order is: switch on the PV Reverse Combiner Box, turn the inverter DC switch to ON, then turn the switch of the PV Combiner box to ON.

Touching the internal terminals of the device may result in electric shock or fire! Do not touch the terminals or conductors connected to the inverter or string.

The screws of the terminal must be tightened in place, otherwise the terminal would be heated and burned after a prolonged period.

Multi-strand copper core flame-retardant cables must be used, with the wire diameter not less than the recommended value.

The screw of the waterproof terminal must be tightened in place, otherwise it may cause water leakage.

Keep children away from the device.

Pay attention to the weight of the device. Personal injuries may be caused if not handled properly.

All the product labels and nameplate on the device shall be maintained clearly visible.

As for PVR-10S, you should connect 10 positive output terminals and 10 negative output terminals; as for PVR-24S, you should connect 24 positive output terminals and 24 negative output terminals; and other models in the same way.

The ambient temperature should be -40°C to +60°C.

The relative humidity shall be between 0-95%RH.

Install the device in a well-ventilated environment for heat dissipation. It is recommended to install an awning over the device if it is installed on a support outdoor.

Do not install the device in areas with flammable, explosive and corrosive materials or near combustibles and antennas.

For outdoor installation, precautions against direct sunlight, rain exposure and snow accumulation are recommended.

1. Mark the position of the mounting hole and drill.

2. Fix M8x20 screws, lugs, washers and nuts in order and tighten it.

Before electrical connection, make sure all switches and DC breaker are disconnected. Otherwise, the high voltage may cause electric shock, resulting in severe personal injuries or even death.

1. Use keys to open the PV Reverse Combiner Box.

2. Remove the PC Cover.

1. Strip the cable, sleeve the terminal onto the cable.

2. Crimp the cable to the Input terminal.

3. Dismantle the input cable gland.

4. Dismantle the M12 screw.

5. Insert the cable to the input cable gland in order. Pre-assemble the input cable gland and do not tighten it.

6. Insert the cable and input cable gland to the device and tighten the M12 screw.

7. Adjust the cable, and tighten the input cable gland. If the seal is not secure, it is recommended to add some fireproof mud inside the input cable gland.

During connection, pay attention to the polarity, and do not reverse it.

1. Strip the cable, sleeve the terminal onto the cable.

2. Crimp the cable to the output terminal.

3. Dismantle the output cable gland.

4. Insert the cable to the output cable gland in order. Pre-assemble the output cable gland and do not tighten it.

5. Insert the cable to the output cable gland and tighten the cable.

6. Adjust the cable, and tighten the output cable gland. The wiring procedure here takes PVR-24S as an example.

During connection, pay attention to the polarity, and do not reverse it.

1. Dismantle the grounding cable gland.

2. Insert the cable to the grounding cable gland. Pre-assemble the input cable gland and do not tighten it.

3. Insert the cable and grounding cable gland to the device. Tighten the terminal, adjust the cable, and tighten the output cable gland.

1. Install the PC cover.

2. Use the keys to lock the door. (Power on the system before locking the door for the first-time use)

During operation, please wear protective equipment and make sure that all cables has connected to the inverter.

1. Use keys to open the door.

2. Ensure that all switches are disconnected before proceeding.

3. Check that the positive and negative terminals of the PV Reverse Combiner Box are not reversed.

4. Use a multimeter to measure the voltage on the output side of the PV Reverse Combiner Box, ensure that the voltage of each circuit is basically equal and there is no negative voltage (wrong polarity will cause damage to the box and inverter!).

5. Turn the inverter DC switch to ON, then turn the switch of the PV Combiner box to ON.

6. Lock the door and pull out the key.

1. Use keys to open the door.

2. Disconnect the switch on the input side of the PV Reverse Combiner Box (if any). (Do not disconnect the DC switch of the inverter first, it is possible to cause damage to the PV Reverse Combiner Box and the inverter!)

3. Turn the switch of the PV Combiner box to OFF. Then turn the inverter DC switch to OFF.

4. Lock the door and pull out the key.

Once the fuse has blown, it cannot be restored and must be replaced immediately.

The fuse replacement must be of the same grade as the original one!

Do not check or replace the fuse with load! Installation and removal of the fuse must be proceeded with no load to avoid arc damage and personal injury.

1. Pull out the fuse cover.

2. Replace the fuse.

3. Close the fuse cover tightly.
