SOLAX POWER PVR-12S (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;

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. SolaX shall not be liable for any consequences caused by the violation of the installation, and operation regulations specified in this document.

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

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!

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

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.

The packing list includes:

The following additional materials are required:

* For copper input cables, please use copper terminals, for aluminium input cables, please use aluminium-to-copper terminals.

The ambient temperature: -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.

Exposure to direct sunlight raises the temperature inside the device. This temperaturerise poses no safety risks, but may impact the device performance.

Mark the position of the mounting hole and drill. The drilling specifications are: Depth: 20 mm, Diameter: 10 mm.

Fix M8x20 screws, lugs, washers and nuts in order and tighten it. The recommended torque for M8 is 10.8-13.2 N-m.

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.

Use keys to open the PV Reverse Combiner Box.

Remove the PC Cover.

Strip 35 mm of the cable, then sleeve the terminal onto the cable. Crimp the cable to the Input terminal. The recommended torque for M5 is 0.8 N-m.

Dismantle the input cable gland. Dismantle the M12 screw (torque 25 N-m). Insert the cable into the input cable gland in order. Pre-assemble the input cable gland but do not tighten it. Insert the cable and input cable gland into the device and tighten the M12 screw (torque 25 N-m). Adjust the cable, and hand 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.

Strip 15 mm of the cable, then sleeve the terminal onto the cable. Crimp the cable to the output terminal.

Dismantle the output cable gland (torque 1-2 N-m). Insert the cable into the output cable gland in order. Pre-assemble the output cable gland but do not tighten it. Insert the cable into the output cable gland and tighten the cable (torque 3 N-m). Adjust the cable, and tighten the output cable gland (torque 1-2 N-m).

Strip the cable, sleeve the terminal, and crimp it. For the grounding cable (10-14 mm²), the heat-shrink tubing length C should be A+2 cm, where A is the stripped wire length. Dismantle the grounding cable gland (torque 4-6 N-m). Insert the cable into the grounding cable gland. Pre-assemble the input cable gland and do not tighten it. Insert the cable and grounding cable gland to the device. Tighten the terminal (torque 3 N-m), adjust the cable, and tighten the output cable gland (torque 4-6 N-m).

Install the PC cover (torque 0.8 N-m).

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.

Step 1: Use keys to open the door.

Step 2: Ensure that all switches are disconnected before proceeding.

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

Step 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!).

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

Step 6: Lock the door and pull out the key.

Step 1: Use keys to open the door.

Step 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!)

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

Step 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.

Step 1: Pull out the fuse cover.

Step 2: Replace the fuse.

Step 3: Close the fuse cover tightly.
