3. Installation
3.1 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:
- [1] RS485 cable
- [2] Communication cable
- [3] Cables
- [4] User manual
- [5] Guarantee card
Image shows four types of cables and a user manual. Item 1 is a black RS485 cable. Item 2 is a black communication cable. Item 3 shows two red and two black wires for battery connection. Item 4 is a user manual. Item 5 is a guarantee card.
3.2 Mounting the Unit
Consider the following points before selecting where to install:
- Do not mount the battery on flammable construction materials.
- The ambient temperature should be between 0°C and 45°C to ensure optimum 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 right diagram to guarantee sufficient heat dissipation and to have enough space for removing wires.
Please follow below steps to implement battery connection:
- Assemble battery ring terminal based on recommended battery cable terminal size.
- Connect all battery packs as units required. It's suggested to connect at least 2 sets for inverter larger than 2KVA in parallel connection.
Diagram shows the rear of the battery unit with numbered ports. It indicates the need for adequate ventilation space around the unit, showing clearance requirements.
3.3 Connection for Parallel Mode
The PC series battery support to be connected in parallel for expansion. If you need one more battery bank to work in parallel mode, connect the battery as shown in PIC 1.
Diagram shows a 'Main Circuit' box connected to three battery units in parallel. The batteries are labeled with model numbers BTCB0606/BTCB0303. Red and black wires connect the batteries in parallel, with positive terminals linked together and negative terminals linked together. The main circuit box is connected to these common positive and negative terminals. The diagram illustrates how to connect multiple battery units for increased capacity.
Step: The schematic diagram of the parallel connection of three battery packs is shown in Figure 1.
Note: After completing the above steps, arbitrarily select the positive and negative poles of one of the battery packs to output. After confirming the correct connection of the inverter, controller and battery, you can turn on any of the switches and use the battery group happily.
For pure off grid system, the PV awake wire need to be connected with MPPT charge controller if the battery pack is charged by solar panels only. The connection diagram as below :
Diagram shows an off-grid solar power system. It includes a solar panel array connected to an MPPT charge controller. The charge controller is connected to the battery unit. The battery unit is also connected to an inverter, which then powers household loads. The diagram highlights the PV awake wire connection between the charge controller and the battery.
4. Operation
Once the batteries are connected well, close the breaker to the ON block, press On/Off button to enable the output of the battery pack.
Diagram shows the front panel of the Felicitysolar battery unit. It features a power button labeled 'POWER' and several indicator lights. The Felicitysolar logo is visible at the top.
