Therefore, if a communication error shows up on display:

1) Check if your data cable is the correct type.

2) Check if you are plugging the cable into the correct sockets.

Usually, RS 485 is employed, but some battery manufacturers use others.

In some types of lithium batteries, the BMS cannot be controlled by Sunsynk inverter. In this case, treat

the battery as a lead-acid type and set the charging and discharging protocol as per the battery manufacturer

specification.

IMPORTANT:

When not using communications between battery and inverter, never overcharge your battery bank

(current and voltage). Many lithium batteries are limited to 100A. Some can be both higher and lower.

Therefore, ensure that voltage and current specifications provided by the battery manufacturer are followed.

If you are using lead-acid batteries, then a good rule of thumb is C x 0.1, which means that the maximum

charge or discharge you can apply to the battery is 10% of the Ah rating of the overall battery array. For

example, a 200Ah battery array composed of 4 x 200 power batteries in series has a maximum charge and

discharge of 20A. Then, you can check Table 1 to select the cable size and fuse rating remembering to follow

the recommendations of the battery manufacturers to ensure that the cable is thick enough to support the

current and that a proper fuse is used.

3.3. AC GRID CONNECTION

The inverter connection to the mains depends a lot on the installation type. However, the mains should

always be connected to the grid connection via any suitable protection device.

IMPORTANT:

If using the inverter without batteries, only use the grid connection. Do not connect anything to the

'AUX/GEN' connection because this will cause problems.

If you connect the inverter to a system with no grid available, all essential and nonessential loads will be

connected via the 'LOAD' output. Therefore, the inverter will operate in ‘Island Mode.’ In this situation, you
